Effects of ETC moving to SHA3

0xBitcoin might experience some benefits from ETC's recent decision to go to SHA3.
For one thing, if ETC developers turn their minds toward SHA3 GPU mining, it seems likely that they'll be very interested in the optimization work already done by Lt. Tofu and Azlehria on Cosmic and Nabiki. But they may also spot additional optimizations, which could most likely be ported back into our miners!
For another thing, since ETC has a larger community than 0xBitcoin's, it's likely that they have people with very diverse skills. As they turn their minds toward SHA3 on FPGAs, I anticipate they will be choosing FPGA boards and writing software for them that probably will not be very difficult to alter to mine 0xBitcoin! Practically speaking, this may result in a new era of mining where a respectable hash rate can be achieved with much less electricity expense.
Basically, if people with EE or hardware development backgrounds in the ETC community pin down some of the variables involved, like development board, it seems very likely that we will be able to get FPGAs mining 0xBitcoin quickly.
We recently exchanged some nice words with Alex Tsankov. He revealed he is doing work that may allow merge mining ETC and other projects like 0xBitcoin. I don't know how good this will be, but it's hard for me to see how this could be a bad thing. It's really great to have nice words from Alex, because he seems like a very smart dude who is very open to collaboration.
I have joined the ETC Discord (edit: link removed for just-Reddit-things reasons, you'll have no trouble finding it) and will be watching for opportunities to tell people there about our miners if they don't know, and watching for info about their developments on SHA3 miners.

A Software Engineer's Explanation of Server Ticks/FPS, the Message Pump, and Server Meshing

Since people liked my last post about the SQ42 report, I thought I would do another about the recent comment about server ticks https://robertsspaceindustries.com/spectrum/community/SC/forum/50259/thread/end-goal-server-tick-rate/2872293
To understand how this works, you must first understand the Message Pump. This is basically the heart beat of an application. It is a loop from which there is no escape, so long as the application runs. All applications have an "entry point" that initially gets called. If you've ever taken Computer Science 101, it would be your "main" function. For a console application, you enter main, it does some things, and then when it leaves main, the application closes. In an application with a graphical user interface, that loop has to regularly call a Render or Draw function that draws the UI. This happens on the Render Thread. In a regular client application your Message Pump will look something like this:
while(IsApplicationRunning) { //loop while application is meant to run HandleKeyboardInputs(); //check to see if any keyboard events have occured HandleMouseInputs(); //check to see if any mouse events have occurred, hittest children HandleSizeChanges(); //check if the window has resized, resize children to fit Render(); //recursively render all child controls } 
Each function call within the loop will call entire hierarchies of functionality. This same basic principal applies to a server as well. I am using my imagination, as I have never audited the Star Citizen codebase, but its message pump would look something like
while(IsServerOnline) { //loop while server is meant to run HandleOrbitalRotation(); //update position of all planets around the sun HandleNPCRoutines(); //update position/animations of all NPCs SynchronizePlayerLocations(); //receive player location packets and update //internal locations CheckForIssues(); //check all object positions and ensure no conflicts UpdatePlayerLocations(); //send new location data of all objects to connected //players } 
This is only the most basic sort of functionality, that doesn't factor in things like Server Object Container Streaming or Meshing or object persistence.
Each iteration of the Message Pump is a frame. These frames are calculated by having a Stopwatch and taking averages of how long it takes each frame to complete across a defined sample size. If you have a target frame rate, like 30fps for instance, subroutines can be prioritized to try to either run on the current frame, or be skipped, based on how much load is put on the servers.
My current understanding, based on Star Citizen's published material, is that there is presently one server for every 50 players, and that server handles an entire star system. Having one server for every 50 players right now is fine, and that number can hopefully be increased as optimizations happen within the code.
The important part is modifying the server code so that they can separate different Object Containers to separate physical server hardware. This would allow them to, for instance, have one server, with its own message pump, handle Port Olisar, for up to 50 players. For v0 of server meshing, I would imagine that, when the 51st player comes to PO, they would have to spin up a new server for that person of PO, and they would be on their own. When the player count goes back below 50, that server can go back to sleep and is available to be repurposed for whatever other area needs it, dynamically. As players leave PO, and go into space, each part of space could have dedicated servers for that area. The same goes for planets, or cities. Each would be its own Object Container, each Object Container could contain smaller Object Containers, so that as players move around, servers would seamlessly spin up or down to host content for the players. Technically, one server could even host multiple separate Object Containers if they both have low player counts.
This would go a very long way towards making the universe feel full and connected. To start out with, you might still only find a maximum of 50 people on Daymar, but you might also find 50 people on Yela, or ArcCorp. Each place could be full, with the game client switching servers when going to different areas. Server Object Container Streaming is what enables this. It is just a matter of handling the trade off between servers, and keeping everything synchronized. I recognize that the posts that CIG makes on the subject are often hard to understand for laymen, but these posts make me feel confident that they are making progress and heading in a meaningful direction toward the end goal of having us seamlessly switch between servers on the fly.
One thing that I have no heard anything about is the transition towards specialized physical hardware for handling some of these large-scale server-side operations. If they are using regular CPU/GPU operations, performance could be *vastly* improved by creating FPGAs or ASICs that could perform calculations with greater alacrity than a GPU could ever hope to. This is the type of hardware used in medical devices, data centers, or bitcoin mining.
I wrote this up purely to help people understand some aspects of software engineer, and no part of it is meant to be so specific that you should interpret it to be exactly how something works. I am trying to provide a high level, easy to understand, idea of some very complex concepts.
If there is any other part of development that you would like me to comment on feel free to @ me with VerdantNonsense :) Stay safe out there.

Skepticism Sunday – July 08, 2018

Please stay on topic: this post is only for comments discussing the uncertainties, shortcomings, and concerns some may have about Monero.
NOT the positive aspects of it.
Discussion can relate to the technology itself or economics.
Talk about community and price is not wanted, but some discussion about it maybe allowed if it relates well.
Be as respectful and nice as possible. This discussion has potential to be more emotionally charged as it may bring up issues that are extremely upsetting: many people are not only financially but emotionally invested in the ideas and tools around Monero.
It's better to keep it calm then to stir the pot, so don't talk down to people, insult them for spelling/grammar, personal insults, etc. This should only be calm rational discussion about the technical and economic aspects of Monero.
"Do unto others 20% better than you'd expect them to do unto you to correct subjective error." - Linus Pauling
How it works:
Post your concerns about Monero in reply to this main post.
If you can address these concerns, or add further details to them - reply to that comment. This will make it easily sortable
Upvote the comments that are the most valid criticisms of it that have few or no real honest solutions/answers to them.
The comment that mentions the biggest problems of Monero should have the most karma.
As a community, as developers, we need to know about them. Even if they make us feel bad, we got to upvote them.

How are FPGAs used in trading?

A field-programmable gate array (FPGA) is a chip that can be programmed to suit whatever purpose you want, as often as you want it and wherever you need it. FPGAs provide multiple advantages, including low latency, high throughput and energy efficiency.
To fully understand what FPGAs offer, imagine a performance spectrum. At one end, you have the central processing unit (CPU), which offers a generic set of instructions that can be combined to carry out an array of different tasks. This makes a CPU extremely flexible, and its behaviour can be defined through software. However, CPUs are also slow because they have to select from the available generic instructions to complete each task. In a sense, they’re a “jack of all trades, but a master of none”.
At the other end of the spectrum sit application-specific integrated circuits (ASICs). These are potentially much faster because they have been built with a single task in mind, making them a “master of one trade”. This is the kind of chip people use to mine bitcoin, for example. The downside of ASICs is that they can’t be changed, and they cost time and money to develop. FPGAs offer a perfect middle ground: they can be significantly faster than a CPU and are more flexible than ASICs.
FPGAs contain thousands, sometimes even millions, of so-called core logic blocks (CLBs). These blocks can be configured and combined to process any task that can be solved by a CPU. Compared with a CPU, FPGAs aren’t burdened by surplus hardware that would otherwise slow you down. They can therefore be used to carry out specific tasks quickly and effectively, and can even process several tasks simultaneously. These characteristics make them popular across a wide range of sectors, from aerospace to medical engineering and security systems, and of course finance.
How are FPGAs used in the financial services sector?
Speed and versatility are particularly important when buying or selling stocks and other securities. In the era of electronic trading, decisions are made in the blink of an eye. As prices change and orders come and go, companies are fed new information from exchanges and other sources via high-speed networks. This information arrives at high speeds, with time measured in nanoseconds. The sheer volume and speed of data demands a high bandwidth to process it all. Specialized trading algorithms make use of the new information in order to make trades. FPGAs provide the perfect platform to develop these applications, as they allow you to bypass non-essential software as well as generic-purpose hardware.
How do market makers use FPGAs to provide liquidity?
As a market maker, IMC provides liquidity to buyers and sellers of financial instruments. This requires us to price every instrument we trade and to react to the market accordingly. Valuation is a view on what the price of an asset should be, which is handled by our traders and our automated pricing algorithms. When a counterpart wants to buy or sell an asset on a trading venue, our role is to always be there and offer, or bid, a fair price for the asset. FPGAs enable us to perform this key function in the most efficient way possible.
At IMC, we keep a close eye on emerging technologies that can potentially improve our business. We began working with FPGAs more than a decade ago and are constantly exploring ways to develop this evolving technology. We work in a competitive industry, so our engineers have to be on their toes to make sure we’re continuously improving.
What does an FPGA engineer do?
Being an FPGA engineer is all about learning and identifying new solutions to challenges as they arise. A software developer can write code in a software language and know within seconds whether it works, and so deploy it quickly. However, the code will have to go through several abstraction layers and generic hardware components. Although you can deploy the code quickly, you do not get the fastest possible outcome.
As an FPGA engineer, it may take two to three hours of compilation time before you know whether your adjustment will result in the outcome you want. However, you can increase performance at the cost of more engineering time. The day-to-day challenge you face is how to make the process as efficient as possible with the given trade-offs while pushing the boundaries of the FPGA technology.
Skills needed to be an FPGA engineer
Things change extremely rapidly in the trading world, and agility is the name of the game. Unsurprisingly, FPGA engineers tend to enjoy a challenge. To work as an FGPA engineer at a company like IMC, you have to be a great problem-solver, a quick learner and highly adaptable.
What makes IMC a great fit for an FPGA engineer?
IMC offers a great team dynamic. We are a smaller company than many larger technology or finance houses, and we operate very much like a family unit. This means that, as a graduate engineer, you’ll never be far from the action, and you’ll be able to make an impact from day one.
Another key difference is that you’ll get to see the final outcome of your work. If you come up with an idea, we’ll give you the chance to make it work. If it does, you’ll see the results put into practice in a matter of days, which is always a great feeling. If it doesn’t, you’ll get to find out why – so there’s an opportunity to learn and improve for next time.
Ultimately, working at IMC is about having skin in the game. You’ll be entrusted with making your own decisions. And you’ll be working side by side with super smart people who are open-minded and always interested in hearing your ideas. Market making is a technology-dependent process, and we’re all in this together.

Transcript of discussion between an ASIC designer and several proof-of-work designers from #monero-pow channel on Freenode this morning

[08:07:01] lukminer contains precompiled cn/r math sequences for some blocks: https://lukminer.org/2019/03/09/oh-kay-v4r-here-we-come/
[08:07:11] try that with RandomX :P
[08:09:00] tevador: are you ready for some RandomX feedback? it looks like the CNv4 is slowly stabilizing, hashrate comes down...
[08:09:07] how does it even make sense to precompile it?
[08:09:14] mine 1% faster for 2 minutes?
[08:09:35] naturally we think the entire asic-resistance strategy is doomed to fail :) but that's a high-level thing, who knows. people may think it's great.
[08:09:49] about RandomX: looks like the cache size was chosen to make it GPU-hard
[08:09:56] looking forward to more docs
[08:11:38] after initial skimming, I would think it's possible to make a 10x asic for RandomX. But at least for us, we will only make an ASIC if there is not a total ASIC hostility there in the first place. That's better for the secret miners then.
[08:13:12] What I propose is this: we are working on an Ethash ASIC right now, and once we have that working, we would invite tevador or whoever wants to come to HK/Shenzhen and we walk you guys through how we would make a RandomX ASIC. You can then process this input in any way you like. Something like that.
[08:13:49] unless asics (or other accelerators) re-emerge on XMR faster than expected, it looks like there is a little bit of time before RandomX rollout
[08:14:22] 10x in what measure? $/hash or watt/hash?
[08:14:46] watt/hash
[08:15:19] so you can make 10 times more efficient double precisio FPU?
[08:16:02] like I said let's try to be productive. You are having me here, let's work together!
[08:16:15] continue with RandomX, publish more docs. that's always helpful.
[08:16:37] I'm trying to understand how it's possible at all. Why AMD/Intel are so inefficient at running FP calculations?
[08:18:05] midipoet ([email protected]/web/irccloud.com/x-vszshqqxwybvtsjm) has joined #monero-pow
[08:18:17] hardware development works the other way round. We start with 1) math then 2) optimization priority 3) hw/sw boundary 4) IP selection 5) physical implementation
[08:22:32] This still doesn't explain at which point you get 10x
[08:23:07] Weren't you the ones claiming "We can accelerate ProgPoW by a factor of 3x to 8x." ? I find it hard to believe too.
[08:30:20] sure
[08:30:26] so my idea: first we finish our current chip
[08:30:35] from simulation to silicon :)
[08:30:40] we love this stuff... we do it anyway
[08:30:59] now we have a communication channel, and we don't call each other names immediately anymore: big progress!
[08:31:06] you know, we russians have a saying "it was smooth on paper, but they forgot about ravines"
[08:31:12] So I need a bit more details
[08:31:16] ha ha. good!
[08:31:31] that's why I want to avoid to just make claims
[08:31:34] let's work
[08:31:40] RandomX comes in Sep/Oct, right?
[08:31:45] Maybe
[08:32:20] We need to audit it first
[08:32:31] ok
[08:32:59] we don't make chips to prove sw devs that their assumptions about hardware are wrong. especially not if these guys then promptly hardfork and move to the next wrong assumption :)
[08:33:10] from the outside, this only means that hw & sw are devaluing each other
[08:33:24] neither of us should do this
[08:33:47] we are making chips that can hopefully accelerate more crypto ops in the future
[08:33:52] signing, verifying, proving, etc.
[08:34:02] PoW is just a feature like others
[08:34:18] sech1: is it easy for you to come to Hong Kong? (visa-wise)
[08:34:20] or difficult?
[08:34:33] or are you there sometimes?
[08:34:41] It's kind of far away
[08:35:13] we are looking forward to more RandomX docs. that's the first step.
[08:35:31] I want to avoid that we have some meme "Linzhi says they can accelerate XYZ by factor x" .... "ha ha ha"
[08:35:37] right? we don't want that :)
[08:35:39] doc is almost finished
[08:35:40] What docs do you need? It's described pretty good
[08:35:41] so I better say nothing now
[08:35:50] we focus on our Ethash chip
[08:36:05] then based on that, we are happy to walk interested people through the design and what else it can do
[08:36:22] that's a better approach from my view than making claims that are laughed away (rightfully so, because no silicon...)
[08:36:37] ethash ASIC is basically a glorified memory controller
[08:36:39] sech1: tevador said something more is coming (he just did it again)
[08:37:03] yes, some parts of RandomX are not described well
[08:37:10] like dataset access logic
[08:37:37] RandomX looks like progpow for CPU
[08:37:54] yes
[08:38:03] it is designed to reflect CPU
[08:38:34] so any ASIC for it = CPU in essence
[08:39:04] of course there are still some things in regular CPU that can be thrown away for RandomX
[08:40:20] uncore parts are not used, but those will use very little power
[08:40:37] except for memory controller
[08:41:09] I'm just surprised sometimes, ok? let me ask: have you designed or taped out an asic before? isn't it risky to make assumptions about things that are largely unknown?
[08:41:23] I would worry
[08:41:31] that I get something wrong...
[08:41:44] but I also worry like crazy that CNv4 will blow up, where you guys seem to be relaxed
[08:42:06] I didn't want to bring up anything RandomX because CNv4 is such a nailbiter... :)
[08:42:15] how do you guys know you don't have asics in a week or two?
[08:42:38] we don't have experience with ASIC design, but RandomX is simply designed to exactly fit CPU capabilities, which is the best you can do anyways
[08:43:09] similar as ProgPoW did with GPUs
[08:43:14] some people say they want to do asic-resistance only until the vast majority of coins has been issued
[08:43:21] that's at least reasonable
[08:43:43] yeah but progpow totally will not work as advertised :)
[08:44:08] yeah, I've seen that comment about progpow a few times already
[08:44:11] which is no surprise if you know it's just a random sales story to sell a few more GPUs
[08:44:13] RandomX is not permanent, we are expecting to switch to ASIC friendly in a few years if possible
[08:44:18] yes
[08:44:21] that makes sense
[08:44:40] linzhi-sonia: how so? will it break or will it be asic-able with decent performance gains?
[08:44:41] are you happy with CNv4 so far?
[08:45:10] ah, long story. progpow is a masterpiece of deception, let's not get into it here.
[08:45:21] if you know chip marketing it makes more sense
[08:45:24] linzhi-sonia: So far? lol! a bit early to tell, don't you think?
[08:45:35] the diff is coming down
[08:45:41] first few hours looked scary
[08:45:43] I remain skeptical: I only see ASICs being reasonable if they are already as ubiquitous as smartphones
[08:45:46] yes, so far so good
[08:46:01] we kbew the diff would not come down ubtil affter block 75
[08:46:10] yes
[08:46:22] but first few hours it looks like only 5% hashrate left
[08:46:27] looked
[08:46:29] now it's better
[08:46:51] the next worry is: when will "unexplainable" hashrate come back?
[08:47:00] you hope 2-3 months? more?
[08:47:05] so give it another couple of days. will probably overshoot to the downside, and then rise a bit as miners get updated and return
[08:47:22] 3 months minimum turnaround, yes
[08:47:28] nah
[08:47:36] don't underestimate asicmakers :)
[08:47:54] you guys don't get #1 priority on chip fabs
[08:47:56] 3 months = 90 days. do you know what is happening in those 90 days exactly? I'm pretty sure you don't. same thing as before.
[08:48:13] we don't do any secret chips btw
[08:48:21] 3 months assumes they had a complete design ready to go, and added the last minute change in 1 day
[08:48:24] do you know who is behind the hashrate that is now bricked?
[08:48:27] innosilicon?
[08:48:34] hyc: no no, and no. :)
[08:48:44] hyc: have you designed or taped out a chip before?
[08:48:51] yes, many years ago
[08:49:10] then you should know that 90 days is not a fixed number
[08:49:35] sure, but like I said, other makers have greater demand
[08:49:35] especially not if you can prepare, if you just have to modify something, or you have more programmability in the chip than some people assume
[08:50:07] we are chipmakers, we would never dare to do what you guys are doing with CNv4 :) but maybe that just means you are cooler!
[08:50:07] and yes, programmability makes some aspect of turnaround easier
[08:50:10] all fine
[08:50:10] I hope it works!
[08:50:28] do you know who is behind the hashrate that is now bricked?
[08:50:29] inno?
[08:50:41] we suspect so, but have no evidence
[08:50:44] maybe we can try to find them, but we cannot spend too much time on this
[08:50:53] it's probably not so much of a secret
[08:51:01] why should it be, right?
[08:51:10] devs want this cat-and-mouse game? devs get it...
[08:51:35] there was one leak saying it's innosilicon
[08:51:36] so you think 3 months, ok
[08:51:43] inno is cool
[08:51:46] good team
[08:51:49] IP design house
[08:51:54] in Wuhan
[08:52:06] they send their people to conferences with fake biz cards :)
[08:52:19] pretending to be other companies?
[08:52:26] sure
[08:52:28] ha ha
[08:52:39] so when we see them, we look at whatever card they carry and laugh :)
[08:52:52] they are perfectly suited for secret mining games
[08:52:59] they made at most $6 million in 2 months of mining, so I wonder if it was worth it
[08:53:10] yeah. no way to know
[08:53:15] but it's good that you calculate!
[08:53:24] this is all about cost/benefit
[08:53:25] then you also understand - imagine the value of XMR goes up 5x, 10x
[08:53:34] that whole "asic resistance" thing will come down like a house of cards
[08:53:41] I would imagine they sell immediately
[08:53:53] the investor may fully understand the risk
[08:53:57] the buyer
[08:54:13] it's not healthy, but that's another discussion
[08:54:23] so mid-June
[08:54:27] let's see
[08:54:49] I would be susprised if CNv4 ASICs show up at all
[08:54:56] surprised*
[08:54:56] why?
[08:55:05] is only an economic question
[08:55:12] yeah should be interesting. FPGAs will be near their limits as well
[08:55:16] unless XMR goes up a lot
[08:55:19] no, not *only*. it's also a technology question
[08:55:44] you believe CNv4 is "asic resistant"? which feature?
[08:55:53] it's not
[08:55:59] cnv4 = Rabdomx ?
[08:56:03] no
[08:56:07] cnv4=cryptinight/r
[08:56:11] ah
[08:56:18] CNv4 is the one we have now, I think
[08:56:21] since yesterday
[08:56:30] it's plenty enough resistant for current XMR price
[08:56:45] that may be, yes!
[08:56:55] I look at daily payouts. XMR = ca. 100k USD / day
[08:57:03] it can hold until October, but it's not asic resistant
[08:57:23] well, last 24h only 22,442 USD :)
[08:57:32] I think 80 h/s per watt ASICs are possible for CNv4
[08:57:38] linzhi-sonia where do you produce your chips? TSMC?
[08:57:44] I'm cruious how you would expect to build a randomX ASIC that outperforms ARM cores for efficiency, or Intel cores for raw speed
[08:57:48] curious
[08:58:01] yes, tsmc
[08:58:21] Our team did the world's first bitcoin asic, Avalon
[08:58:25] and upcoming 2nd gen Ryzens (64-core EPYC) will be a blast at RandomX
[08:58:28] designed and manufactured
[08:58:53] still being marketed?
[08:59:03] linzhi-sonia: do you understand what xmr wants to achieve, community-wise?
[08:59:14] Avalon? as part of Canaan Creative, yes I think so.
[08:59:25] there's not much interesting oing on in SHA256
[08:59:29] Inge-: I would think so, but please speak
[08:59:32] hyc: yes
[09:00:28] linzhi-sonia: i am curious to hear your thoughts. I am fairly new to this space myself...
[09:00:51] oh
[09:00:56] we are grandpas, and grandmas
[09:01:36] yet I have no problem understanding why ASICS are currently reviled.
[09:01:48] xmr's main differentiators to, let's say btc, are anonymity and fungibility
[09:01:58] I find the client terribly slow btw
[09:02:21] and I think the asic-forking since last may is wrong, doesn't create value and doesn't help with the project objectives
[09:02:25] which "the client" ?
[09:02:52] Monero GUI client maybe
[09:03:12] MacOS, yes
[09:03:28] What exactly is slow?
[09:03:30] linzhi-sonia: I run my own node, and use the CLI and Monerujo. Have not had issues.
[09:03:49] staying in sync
[09:03:49] linzhi-sonia: decentralization is also a key principle
[09:03:56] one that Bitcoin has failed to maintain
[09:04:39] hmm
[09:05:00] looks fairly decentralized to me. decentralization is the result of 3 goals imo: resilient, trustless, permissionless
[09:05:28] don't ask a hardware maker about physical decentralization. that's too ideological. we focus on logical decentralization.
[09:06:11] physical decentralization is important. with bulk of bitnoin mining centered on Chinese hydroelectric dams
[09:06:19] have you thought about including block data in the PoW?
[09:06:41] yes, of course.
[09:07:39] is that already in an algo?
[09:08:10] hyc: about "centered on chinese hydro" - what is your source? the best paper I know is this: https://coinshares.co.uk/wp-content/uploads/2018/11/Mining-Whitepaper-Final.pdf
[09:09:01] linzhi-sonia: do you mine on your ASICs before you sell them?
[09:09:13] besides testing of course
[09:09:45] that paper puts Chinese btc miners at 60% max
[09:10:05] tevador: I think everybody learned that that is not healthy long-term!
[09:10:16] because it gives the chipmaker a cost advantage over its own customers
[09:10:33] and cost advantage leads to centralization (physical and logical)
[09:10:51] you guys should know who finances progpow and why :)
[09:11:05] but let's not get into this, ha ha. want to keep the channel civilized. right OhGodAGirl ? :)
[09:11:34] tevador: so the answer is no! 100% and definitely no
[09:11:54] that "self-mining" disease was one of the problems we have now with asics, and their bad reputation (rightfully so)
[09:13:08] I plan to write a nice short 2-page paper or so on our chip design process. maybe it's interesting to some people here.
[09:13:15] basically the 5 steps I mentioned before, from math to physical
[09:13:32] linzhi-sonia: the paper you linked puts 48% of bitcoin mining in Sichuan. the total in China is much more than 60%
[09:13:38] need to run it by a few people to fix bugs, will post it here when published
[09:14:06] hyc: ok! I am just sharing the "best" document I know today. it definitely may be wrong and there may be a better one now.
[09:14:18] hyc: if you see some reports, please share
[09:14:51] hey I am really curious about this: where is a PoW algo that puts block data into the PoW?
[09:15:02] the previous paper I read is from here http://hackingdistributed.com/2018/01/15/decentralization-bitcoin-ethereum/
[09:15:38] hyc: you said that already exists? (block data in PoW)
[09:15:45] it would make verification harder
[09:15:49] linzhi-sonia: https://the-eye.eu/public/Books/campdivision.com/PDF/Computers%20General/Privacy/bitcoin/meh/hashimoto.pdf
[09:15:51] but for chips it would be interesting
[09:15:52] we discussed the possibility about a year ago https://www.reddit.com/Monero/comments/8bshrx/what_we_need_to_know_about_proof_of_work_pow/
[09:16:05] oh good links! thanks! need to read...
[09:16:06] I think that paper by dryja was original
[09:17:53] since we have a nice flow - second question I'm very curious about: has anyone thought about in-protocol rewards for other functions?
[09:18:55] we've discussed micropayments for wallets to use remote nodes
[09:18:55] you know there is a lot of work in other coins about STARK provers, zero-knowledge, etc. many of those things very compute intense, or need to be outsourced to a service (zether). For chipmakers, in-protocol rewards create an economic incentive to accelerate those things.
[09:19:50] whenever there is an in-protocol reward, you may get the power of ASICs doing something you actually want to happen
[09:19:52] it would be nice if there was some economic reward for running a fullnode, but no one has come up with much more than that afaik
[09:19:54] instead of fighting them off
[09:20:29] you need to use asics, not fight them. that's an obvious thing to say for an asicmaker...
[09:20:41] in-protocol rewards can be very powerful
[09:20:50] like I said before - unless the ASICs are so useful they're embedded in every smartphone, I dont see them being a positive for decentralization
[09:21:17] if they're a separate product, the average consumer is not going to buy them
[09:21:20] now I was talking about speedup of verifying, signing, proving, etc.
[09:21:23] they won't even know what they are
[09:22:07] if anybody wants to talk about or design in-protocol rewards, please come talk to us
[09:22:08] the average consumer also doesn't use general purpose hardware to secure blockchains either
[09:22:14] not just for PoW, in fact *NOT* for PoW
[09:22:32] it requires sw/hw co-design
[09:23:10] we are in long-term discussions/collaboration over this with Ethereum, Bitcoin Cash. just talk right now.
[09:23:16] this was recently published though suggesting more uptake though I guess https://btcmanager.com/college-students-are-the-second-biggest-miners-of-cryptocurrency/
[09:23:29] I find it pretty hard to believe their numbers
[09:24:03] well
[09:24:09] sorry, original article: https://www.pcmag.com/news/366952/college-kids-are-using-campus-electricity-to-mine-crypto
[09:24:11] just talk, no? rumors
[09:24:18] college students are already more educated than the average consumer
[09:24:29] we are not seeing many such customers anymore
[09:24:30] it's data from cisco monitoring network traffic
[09:24:33] and they're always looking for free money
[09:24:48] of course anyone with "free" electricity is inclined to do it
[09:24:57] but look at the rates, cannot make much money
[09:26:06] Ethereum is a bloated collection of bugs wrapped in a UI. I suppose they need all the help they can get
[09:26:29] Bitcoin Cash ... just another get rich quick scheme
[09:26:38] hmm :)
[09:26:51] I'll give it back to you, ok? ha ha. arrogance comes before the fall...
[09:27:17] maye we should have a little fun with CNv4 mining :)
[09:27:25] ;)
[09:27:38] come on. anyone who has watched their track record... $75M lost in ETH at DAO hack
[09:27:50] every smart contract that comes along is just waiting for another hack
[09:27:58] I just wanted to throw out the "in-protocol reward" thing, maybe someone sees the idea and wants to cowork. maybe not. maybe it's a stupid idea.
[09:29:18] linzhi-sonia: any thoughts on CN-GPU?
[09:29:55] CN-GPU has one positive aspect - it wastes chip area to implement all 18 hash algorithms
[09:30:19] you will always hear roughly the same feedback from me:
[09:30:52] "This algorithm very different, it heavy use floating point operations to hurt FPGAs and general purpose CPUs"
[09:30:56] the problem is, if it's profitable for people to buy ASIC miners and mine, it's always more profitable for the manufacturer to not sell and mine themselves
[09:31:02] "hurt"
[09:31:07] what is the point of this?
[09:31:15] it totally doesn't work
[09:31:24] you are hurting noone, just demonstrating lack of ability to think
[09:31:41] what is better: algo designed for chip, or chip designed for algo?
[09:31:43] fireice does it on daily basis, CN-GPU is a joke
[09:31:53] tevador: that's not really true, especially in a market with such large price fluctuations as cryptocurrency
[09:32:12] it's far less risky to sell miners than mine with them and pray that price doesn't crash for next six months
[09:32:14] I think it's great that crypto has a nice group of asicmakers now, hw & sw will cowork well
[09:32:36] jwinterm yes, that's why they premine them and sell after
[09:32:41] PoW is about being thermodynamically and cryptographically provable
[09:32:45] premining with them is taking on that risk
[09:32:49] not "fork when we think there are asics"
[09:32:51] business is about risk minimization
[09:32:54] that's just fear-driven
[09:33:05] Inge-: that's roughly the feedback
[09:33:24] I'm not saying it hasn't happened, but I think it's not so simple as saying "it always happens"
[09:34:00] jwinterm: it has certainly happened on BTC. and also on XMR.
[09:34:19] ironically, please think about it: these kinds of algos indeed prove the limits of the chips they were designed for. but they don't prove that you cannot implement the same algo differently! cannot!
[09:34:26] Risk minimization is not starting a business at all.
[09:34:34] proof-of-gpu-limit. proof-of-cpu-limit.
[09:34:37] imagine you have a money printing machine, would you sell it?
[09:34:39] proves nothing for an ASIC :)
[09:35:05] linzhi-sonia: thanks. I dont think anyone believes you can't make a more efficient cn-gpu asic than a gpu - but that it would not be orders of magnitude faster...
[09:35:24] ok
[09:35:44] like I say. these algos are, that's really ironic, designed to prove the limitatios of a particular chip in mind of the designer
[09:35:50] exactly the wrong way round :)
[09:36:16] like the cache size in RandomX :)
[09:36:18] beautiful
[09:36:29] someone looked at GPU designs
[09:37:31] linzhi-sonia can you elaborate? Cache size in RandomX was selected to fit CPU cache
[09:37:52] yes
[09:38:03] too large for GPU
[09:38:11] as I said, we are designing the algorithm to exactly fit CPU capabilities, I do not claim an ASIC cannot be more efficient
[09:38:16] ok!
[09:38:29] when will you do the audit?
[09:38:35] will the results be published in a document or so?
[09:38:37] I claim that single-chip ASIC is not viable, though
[09:39:06] you guys are brave, noone disputes that. 3 anti-asic hardforks now!
[09:39:18] 4th one coming
[09:39:31] 3 forks were done not only for this
[09:39:38] they had scheduled updates in the first place
[09:48:10] Monero is the #1 anti-asic fighter
[09:48:25] Monero is #1 for a lot of reasons ;)
[09:48:40] It's the coin with the most hycs.
[09:48:55] mooooo
[09:59:06] sneaky integer overflow, bug squished
[10:38:00] p0nziph0ne ([email protected]/vpn/privateinternetaccess/p0nziph0ne) has joined #monero-pow
[11:10:53] The convo here is wild
[11:12:29] it's like geo-politics at the intersection of software and hardware manufacturing for thermoeconomic value.
[11:13:05] ..and on a Sunday.
[11:15:43] midipoet: hw and sw should work together and stop silly games to devalue each other. to outsiders this is totally not attractive.
[11:16:07] I appreciate the positive energy here to try to listen, learn, understand.
[11:16:10] that's a start
[11:16:48] <-- p0nziph0ne ([email protected]/vpn/privateinternetaccess/p0nziph0ne) has quit (Quit: Leaving)
[11:16:54] we won't do silly mining against xmr "community" wishes, but not because we couldn'd do it, but because it's the wrong direction in the long run, for both sides
[11:18:57] linzhi-sonia: I agree to some extent. Though, in reality, there will always be divergence between social worlds. Not every body has the same vision of the future. Reaching societal consensus on reality tomorrow is not always easy
[11:20:25] absolutely. especially at a time when there is so much profit to be made from divisiveness.
[11:20:37] someone will want to make that profit, for sure
[11:24:32] Yes. Money distorts.
[11:24:47] Or wealth...one of the two
[11:26:35] Too much physical money will distort rays of light passing close to it indeed.

Mining for Profitability - Horizen (formerly ZenCash) Thanks Early GPU Miners

Mining for Profitability - Horizen (formerly ZenCash) Thanks Early GPU Miners
Thank you for inviting Horizen to the GPU mining AMA!
ZEN had a great run of GPU mining that lasted well over a year, and brought lots of value to the early Zclassic miners. It is mined using Equihash protocol, and there have been ASIC miners available for the algorithm since about June of 2018. GPU mining is not really profitable for Horizen at this point in time.
We’ve got a lot of miners in the Horizen community, and many GPU miners also buy ASIC miners. Happy to talk about algorithm changes, security, and any other aspect of mining in the questions below. There are also links to the Horizen website, blog post, etc. below.
So, if I’m not here to ask you to mine, hold, and love ZEN, what can I offer? Notes on some of the lessons I’ve learned about maximizing mining profitability. An update on Horizen - there is life after moving on from GPU mining. As well as answering your questions during the next 7 days.

Mining for Profitability - Horizen (formerly ZenCash) Thanks Early GPU Miners

Author: Rolf Versluis - co-founder of Horizen

In GPU mining, just like in many of the activities involved with Bitcoin and cryptocurrencies, there is both a cycle and a progression. The Bitcoin price cycle is fairly steady, and by creating a personal handbook of actions to take during the cycle, GPU miners can maximize their profitability.
Maximizing profitability isn't the only aspect of GPU mining that is important, of course, but it is helpful to be able to invest in new hardware, and be able to have enough time to spend on building and maintaining the GPU miners. If it was a constant process that also involved losing money, then it wouldn't be as much fun.

Technology Progression

For a given mining algorithm, there is definitely a technology progression. We can look back on the technology that was used to mine Bitcoin and see how it first started off as Central Processing Unit (CPU) mining, then it moved to Graphical Processing Unit (GPU) mining, then Field Programmable Gate Array (FPGA), and then Application Specific Integrated Circuit (ASIC).
Throughout this evolution we have witnessed a variety of unsavory business practices that unfortunately still happen on occasion, like ASIC Miner manufacturers taking pre-orders 6 months in advance, GPU manufacturers creating commercial cards for large farms that are difficult for retail customers to secure and ASIC Miner manufacturers mining on gear for months before making it available for sale.
When a new crypto-currency is created, in many cases a new mining algorithm is created also. This is important, because if an existing algorithm was used, the coin would be open to a 51% attack from day one, and may not even be able to build a valid blockchain.
Because there's such a focus on profitable software, developers for GPU mining applications are usually able to write a mining application fairly rapidly, then iterate it to the limit of current GPU technology. If it looks like a promising new cryptocurrency, FPGA stream developers and ASIC Hardware Developers start working on their designs at the same time.
The people who create the hashing algorithms run by the miners are usually not very familiar with the design capabilities of Hardware manufacturers. Building application-specific semiconductors is an industry that's almost 60 years old now, and FPGA’s have been around for almost 35 years. This is an industry that has very experienced engineers using advanced design and modeling tools.
Promising cryptocurrencies are usually ones that are deploying new technology, or going after a big market, and who have at least a team of talented software developers. In the best case, the project has a full-stack business team involving development, project management, systems administration, marketing, sales, and leadership. This is the type of project that attracts early investment from the market, which will drive the price of the coin up significantly in the first year.
For any cryptocurrency that's a worthwhile investment of time, money, and electricity for the hashing, there will be a ASIC miners developed for it. Instead of fighting this technology progression, GPU miners may be better off recognizing it as inevitable, and taking advantage of the cryptocurrency cycle to maximize GPU mining profitability instead.

Cryptocurrency Price Cycle

For quality crypto projects, in addition to the one-way technology progression of CPU -> GPU -> FPGA -> ASIC, there is an upward price progression. More importantly, there is a cryptocurrency price cycle that oscillates around an overall upgrade price progression. Plotted against time, a cycle with an upward progressions looks like a sine wave with an ever increasing average value, which is what we see so far with the Bitcoin price.

Cryptocurrency price cycle and progression for miners
This means mining promising new cryptocurrencies with GPU miners, holding them as the price rises, and being ready to sell a significant portion in the first year. Just about every cryptocurrency is going to have a sharp price rise at some point, whether through institutional investor interest or by being the target of a pump-and-dump operation. It’s especially likely in the first year, while the supply is low and there is not much trading volume or liquidity on exchanges.
Miners need to operate in the world of government money, as well as cryptocurrency. The people who run mining businesses at some point have to start selling their mining proceeds to pay the bills, and to buy new equipment as the existing equipment becomes obsolete. Working to maximize profitability means more than just mining new cryptocurrencies, it also means learning when to sell and how to manage money.

Managing Cash for Miners

The worst thing that can happen to a business is to run out of cash. When that happens, the business usually shuts down and goes into bankruptcy. Sometimes an investor comes in and picks up the pieces, but at the point the former owners become employees.
There are two sides to managing cash - one is earning it, the other is spending it, and the cryptocurrency price cycle can tell the GPU miner when it is the best time to do certain things. A market top and bottom is easy to recognize in hindsight, and harder to see when in the middle of it. Even if a miner is able to recognize the tops and bottoms, it is difficult to act when there is so much hype and positivity at the top of the cycle, and so much gloom and doom at the bottom.
A decent rule of thumb for the last few cycles appears to be that at the top and bottom of the cycle BTC is 10x as expensive compared to USD as the last cycle. Newer crypto projects tend to have bigger price swings than Bitcoin, and during the rising of the pricing cycle there is the possibility that an altcoin will have a rise to 100x its starting price.
Taking profits from selling altcoins during the rise is important, but so is maintaining a reserve. In order to catch a 100x move, it may be worth the risk to put some of the altcoin on an exchange and set a very high limit order. For the larger cryptocurrencies like Bitcoin it is important to set trailing sell stops on the way up, and to not buy back in for at least a month if a sell stop gets triggered. Being able to read price charts, see support and resistance areas for price, and knowing how to set sell orders are an important part of mining profitability.

Actions to Take During the Cycle

As the cycle starts to rise from the bottom, this is a good time to buy mining hardware - it will be inexpensive. Also to mine and buy altcoins, which are usually the first to see a price rise, and will have larger price increases than Bitcoin.
On the rise of the cycle, this is a good time to see which altcoins are doing well from a project fundamentals standpoint, and which ones look like they are undergoing accumulation from investors.
Halfway through the rise of the cycle is the time to start selling altcoins for the larger project cryptos like Bitcoin. Miners will miss some of the profit at the top of the cycle, but will not run out of cash by doing this. This is also the time to stop buying mining hardware. Don’t worry, you’ll be able to pick up that same hardware used for a fraction of the price at the next bottom.
As the price nears the top of the cycle, sell enough Bitcoin and other cryptocurrencies to meet the following projected costs:
  • Mining electricity costs for the next 12 months
  • Planned investment into new miners for the next cycle
  • Additional funds needed for things like supporting a family or buying a Lambo
  • Taxes on all the capital gains from the sale of cryptocurrencies
It may be worth selling 70-90% of crypto holdings, maintaining a reserve in case there is second upward move caused by government bankruptcies. But selling a large part of the crypto is helpful to maintaining profitability and having enough cash reserves to make it through the bottom part of the next cycle.
As the cycle has peaked and starts to decline, this is a good time to start investing in mining facilities and other infrastructure, brush up on trading skills, count your winnings, and take some vacation.
At the bottom of the cycle, it is time to start buying both used and new mining equipment. The bottom can be hard to recognize.
If you can continue to mine all the way through bottom part of the cryptocurrency pricing cycle, paying with the funds sold near the top, you will have a profitable and enjoyable cryptocurrency mining business. Any cryptocurrency you are able to hold onto will benefit from the price progression in the next higher cycle phase.

An Update on Horizen - formerly ZenCash

The team at Horizen recognizes the important part that GPU miners played in the early success of Zclassic and ZenCash, and there is always a welcoming attitude to any of ZEN miners, past and present. About 1 year after ZenCash launched, ASIC miners became available for the Equihash algorithm. Looking at a chart of mining difficulty over time shows when it was time for GPU miners to move to mining other cryptocurrencies.

Horizen Historical Block Difficulty Graph
Looking at the hashrate chart, it is straightforward to see that ASIC miners were deployed starting June 2018. It appears that there was a jump in mining hashrate in October of 2017. This may have been larger GPU farms switching over to mine Horizen, FPGA’s on the network, or early version of Equihash ASIC miners that were kept private.
The team understands the importance of the cryptocurrency price cycle as it affects the funds from the Horizen treasury and the investments that can be made. 20% of each block mined is sent to the Horizen non-profit foundation for use to improve the project. Just like miners have to manage money, the team has to decide whether to spend funds when the price is high or convert it to another form in preparation for the bottom part of the cycle.
During the rise and upper part of the last price cycle Horizen was working hard to maximize the value of the project through many different ways, including spending on research and development, project management, marketing, business development with exchanges and merchants, and working to create adoption in all the countries of the world.
During the lower half of the cycle Horizen has reduced the team to the essentials, and worked to build a base of users, relationships with investors, exchanges, and merchants, and continue to develop the higher priority software projects. Lower priority software development, going to trade shows, and paying for business partnerships like exchanges and applications have all been completely stopped.
Miners are still a very important part of the Horizen ecosystem, earning 60% of the block reward. 20% goes to node operators, with 20% to the foundation. In the summer of 2018 the consensus algorithm was modified slightly to make it much more difficult for any group of miners to perform a 51% attack on Horizen. This has so far proven effective.
The team is strong, we provide monthly updates on a YouTube live stream on the first Wednesday of each month where all questions asked during the stream are addressed, and our marketing team works to develop awareness of Horizen worldwide. New wallet software was released recently, and it is the foundation application for people to use and manage their ZEN going forward.
Horizen is a Proof of Work cryptocurrency, and there is no plan to change that by the current development team. If there is a security or centralization concern, there may be change to the algorithm, but that appears unlikely at this time, as the hidden chain mining penalty looks like it is effective in stopping 51% attacks.
During 2019 and 2020 the Horizen team plans to release many new software updates:
  • Sidechains modification to main software
  • Sidechain Software Development Kit
  • Governance and Treasury application running on a sidechain
  • Node tracking and payments running on a sidechain
  • Conversion from blockchain to a Proof of Work BlockDAG using Equihash mining algorithm
After these updates are working well, the team will work to transition Horizen over to a governance model where major decisions and the allocation of treasury funds are done through a form of democratic voting. At this point all the software developed by Horizen is expected to be open source.
When the governance is transitioned, the project should be as decentralized as possible. The goal of decentralization is to enable resilience and preventing the capture of the project by regulators, government, criminal organizations, large corporations, or a small group of individuals.
Everyone involved with Horizen can be proud of what we have accomplished together so far. Miners who were there for the early mining and growth of the project played a large part in securing the network, evangelizing to new community members, and helping to create liquidity on new exchanges. Miners are still a very important part of the project and community. Together we can look forward to achieving many new goals in the future.

Vertcoin Mining AMA

What is Vertcoin?

Vertcoin was created in 2014. It is a direct hedge against long term mining consensus centralization on the Bitcoin mining network. Vertcoin achieves its mining consensus solely through Graphics Cards as they are the most abundant / widely available consensus devices that produce a reasonable amount of hashrate. This is done using a mining algorithm that deliberately geared against devices like ASICs, FPGAs and CPUs (due to botnets) making them extremely inefficient. Consensus distribution over time is the most important aspect of a blockchain and should not be taken lightly. It is critical that you understand what blockchain specifications mean/do to fully understand Vertcoin.

Mining Vertcoin

When users of our network send each other Vertcoin, their transactions are secured by a process called mining. Miners will compose a so-called block out of the pending transactions, and need to perform a large number of computations called hashes in order to produce the Proof-of-Work. With this Proof-of-Work, the block is accepted by the network and the transactions in it become confirmed.
Mining is essentially a race. Whoever finds a valid Proof-of-Work and gets the block propagated over more than half of the Vertcoin network first, wins this race and is allowed to reward themselves with the block reward. The block reward is how new Vertcoin come in circulation. This block reward started at 50 VTC when Vertcoin was launched, and halves every four years. The current block reward is 25 VTC.

Why Does Vertcoin Use GPUs Then?

ASIC’s (Manufactuer Monopoly)
If mining were just a spade sure, use the most powerful equipment which would be an ASIC. The problem is ASICs are not widely available, and just happen to be controlled by a monopoly in China.
So, you want the most widely available tool that produces a fair amount of hashrate, which currently manifests itself as a Graphics Card.
CPUs would be great too but unfortunately there are viruses that take over hundreds of thousands of computers called Botnets (they’re almost as bad as ASICs).

Mining In Pools

Because mining is a race, it’s difficult for an individual miner to acquire enough computational power to win this race solo. Therefore there’s a concept called pool-mining. With pool-mining, miners cooperate in finding the correct Proof-of-Work for the block, and share the block reward based on the work contributed. The amount of work contributed is measured in so-called shares. Finding the Proof-of-Work for a share is much easier than finding it for a block, and when the cooperating miners find the Proof-of-Work for the block, they distribute the reward based on the number of shares each miner found. Vertcoin always recommends using P2Pool to keep mining as decentralized as possible.
How Do I Get Started?
If you want to get started mining, check out the Mine Vertcoin page.

Vertcoin just forked to Lyra2REv3 and we are currently working on Verthash

Verthash is and was under development before we decided to hard fork to Lyra2REv3. While Verthash would’ve resulted in the same effect for ASICs (making them useless for mining Vertcoin), the timeline was incompatible with the desire to get rid of ASICs quickly. Verthash is still under development and tries to address the outsourcability problem.
Verthash is an I/O bound algorithm that uses the blockchain data as input to the hashing algorithm. It therefore requires miners to have all the blockchain data available to them, which is currently about 4 GB of data. By making this mining data mandatory, it will become harder for auto profit switching miners — like the ones that rent out their GPU to Nicehash — because they will need to keep a full node running while mining other algorithms for the moment Verthash becomes more profitable — the data needs to be available immediately since updating it can take a while.
Over the past month, we have successfully developed a first implementation of Verthash in the Vertcoin Core code base. Within the development team we have run a few nodes on Testnet to test the functionality — and everything seems to work properly. The next step is to build out the GPU miners for AMD and Nvidia. This is a NOETA at the moment, since we’re waiting on GPU developers which are in high demand. Once the miners are ready, we’ll be releasing the Vertcoin 0.15 beta that hardforks the testnet together with the miners for the community to have a testrun. Given the structural difference between Lyra2RE and Verthash, we’ll have to run the testnet for a longer period than we did with the Lyra2REv3 hard fork. We’ll have to make sure the system is reliable before hardforking our mainnet. So the timeline will be longer than with the Lyra2REv3 hard fork.
Some people in the community have voiced concerns about the fact that Verthash development is not being done “out in the open”, i.e.: the code commits are not visible on Github. The main two reasons for us to keep our cards to our chest at this stage are: (1) only when the entire system including miners has been coded up can we be sure the system works, we don’t want to release preliminary stuff that doesn’t work or isn’t secure. Also (2) we don’t want to give hardware manufacturers or mining outsourcing platforms a head start on trying to defeat the mechanisms we’ve put in place.

Electroneum Fork 324500

Source: https://www.facebook.com/electroneum/posts/2030562537205714
Hi Everyone!
ALL ELECTRONEUM NODE OWNERS MUST UPDATE THEIR SOFTWARE BY BLOCK 324500 (approx. 36 hours from now – this is an URGENT UPDATE – PLEASE SHARE THIS INFORMATION)
We have an urgent software update below for anyone who runs a full Electroneum Node. If you don’t know what a node is , don’t worry! You won’t need to do anything.
We also have a VERY exciting update about an upcoming listing on a top 10 exchange.
How will I mine Electroneum after this update?
Instant Payment vendor API is open for BETA applicants.How can ETN change the world?
Please note that nothing in this message refers to MOBILE MINING – we are referring to the underlying blockchain miners.
Urgent Electroneum Node / RPC / Command Line Wallet Update
ALL ELECTRONEUM NODE OWNERS MUST UPDATE THEIR SOFTWARE BY BLOCK 324500 (approx. 36 hours from now – this is an URGENT UPDATE – PLEASE SHARE THIS INFORMATION)
https://github.com/electron…/electroneum/releases/…/v2.1.0.0
It’s only been a few short days since I made a video and said “our fork went well! We’re ready for 20m Users!”.
The fork was a great success, from a technical standpoint. Unfortunately, we never got back the number of GPU miners that are needed to ensure our network runs smoothly and has stable block emission. A new phenomenon has emerged where a number of users are mining Electroneum in waves. They come on and then leave after a few hours in a coordinated manner to mine ETN in a completely selfish way. We can’t blame people for maximizing their profit, but we have not built up the amount of “hashing power” that is required to make this impossible and create the stability we need in the network.
This has left us at risk. As such, we have to take urgent action to stabilise our network and protect the Electroneum community.
Coinbene Listing Electroneum & our network stability
We have formally agreed and signed contracts to be listed in July on the AWESOME, top 10, cryptocurrency exchange https://Coinbene.com & https://Coinbene.com.br
Coinbene have 1.5m active users and are a GREAT fit for Electroneum. Their primary markets are Latin America and Asia – which fits perfectly with Electroneum’s customer base. They have seen enormous growth over the last few months and have been very positive about the Electroneum Project.
Whilst this is great news, we will need much more hashing power to ensure we have network stability for our listing on this exchange, so we’ve taken the decision that we can’t wait any longer for GPU miners to return to us and we must run an urgent software update to re-introduce ASIC mining to Electroneum.
This is a very positive move for Electroneum. A great deal of Bitcoin’s trust and appeal is from the enormous hashing power and distribution of miners on the network. Bitcoin & LiteCoin have embraced ASICs and we feel that it is the right thing for Electroneum to do the same.
ASICS are becoming more prevalent, they cost considerably less to run than a GPU rig and use a fraction of the electricity. We are going to encourage more ASIC ownership and take our hashing rate up to (and beyond) the enormous levels of hashing power that we had before the May fork.
There is a further development. The first generation of hardware called an FPGA miner is arriving during 2018 and they make ANTI-ASIC capabilities a thing of the past, as they circumvent the slow delivery time of new ASICs by being re-programmable. If we are ready to embrace these rather than fight them, our network hashing power is increased further and our network stability and security is further enhanced.
Because ASICS run cooler, quieter and use a fraction of GPU rig power, they are suitable for MORE people to run in their homes. If you are interested, a search of “Cryptonight ASIC miner” in Google or Ebay will find the equipment needed to mine Electroneum. You will need to be reasonably technical to achieve this!
Having a stable network is absolutely key to both delivering mass adoption and to ensure we have a great relationship with the great exchanges that we’re already listed with, and to encourage more of the larger exchanges to see Electroneum as a coin that they want on board.
How will I mine Electroneum after this update?
If you are a mobile miner – nothing changes. If you are a GPU or ASIC miner then you’ll need to connect to an Electroneum pool but it is important to note that you will need to change your ALGORITHM. You MUST use the algorithm “Cryptonight” and NOT “Electroneum” or “CryptonightV7”. This will ensure your device works after the update. We will communicate this to all pools, but if you are a member of a mining pool – PLEASE LET THE ADMINS KNOW ABOUT THIS CRITICAL UPDATE. They must update their pool node by block 324500, which is only around 36 hours away.
Instant Payment vendor API is open for BETA applicants
Instant Cryptocurrency Payments via smart phone has always been a critical part of what Electroneum required to achieve mass market adoption. It’s never been done, but 9 short months after our ICO we are excited to announce that we have opened to the doors to vendors who would like to accept payment via Electroneum. The application is to be part of the BETA rollout of instant payment, but will operate on the live blockchain with real ETN!
If you run a business or know someone who does – why not recommend they apply to accept ETN. The Press and Marketing opportunities for the first, in any sector, to accept cryptocurrency are huge! Be part of the instant payment API BETA program by completing this form:
https://docs.google.com/…/1FAIpQLSfKTwWT7W4ltmApZO…/viewform
How can ETN change the world?
Instant payment does far more than allow people to pay for their coffee with crypto instead of their VISA card.
If you’d like to know more about Electroneum’s future I suggest you read a fantastic article that describes its coming role in the world, by fellow director Chris Gorman OBE (Officer of the British Empire – awarded by the Queen of England!): https://www.linkedin.com/…/how-cryptocurrency-enable-financ…
Electroneum has one of the largest of all cryptocurrency communities and it is made up of passionate and amazing people. With your support and world changing things we have coming out over the next few weeks, we can use this update to make our blockchain foundation secure and lead the world in mobile cryptocurrency.
I'm sure you agree that we've been through some challenging times which our team have always dealt with and learned from. The strength and support from our community and many of our goals becoming a reality combined with this blockchain update will give us the perfect foundation to deliver the Electroneum vision that we all share.
Thanks for taking the time to read this long message.
Have a great day everyone,

Mining ERC-918 Tokens (0xBitcoin)

GENERAL INFORMATION

0xBitcoin (0xBTC) is the first mineable ERC20 token on Ethereum. It uses mining for distribution, unlike all previous ERC20 tokens which were assigned to the contract deployer upon creation. 0xBTC is the first implementation of the EIP918 mineable token standard (https://eips.ethereum.org/EIPS/eip-918), which opened up the possibility of a whole new class of mineable assets on Ethereum. Without any ICO, airdrop, pre-mine, or founder’s reward, 0xBitcoin is arguably the most decentralized asset in the Ethereum ecosystem, including even Ether (ETH), which had a large ICO.
The goal of 0xBitcoin is to be looked at as a currency and store of value asset on Ethereum. Its 21 million token hard cap and predictable issuance give it scarcity and transparency in terms of monetary policy, both things that Ether lacks. 0xBitcoin has certain advantages over PoW based currencies, such as compatibility with smart contracts and decentralized exchanges. In addition, 0xBTC cannot be 51% attacked (without attacking Ethereum), is immune from the “death spiral”, and will receive the benefits of scaling and other improvements to the Ethereum network.

GETTING 0xBITCOIN TOKENS

0xBitcoin can be mined using typical PC hardware, traded on exchanges (either decentralized or centralized) or purchased from specific sites/contracts.

-Mined using PC hardware

-Traded on exchanges such as


MINING IN A NUTSHELL

0xBitcoin is a Smart Contract on the Ethereum network, and the concept of Token Mining is patterned after Bitcoin's distribution. Rather than solving 'blocks', work is issued by the contract, which also maintains a Difficulty which goes up or down depending on how often a Reward is issued. Miners can put their hardware to work to claim these rewards, in concert with specialized software, working either by themselves or together as a Pool. The total lifetime supply of 0xBitcoin is 21,000,000 tokens and rewards will repeatedly halve over time.
The 0xBitcoin contract was deployed by Infernal_Toast at Ethereum address: 0xb6ed7644c69416d67b522e20bc294a9a9b405b31
0xBitcoin's smart contract, running on the Ethereum network, maintains a changing "Challenge" (that is generated from the previous Ethereum block hash) and an adjusting Difficulty Target. Like traditional mining, the miners use the SoliditySHA3 algorithm to solve for a Nonce value that, when hashed alongside the current Challenge and their Minting Ethereum Address, is less-than-or-equal-to the current Difficulty Target. Once a miner finds a solution that satisfies the requirements, they can submit it into the contract (calling the Mint() function). This is most often done through a mining pool. The Ethereum address that submits a valid solution first is sent the 50 0xBTC Reward.
(In the case of Pools, valid solutions that do not satisfy the full difficulty specified by the 0xBitcoin contract, but that DO satisfy the Pool's specified Minimum Share Difficulty, get a 'share'. When one of the Miners on that Pool finds a "Full" solution, the number of shares each miner's address has submitted is used to calculate how much of the 50 0xBTC reward they will get. After a Reward is issued, the Challenge changes.
A Retarget happens every 1024 rewards. In short, the Contract tries to target an Average Reward Time of about 60 times the Ethereum block time. So (at the time of this writing):
~13.9 seconds \* 60 = 13.9 minutes
If the average Reward Time is longer than that, the difficulty will decrease. If it's shorter, it will increase. How much longer or shorter it was affects the magnitude with which the difficulty will rise/drop, to a maximum of 50%. * Click Here to visit the stats page~ (https://0x1d00ffff.github.io/0xBTC-Stats) to see recent stats and block times, feel free to ask questions about it if you need help understanding it.

MINING HARDWARE

Presently, 0xBitcoin and "Alt Tokens" can be mined on GPUs, CPUs, IGPs (on-CPU graphics) and certain FPGAs. The most recommended hardware is nVidia graphics cards for their efficiency, ubiquity and relatively low cost. As general rules, the more cores and the higher core frequency (clock) you can get, the more Tokens you will earn!

Best $100-$300 FPGA development board in 2018?

Hello, I’ve been trying to decide on a FPGA development board, and have only been able to find posts and Reddit threads from 4-5 years ago. So I wanted to start a new thread and ask about the best “mid-range” FGPA development board in 2018. (Price range $100-$300.)
I started with this Quora answer about FPGA boards, from 2013. The Altera DE1 sounded good. Then I looked through the Terasic DE boards.
Then I found this Reddit thread from 2014, asking about the DE1-SoC vs the Cyclone V GX Starter Kit: https://www.reddit.com/FPGA/comments/1xsk6w/cyclone_v_gx_starter_kit_vs_de1soc_board/‬ (I was also leaning towards the DE1-SoC.)
Anyway, I thought I better ask here, because there are probably some new things to be aware of in 2018.
I’m completely new to FPGAs and VHDL, but I have experience with electronics/microcontrollers/programming. My goal is to start with some basic soft-core processors. I want to get some C / Rust programs compiling and running on my own CPU designs. I also want to play around with different instruction sets, and maybe start experimenting with asynchronous circuits (e.g. clock-less CPUs)
Also I don’t know if this is possible, but I’d like to experiment with ternary computing, or work with analog signals instead of purely digital logic. EDIT: I just realized that you would call those FPAAs, i.e. “analog” instead of “gate”. Would be cool if there was a dev board that also had an FPAA, but no problem if not.
EDIT 2: I also realized why "analog signals on an FPGA" doesn't make any sense, because of how LUTs work. They emulate boolean logic with a lookup table, and the table can only store 0s and 1s. So there's no way to emulate a transistor in an intermediate state. I'll just have play around with some transistors on a breadboard.
UPDATE: I've put together a table with some of the best options:
Board Maker Chip LUTs Price SoC? Features
icoBoard Lattice iCE40-HX8K 7,680 $100 Sort of A very simple FPGA development board that plugs into a Raspberry Pi, so you have a "backup" hard-core CPU that can control networking, etc. Supports a huge range of pmod accessories. You can write a program/circuit so that the Raspberry Pi CPU and the FPGA work together, similar to a SoC. Proprietary bitstream is fully reverse engineered and supported by Project IceStorm, and there is an open-source toolchain that can compile your hardware design to bitstream. Has everything you need to start experimenting with FPGAs.
iCE40-HX8K Breakout Board Lattice iCE40-HX8K-CT256 7,680 $49 No 8 LEDs, 8 switches. Very similar to icoBoard, but no Raspberry Pi or pmod accessories.
iCE40 UltraPlus Lattice iCE40 UltraPlus FPGA 5280 $99 No Chip specs. 4 switchable FPGAs, and a rechargeable battery. Bluetooth module, LCD Display (240 x 240 RGB), RGB LED, microphones, audio output, compass, pressure, gyro, accelerometer.
Go Board Lattice ICE40 HX1K FPGA 1280 $65 No 4 LEDs, 4 buttons, Dual 7-Segment LED Display, VGA, 25 MHz on-board clock, 1 Mb Flash.
snickerdoodle Xilinx Zynq 7010 28K $95 Yes Xilinx Zynq 7-Series SoC - ARM Cortex-A9 processor, and Artix-7 FPGA. 125 IO pins. 1GB DDR2 RAM. Texas Instruments WiLink 8 wireless module for 802.11n Wi-Fi and Bluetooth 4.1. No LEDs or buttons, but easy to wire up your own on a breadboard. If you want to use a baseboard, you'll need a snickerdoodle black ($195) with the pins in the "down" orientation. (E.g. The "breakyBreaky breakout board" ($49) or piSmasher SBC ($195)). The snickerdoodle one only comes with pins in the "up" orientation and doesn't support any baseboards. But you can still plug the jumpers into the pins and wire up things on a breadboard.
numato Mimas A7 Xilinx Artix 7 52K $149 No 2Gb DDR3 RAM. Gigabit Ethernet. HDMI IN/OUT. 100MHz LVDS oscillator. 80 IOs. 7-segment display, LEDs, buttons. (Found in this Reddit thread.)
Ultra96 Xilinx Zynq UltraScale+ ZU3EG 154K $249 Yes Has one of the latest Xilinx SoCs. 2 GB (512M x32) LPDDR4 Memory. Wi-Fi / Bluetooth. Mini DisplayPort. 1x USB 3.0 type Micro-B, 2x USB 3.0 Type A. Audio I/O. Four user-controllable LEDs. No buttons and limited LEDs, but easy to wire up your own on a breadboard
Nexys A7-100T Xilinx Artix 7 15,850 $265 No . 128MiB DDR2 RAM. Ethernet port, PWM audio output, accelerometer, PDM microphone, microphone, etc. 16 switches, 16 LEDs. 7 segment displays. USB HID Host for mice, keyboards and memory sticks.

HDMI source + sink with CEC. 8 Total Processor I/O, 40 Total FPGA I/O. Also a faster version for $299 (Zybo Z7-20).
Arty A7 Xilinx Artix 7 15K $119 No 256MB DDR3L. 10/100 Mbps Ethernet. A few switches, buttons, LEDs.
DE10-Standard (specs) Altera Cyclone V 110K $350 Yes Dual-core Cortex-A9 processor. Lots of buttons, LEDs, and other peripherals.
DE10-Nano Altera Cyclone V 110K $130 Yes Same as DE10-Standard, but not as many peripherals, buttons, LEDs, etc.

Winner:

icoBoard ($100). (Buy it here.)
The icoBoard plugs into a Raspberry Pi, so it's similar to having a SoC. The iCE40-HX8K chip comes with 7,680 LUTs (logic elements.) This means that after you learn the basics and create some simple circuits, you'll also have enough logic elements to run the VexRiscv soft-core CPU (the lightweight Murax SoC.)
The icoBoard also supports a huge range of pluggable pmod accessories:
You can pick whatever peripherals you're interested in, and buy some more in the future.
Every FPGA vendor keeps their bitstream format secret. (Here's a Hacker News discussion about it.) The iCE40-HX8K bitstream has been fully reverse engineered by Project IceStorm, and there is an open-source set of tools that can compile Verilog to iCE40 bitstream.
This means that you have the freedom to do some crazy experiments, like:
You don't really have the same freedom to explore these things with Xilinx or Altera FPGAs. (Especially asynchronous circuits.)

Links:

Second Place:

iCE40-HX8K Breakout Board ($49)

Third Place:

numato Mimas A7 ($149).
An excellent development board with a Xilinx Artix 7 FPGA, so you can play with a bigger / faster FPGA and run a full RISC-V soft-core with all the options enabled, and a much higher clock speed. (The iCE40 FPGAs are a bit slow and small.)
Note: I've changed my mind several times as I learned new things. Here's some of my previous thoughts.

What did I buy?

I ordered a iCE40-HX8K Breakout Board to try out the IceStorm open source tooling. (I would have ordered an icoBoard if I had found it earlier.) I also bought a numato Mimas A7 so that I could experiment with the Artix 7 FPGA and Xilinx software (Vivado Design Suite.)

Questions

What can I do with an FPGA? / How many LUTs do I need?

X21S

This hashing algorithm was created specifically for Ritocoin, and was designed to resist FPGAs, ASICs, and NiceHash. It is X16S (16 algorithms shuffled and hashed),, followed by 5 additional hashing algorithms: haval256, tiger, lyra2, gost512, and sha256. The inclusion of lyra2 brings numerous advantages, making parallelization of the algorithm practically impossible, with each step relying on the previous step having already been computed. It is a “friendly” algorithm that makes GPUs produce much less heat and uses less electricity during mining.

Take your time to learn more about us in the below story of Ritocoin...

The spirit of Bitcoin continues to inspire, empower and enable people around the globe. Ten years later, just as it seemed Bitcoin was being defined by commercial agents and regulated governance, that same free and independent spirit imbued the Ravencoin community. In ten short months, however, 30% of the Ravencoin project’s net hash comes from NiceHash and the looming impact of the imminent FPGA mining cards and X16R bitstreams certainly promises to shake up the dream of this GPU miner’s darling.

Ravencoin’s fair launch genuinely inspired our developers and supporters. We admire the way Ravencoin came out swinging — fighting for fairness, an honest distribution of coins and a place where GPU miners could thrive. The asset layer attracted many more miners and investors to the pools. Many Ritocoin enthusiasts came from the Ravencoin community, and continue their association with that project.

The whole crypto ecosystem should appreciate the work begun by Ravencoin. Obviously they continue to inspire and motivate us to this day. It’s the reason we took action. We decided to start our own project which focuses upon at least two pillars of decentralized networks in the crypto space: community governance and a fair distribution of coins. It is a core belief throughout Ritocoin that in order to successfully develop and maintain this hacker’s playground — a place where a broad range of ideas could be tried and allowed to flourish — these two ideals must be allowed to drive and guide our community.

This deep focus on community choices creates a project flexible enough to support most ideas, and agile enough to define new frontiers.

A mining network’s distributed ledger is defined by its technology. Like many in the broader crypto-mining community, we value the GPU for its accessibility. These processors are available for purchase all around the world without any legal restrictions. GPUs are vastly more accessible for hobbyists and miners to acquire. They can be shipped nearly anywhere around the globe, a nice benefit to the popular secondary market which has sprung up much to the chagrin of PC gamers.

More constraints exist for the ASIC and FPGA miner. Laws in some parts of the world restrict people from using or buying ASIC and FPGA mining hardware. This alone is directly in confrontation with Ritocoin’s core values of decentralized stewardship and sovereignty.

The GPU, in essence, is like your voice. Anyone with the means of acquiring one GPU should be able to have their voice heard. ASIC and FPGA mining devalues the GPU miner’s voice and silos that coin’s network away from the small scale and personal mining operator. A truly community driven project means each stakeholder, regardless of size of contribution to the network’s net hash, has an opportunity to build, vote and direct.

If you are already familiar with our website, discord or whitepaper, you are probably aware that masternodes had been proposed as a feature of the network from the beginning. This opened the door to ongoing discussions in the Ritocoin community regarding

● A masternode’s true purpose

● What benefit they provide to the project

● How the benefit is realized

● The collateral

This discussion, governed entirely by stakeholders across the extended network yielded a defining moment for our vision of flexibility. We have not yet found the potential utility of masternodes, however, the conversation has not reached an extent to where we could abandon the idea. To quote one of our developers during this discussion on our Discord:

“Just want to give a reminder here that even though masternodes are on the roadmap, it is not set in stone. This coin belongs to the community and we will do what we as a community want to do. If we conclude that we want to take this coin a different direction than masternodes, then that is what we’ll do.” --traysi

We are all volunteers at Ritocoin. Our moderators and community leaders try to give immediate support to all users that require it. Contact us in Discord or Telegram, not only for support, but, proposing new ideas, revising old ones and just so you can find a place to get together and find people to hang out with. You are well within your rights to enjoy yourself at any given moment, and, should you feel so inclined to begin working with the team, we just so happen to be looking for ambitious individuals that see themselves as being part of a greater vision, are inspired by change, and inspired to be the change they want to see making things better in this world.

Join us in a space where your ideas to build something great can become a reality. We are eager to know what you think is best for the future of Rito. What steps would you take to become more resilient, stronger, fair and decentralized? Because at the end of the day, like it or not, love it or leave it.. this is your coin, too.

You can become a significant part of this project. We will help you further develop the role you wish to fill in the cryptocurrency space — influencer, developer, analyst, you name it. This is not a just-for-developer’s playground. We want the enthusiasts. We want the perplexed and the rabbit-hole divers. This is the coin for everyone who is trying to find their place on the path that Satoshi began unfolding in 2008 after the collapse of the housing market rippled out into the subsequent crash of global markets. That’s why we have Bitcoin, remember? Be your own bank. This is why Satoshi and Bitcoin.org kept their software open source. It’s up to us to keep the torch ablaze.

Community funds

For the first year, about 1% of mined coins are set aside into a developers fund that is used to provide bounties to the community developers who make substantial development contributions to the Ritocoin ecosystem. We have already paid out numerous bounties for important work that has already benefits Ritocoin in substantial ways. We also have another donation-driven community fund that has recently been put together for the purposes of doing fun contests and things like that.

Cooperation and collaborations

We have discovered a number of fatal flaws in the original Ravencoin codebase and worked with the Ravencoin developers to get those fixed in both Ritocoin and Ravencoin. This work has benefitted Ravencoin in numerous ways and we look forward to a long time of collaboration and cooperation between us and them. Many members of the Safecoin team are also in our discord group, and have collaborated with us in shaping the future decisions of Ritocoin. We have several thousand members in our group and they represent all walks of cryptocurrency life. We invite all coin developers, miners and enthusiasts to join our discord and be a part of this coin that truly belongs entirely to the community.

Block reward

A couple weeks ago we met for a scheduled meeting in our discord group and had a lengthy conversation about the block reward. Our block reward started at 5,000 RITO per block (every 60 seconds) just like Ravencoin. This extremely high number of coins coupled with the high profitability of mining led to unforeseen consequences with pools auto-exchanging the coin into bitcoin. This dumping by non-community miners had a very negative impact on the community sentiment and morale, as we watched the exchange price plunge. We looked at other coins and realized that this fate has befell many other coins with high block rewards. Following much discussion, we decided to change the reward structure. Starting around March 19th the block rewards will start to slowly go down in a curve until it reaches 1,000. Then the reduction will be even more slowed down with block rewards exponentially dropping at periodic intervals. We have posted charts on our website that shows what the long-term effects of our reward reducing algorithms will be. As a miner, the next 2 months will be a great time to mine and hold, while the block reward is still fairly high. We encourage all miners and cryptocurrency enthusiasts to take advantage of the current favourable block reward and build a nice holding for yourself. Then join the community and be a part of the fun we’re having with this project.
This post was prepared by a collaboration of multiple Ritocoin members and was posted to reddit by the core developer Trevali, who posts to reddit under the ritocoin username and will be very happy to answer any questions anybody may have about our project. Traysi (well known in the Ravencoin community) is also an active Ritocoin developer and may come to this thread if needed.
We welcome any questions from any of you regarding our project!

The Problem with PoW

The Problem with PoW
Miners have always had it rough..
"Frustrated Miners"

The Problem with PoW
(and what is being done to solve it)

Proof of Work (PoW) is one of the most commonly used consensus mechanisms entrusted to secure and validate many of today’s most successful cryptocurrencies, Bitcoin being one. Battle-hardened and having weathered the test of time, Bitcoin has demonstrated the undeniable strength and reliability of the PoW consensus model through sheer market saturation, and of course, its persistency.
In addition to the cost of powerful computing hardware, miners prove that they are benefiting the network by expending energy in the form of electricity, by solving and hashing away complex math problems on their computers, utilizing any suitable tools that they have at their disposal. The mathematics involved in securing proof of work revolve around unique algorithms, each with their own benefits and vulnerabilities, and can require different software/hardware to mine depending on the coin.
Because each block has a unique and entirely random hash, or “puzzle” to solve, the “work” has to be performed for each block individually and the difficulty of the problem can be increased as the speed at which blocks are solved increases.

Hashrates and Hardware Types

While proof of work is an effective means of securing a blockchain, it inherently promotes competition amongst miners seeking higher and higher hashrates due to the rewards earned by the node who wins the right to add the next block. In turn, these higher hash rates benefit the blockchain, providing better security when it’s a result of a well distributed/decentralized network of miners.
When Bitcoin first launched its genesis block, it was mined exclusively by CPUs. Over the years, various programmers and developers have devised newer, faster, and more energy efficient ways to generate higher hashrates; some by perfecting the software end of things, and others, when the incentives are great enough, create expensive specialized hardware such as ASICs (application-specific integrated circuit). With the express purpose of extracting every last bit of hashing power, efficiency being paramount, ASICs are stripped down, bare minimum, hardware representations of a specific coin’s algorithm.
This gives ASICS a massive advantage in terms of raw hashing power and also in terms of energy consumption against CPUs/GPUs, but with significant drawbacks of being very expensive to design/manufacture, translating to a high economic barrier for the casual miner. Due to the fact that they are virtual hardware representations of a single targeted algorithm, this means that if a project decides to fork and change algorithms suddenly, your powerful brand-new ASIC becomes a very expensive paperweight. The high costs in developing and manufacturing ASICs and the associated risks involved, make them unfit for mass adoption at this time.
Somewhere on the high end, in the vast hashrate expanse created between GPU and ASIC, sits the FPGA (field programmable gate array). FPGAs are basically ASICs that make some compromises with efficiency in order to have more flexibility, namely they are reprogrammable and often used in the “field” to test an algorithm before implementing it in an ASIC. As a precursor to the ASIC, FPGAs are somewhat similar to GPUs in their flexibility, but require advanced programming skills and, like ASICs, are expensive and still fairly uncommon.

2 Guys 1 ASIC

One of the issues with proof of work incentivizing the pursuit of higher hashrates is in how the network calculates block reward coinbase payouts and rewards miners based on the work that they have submitted. If a coin generated, say a block a minute, and this is a constant, then what happens if more miners jump on a network and do more work? The network cannot pay out more than 1 block reward per 1 minute, and so a difficulty mechanism is used to maintain balance. The difficulty will scale up and down in response to the overall nethash, so if many miners join the network, or extremely high hashing devices such as ASICs or FPGAs jump on, the network will respond accordingly, using the difficulty mechanism to make the problems harder, effectively giving an edge to hardware that can solve them faster, balancing the network. This not only maintains the block a minute reward but it has the added side-effect of energy requirements that scale up with network adoption.
Imagine, for example, if one miner gets on a network all alone with a CPU doing 50 MH/s and is getting all 100 coins that can possibly be paid out in a day. Then, if another miner jumps on the network with the same CPU, each miner would receive 50 coins in a day instead of 100 since they are splitting the required work evenly, despite the fact that the net electrical output has doubled along with the work. Electricity costs miner’s money and is a factor in driving up coin price along with adoption, and since more people are now mining, the coin is less centralized. Now let’s say a large corporation has found it profitable to manufacture an ASIC for this coin, knowing they will make their money back mining it or selling the units to professionals. They join the network doing 900 MH/s and will be pulling in 90 coins a day, while the two guys with their CPUs each get 5 now. Those two guys aren’t very happy, but the corporation is. Not only does this negatively affect the miners, it compromises the security of the entire network by centralizing the coin supply and hashrate, opening the doors to double spends and 51% attacks from potential malicious actors. Uncertainty of motives and questionable validity in a distributed ledger do not mix.
When technology advances in a field, it is usually applauded and welcomed with open arms, but in the world of crypto things can work quite differently. One of the glaring flaws in the current model and the advent of specialized hardware is that it’s never ending. Suppose the two men from the rather extreme example above took out a loan to get themselves that ASIC they heard about that can get them 90 coins a day? When they join the other ASIC on the network, the difficulty adjusts to keep daily payouts consistent at 100, and they will each receive only 33 coins instead of 90 since the reward is now being split three ways. Now what happens if a better ASIC is released by that corporation? Hopefully, those two guys were able to pay off their loans and sell their old ASICs before they became obsolete.
This system, as it stands now, only perpetuates a never ending hashrate arms race in which the weapons of choice are usually a combination of efficiency, economics, profitability and in some cases control.

Implications of Centralization

This brings us to another big concern with expensive specialized hardware: the risk of centralization. Because they are so expensive and inaccessible to the casual miner, ASICs and FPGAs predominantly remain limited to a select few. Centralization occurs when one small group or a single entity controls the vast majority hash power and, as a result, coin supply and is able to exert its influence to manipulate the market or in some cases, the network itself (usually the case of dishonest nodes or bad actors).
This is entirely antithetical of what cryptocurrency was born of, and since its inception many concerted efforts have been made to avoid centralization at all costs. An entity in control of a centralized coin would have the power to manipulate the price, and having a centralized hashrate would enable them to affect network usability, reliability, and even perform double spends leading to the demise of a coin, among other things.
The world of crypto is a strange new place, with rapidly growing advancements across many fields, economies, and boarders, leaving plenty of room for improvement; while it may feel like a never-ending game of catch up, there are many talented developers and programmers working around the clock to bring us all more sustainable solutions.

The Rise of FPGAs

With the recent implementation of the commonly used coding language C++, and due to their overall flexibility, FPGAs are becoming somewhat more common, especially in larger farms and in industrial setting; but they still remain primarily out of the hands of most mining enthusiasts and almost unheard of to the average hobby miner. Things appear to be changing though, one example of which I’ll discuss below, and it is thought by some, that soon we will see a day when mining with a CPU or GPU just won’t cut it any longer, and the market will be dominated by FPGAs and specialized ASICs, bringing with them efficiency gains for proof of work, while also carelessly leading us all towards the next round of spending.
A perfect real-world example of the effect specialized hardware has had on the crypto-community was recently discovered involving a fairly new project called VerusCoin and a fairly new, relatively more economically accessible FPGA. The FPGA is designed to target specific alt-coins whose algo’s do not require RAM overhead. It was discovered the company had released a new algorithm, kept secret from the public, which could effectively mine Verus at 20x the speed of GPUs, which were the next fastest hardware types mining on the Verus network.
Unfortunately this was done with a deliberately secret approach, calling the Verus algorithm “Algo1” and encouraging owners of the FPGA to never speak of the algorithm in public channels, admonishing a user when they did let the cat out of the bag. The problem with this business model is that it is parasitic in nature. In an ecosystem where advancements can benefit the entire crypto community, this sort of secret mining approach also does not support the philosophies set forth by the Bitcoin or subsequent open source and decentralization movements.
Although this was not done in the spirit of open source, it does hint to an important step in hardware innovation where we could see more efficient specialized systems within reach of the casual miner. The FPGA requires unique sets of data called a bitstream in order to be able to recognize each individual coin’s algorithm and mine them. Because it’s reprogrammable, with the support of a strong development team creating such bitstreams, the miner doesn’t end up with a brick if an algorithm changes.

All is not lost thanks to.. um.. Technology?

Shortly after discovering FPGAs on the network, the Verus developers quickly designed, tested, and implemented a new, much more complex and improved algorithm via a fork that enabled Verus to transition smoothly from VerusHash 1.0 to VerusHash 2.0 at block 310,000. Since the fork, VerusHash 2.0 has demonstrated doing exactly what it was designed for- equalizing hardware performance relative to the device being used while enabling CPUs (the most widely available “ASICs”) to mine side by side with GPUs, at a profit and it appears this will also apply to other specialized hardware. This is something no other project has been able to do until now. Rather than pursue the folly of so many other projects before it- attempting to be “ASIC proof”, Verus effectively achieved and presents to the world an entirely new model of “hardware homogeny”. As the late, great, Bruce Lee once said- “Don’t get set into one form, adapt it and build your own, and let it grow, be like water.”
In the design of VerusHash 2.0, Verus has shown it doesn’t resist progress like so many other new algorithms try to do, it embraces change and adapts to it in the way that water becomes whatever vessel it inhabits. This new approach- an industry first- could very well become an industry standard and in doing so, would usher in a new age for proof of work based coins. VerusHash 2.0 has the potential to correct the single largest design flaw in the proof of work consensus mechanism- the ever expanding monetary and energy requirements that have plagued PoW based projects since the inception of the consensus mechanism. Verus also solves another major issue of coin and net hash centralization by enabling legitimate CPU mining, offering greater coin and hashrate distribution.
Digging a bit deeper it turns out the Verus development team are no rookies. The lead developer Michael F Toutonghi has spent decades in the field programming and is a former Vice President and Technical Fellow at Microsoft, recognized founder and architect of Microsoft's .Net platform, ex-Technical Fellow of Microsoft's advertising platform, ex-CTO, Parallels Corporation, and an experienced distributed computing and machine learning architect. The project he helped create employs and makes use of a diverse myriad of technologies and security features to form one of the most advanced and secure cryptocurrency to date. A brief description of what makes VerusCoin special quoted from a community member-
"Verus has a unique and new consensus algorithm called Proof of Power which is a 50% PoW/50% PoS algorithm that solves theoretical weaknesses in other PoS systems (Nothing at Stake problem for example) and is provably immune to 51% hash attacks. With this, Verus uses the new hash algorithm, VerusHash 2.0. VerusHash 2.0 is designed to better equalize mining across all hardware platforms, while favoring the latest CPUs over older types, which is also one defense against the centralizing potential of botnets. Unlike past efforts to equalize hardware hash-rates across different hardware types, VerusHash 2.0 explicitly enables CPUs to gain even more power relative to GPUs and FPGAs, enabling the most decentralizing hardware, CPUs (due to their virtually complete market penetration), to stay relevant as miners for the indefinite future. As for anonymity, Verus is not a "forced private", allowing for both transparent and shielded (private) transactions...and private messages as well"

If other projects can learn from this and adopt a similar approach or continue to innovate with new ideas, it could mean an end to all the doom and gloom predictions that CPU and GPU mining are dead, offering a much needed reprieve and an alternative to miners who have been faced with the difficult decision of either pulling the plug and shutting down shop or breaking down their rigs to sell off parts and buy new, more expensive hardware…and in so doing present an overall unprecedented level of decentralization not yet seen in cryptocurrency.
Technological advancements led us to the world of secure digital currencies and the progress being made with hardware efficiencies is indisputably beneficial to us all. ASICs and FPGAs aren’t inherently bad, and there are ways in which they could be made more affordable and available for mass distribution. More than anything, it is important that we work together as communities to find solutions that can benefit us all for the long term.

In an ever changing world where it may be easy to lose sight of the real accomplishments that brought us to this point one thing is certain, cryptocurrency is here to stay and the projects that are doing something to solve the current problems in the proof of work consensus mechanism will be the ones that lead us toward our collective vision of a better world- not just for the world of crypto but for each and every one of us.

Great.
@Milo Was there PRs for Android and iOS?
MiloLast Friday at 4:01 PM
Yes, I've made a video. Give me a second I'll share it asap.

LSJI07 - MBITLast Friday at 4:12 PM
what are the proposed 22 algos in x22r? i could only find the original 16 plus 5 on x21.
TronLast Friday at 4:12 PM
Likely the 5 from x21 and find one more.
We need to make sure they're all similar in time profile.
liqdmetalLast Friday at 4:14 PM
should we bother fixing a asic-problem that we dont know exists for sure or not?
TronLast Friday at 4:14 PM
That's the 170 million dollar question.
[Dev-Happy] BlondfrogsLast Friday at 4:14 PM
I would prefer to be proactive not reactive.
imo
JerozLast Friday at 4:14 PM
same
LSJI07 - MBITLast Friday at 4:15 PM
RIPEMD160 is a golden oldie but not sure on hash speed compared to the others.
liqdmetalLast Friday at 4:15 PM
in my mind we should focus on the restricted messaging etc
Sevvy (y rvn pmp?)Last Friday at 4:15 PM
probably won't know if the action was needed until after you take the action
liqdmetalLast Friday at 4:15 PM
we are at risk of being interventionistas
acting under opacity
TronLast Friday at 4:15 PM
Needs to spit out at least 256 bit. Preferably 512 bit.
LSJI07 - MBITLast Friday at 4:15 PM
ok
TronLast Friday at 4:15 PM
If it isn't 512 bit, it'll cause some extra headache for the GPU mining software.
liqdmetalLast Friday at 4:16 PM
i seek to avoid iatrogenics
TronLast Friday at 4:16 PM
Similar to the early problems when all the algos except the first one were built for 64-bytes (512-bit) inputs.
Had to look that one up. TIL iatrogenics
JerozLast Friday at 4:17 PM
I have to google most of @liqdmetal's vocabulary :smile:
liqdmetalLast Friday at 4:17 PM
@Tron tldr: basically the unseen, unintended negative side effects of the asic "cure"
Sevvy (y rvn pmp?)Last Friday at 4:18 PM
10 dolla word
liqdmetalLast Friday at 4:19 PM
we need a really strong case to intervene in what has been created.
TronLast Friday at 4:19 PM
I agree. I'm less concerned with the technical risk than I am the potential split risk experienced multiple times by Monero.
Sevvy (y rvn pmp?)Last Friday at 4:20 PM
tron do you agree that forking the ravencoin chain presents unique risks compared to other chains that aren't hosting assets?
JerozLast Friday at 4:21 PM
Yes, if you fork, you need to figure out for each asset which one you want to support.
Sevvy (y rvn pmp?)Last Friday at 4:21 PM
yeah. and the asset issuer could have a chain preference
TronLast Friday at 4:22 PM
@Sevvy (y rvn pmp?) Sure. Although, I'd expect that the asset issuers will be honor the assets on the dominant chain. Bigger concern is the branding confusion of multiple forks. See Bitcoin, Bitcoin Cash, Bitcoin SV for an example. We know they're different, but do non-crypto folks?
Hans_SchmidtLast Friday at 4:22 PM
I thought that the take-away from the recently published analyses and discussions was that ASICs for RVN may be active, but if so then they are being not much more effective than GPUs.
Sevvy (y rvn pmp?)Last Friday at 4:22 PM
agreed on all accounts there tron
TronLast Friday at 4:23 PM
I'm not yet convinced ASICs are on the network.
KAwARLast Friday at 4:23 PM
It would be better to damage an asic builder by forking after they made major expenses. Creating for them the type of deficit that could be negated by just buying instead of mining. Asic existence should be 100 percent confirmed before fork.
liqdmetalLast Friday at 4:23 PM
170million dollar question is right.lol
TronLast Friday at 4:24 PM
I've had someone offer to connect me to the folks at Fusion Silicon.
Sevvy (y rvn pmp?)Last Friday at 4:25 PM
yes. and if they are active on the network they are not particularly good ASICs
which makes it a moot point probably
TronLast Friday at 4:26 PM
The difficult part of this problem is that by the time everyone agrees that ASICs are problematic on the network, then voting the option in is likely no longer an option.
Sevvy (y rvn pmp?)Last Friday at 4:26 PM
yes. part of me wonders if we would say "okay, the clock on the asic countdown is reset by this new algo. but now the race is on"
[Dev-Happy] BlondfrogsLast Friday at 4:26 PM
There are always risks when making a change that will fork the network. We want wait to long though, as tron said. It wont be a voting change. it will be a mandatory change at a block number.
Sevvy (y rvn pmp?)Last Friday at 4:26 PM
acknowledge the inevitable
MiloLast Friday at 4:27 PM
I had just a small question from my side. When do you think the android version would be published, and do you maybe have a time-frame for the others?
TronLast Friday at 4:27 PM
Quick poll. How would everyone here feel about a BIP9 option - separate from the new features that can be voted in?
KAwARLast Friday at 4:27 PM
Maybe voting should not be a strictly blockchain vote. A republic and a democratic voice?
[Dev-Happy] BlondfrogsLast Friday at 4:27 PM
@Milo We can try and get a beta out next week, and publish soon after that.
MiloLast Friday at 4:28 PM
@[Dev-Happy] Blondfrogs :thumbsup::slight_smile:
[Dev-Happy] BlondfrogsLast Friday at 4:28 PM
BIP9 preemptive vote. I like it.
TronLast Friday at 4:30 PM
The advantage to a BIP9 vote is that it puts the miners and mining pools at a clear majority before activation.
LSJI07 - MBITLast Friday at 4:30 PM
Centralisation is inevitable unless we decide to resist it. ASIC's are market based and know the risks and rewards possible. A key step in resisting is sending a message. An algo change to increase asic resistance is imho a strong message. A BIP9 vote now would also be an indicator of bad actors early....
TronLast Friday at 4:30 PM
The disadvantage is that it may not pass if the will isn't there.
LSJI07 - MBITLast Friday at 4:30 PM
Before assets are on main net and cause additional issues.
KAwARLast Friday at 4:31 PM
I am not schooled in coding to have an educated voice. I only understand social problems and how it affects the economy.
SpyderDevLast Friday at 4:31 PM
All are equal on RVN
TronLast Friday at 4:31 PM
It is primarily a social problem. The tech change is less risky and is easier than the social.
LSJI07 - MBITLast Friday at 4:32 PM
All can have a share....people who want more of a share however pay for the privilege and associated risks.
KAwARLast Friday at 4:33 PM
Assets and exchange listings need to be consistent and secure.
brutoidLast Friday at 4:36 PM
I'm still not entirely clear on what the overall goal to the algo change is? Is it just to brick the supposed ASICs (unknown 45%) which could still be FPGAs as seen from the recent block analysis posted in the nest. Is the goal to never let ASICs on? Is it to brick FPGAs ultimately. Are we making Raven strictly GPU only? I'm still unclear
LSJI07 - MBITLast Friday at 4:37 PM
What about the future issue of ASICs returning after a BIP9 fork "soon"? Are all following the WP as a community? i.e asic resistant or are we prepared to change that to asic resistant for early coin emission. Ideally we should plan for the future. Could the community make a statement that no future algo changes will be required to incentivise future public asic manufacturers?
Lol. Same question @brutoid
brutoidLast Friday at 4:37 PM
Haha it is
You mind-beamed me!
[Dev-Happy] BlondfrogsLast Friday at 4:38 PM
The is up to the community.
Currently, the feel seems like the community is anti asic forever.
The main issue is getting people to upgrade.
KAwARLast Friday at 4:38 PM
Clarity is important. Otherwise we are attacking windmills like Don Quixote.
brutoidLast Friday at 4:39 PM
I'm not getting the feeling of community ASIC hate if the last few weeks of discussion are anything to go by?
Hans_SchmidtLast Friday at 4:39 PM
A unilateral non-BIP9 change at a chosen block height is a serious thing, but anti-ASIC has been part of the RVN philosophy since the whitepaper and is therefore appropriate for that purpose.
[Dev-Happy] BlondfrogsLast Friday at 4:39 PM
We can use the latest release as an example. It was a non forking release, announced for 2 weeks. and only ~30% of the network has upgraded.
TronLast Friday at 4:39 PM
@Hans_Schmidt Well said.
liqdmetalLast Friday at 4:40 PM
I'm not concerned about a "asic hardware problem" so much as I believe it more likely what we are seeing is several big fish miners (perhaps a single really big fish). For now I recommend standing pat on x16r. In the future I can see an algo upgrade fork to keep the algo up to date. If we start fighting against dedicated x16r hashing machines designed and built to secure our network we are more likely to go down in flames. The custom SHA256 computers that make the bitcoin the most secure network in existence are a big part of that security. If some party has made an asic that performs up to par or better than FPGA or GPU on x16r, that is a positive for this network, a step towards SHA256 security levels. It is too bad the community is in the dark regarding their developments. Therefore I think the community has to clarify its stance towards algorithm changes. I prefer a policy that will encourage the development of mining software, bitstreams and hardware by as many parties as possible. The imminent threat of ALGO fork screws the incentive up for developers.
JerozLast Friday at 4:40 PM
@brutoid the vocal ones are lenient towards asics, but the outcome of the 600+ votes seemed pretty clear.
brutoidLast Friday at 4:40 PM
This is my confusion
TronLast Friday at 4:41 PM
More hashes are only better if the cost goes up proportionally. Machines that do more hashes for less $ doesn't secure the network more, and trends towards centralization.
JerozLast Friday at 4:41 PM
I would argue for polling ever so often as it certainly will evolve dynamically with the state of crypto over time.
TronLast Friday at 4:41 PM
Measure security in two dimensions. Distribution, and $/hash.
liqdmetalLast Friday at 4:41 PM
and volume of hash
traysiLast Friday at 4:42 PM
45% of the hashrate going to one party is unhealthy, and standing pat on x16r just keeps that 45% where it is.
TronLast Friday at 4:42 PM
Volume doesn't matter if the cost goes down. For example, lets say software shows up that does 1000x better than the software from yesterday, and everyone moves to it. That does not add security. Even if the "difficulty" and embedded hashes took 1000x more attempts to find.
brutoidLast Friday at 4:42 PM
My issue is defintely centralization of hash and not so much what machine is doing it. I mine with both GPU and FPGA. Of course, the FPGAs are not on raven
TJayLast Friday at 4:44 PM
easy solution is just to replace a few of 16 current hash functions, without messing with x21r or whatever new shit
TronLast Friday at 4:44 PM
How do folks here feel about allowing CPUs back in the game?
traysiLast Friday at 4:44 PM
Botnets is my concern with CPUs
brutoidLast Friday at 4:44 PM
Botnets is my concern
SpyderDevLast Friday at 4:44 PM
Yes please.
LSJI07 - MBITLast Friday at 4:44 PM
the poll votes seem not very security conscious. More of day miners chasing profits. I love them bless! Imho the future is bright for raven, however these issues if not sorted out now will bite hard long term when asset are on the chain and gpu miners are long gone.....
ZaabLast Friday at 4:45 PM
How has the testing of restricted assets been on the test net?
liqdmetalLast Friday at 4:45 PM
Agreed. I dont think x16r is obsolete like that yet however
[Dev-Happy] BlondfrogsLast Friday at 4:45 PM
@Zaab not enough testing at the moment.
HedgerLast Friday at 4:45 PM
Yes, how is the Testing going?
justinjjaLast Friday at 4:45 PM
Like randomX or how are cpus going to be back in the game?
TronLast Friday at 4:45 PM
@Zaab Just getting started at testing at the surface level (RPC calls), and fixing as we go.
ZaabLast Friday at 4:45 PM
And or any updates on the review of dividend code created by the community
Lokar -=Kai=-Last Friday at 4:45 PM
if the amount of hash the unknown pool has is fixed as standarderror indicated then waiting for the community of FPGAers to get onto raven might be advantageous if the fork doesn't hurt FPGAs.
ZaabLast Friday at 4:45 PM
Can't rememeber who was on it
SpyderDevLast Friday at 4:45 PM
@Zaab But we are working on it...
Lokar -=Kai=-Last Friday at 4:46 PM
more hash for votes
JerozLast Friday at 4:46 PM
@Maldon is, @Zaab
TronLast Friday at 4:46 PM
@Zaab There are unit tests and functional tests already, but we'd like more.
[Dev-Happy] BlondfrogsLast Friday at 4:46 PM
@Zaab Dividend code is currently adding test cases for better security. Should have more update on that next meeting
KAwARLast Friday at 4:46 PM
Absolute democracy seems to resemble anarchy or at least civil war. In EVE online they have a type of community voice that get voted in by the community.
ZaabLast Friday at 4:46 PM
No worries was just curious if it was going as planned or significant issues were being found
Obviously some hiccups are expected
More testing is always better!

KAwARLast Friday at 4:49 PM
I am trying to be serious...
ZaabLast Friday at 4:49 PM
Sorry back to the ascii topic!
traysiLast Friday at 4:49 PM
@Tron What do we need in order to make progress toward a decision on the algo? Is there a plan or a roadmap of sorts to get us some certainty about what we're going to do?
LSJI07 - MBITLast Friday at 4:50 PM
Could we have 3 no BIP9 votes? No1 Friendly to asics, retain status quo. No2 change to x17r minimal changes etc, with no additional future PoW/algo upgrades. No3. Full Asic resistance x22r and see what happens...
:thonk~1:
Sounds messy....
TronLast Friday at 4:51 PM
Right now we're in research mode. We're building CNv4 so we can run some metrics. If that goes well, we can put together x22rc and see how it performs. It will likely gore everyone's ox. CPUs can play, GPUs work, but aren't dominant. ASICs VERY difficult, and FPGAs will have a tough time.
ZaabLast Friday at 4:51 PM
Yeah i feel like the results would be unreliable
TronLast Friday at 4:51 PM
Is this good, or do we lose everyone's vote?
PlayHardLast Friday at 4:52 PM
Fpga will be dead
Lokar -=Kai=-Last Friday at 4:52 PM
why isn;t a simple XOR or something on the table?
ZaabLast Friday at 4:52 PM
The multiple bip9 that is
Lokar -=Kai=-Last Friday at 4:52 PM
something asic breaking but doesn't greatly complicate ongoing efforts for FPGA being my point.
justinjjaLast Friday at 4:52 PM
How are you going to vote for x22rc?
Because if by hashrate that wouldn't pass.
traysiLast Friday at 4:52 PM
Personally I like the idea of x22rc but I'd want to investigate the botnet threat if CPUs are allowed back in.
TronLast Friday at 4:52 PM
XOR is on the table, and was listed in my Medium post. But, the social risk of chain split remains, for very little gain.
traysiLast Friday at 4:53 PM
@Lokar -=Kai=- A small change means that whoever has 45% can probably quickly adapt.
LSJI07 - MBITLast Friday at 4:53 PM
Research sounds good. x22rc could be reduce to x22r for simplicity...
TronLast Friday at 4:53 PM
x22r is a viable option. No CNv4.
LSJI07 - MBITLast Friday at 4:53 PM
Don't know how much time we have to play with though...
Lokar -=Kai=-Last Friday at 4:53 PM
if they have FPGAs yes if they have ASIC then not so much, but I guess that gets to the point, what exactly are we trying to remove from the network?
PlayHardLast Friday at 4:54 PM
Guys my name is Arsen and we designed x16r fpga on bcus. Just about to release it to the public. I am buzzdaves partner.
Cryptonight
Will kill us
But agreed
Asic is possible on x16r
And you dont need 256 core

traysiLast Friday at 4:55 PM
Hi Arsen. Are you saying CN will kill "us" meaning RVN, or meaning FPGA?
JerozLast Friday at 4:55 PM
This is what im afraid of ^ an algo change killing FPGA as I have the feeling there is a big fpga community working on this
PlayHardLast Friday at 4:55 PM
Fpgas ))
whitefire990Last Friday at 4:55 PM
I am also about to release X16R for CVP13 + BCU1525 FPGA's. I'm open to algo changes but I really don't believe in CPU mining because of botnets. Any CNv4 shifts 100% to CPU mining, even if it is only 1 of the 22 functions.
Lokar -=Kai=-Last Friday at 4:55 PM

whitefire990Last Friday at 4:56 PM
Right now with both Buzzdave/Altered Silicon and myself (Zetheron) about to release X16R for FPGA's, then the 45% miner's share will decrease to 39% or less.
PlayHardLast Friday at 4:56 PM
Will be dead for fpga
LSJI07 - MBITLast Friday at 4:56 PM
sound so x22r is fpga "friendly" ... more so than asic anyway...
PlayHardLast Friday at 4:56 PM
But a change must be planned
X16r is no way possible to avoid asics
TJayLast Friday at 4:56 PM
@LSJI07 - MBIT I would say less friendly...
whitefire990Last Friday at 4:57 PM
As I mentioned in thenest discussion, asic resistance increases with the square of the number of functions, so X21R is more asic resistant than X16R, but both are pretty resistant
PlayHardLast Friday at 4:58 PM
Yeah more algos make it heavier on ASIC
DirkDiggler (Citadel Architect)Last Friday at 4:58 PM
My interpretation of the whitepaper was that we used x16r as it was brand new (thus ASIC resistant), and that was to ensure a fair launch... We've launched... I don't like the idea of constantly forking to avoid the inevitable ASICs.
x16r was a great "experiment" before we had any exchange listings... that ship has sailed though... not sure about all these x22rs lmnop changes
KAwARLast Friday at 5:00 PM
I believe that it is easier to change the direction of a bicycle than an oil tanker. We feel more like a train. We should lay out new tracks and test on them and find benefits that are acceptable to everyone except train robbers. Then open the new train station with no contentious feelings except a silently disgruntled minority group. ???
Hans_SchmidtLast Friday at 5:01 PM
The most productive action the community can do now re ASICs is to voice support for the devs to make a non-BIP9 change at a chosen block height if/when the need is clear. That removes the pressure to act rashly to avoid voting problems.
LSJI07 - MBITLast Friday at 5:01 PM
Thats why im proposing to fork at least once to a more asic resistant algo (but FPGA "friendly/possible"), with the proviso ideally that no more PoW algo forks are require to provide future ASICs some opportunity to innovate with silicon and efficiency.
TJayLast Friday at 5:01 PM
folks should take into account, that high end FPGAs like BCU1525 on x16r can't beat even previous gen GPUs (Pascal) in terms of hash cost. so they aren't a threat to miners community
PlayHardLast Friday at 5:02 PM
A proper change
Requires proper research
eyz (Silence)Last Friday at 5:02 PM
Just so I'm clear here, we are trying to boot ASICS, don't want CPUs because of Botnets, and are GPU and FPGA friendly right?
PlayHardLast Friday at 5:02 PM
It is not a quick one day process
eyz (Silence)Last Friday at 5:02 PM
If there is a bip9 vote there needs to be a clear explanation as I feel most in the community don't understand exactly what we are trying to fix
TronLast Friday at 5:03 PM
@Hans_Schmidt I like that route. It has some game theoretics. It gives time for miners to adapt. It is only used if needed. It reduces the likelihood of ASICs dominating the network, or even being built.
[Dev-Happy] BlondfrogsLast Friday at 5:03 PM
Hey guys. great convo. We are of course looking to do the best thing for the community and miner. We are going to be signing off here though.
justinjjaLast Friday at 5:03 PM
TJay that comes down to power cost.
If your paying 4c/kw gpus all the way.
But if your a home miner in europe an fpga is your only chance
LSJI07 - MBITLast Friday at 5:03 PM
@Hans_Schmidt How do we decide the block limit and when sufficient evidence is available? I would say we have had much compelling information to date...
