[OWL WATCH] Waiting for "IOTA TIME" 27;
Disclaimer: This is my editing, so there could be always some misunderstandings and exaggerations, plus many convos are from 'spec channel', so take it with a grain of salt, pls. + I added some recent convos afterward. -------------------------------------------------- 📷 Luigi Vigneri [IF]어제 오후 8:26 Giving the opportunity to everybody to set up/run nodes is one of IOTA's priority. A minimum amount of resources is obviously required to prevent easy attacks, but we are making sure that being active part of the IOTA network can be possible without crazy investments. we are building our solution in such a way that the protocol is fair and lightweight. 📷 Hans Moog [IF]어제 오후 11:24 IOTA is not "free to use" but it's - fee-less you have tokens? you can send them around for free 📷 Hans Moog [IF]어제 오후 11:25 you have no tokens? you have to pay to use the network 📷 lekanovic어제 오후 11:25 I think it is a smart way to avoid the spamming network problem 📷 Hans Moog [IF]어제 오후 11:26 owning tokens is essentially like owning a share of the actual network and the throughput it can process 📷 Hans Moog [IF]어제 오후 11:26**** if you don't need all of that yourself, you can rent it out to people and earn money 📷 Hans Moog [IF]어제 오후 11:27 mana = tokens * time since you own them simplified 📷 Hans Moog [IF]어제 오후 11:27 the longer you hold your tokens and the more you have, the more mana you have but every now and then you have to move them to "realize" that mana 📷 lekanovic어제 오후 11:28 Is there any other project that is using a Mana solution to the network fee problem ? 📷 Hans Moog [IF]어제 오후 11:28 nah the problem with current protocol is that they are leader based 📷 Hans Moog [IF]어제 오후 11:29 you need absolute consensus on who the current leaders are and what their influence in the network is that's how blockchains works 📷 Hans Moog [IF]어제 오후 11:29 if two block producers produce 2 blocks at the same time, then you have to choose which one wins and where everybody attaches their next block to IOTA works differently and doesn't need to choose a single leader we therefore have a much bigger flexibility of designing our sybil protection mechanisms in a way, mana is also supposed to solve the problem of "rewarding" the infrastructure instead of the validators in blockchain only the miners get all the money running a node and even if it's one that is used by a lot of people will only cost you won't get anything back no fees, nothing the miners get it all 📷 Hans Moog [IF]어제 오후 11:31 in IOTA, the node operators receive the mana which gives them a share of the network throughput 📷 Hans Moog [IF]어제 오후 11:32 because in blockchain you need to decide whose txs become part of the blocks and it's not really based on networking protocols like AIMD 📷 lekanovic어제 오후 11:33 And the more Mana your node have, the more trust your node has and you have more to say in the FPC, is that correct? 📷 Hans Moog [IF]어제 오후 11:33 yeah a node that has processed a lot of txs of its users will have more mana than other nodes and therefore a bigger say in deciding conflicts its a direct measure of "trust" by its users 📷 lekanovic어제 오후 11:34 And choosing committee for dRNG would be done on L1 protocol level? Everything regarding Mana will be L1 level, right? 📷 Hans Moog [IF]어제 오후 11:35 Yeah Mana is layer1, but will also be used as weight in L2 solutions like smart contracts 📷 lekanovic어제 오후 11:35 And you are not dependant on using SC to implement this 📷 Hans Moog [IF]어제 오후 11:35 No, you don't need smart contracts That's all the base layer 📷 Hans Moog [IF]어제 오후 11:37 'Time' actually takes into account things like decay So it doesn't just increase forever It's close to "Demurrage" in monetary theory 📷 lekanovic어제 오후 11:36 For projects to be able to connect to Polkadot or Cosmos, you need to get the state of the ledger. Will it be possible to get the Tangle state? If this would be possible, then I think it would be SUPER good for IOTA 📷 Hans Moog [IF]어제 오후 11:38 Yeah but polkadot is not connecting other dlts Just inhouse stuff 📷 Hyperware어제 오후 11:39 Is there still a cap on mana so that the rich don't get richer? 📷 Hans Moog [IF]어제 오후 11:39 Yes mana is capped 📷 TangleAccountant어제 오후 11:39 u/HansMoog [IF] My first thought is thatthe evolution of this renting system will lead to several big mana renting companies that pool together tons of token holders mana. That way businesses looking to rent mana just need to deal with a reliable mana renting company for years instead of a new individualevery couple of months (because life happens and you don't know if that individual will need to sell their IOTAs due to personal reasons). Any thoughts on this? 📷 Hans Moog [IF]어제 오후 11:41 u/TangleAccountantyes that is likely - but also not a bad thing - token holders will have a place to get their monthly payout and the companies that want to use the tangle without having tokens have a place to pay 📷 TangleAccountant어제 오후 11:42 Oh I completely agree.That's really cool. I'll take a stab at creating one of those companies in the US. 📷 Hans Moog [IF]어제 오후 11:42 And everybody who wants to run a node themselves or has tokens and wants use the tangle for free can do so But "leachers" that would want to use the network for free won't be able to do so I mean ultimately there will always be "fees", as there is no "free lunch". You have a certain amount of resources that a network can process and you have a certain demand. And that will naturally result in fees based on supply / demand what you can do however is to build a system where the actual users of that system that legitimately want to use it can do so for free, just because they already "invest" enough by having tokens or running infrastructure they are already contributing to the well-being of the network through these two aspects alone it would be stupid to ask those guys for additional fees and mana essentially tries to be such a measure of honesty among the users 📷 Hyperware어제 오후 11:47 It's interesting from an investment perspective that having tokens/mana is like owning a portion of the network. 📷 Hans Moog [IF]어제 오후 11:48 Yeah, you are owning a certain % of the throughput and whatever the price will ultimately be to execute on this network - you will earn proportionally but you have to keep in mind that we are trying to build the most efficient DLT that you could possibly ever build 📷 semibaron어제 오후 11:48 The whole mana (tokens) = share of network throuput sounds very much like EOS tbh Just that EOS uses DPoS 📷 Hans Moog [IF]어제 오후 11:50 yeah i mean there is really not too many new things under the sun - you can just tweak a few things here and there, when it comes to distributing resources DPoS is simply not very nice from a centralization aspect 📷 Hans Moog [IF]어제 오후 11:50 at least not the way EOS does it delegating weights is 1 thing but assuming that the weight will always be in a way that 21 "identities" run the whole network is bad in the current world you see a centralization of power but ultimately we want to build a future where the wealth is more evenly distributed and the same goes for voting power 📷 Hans Moog [IF]어제 오후 11:52 blockchain needs leader selection it only works with such a centralizing component IOTA doesn't need that it's delusional to say that IOTA wouldn't have any such centralization but maybe we get better than just a handselected nodes📷 📷 Phantom3D어제 오후 11:52 How would this affect a regular hodler without a node. Should i keep my tokens elsewere to generate mana and put the tokens to use? 📷 Hans Moog [IF]어제 오후 11:53 you can do whatever you want with your mana just make an account at a node you regularly use and use it to build up a reputation with that node to be able to use your funds for free or run a node yourself or rent it out to companies if you just hodl 📷 semibaron어제 오후 11:54 Will there be a build-in function into the node software / wallet to delegate ("sell") my mana? 📷 Hans Moog [IF]어제 오후 11:55 u/semibaronnot from the start - that would happen on a 2nd layer ------------------------------------------------------------------------------------------------------------ 📷 dom어제 오후 9:49
suddenly be incentive to hold iota?
to generate Mana 📷 Hyperware오늘 오전 4:21 The only thing I can really do, is believe that the IF have smart answers and are still building the best solutions they can for the sake of the vision 📷 dom오늘 오전 4:43 100% - which is why we're spending so much effort to communicate it more clearly now we'll do an AMA on this topic very soon 📷 M [s2]오늘 오전 4:54 u/dom please accept my question for the AMA: will IOTA remain a permissionless system and if so, how? 📷 dom오늘 오전 4:57 of course it remains permissionless 📷 dom오늘 오전 5:20 what is permissioned about it? is ETH or Bitcoin permissioned because you have to pay a transaction fee in their native token? 📷 Gerrit오늘 오전 5:24 How did your industry partners think about the mana solution and the fact they need to hold the token to ensure network throughput? 📷 dom오늘 오전 5:26 u/Gerritconsidering how the infrastructure, legal and regulatory frameworks are improving around the adoption and usage of crypto-currencies within large companies, I really think that we are introducing this concept exactly at the right time. It should make enterprise partners comfortable in using the permissionless network without much of a hurdle.They can always launch their own network if they want to ... 📷 Gerrit오늘 오전 5:27 Launching their own network can’t be what you want 📷 dom오늘 오전 5:27 exactly but that is what's happening with Ethereum and all the other networks they don't hold Ether tokens either. 📷 Gerrit오늘 오전 5:32 Will be very exciting to see if ongoing regulation will „allow“ companies to invest and hold the tokens. With upcoming custody solutions that would be a fantastic play. 📷 Hans Moog [IF]오늘 오전 5:34 It's still possible to send transactions even without mana - mana is only used in times of congestion to give the people that have more mana more priority there will still be sharding to keep the network free most of the time 📷 Hans Moog [IF]오늘 오전 5:35 but without a protection mechanism, somebody could just spam a lot of bullshit and you could break the network(수정됨) you need some form of protection from this 📷 M [s2]오늘 오전 5:36 u/HansMoog [IF]so when I have 0 Mana, I can still send transactions? This is actually the point where it got strange... 📷 Hans Moog [IF]오늘 오전 5:37 yes you can unless the network is close to its processing capabilities / being attacked by spammers then the nodes will favor the mana holders 📷 Hans Moog [IF]오늘 오전 5:37 but having mana is not a requirement for many years to come currently even people having fpgas can't spam that many tps and we will also have sharding implemented by then 📷 M [s2]오늘 오전 5:39 Thank youu/HansMoog [IF] ! This is the actually important piece of info! 📷 Basha오늘 오전 5:38 ok, i thought it was communicated that you need at least 1 mana to process a transaction. from the blogpost: "... a node with 0 mana can issue no transactions." maybe they meant during the congestion**, but if that's the case maybe you should add that** 📷 Hans Moog [IF]오늘 오전 5:42 its under the point "Congestion control:" yeah this only applies to spam attacks network not overloaded = no mana needed 📷 Hans Moog [IF]오늘 오전 5:43 if congested => favor txs from people who have the most skin in the game but sharding will try to keep the network non-congested most of the time - but there might be short periods of time where an attacker might bring the network close to its limits and of course its going to take a while to add this, so we need a protection mechanism till sharding is supported(수정됨) 📷 Hans Moog [IF]오늘 오전 6:36 I don't have a particular problem with EOS or their amount of validators - the reason why I think blockchain is inferior has really nothing to do with the way you do sybil protection and with validators I mean "voting nodes" I mean even bitcoin has less mining pools and you could compare mining pools to dpos in some sense where people assign their weight (in that case hashing power) to the corresponding mining pools so EOS is definitely not less decentralized than any other tech but having more identities having weight in the decision process definitely makes it harder to corrupt a reasonable fraction of the system and makes it easier to shard so its desirable to have this property(수정됨) ------------------------------------------------- 📷 Antonio Nardella [IF]오늘 오전 3:36
u/C3PO[92% Cooless]They could also add more git repos instead of the wallet one, and we would probably be #1 there too.. ---------------------------------------------------------------------------------- Disclaimer: I'm sorry, maybe I'm fueling some confusion through posting this mana-thing too soon, but, instead of erasing this posting, I'm adding recent convos. Certain things about mana seem to be not clear, yet. It would be better to wait for some official clarification. But, I hope the community gives its full support to IF, 'cause there could be always some bumps along the untouched, unchartered way. -------------------------------------------------------------------------------------- Recent Addition;
Billy Sanders [IF]오늘 오후 1:36
It's still possible to send transactions even without mana - mana is only used in times of congestion to give the people that have more mana more priority
u/HansMoog [IF] Im sorry Hans, but this is false in the current congestion control algorithm. No mana = no transactions. To be honest, we havent really tried to make it work so that you can sent transactions with no mana during ties with no congestion, but I dont see how you can enable this and still maintain the sybil protection required. u/LuigiVigneri [IF] What do you think?📷

Hans Moog [IF]오늘 오후 2:29
When was this decided u/BillySanders [IF] and by whom? Was this discussed at last resum when I wasnt there? The last info that I had was that the congestion control should only kick in when there is congestion?!?***[오후 2:29]***📷 📷 📷📷

Let's sidebar this discussion and return when we have agreement. Dave has the right idea
If there is a cryptocurrency that has acquired popularity close to Bitcoin, then it is Ethereum. It is among the leading crypto-currencies when it comes to market capitalization. Ethereum is not just a cryptocurrency, but it is also a blockchain system that is useful in creating decentralised applications. Since Ethereum Blockchain is used by most companies now, it is gaining popularity among Ethereum miners and developers. Ethereum mining is a great way to make more cash. Benefiting from cryptocurrencies in p is a perfect option. Since many applications for Blockchain depend on Ethereum. Ethereum mining is going to be lucrative, as its price is expected to grow. The Ethereum minimum can be simplified with the use of the best Ethereum software. There are some apps like that on the market, and we've got the seven best for you here. 7 Ethereum 's Best Apps: ETHminer- This is an Ethereum mining application which is supported on Linux , Windows, and Mac. It is also possible to use the Ethash algorithm, luke Ellaisma, Musicoin Ethereum Classic, Metaverse, It is a command-line program that allows you to construct shortcut commands using a Windows cmd / batch file or Linux Bash script. The next software on our list is CGMiner-A, which was published in 2011. It is one of the common choices and has compatibility with GPU, FPGA, and ASIC. It is open-source software and can cause advanced detection of blocks. It is written in C; Ethereum developers are able to save a hash rate without delay using this Ethereum mining programme. On Linux , Windows, and Mac, this program is open. BitMinter- The graphical interface is transparent and it links easily to the Bitminter mining pool. This software was launched in 2011 and has more than 450,000 user accounts registered. The Java Network Launch Protocol (JNLP) is the foundation of its operations. Linux, Windows and Mac are also compatible with this programme. Claymore- This is one of the most powerful mining applications for Ethereum, and without delaying the mining pace, you can scale up the hash rate. You can also mine other cryptocurrencies like Lbry, Pascal, Siacoin, and Decred using this Ethereum mining programme. This software is Linux and Windows compatible and not Mac compatible. WinETH- If you are looking for an Ethereum mining app that is fast and simple to use, then this is the one for you. It is comparable to WinETH, but it has a simpler Interface and a smarter algorithm that makes it easy to use for Ethereum miners. Minergate-It was the first mining app for Ethereum to deliver merged mining. You can use this app to concurrently mine two separate coins without impacting the main coin's hash rate. In addition, this coin will also tell you about the market's most valuable coins. This programme can be used by Ethereum miners to mine other coins, including Zcash, Liteoin, Monero. BFGMiner- This programme is written in C and operates on various Linux, Windows and Mac operating systems. You will mine crypto coins and have both SHA256D and Scrypt on its algorithm. It also offers you total support for tracking. Conclusion- These are some of the popular mining applications for Ethereum that you can use.

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
