The Economics of "ASICs" for RandomX

Regarding RandomX and ASICs, people seem to mis-understand the interaction between hardware/software, the costs of development/manufacture of world class semiconductors, and the economics of ASIC mining.
These on-chip, bare metal processing units that RandomX requires are highly advanced, and required to make chips "smart." An "ASIC" takes simple dumb functions and iterates them on bare silicon, rather than as a software abstraction (a layer higher) on top of the underlying hardware.
There are a few things that RandomX didn't include, meaning that a fully optimized "ASIC" processor could eliminate some unused logic units to make room for the others particular to RandomX. At most, the designers of RandomX estimate a 2x improvement over current CPUs.
2x. That's almost nothing when you consider the economics of what it takes to make one of these things. As someone who spent 5 years as a process engineer in a world class semicon fab, I can tell you the design, testing, manufacture and turnaround time for advanced CPUs is enormous. Nothing like dumb SHA256 ASICs or simple memory chips. You better be gettting a huge return on investment to go to all that trouble.
2x is nothing. Bitcoin ASICs arose because there was something on the order of 1000x speed advantage over GPUs. That's the kind of economics you need to recoup the costs involved. Not to mention that you are still competing against the ever progressing AMD and Intel advancements (and probably ARM and RISC-V soon enough). Bitmain has very little competition. They have the patents and the process for new ASICs.
So no, it's unlikely, for years, that anyone will develop an economically viable "ASIC" (lol) for RandomX.
What we might see are CPU manufacturers use RandomX as a benchmark for their new units, since you will have the promise of a sort of "rebate" by mining Monero. In fact that could be an awesome marketing opportunity for Monero.

Vitalik's response to Tuur

I interlaced everything between Vitalik and Tuur to make it easier to read.
1/ People often ask me why I’m so “against” Ethereum. Why do I go out of my way to point out flaws or make analogies that put it in a bad light?
Intro
2/ First, ETH’s architecture & culture is opposite that of Bitcoin, and yet claims to offer same solutions: decentralization, immutability, SoV, asset issuance, smart contracts, …
Second, ETH is considered a crypto ‘blue chip’, thus colors perception of uninformed newcomers.
Agree! I personally find Ethereum culture far saner, though I am a bit biased :)
3/ I've followed Ethereum since 2014 & feel a responsibility to share my concerns. IMO contrary to its marketing, ETH is at best a science experiment. It’s now valued at $13B, which I think is still too high.
Not an argument
4/ I agree with Ethereum developer Vlad Zamfir that it’s not money, not safe, and not scalable. https://twitter.com/VladZamfistatus/838006311598030848
@VladZamfir Eth isn't money, so there is no monetary policy. There is currently fixed block issuance with an exponential difficulty increase (the bomb).
I'm pretty sure Vlad would say the exact same thing about Bitcoin
5/ To me the first red flag came up when in our weekly hangout we asked the ETH founders about to how they were going to scale the network. (We’re now 4.5 years later, and sharding is still a pipe dream.)
Ethereum's Joe Lubin in June 2014: "anticipate blockchain bloat—working on various sharding ideas". https://www.youtube.com/watch?v=oJG9g0lCPU8&feature=youtu.be&t=36m41s
The core principles have been known for years, the core design for nearly a year, and details for months, with implementations on the way. So sharding is definitely not at the pipe dream stage at this point.
6/ Despite strong optimism that on-chain scaling of Ethereum was around the corner (just another engineering job), this promise hasn’t been delivered on to date.
Sure, sharding is not yet finished. Though more incremental stuff has been going well, eg. uncle rates are at near record lows despite very high chain usage.
7/ Recently, a team of reputable developers decided to peer review a widely anticipated Casper / sharding white paper, concluding that it does not live up to its own claims.
Unmerciful peer review of Vlad Zamfir & co's white paper to scale Ethereum: "the authors do NOT prove that the CBC Casper family of protocols is Byzantine fault tolerant in either practice or theory".
That review was off the mark in many ways, eg. see https://twitter.com/technocrypto/status/1071111404340604929, and by the way CBC is not even a prerequisite for Serenity
8/ On the 2nd layer front, devs are now trying to scale Ethereum via scale via state channels (ETH’s version of Lightning), but it is unclear whether main-chain issued ERC20 type tokens will be portable to this environment.
Umm... you can definitely use Raiden with arbitrary ERC20s. That's why the interface currently uses WETH (the ERC20-fied version of ether) and not ETH
9/ Compare this to how the Bitcoin Lightning Network project evolved:
elizabeth stark @starkness: For lnd: First public code released: January 2016 Alpha: January 2017 Beta: March 2018…
Ok
10/ Bitcoin’s Lightning Network is now live, and is growing at rapid clip.
Jameson Lopp @lopp: Lightning Network: January 2018 vs December 2018
Sure, though as far as I understand there's still a low probability of finding routes for nontrivial amounts, and there's capital lockup griefing vectors, and privacy issues.... FWIW I personally never thought lightning is unworkable, it's just a design that inherently runs into ten thousand small issues that will likely take a very long time to get past.
11/ In 2017, more Ethereum scaling buzz was created, this time the panacea was “Plasma”.
@TuurDemeester Buterin & Poon just published a new scaling proposal for Ethereum, "strongly complementary to base-layer PoS and sharding": plasma.io https://twitter.com/VitalikButerin/status/895467347502182401
Yay, Plasma!
12/ However, upon closer examination it was the recycling of some stale ideas, and the project went nowhere:
Peter Todd @peterktodd These ideas were all considered in the Treechains design process, and ultimately rejected as insecure.
Just because Peter Todd rejected something as "insecure" doesn't mean that it is. In general, the ethereum research community is quite convinced that the fundamental Plasma design is fine, and as far as I understand there are formal proofs on the way. The only insecurity that can't be avoided is mass exit vulns, and channel-based systems have those too.
13/ The elephant in the room is the transition to proof-of-stake, an “environmentally friendly” way to secure the chain. (If this was the plan all along, why create a proof-of-work chain first?)
@TuurDemeester "Changing from proof of work to proof of stake changes the economics of the system, all the rules change and it will impact everything."
Umm... we created a proof of work chain first because we did not have a satisfactory proof of stake algo initially?
14/ For the uninitiated, here’s a good write-up that highlights some of the fundamental design problems of proof-of-stake. Like I said, this is science experiment territory.
And here's a set of long arguments from me on why proof of stake is just fine: https://github.com/ethereum/wiki/wiki/Proof-of-Stake-FAQ. For a more philosophical piece, see https://medium.com/@VitalikButerin/a-proof-of-stake-design-philosophy-506585978d51
15/ Also check out this thread about how Proof of Stake blockchains require subjectivity (i.e. a trusted third party) to achieve consensus: https://forum.blockstack.org/t/pos-blockchains-require-subjectivity-to-reach-consensus/762?u=muneeb … and this thread on Bitcoin: https://www.reddit.com/Bitcoin/comments/59t48m/proofofstake_question/
Yes, we know about weak subjectivity, see https://blog.ethereum.org/2014/11/25/proof-stake-learned-love-weak-subjectivity/. It's really not that bad, especially given that users need to update their clients once in a while anyway, oh and by the way even if the weak subjectivity assumption is broken an attacker still needs to gather up that pile of old keys making up 51% of the stake. And also to defend against that there's Universal Hash Time.
16/ Keep in mind that Proof of Stake (PoS) is not a new concept at all. Proof-of-Work actually was one of the big innovations that made Bitcoin possible, after PoS was deemed impractical because of censorship vulnerability.
@TuurDemeester TIL Proof-of-stake based private currency designs date at least back to 1998. https://medium.com/swlh/the-untold-history-of-bitcoin-enter-the-cypherpunks-f764dee962a1
Oh I definitely agree that proof of work was superior for bootstrap, and I liked it back then especially because it actually managed to be reasonably egalitarian around 2009-2012 before ASICs fully took over. But at the present time it doesn't really have that nice attribute.
17/ Over the years, this has become a pattern in Ethereum’s culture: recycling old ideas while not properly referring to past research and having poor peer review standards. This is not how science progresses.Tuur Demeester added,
[email protected] has been repeatedly accused of /criticised for not crediting prior art. Once again with plasma: https://twitter.com/DamelonBCWS/status/895643582278782976
I try to credit people whenever I can; half my blog and ethresear.ch posts have a "special thanks" section right at the top. Sometimes we end up re-inventing stuff, and sometimes we end up hearing about stuff, forgetting it, and later re-inventing it; that's life as an autodidact. And if you feel you've been unfairly not credited for something, always feel free to comment, people have done this and I've edited.
18/ One of my big concerns is that sophistry and marketing hype is a serious part of Ethereum’s success so far, and that overly inflated expectations have lead to an inflated market cap.
Ok, go on.
19/ Let’s illustrate with an example.
...
20/ A few days ago, I shared a critical tweet that made the argument that Ethereum’s value proposition is in essence utopian.
@TuurDemeester Ethereum-ism sounds a bit like Marxism to me:
  • What works today (PoW) is 'just a phase', the ideal & unproven future is to come: Proof-of-Stake.…
...
21/ I was very serious about my criticism. In fact, each one of the three points addressed what Vitalik Buterin has described as “unique value propositions of Ethereum proper”. https://www.reddit.com/ethereum/comments/5jk3he/how_to_prevent_the_cannibalism_of_ethereum_into/dbgujr8/
...
22/ My first point, about Ethereum developers rejecting Proof-of-Work, has been illustrated many times over By Vitalik and others. (See earlier in this tweetstorm for more about how PoS is unproven.)
Vitalik Non-giver of Ether @VitalikButerin: I don't believe in proof of work!
See above for links as to why I think proof of stake is great.
23/ My second point addresses Ethereum’s romance with the vague and dangerous notion of ‘social consensus’, where disruptive hard-forks are used to ‘upgrade’ or ‘optimize’ the system, which inevitably leads to increased centralization. More here:
See my rebuttal to Tuur's rebuttal :)
24/ My third point addresses PoS’ promise of perpetual income to ETHizens. Vitalik is no stranger to embracing free lunch ideas, e.g. during his 2014 ETH announcement speech, where he described a coin with a 20% inflation tax as having “no cost” to users.
Yeah, I haven't really emphasized perpetual income to stakers as a selling point in years. I actually favor rewards being as low as possible while still being high enough for security.
25/ In his response to my tweet, Vitalik adopted my format to “play the same game” in criticizing Bitcoin. My criticisms weren't addressed, and his response was riddled with errors. Yet his followers gave it +1,000 upvotes!
Vitalik Non-giver of Ether @VitalikButerin: - What works today (L1) is just a phase, ideal and unproven future (usable L2) is to come - Utopian concept of progress: we're already so confident we're finished we ain't needin no hard forks…
Ok, let's hear about what the errors are...
26/ Rebuttal: - BTC layer 1 is not “just a phase”, it always will be its definitive bedrock for transaction settlement. - Soft forking digital protocols has been the norm for over 3 decades—hard-forks are the deviation! - Satoshi never suggested hyperbitcoinization as a goal.
Sure, but (i) the use of layer 1 for consumer payments is definitely, in bitcoin ideology, "just a phase", (ii) I don't think you can make analogies between consensus protocols and other kinds of protocols, and between soft forking consensus protocols and protocol changes in other protocols, that easily, (iii) plenty of people do believe that hyperbitcoinization as a goal. Oh by the way: https://twitter.com/tuurdemeestestatus/545993119599460353
27/ This kind of sophistry is exhausting and completely counter-productive, but it can be very convincing for an uninformed retail public.
Ok, go on.
28/ Let me share a few more inconvenient truths.
...
29/ In order to “guarantee” the transition to PoS’ utopia of perpetual income (staking coins earns interest), a “difficulty bomb” was embedded in the protocol, which supposedly would force miners to accept the transition.
The intended goal of the difficulty bomb was to prevent the protocol from ossifying, by ensuring that it has to hard fork eventually to reset the difficulty bomb, at which point the status quo bias in favor of not changing other protocol rules at the same time would be weaker. Though forcing a switch to PoS was definitely a key goal.
30/ Of course, nothing came of this, because anything in the ETH protocol can be hard-forked away. Another broken promise.
Tuur Demeester @TuurDemeester: Looks like another Ethereum hard-fork is going to remove the "Ice Age" (difficulty increase meant to incentivize transition to PoS). https://www.cryptocompare.com/coins/guides/what-is-the-ethereum-ice-age/
How is that a broken promise? There was no social contract to only replace the difficulty-bombed protocol with a PoS chain.
31/ Another idea that was marketed heavily early on, was that with ETH you could program smart contract as easily as javascript applications.
Tuur Demeester @TuurDemeester: I forgot, but in 2014 Ethereum was quite literally described as "Javascript-on-the-blockchain"
Agree that was over-optimistic, though the part of the metaphor that's problematic is the "be done with complex apps in a couple hours" part, NOT the "general-purpose languages are great" part.
32/ This was criticized by P2P & OS developers as a reckless notion, given that every smart contracts is actually a “de novo cryptographic protocol”. In other words, it’s playing with fire. https://bitcointalk.org/index.php?topic=1427885.msg14601127#msg14601127
See above
33/ The modular approach to Bitcoin seems to be much better at compartmentalizing risk, and thus reducing attack surfaces. I’ve written about modular scaling here...
To be fair, risk is reduced because Bitcoin does less.
34/ Another huge issue that Ethereum has is with scaling. By putting “everything on the blockchain” (which stores everything forever) and dubbing it “the world computer”, you are going to end up with a very slow and clogged up system.
Christopher Allen @ChristopherA: AWS cost: $0.000000066 for calc, Ethereum: $26.55. This is about 400 million times as expensive. World computer? https://hackernoon.com/ether-purchase-power-df40a38c5a2f
We never advocated "putting everything on the blockchain". The phrase "world computer" was never meant to be interpreted as "everyone's personal desktop", but rather as a common platform specifically for the parts of applications that require consensus on shared state. As evidence of this, notice how Whisper and Swarm were part of the vision as complements to Ethereum right from the start.
35/ By now the Ethereum bloat is so bad that cheaply running an individual node is practically impossible for a lay person. ETH developers are also imploring people to not deploy more smart contract apps on its blockchain.
Tuur Demeester @TuurDemeester: But... deploying d-apps on the "Ethereum Virtual Machine" is exactly what everyone was encouraged to do for the past 4 years. Looks like on-chain scaling wasn't such a great idea after all.
Umm.... I just spun up a node from scratch last week. On a consumer laptop.
36/ As a result, and despite the claims that running a node in “warp” mode is easy and as good as a full node, Ethereum is becoming increasingly centralized.
@TuurDemeester Finally a media article touching on the elephant in the room: Ethereum has become highly centralized. #infura https://www.coindesk.com/the-race-is-on-to-replace-ethereums-most-centralized-layeamp?__twitter_impression=true
See above
37/ Another hollow claim: in 2016, Ethereum was promoted as being censorship resistant…
Tuur Demeester @TuurDemeester: Pre TheDAO #Ethereum presentation: "uncensorable, code is law, bottom up". http://ow.ly/qW49302Pp92
Yes, the DAO fork did violate the notion of absolute immutability. However, the "forking the DAO will lead to doom and gloom" crowd was very wrong in one key way: it did NOT work as a precedent justifying all sorts of further state interventions. The community clearly drew a line in the sand by firmly rejecting EIP 867, and EIP 999 seems to now also be going nowhere. So it seems like there's some evidence that the social contract of "moderately but not infinitely strong immutability" actually can be stable.
38/ Yet later that year, after only 6% of ETH holders had cast a vote, ETH core devs decided to endorse a hard-fork that clawed back the funds from a smart contract that held 4.5% of all ETH in circulation. More here: ...
See above
39/ Other potential signs of centralization: Vitalik Buterin signing a deal with a Russian government institution, and ETH core developers experimenting with semi-closed meetings: https://twitter.com/coindesk/status/902892844955860993 …,
Hudson Jameson @hudsonjameson: The "semi-closed" Ethereum 1.x meeting from last Friday was an experiment. The All Core Dev meeting this Friday will be recorded as usual.
Suppose I were to tomorrow sign up to work directly for Kim Jong Un. What concretely would happen to the Ethereum protocol? I suspect very little; I am mostly involved in the Serenity work, and the other researchers have proven very capable of both pushing the spec forward even without me and catching any mistakes with my work. So I don't think any argument involving me applies. And we ended up deciding not to do more semi-closed meetings.
40/ Another red flag to me is the apparent lack of relevant expertise in the ETH development community. (Check the responses…)
Tuur Demeester @TuurDemeester: Often heard: "but Ethereum also has world class engineers working on the protocol". Please name names and relevant pedigree so I can follow and learn. https://twitter.com/TuurDemeestestatus/963029019447955461
I personally am confident in the talents of our core researchers, and our community of academic partners. Most recently the latter group includes people from Starkware, Stanford CBR, IC3, and other groups.
41/ For a while, Microsoft veteran Lucius Meredith was mentioned as playing an important role in ETH scaling, but now he is likely distracted by the failure of his ETH scaling company RChain. https://blog.ethereum.org/2015/12/24/understanding-serenity-part-i-abstraction/
I have no idea who described Lucius Meredith's work as being important for the Serenity roadmap.... oh and by the way, RChain is NOT an "Ethereum scaling company"
42/ Perhaps the recently added Gandalf of Ethereum, with his “Fellowship of Ethereum Magicians” [sic] can save the day, but imo that seems unlikely...
Honestly, I don't see why Ethereum Gandalf needs to save the day, because I don't see what is in danger and needs to be saved...
43/ This is becoming a long tweetstorm, so let’s wrap up with a few closing comments.
Yay!
44/ Do I have a conflict of interest? ETH is a publicly available asset with no real barriers to entry, so I could easily get a stake. Also, having met Vitalik & other ETH founders several times in 2013-’14, it would have been doable for me to become part of the in-crowd.
Agree there. And BTW I generally think financial conflicts of interest are somewhat overrated; social conflicts/tribal biases are the bigger problem much of the time. Though those two kinds of misalignments do frequently overlap and reinforce each other so they're difficult to fully disentangle.
45/ Actually, I was initially excited about Ethereum’s smart contract work - this was before one of its many pivots.
Tuur Demeester @TuurDemeester: Ethereum is probably the first programming language I will teach myself - who wouldn't want the ability to program smart BTC contracts?
Ethereum was never about "smart BTC contracts"..... even "Ethereum as a Mastercoin-style meta-protocol" was intended to be built on top of Primecoin.
46/ Also, I have done my share of soul searching about whether I could be suffering from survivor’s bias.
@TuurDemeester I just published “I’m not worried about Bitcoin Unlimited, but I am losing sleep over Ethereum” https://medium.com/p/im-not-worried-about-bitcoin-unlimited-but-i-am-losing-sleep-over-ethereum-b5251c54e66d
Ok, good.
47/ Here’s why Ethereum is dubious to me: rather than creating an open source project & testnet to work on these interesting computer science problems, its founders instead did a securities offering, involving many thousands of clueless retail investors.
What do you mean "instead of"? We did create an open source project and testnet! Whether or not ETH is a security is a legal question; seems like SEC people agree it's not: https://www.cnbc.com/2018/06/14/bitcoin-and-ethereum-are-not-securities-but-some-cryptocurrencies-may-be-sec-official-says.html
48/ Investing in the Ethereum ICO was akin to buying shares in a startup that had “invent time travel” as part of its business plan. Imo it was a reckless security offering, and it set the tone for the terrible capital misallocation of the 2017 ICO boom.
Nothing in the ethereum roadmap requires time-travel-like technical advancements or anything remotely close to that. Proof: we basically have all the fundamental technical advancements we need at this point.
49/ In my view, Ethereum is the Yahoo of our day - an unscalable “blue chip” cryptocurrency:
Tuur Demeester @TuurDemeester: 1/ The DotCom bubble shows that the market isn't very good at valuing early stage technology. I'll use Google vs. Yahoo to illustrate.
Got it.
50/ I’ll close with a few words from Gregory Maxwell from 2016,: https://bitcointalk.org/index.php?topic=1427885.msg14601127#msg14601127
See my rebuttal to Greg from 2 years ago: https://www.reddit.com/ethereum/comments/4g1bh6/greg_maxwells_critique_of_ethereum_blockchains/

Ravencoin Multimillion Investment Revealed: Overstock CEO and bitcoin pioneer explains his long-standing crypto play and his philosophy on life

Script:
Byrne:Well I'm not really interested in cryptocurrencies per se. Although in general, I guess there's nothing wrong with me saying there is an open-source project of which I'm really letting something big out of the bag here. I'll tell you. But there's an open-sourceproject called Ravencoin, which Overstock has put millions of dollars into teams. We have people contributing to this open-source project. We think this coin actually has quite a future. It's about - it's bitcoin, but a thousand times more energy efficient. And there's other real interesting virtues to it - so Ravencoin. But other than that , I stay out of the cryptocurrency game. I'm building the - we're focusing on applications of this technology and not just betting on coins themselves.
Silverstein:And is that the primary purpose of Ravencoin is to be a more energy efficient version of some of these other cryptocurrencies?
Byrne:That's - I'd say that's the first feature it brings to the world. What I hear - from the open-source community and on the message boards - I know what they are working on and it seems - it's really quite a - I think it has - it was launched January 3 and it's as this open-source project . And I think it has more - last I heard - the number of miners who are now working on it - or it has spread faster than any number of miners of any coin introduced. It's really quite a phenomenon this Ravencoin. So - and what's nice it's democratized. Yeah, it - what happens is, you know, all these coins like bitcoin and such are built on - there's a processor that's solving mathematical problems. And it's possible to build chips that specialize in just that problem. And so you really can't - with your home computer, you're not going to mine any bitcoin anymore unless you have this dedicated ASIC chip. Well, Ravencoin was designed, so you can't do that - it's ASIC resistant. And that's because the problem that you solve keeps flipping randomly among a bunch of class of problems. Anyway, you can't solve it efficiently with an ASIC's chip, which means it redemocratizes mining. Anyone can download this software, and you don't have an advantage by having this big mining warehouse in China.

Halong Mining - Announcing the most efficient Bitcoin miner in the world.

Highlighting is my own:

Announcing the DragonMint miner series

The DragonMint 16T miner is the world’s most efficient Bitcoin miner, running faster and cooler than any competing miners. It’s the culmination of over 12 months research and development which has resulted in major advancements in mining technology including a brand new generation of ASIC mining chips. The DM8575 ASIC runs at a staggering 85GH per chip with power efficiency of around 0.075J/GH.
The DragonMint miner is the first step in a long strategy, which started in December 2016, to bring much needed competition and innovation to the Bitcoin mining arena. Over 100 world class experts and leaders in their respective fields have been contributing to and working on the project, including chip designers, electronics hardware specialists, and software designers. The project is motivated by, and driven to help facilitate greater decentralisation in Bitcoin mining at all levels, and make sha256 great again.
Now that we have finished the major prototyping and small run batch zero, we are ready to move onto mass production. This is the first stage of rollout, and simultaneously, relationships are being built with other channels to bring a wide variety of products based on the new ASIC chips.
Unlike many other mining projects, the DragonMint is not a design based on simulations. Around $30 million dollars have already been spent on research, development and prototyping miners, writing software and producing small batches of silicon wafers. The time, complexity and cost cannot be underestimated. The next step is mass production. Producing miners from scratch takes around 4 months including manufacturing the silicon chips. We are taking preorders for the next generation miner for delivery starting in March 2018.
We would like to see other Bitcoin mining hardware manufacturers compete equally although it is currently quite challenging due to both heavy competition and prohibitive startup costs. One of the ways we can assist is by publishing board designs and software to allow newcomers to iterate on already advanced design. Production of competitive ASIC chips is a whole different level of difficulty, so we believe this can be alleviated by making chips available in bulk to competitors. Bitcoin is inherently collaborative and we believe the incentives are aligned to promote a healthy mining ecosystem that is still profitable for the participants.
All our strengths aside, we recognise that success in this field is an uphill battle and the game is extremely competitive. Because of the time taken to design new technology and bring it to market, time advantage is a key strategy in order to gain a foothold against formidable competition. For this reason we will defer publishing board designs or software (either directly or through partner channels), until we the first batch of miners is near ready for shipping. Because we have considerable costs to recoup, particular details of our process will also not be made available until closer to shipping of the first batches, to give us a better chance of succeeding and being able to drive forward with innovation into the future.
We will publish more details on our blog, on this website and on Twitter @halongmining.

$INTV Integrated Ventures Signs A Multi Year Hosting And Marketing Agreement With PetaWatt Properties, LLC

https://www.otcmarkets.com/stock/INTV/news/Integrated-Ventures-Signs-A-Multi-Year-Hosting-And-Marketing-Agreement-With-PetaWatt-Properties-LLC?id=227523
PHILADELPHIA, PA / ACCESSWIRE / May 8, 2019 / Integrated Ventures Inc (OTCQB: INTV) ("Company") is pleased to announce a signing of a Hosting and Marketing Agreement with PetaWatt Properties, LLC. As result, the previously contemplated transaction to acquire Erie Power, LLC has been terminated, due to (1) need for a significant capital requirements to re-start plant and build out mining infrastructure, (2) up to 6 months time line for launch of mining operations, (3) need for a significant dilution due to the recent stock pricing weakness and (4) company's ability to secure a similar deal, in terms of power cost, without any additional investment.
>The Agreement
On May 7, 2019, Integrated Ventures has signed a three-year Agreement with PetaWatt Properties, LLC, which will allow Integrated Ventures (1) to consolidate and streamline all mining operations (NC, PA and NJ) into one location, (2) to eliminate Company's lease obligations and payroll expense and (3) to lower its power costs by over 50%, thus greatly enhancing mining profitability and long-term viability.
In addition, Integrated Ventures intends to market PW's services to diversify its business by offering hosting and pool services via a la carte packages to third-party miners and market participants.
> Crypto Market Is Coming Back!
Digital currencies are an emerging asset class underpinned by blockchain, a transformational technology with use cases in virtually every industry.
After experiencing historic growth (growing from a $7 billion market cap in January 2016 to a more than $600 billion market cap by late 2017), the cryptocurrency market entered a bear phase.
However, recovery has been strong in recent months, with Bitcoin's value increasing nearly 70% from December 2018 to May 2019.
Growing Institutional interest, a low cost of mining equipment and ROI are key factors for investment at these levels.
> Business Strategy
The company has formulated and plans to execute a 6 step plan, designed to position INTV for the next bull cycle:
  1. Operational Restructuring. To streamline and improve profitability of current operations, the company is switching from warehouse mining to third party hosting model, based on monthly flat fee and resulting in elimination of all major expenses such monthly lease, payroll, etc. All mining equipment (775+ rigs) is scheduled to be connected by May 30th.
  2. Securing Competitive Electricity Rates. By partnering with PetaWatt, Integrated Ventures will secure access to a lowest power pricing structure.
  3. Generating Cash Flow via Hosting & Mining Revenue Share Services. Integrated Ventures intends to generate significant revenue through reselling of hosting and revenue share services.
  4. Locking-In Record Low Hosting Rate. Newly secured Integrated Ventures' access to the most competitive power cost, will allow the company to utilize and market one of the the most competitive hosting rates in the industry, thus driving profitability and demand for long-term hosting contracts.
  5. Implementing All-In-One "Plug-and-Mine" Mining Solution. Integrated Ventures will offer clients an access to best hosting and pool rates for ASIC and GPU miners, creating a "We Work" -style turn-key mining option for miners seeking a fast market entry combined with a cost effective hosting and pool space.
  6. Purchasing Discounted Mining Rigs from Secondary Markets. Integrated Ventures will keep costs low by purchasing equipment on the secondary market, a strategy that was not possible when the market was in its infancy.
> Why Ramp Up Now?
MarketStability: Bitcoin, and the broader crypto market, have been in recovery following a prolonged bear cycle. Bitcoin has risen from a low of $3,200 in December 2018 to roughly $6,000 in early May, 2019. The cryptocurrency sector market cap has risen from roughly $100 billion to $190 billion over the same period.
GreatPoint & Less Competition: The cryptocurrency market's performance in 2019 indicates a reversal has occurred. However, the markets current total value is still less than 1/3rd of its value in January 2018. Additionally, the bear market was responsible for significant miner attrition. Competition has eased, creating greater profits for those still mining.
>Revenue Opportunity
Integrated Ventures will grow and earn revenues as follows:
>Summary
Integrated Ventures will have reliable long-term access to inexpensive electricity through its three-year agreement with PetaWatt. An access to the low cost power is the key that will allow Integrated Ventures to mine far more profitably than most of its North American competitors and provide hosting services at the market's most competitive price point.
Cost certainty, created by uninterrupted access to affordable power, will allow Integrated Ventures to incorporate all of the above strategies into our business model.
The model allows Integrated Ventures to weather market downturns better than its competitors, while also positioning the company to earn significantly higher returns than its competitors during bull cycles.
Finally, Integrated Ventures will operate and host both ASIC and GPU mining equipment. The importance of this is the flexibility it provides.

[2016 Chinese Article Translated] A Vital Force in the Blockchain World, They Are Developing Something that Will Help an Enterprise Like Alibaba

Hi Vechain Community,
As I said before, I think building a great community together actually matters a lot to ourselves and the hardworking folks at Vechain. So I found an article about Vechain that I thought was fairly well written which has some information that's not here. It's mostly about the early history of Vechain. The title includes Alibaba but don't be misguided they are not partners. I've just carried it from the original. Please point out and provide feedbacks to what other translations you would like to see. I'm not a journalists nor an excellent writer. But I'm happy to help.
Source: *https://www.leiphone.com/news/201610/FkCHnvT80RSIGSgG.html *Time: 2016-10-21 18:56
Vechain is a Shanghai-based company, focusing on solving the counterfeit problems for luxury goods, they are currently focusing on providing a supply chain solution which can prove a source of authenticity for products in the real world. Users can easily find out about the information and the history of products through Vechain.
The Beginning of the Story
Every story starts with an ideology, and this ideology is pursued with romantic heroism.
CEO of BitSE and Vechain, Chandler Jun, has been working in blockchain industry for about 3 years, He’s spent 12 years in IBM and in his own words, “I’ve never thought about leaving, until the moment I saw blockchain.”
CTO, Shuai Chu, to this date has become a renown figure in the blockchain community, has received his PHD in Computer Science from Chinese Academy of Sciences. In 2013, He left Alibaba due to his first encounter with bitcoin. Now he’s accumulated 5 years of blockchain R&D under his belt.
After 7 months of working as a CTO in Louis Vuitton, Sunny Lu left his jobs and joined the other two idol-level friends to start Vechain, taking on COO of Vechain (now CEO). At the time, many friends and business partners came up to him and challenged him, “Why are you leaving your jobs for some gaming coins?” — in 2017, Sunny Lu received a promotional e-mail from Bitcoin, in the beginning, he was simply wondering the difference between bitcoin and QQ coin, but then he embarks on a journey of cryptography, mathematics and his own business, with no intention of looking back.
No one can fight against the time, the futurologists say people overestimate what the future is going to be, but also do not underestimate what could happen in a short span of 3 years. The question to Sunny was, how can they take on this groundbreaking technology, along with their ideologies for the a better world, to implement the changes in reality.
The Recruitment of Blockchain Army
In the Anding district of Shanghai, sits an old building that catches no one’s eye, is where BitSe (Vechain’s parent company) located. If you walk up to the office, you will meet a bunch of world class engineers who graduated from Colombia. Just when you enter the door, you can also pet the Allah Chomsky dog who is just hanging in the office.
“Most of our engineers are located in Europe, a few of them in Shanghai, and the rest works from home.” says the CTO Shuai Chu, Vechain’s engineers are located from Morocco, Bosnia, Herzegovina, Russia, and Canada. We have meetings in Europe once in a while.
“There are just not enough blockchain talents here in China. Also, people who have the knowledge of traditional industry are just too hard to find! We had to recruit globally through the Internet.” says Sunny Lu. Recruitment was a very difficult period. In the beginning, “As long as you understand Blockchain. I will hire you!”, “But now we are recruiting much more specifically, we want people who understand smart contract and have certain domain industry.”
It was a period of barrenness, all we had was imagination and vision.
Many of the angel investors from Uber and Airbnb were asking: “Why did this people join you?” Sunny Lu answers: “I think engineers are the same as business people, they only join the people who they respect, and they also crave for respect from their employers. The best only want to work with the best. For example, one of the Canadian engineer on the tam, is a very well-respected engineer in the field.”
Despite such common sense, it was still a difficult time since Europe’s blockchain development is behind the world by a year. “What the Europeans were talking about now is something we used to talked about a year ago.” says Sunny. However, we were able to overcome such obstacles and Vechain’s competitive advantage comes from being use case focused. We focus on industry adoption, not mathematical theories and technical development. We are already collaborating with PwC, fashion brand like BabyGhost, and airline logistic companies, signing deals in which we provide BAAS (Blockchain as a Service).
Mining, Currency Speculation, and Applications
In 2014 September, Silicon Valley and Wall street was going crazy with FinTech, and Blockchain’s waves were also starting to rise at the time.
Ever since Blockchain became popular in 2015, according to statistics, there are 60 industries trying to explore and understand how they should navigate blockchain, attracting more than 10 billions dollars of investment. People call it the next Internet, with a high probability to reconstruct and improve the current world structure.
In 2013, BitSe enters the field of Cryptography, “We started with mining services for bitcoin, we’ve started designing chips (ASIC), mining pools, and some blockchain browser services.” says Chandlers Jun.
In the blockchain industry, the majority of the people only care about price speculation and mining, no one really cares about technology development. Our voices were not heard in the crowd at the time.
“But have you ever thought about the low level development will be getting so much attention as of today?” asked the reporter.
“I actually have, bitcoin’s design philosophy is very cleverly thought. But I bet most of the people did not see this coming.” Says Chandler Jun. We can see Chandler’s high involvement in cryptocurrency from the 10,000 blog posts he has written, and the manual “Building Yourself from 0 to 1 in Blockchain” he has published.
“Starting in 2015, we have attempted many use cases and directions of blockchain, including ICOs, gaming, distributed web, and we’ve even helped non-profit organization to record their cashflows on blockchain ledgers. But right now, we’ve decided to focus on Vechain, an enterprise solution platform.” says Chandler Jun. “Why do you focus on the supply chain industry while blockchain’s value is initially discovered in Finance?” Reporter asked. “Regulations are very slow and heavy in the finance industry, we’ve made several attempts. But the cost of failure is too high. We’ve chosen an industry with less regulatory risks to start with and we’ve identify very practical use cases of blockchain. So this is where we decided to start.”
‘’And of course, we had to work with our resource constraint.” says Sunny Lu, whose fashion industry background highly influence the homepage of Vechain.
When recalling how they got involved in the fashion industry, Sunny Lu says “In 2015, they have organized a 2 day workshop with many executives from the high-end brands to educate them about blockchain and also to understand what’s their current predicament due to technical constraint. We then reached consensus that blockchain can help solving the counterfeiting problem as well as building a better customer relationship and feedback loop.”
“The brands and the manufacturers care the most about their buyers. But their problems are, the sold products are currently like the spilled water. You have no idea where and who your customers are, and you can’t establish a communication channel. When someone brought an LV, Channel, or Hermes bags, the customers are not able to tell you whether the bag is fake. No one can tell you, no services is provided right now.” says Chandler Jun.
“Due to the lack of data, the upstream and the downstream can’t coordinate and work together. But with blockchain, every luxury item can have an immutable identity, everyone in the world can understand the item by accessing its history, including quality management process, its fabrics, manufactures, and many more. We believe this is a much better experiences of buying a high-end product. However, we never expect there to be no fakes on the market. It’s impossible”. says Chandler Jun.
Horse Speed
It’s hard to not think about Alibaba when we talk about fakes. “Alibaba has been explore blockchain, I’ve even talked to someone who works there, but we are too small now, we need to focus on making our products great at this moment.” says Chandler Jun. “I think the most challenging part is timing, we need to be fast. There is no competitor now, but we still need to run as fast as we can.”
Besides counterfeiting, Vechain also is exploring resource management and large scale supply chain solution. There are so many stories of Vechain that we can talk about, but right now the focus is to expand the scale of the products. All the engineers and business partners are working as hard as they can on a daily basis, so such technology can become a reality and a real world application.

Difficult to fundraise $3 000? Let's collect easily $5 000 000 a year! DOGECOIN 2.0 ideation.

Decentralization and democratization.
Doge 4 Family House fundraising is struggling to raise Ð1,500,000. Where the heck are 110,000,000,000 dogecoins? Fundraiser asks for only 1 dogecoin in 73333. What is going wrong? As of today, yearly mined dogecoins are worth around 5 million USD! Why so difficult to gather just $3 thousand?
I've joined dogecoin community around half a year after dogecoins' birth, i.e. it was too late to mine with a home computer as asics were coming into the market. Asics and merged mining with litecoin centralized dogecoin and took away a lot of fun from average shibies and reserved this space for rather rich people or mining enterprises, huge warehouses filled with electronic equipment doing nothing important for humanity - wasteful calculations. What are asics? They are specialized chips able to quickly solve a very narrow class of problems. Apart of mining, asics designed for mining can only be used as heaters or collectibles. While mining, they solve meaningless problems. There is no use of these computations apart of creating dogecoins, litecoins or bitcoins. Daily electricity usage (only bitcoin network) exceeds 1 million USD daily. The cost of equipment to match bitcoin network hashrate I have estimated to cost currently between 100 and 500 million USD. If dogecoin would be valued close to 1Ð = 1$, dogecoin mining network would be as costly and seeping as much electricity. All these money and resources for garbage calculations. This is basically wrong.
As I was unable to mine, I have bought some dogecoins on the market. I won some in design competitions here on reddit/dogecoin, I tipped and I've been tipped quite a lot. I gave up tobacco in favour of electric cigs and doing other similar savings and altogether I have collected close to one million dogecoins. Well, over 90 000 left in dogetipbot were burnt in 'Wow Such Business' by Mohland, some disappeared on some websites that... disappeared. My bad.
Last month I decided to review my 'investments'. I have sold most of my dogecoins I had left in my wallet and Shibe Poker site and bought some other coins, especially gridcoins. As an investment - I could point to some other coins that seem to have higher potential to bring a good return. But I like Gridcoin Research. This coin is based on mixed Proof of Stake and Proof of Research. The latter one is basically a variant of Proof of Work. Now it's almost a week since I've started mining cryptocurrency for the first time in my life! And it's quite exciting. Preliminary estimations show that I won't make any good return on mining gridcoin. Electricity here is expensive. Buying and holding - if it would take off 'to the moon' one day - would be much more profitable. Return will roughly cover only mining electricity costs (or not fully), at least in my case. But! But I like it! I can be a part of the system, unlike in dogecoin nowadays. I take part in scientific research. Years ago I had a special screensaver and my AMD Athlon desktop was crunching numbers for [email protected] project. Now I can continue this project or start any other ranging from mathematical problems to mapping new territories in our bodies, from discovering the shape of our Milky Way to finding cures for illnesses. While Dogecoin is aiming for the Moon, Gridcoin is reaching far further away (from asteroids, through Milky Way to distant galaxies) and far closer (researching our own genome, gut bacteria, Zika cure, treatment for common childhood cancers). Mining power of our home computers that is meaningful for humanity. Which is Wow? Much amaze? So science!

DOGECOIN 2.0

Here goes my proposal for DOGECOIN 2.0. It's only ideation, I know it would need a huge amount of work and it would be difficult, but first we need a direction and then we can research feasibility.
1) Migration from Proof of Work to Proof of Stake + Proof of Research (or other useful Proof of Work that is non Asic based) = taking new coins from whales only back to community, empowering shibes. Surely, those who are cleverer, working harder, can and want to invest more money will get higher share is rewards. At least their mining rigs would do a meaningful job and average John Doe will be still relevant with his all purpose desktop computer.
2) Reward scheme. There is 5 billion extra supply a year plus mining fees. For simplicity I will assume just for this draft there is 5 billion coins to share but in more detailed plan we should add mining fees, too.
2a) 20% (1 billion Ð ~ 2 million $) for Non Profit. A list of eligible organizations / projects would be proposed, voted and whitelisted. 2b) 1% (50 million Ð ~ 100 thousand $) for DEV fund 2c) 1% (50 million Ð ~ 100 thousand $) for Dogecoin Foundation (marketing, maintaining list of non profit projects and checking those projects - or it could be part of 2a) above 2d) 39% (1.75 billion Ð) for Proof of Stake (interest) 2e) 39% (1.75 billion Ð) for Proof of Work (non Asic - like gridcoins' Proof of Research) (mining) Coins collected as fees should be assigned proportionately or some other way to above funds.
Would dogecoin reach current litecoin market cap, above sums would reach $20 million/year for non profit projects, $1 million/year for development etc. At some point shares could be adjusted.

Inflation

Inflation, or more precisely dogecoin supply growth which is 5 billion a year, or currently less than 5% a year is by some shibes regarded as a brake for market value growth. It was discussed several times.
There seems nothing fundamentally wrong with keeping current supply growth rate as it is.

Note

Due to excellent job devs are doing I have retrieved some coins from dogeparty. Just quote ‘Much Humanity, So Earth, Such Fun’ in your reply to get a tip. Over 1000 dogecoins from my retrieved dogeparty funds are up for grabs!

Hard Fork

Such a huge change could cause a hard fork with both forks alive, i.e. old and new dogecoins would coexist. Is it something to be afraid of? As recent story of Bitcoin and Bitcoin Cash shows, such a scenario is possible, what is more - does not effect badly either new or old fork. Thus I would take it a step further and deliberately leave old dogecoin and start a new one.
Proposed changes would bring back decentralization and democratization and empower community, allow collect easily substantial amounts of money for non profit projects, secure development and potentially put into good use thousands to millions of our home computers. I expect this would lead to greater adoption and rise in value - for those looking to 1Ð = 1$.
If Dogecoin 1.0 was aiming To The Moon, for Dogecoin 2.0 let's aim For Humanity, For Earth, For Fun!

EDIT

Giveaway ended. Final remarks.

All the best!

The Daily: Poloniex Goes Mobile, Cobinhood Adds USD Fiat, Bitmain Expands

The Daily: Poloniex Goes Mobile, Cobinhood Adds USD Fiat, Bitmain Expands
https://preview.redd.it/xlewtbals9a11.jpg?width=1068&format=pjpg&auto=webp&s=65ce66e2affbfcd4ee6b5dd4d2bc304ace2bf8ea
In today’s edition of Bitcoin in Brief we cover a new mobile app from Poloniex, the addition of USD fiat at Cobinhood exchange and the expansion plans of Bitmain in Israel. We also report about a triad boss who claims to have raised $750 million in a recent ICO.
Poloniex Goes Mobile
Circle Internet Financial Ltd., the Goldman Sachs-backed Boston-headquartered company that acquired Poloniex earlier this year, has announced the launch of an official app for the exchange. The team behind the venue wrote on their blog: “In our effort to deliver the best possible experience across all platforms, we’ve acquired the best-in-class Poloniex app for iOS and Android! This app will now be the only officially supported Poloniex app in the App Store and Play Store.” They added that : “We have big plans for this app – next up is better mobile verification!”
https://preview.redd.it/mq21b4gms9a11.jpg?width=696&format=pjpg&auto=webp&s=fb543d53b1ab6bccd89ab4d5ed000d44d4ee09ac
Cobinhood Adds USD Fiat
Taiwan-based cryptocurrency service platform Cobinhood has announced the launch of fiat trading. This means that fiat can be converted through the exchange into cryptocurrencies, and vice versa. U.S. dollar deposits will be accepted from July 20th. The company needed to comply with KYC Level 3 in order to operate in a stringent regulatory environment and partnered with Epay for a solution.
“In several instances, the market is not reflecting tremendous progress being made at cryptocurrencies worldwide,” states Popo Chen, founder of Cobinhood. “Traders know there are opportunities abound for value, so it’s a very synergistic time to debut fiat trading on the Cobinhood platform. There’s no doubt in my mind that many value investors were waiting on the sidelines until prices rationalized, and so the near term promises to be an exciting time for exchanges that can offer the liquidity fiat options provide.”
Bitmain Expands R&D in Israel
Bitmain Technologies Ltd., the Beijing-headquartered bitcoin mining machines (ASIC chips) producer recently valued at $12 billion, plans to seriously expand its research and development center in Israel soon. The company told local newspaper Globes that in the near future it is expected to triple its workforce in the country. Bitmain explained that it would recruit more than 40 researchers, programmers, engineers and marketing personnel to its development center in Ra’anana, which is managed by VP Gadi Glikberg, to be added to the 15 employees there today.
Glikberg commented: “Bitmain had huge momentum in the past year as a result of the ever growing adoption of blockchain technology in general and digital coins in particular. The world is indeed in a relative calm from the great hype of December 2017, but for the big companies in the field it is a golden opportunity to design, build and grow, and Bitmain recognizes the potential of the Israeli knowledge and abilities to contribute to the company’s global efforts.” The roles that the company seeks to fill in Israel include, among others, blockchain researchers, senior security and software engineers, marketing people, Python and Javascript programmers and QA software testers. $750 Million Triad Linked ICO?
According to reports from China, the famous Macau triad boss “Broken Tooth” Wan Kuok-koi has partnered with a Beijing company, which might be backed by the government, to promote chess and poker tournaments in the country. And the company, World Hung Mun Investment, claims that it raised $750 million in less than five minutes in an initial coin offering for its HB token. Wan launched the ICO at an event in Cambodia said to be attended by high-ranking government and military officials, businessmen and Chinese celebrities. The triad boss was previously linked by the New York Times to Dragon Coin, the casino gamblers’ ICO token, and claimed to open a blockchain powered Chinese culture center in Cambodia.

Black Arrow announces delay for Prospero X-1, X-3 and Minion cloud mining orders

Unfortunate news, though props to them for being transparent about the delivery delay:
"We have to inform you that our schedule to manufacture and assemble the system has been disrupted and we are unable to make delivery of the Batch 1 Minion ASIC chip on the initial scheduled date (end of February). We are now expecting to dispatch all Batch 1 orders on 1st of May 2014.
Please be re-assured we are confident that we have tried our best to accomplish our initial ambitious targets. However, we came to the conclusion that it is in the best interest of our customers to delay shipping in order to ensure that the product provides the best-possible user experience.
Without this delay we would have achieved 1.5W/Ghash which would have meant that our chip would not have been competitive at all.
We have now finalized the design process using our newly improved code and will start manufacturing the chip (tape out) in the next few days.
We are happy to announce that Black Arrow Software’s products remain on target for being the best in their class for power consumption. We confirm that our latest improved design has the following technical specifications:
·0.75w/Ghash on TT corner @ 25C which is expected to run at 120Ghash/sec.
·SS corner will be 0.6w/ghash and will run at 100Ghash.
·A further underclocking and underpower should be possible and should yield 80Ghash @ 0.5W/ghash. However, please note that this is not guaranteed to work stable.
Please note, that a further push for improvement in the optimization process would have guaranteed further delays for at least 1-2 months.
It is no secret to us that the Bitcoin mining process is proving to be more and more difficult every day. To compensate our loyal customer for the unforeseen delay of in delivering our miners for batch 1, we are happy to offer free extra hashing power which consists of 25% of your purchased hashing power from our Rent-Some-Minions cloud program for 4 months.
The account for the tape-out has been settled in full and we are confident that the delivery will be completed shortly.
We are taking all the necessary measures and positive actions to expedite delivery to you as soon possible and we are confident that we have the resources to be successful.
Please note:
·We estimate that the delivery for the Batch1 will coincide with the delivery of the Batch2
·The delivery of Batch2 remains unchanged
·The one-off offer presented above is open to the customers who placed orders for Batch1
Sincerely,
The Black Arrow Software Team"
EDIT: I received an e-mail message on 01/31 seemingly agreeing to provide me with a refund if I wanted one, less a $50USD service charge. They also asked me to consider waiting a few more days while BA explores alternatives to the 25% bonus compensation they previously offered. I assume nearly everyone who has complained recently received a similar message.

It is time to usher in a new phase of Bitcoin development - based not on crypto & hashing & networking (that stuff's already done), but based on clever refactorings of datastructures in pursuit of massive and perhaps unlimited new forms of scaling

Debates among devs are normal and important.
Debates between programmers are the epitome of decentralized development and as such they are arguably the most important mechanism that will ensure the ongoing success of the Bitcoin (or cryptocurrencies) project.
Therefore, we would be wise to encourage such debates, rather than trying to make them go away by calling them "personal attacks".
In the real world, there aren't a whole lot of different ways to hammer a nail into a board or pour cement into a hole - but in the abstract world of mathematics and programming, there are many, many different ways to represent and manipulate a data structure, limited only by our imaginations, so it is actually appropriate to expect and even demand lots of jostling and critiquing from our programmers as they "try to invent a better mousetrap."
In fact, this is the kind of informal jockeying and shop talk that always has gone on and always will go on among mathematicians and programmers - and quite rightly so, because it is precisely the mechanism whereby they maintain order among their ranks, by making subtle and cogent observations about who knows what.
A famous example of this typical sort of jockeying and shop talk can be seen elsewhere in the ongoing debates between programmers of the "procedural" / "object-oriented" school (C/C++, Java) versus the "functional" school (Haskell, ML). It's always quite an eye-opener for a procedural programmer who's been using "loops" all their life, when they finally discover how to use an "iterator" in functional programming. They both "accomplish" the same thing of course - but in radically and subtly different ways, since an iterator in a functional language is a "first-class citizen" which can be passed around as an argument parameterizing a function, etc. - allowing much more compact and expressive (and sometimes even more efficient) code.
Different Bitcoin dev skill sets are required for different stages of Bitcoin's life cycle
An example of the debate between various devs can be seen here:
It is "clear that Greg Maxwell actually has a fairly superficial understanding of large swaths of computer science, information theory, physics and mathematics."- Dr. Peter Rizun (managing editor of the journal Ledger)
https://np.reddit.com/btc/comments/3xok2o/it_is_clear_that_greg_maxwell_unullc_actually_has/
What Peter R is saying here is simply that a different skill set is needed to usefully contribute to Bitcoin development now that it has moved well beyond its "proof-of-concept and initial rollout" stages (hey, this thing actually works) and is now trying to move into its "massive scaling" stages (let's try to roll this thing out to millions or billions of people).
Bitcoin's "proof-of-concept and initial rollout" stages
Initially, during the "proof-of-concept and initial rollout" stages, the skill set that was required to be a "Bitcoin dev" merely involved knowing enough cryptography, hashing, networking, "game theory", rudimentary economics, and C/C++ programming in order to be able to understand Satoshi's original vision and implementation, doing some simple and obvious refactorings, cleanups and optimizations while respecting the overall design decisions captured in the original C/C++ code, and maintaining the brilliant "game theory" incentives baked therein - the most notable of all being of course that thing which some mathematicians have taken to calling "Nakamoto Consensus" (which could be seen as a useful emerging mathematical-historical term along the lines of Nash Equilibrium, etc.) - ie, Satoshi's brilliant cobbling-together of several existing concepts from crypto and hashing and game theory and rudimentary economics in order to provide a good-enough solution to the long-standing Byzantine Generals Problem which mathematicians and programmers had heretofore (for decades) considered to be unsolvable.
In particular, during the "proof-of-concept and initial rollout" stages, the crypto and hashing stuff is all pretty much done: the elliptic-curve cryptography has been decided upon (and by the way Satoshi very carefully managed to pick one of the few elliptic curves that is NSA-proof) and the various hashing algorithms (SHA, RIPE) are actually quite old from previous work, and the recipe for combining them all together has been battle-tested and it should work fine for the next few decades or so (assuming that practical quantum computing is probably not going come along on that time scale).
Similar, during the "proof-of-concept and initial rollout" stages, the networking and incentives and game theory are all pretty much done: the way the mempool gets relayed, the way miners race to solve blocks while trying to minimize orphaning, and the incentives provided currently mainly by the coinbase subsidy and to be provided much later (after more halvings and/or more increases in volume and price) mainly by transaction fees - this stuff has also been decided upon, and is working well enough (within the parameters of our existing imperfect regulatory and economic landscape and networking topology, where things such as ASIC chips, cheap electricity and cooling in China, and the Great Firewall of China have come to the fore as major factors driving decisions about who mines where).
Bitcoin's "massive scaling" stages
Now, as we attempt to enter the "massive scaling" stage, a different skill set is required. As I've outlined above, the crypto and the hashing and the incentives are all pretty much done now - and mining has become concentrated where it's most profitable, and we are actually starting to hit the "capacity ceiling" a few times (up till now just some spam attacks and stress tests - but soon, more worryingly, possibly even with the next few months, really hitting the capacity ceiling with "real" transactions).
Early scaling debates centered around blocksize
And so, for the past year, we've gone through the never-ending debates on scaling - most of them focusing up till now (perhaps rather naïvely, some have argued) on the notion of "maximum blocksize", which was set at 1 MB by Satoshi as a temporary anti-spam kludge.
The smallblock proponents have been claiming that pretty much all "scaling solutions" based on simply increasing the maximum blocksize could have bad effects such as decreasing the number of nodes (decreasing this important type of decentralization) or increasing the number of orphans (decreasing profits for certain miners) - so they have been quite adamant in resisting any such proposals.
Meanwhile the bigblock proponents have been claiming that increased adoption (higher price and volume) should be more than enough to eventually offset / counteract any supposed decrease in node count and miner profits that might happen immediately after bigblocks would be rolled out.
For the most part, both sides appear to be arguing in good faith (with the possible exception of private companies hoping to be able to peddle future, for-profit "solutions" to the "problem" of artificially scarce level-one on-chain block space - eg, Blockstream's Lightning Network) - so the battles have raged on, the community has become divided, and investors are becoming hesitant.
New approaches transcending the blocksize debates
In this mathematical-historical context, it is important to understand the fundamental difference in approach taken by Peter__R. He is neither arguing for smallblocks nor for bigblocks nor for a level-2 solution. He is instead (with his recently released groundbreaking paper on Subchains - not to be confused with sidechains or treechains =) sidestepping and transcending those approaches to focus on an entirely different, heretofore largely unexplored approach to the problem - the novel concept of "nested subchains":
By nesting subchains, weak block confirmation times approaching the theoretical limits imposed by speed-of-light constraints would become possible with future technology improvements.
Now, this is a new paper, and it will still undergo a lot of peer review before we can be sure that it can deliver on what it promises. But at first glance, it is very promising - not least of all because it is attacking the whole problem of "scaling" from a new and possibly highly productive angle: not involving bigblocks or smallblocks or bolt-ons (LN) but instead examining the novel possibility of decomposing the monolithic "blocks" being appended to the "chain" into some sort of "substructures" ("subchains"), in the hopes that this may permit some sort of efficiencies and economies at the network relay level.
"Substructural refactoring"-based approaches
So what we are seeing here is essentially a different mathematical technique being applied, for the first time, to a different part of the problem in an attempt to provide a "massive scaling" solution for Bitcoin. (I'm not sure what to call this technique - but the name "substructural refactoring" is the first thing that comes to mind.)
While there had indeed been some sporadic discussions among existing devs along the lines of "weak blocks" and "subchains", this paper from Peter R is apparently the first time that anyone has made a comprehensive attempt to tie all the ideas together in a serious presentation including, in particular, detailed analysis of how subchains would dovetail with infrastructure (bandwidth and processing) constraints and miner incentives in order for this to actually work in practice.
Graphs reminiscent of elasticity and equilibrium graphs from economics
For example, if you skim through the PDF you'll see the kinds of graphs you often see in economics papers involving concepts such as elasticity and equilibrium and optimization (eg, a graph where there's a "gap" between two curves which we're hoping will decrease in size, or another graph where there's a descending curve and an ascending curve which intersect at some presumably optimum point).
Now, you can see from the vagueness of some my arguments and illustrations above that I am by no means an expert in the mathematics and economics involved here, but am instead merely a curious bystander with only a hobbyist's understanding of these complex subjects (although a rather mature one at that, having worked most of my long and chequered career in math and programming and finance).
But I am fairly confident that what we are seeing here is the emergence of a new sort of "skill set" which will be needed from the kind of Bitcoin developers who can lead us to a successful future where millions or billions of people (and perhaps also machines) are able to transact routinely and directly on the blockchain.
And if a developer like Peter R wants to direct some criticism at another developer who has failed to have these insights, I think that is a natural manifestation of human ego and competitiveness which is healthy to keep these guys on their toes.
A new era of Bitcoin development
The time for tweaking the crypto and hashing is long past - which means that the skills of guys like nullc and petertodd may no longer as important as they were in the past. (In fact, there are entirely other objections can be raised against Peter Todd, given his proclivity for proving that he can, at the mathematical level, break systems which actually do work "good enough" by relying on constraints imposed at the "social level" - a level which PTodd evidently does not much believe in. For the most egregious example of this, see his decision to force his Opt-In (soon to become On-By-Default) Full RBF - which breaks existing "good-enough" risk mitigation practices many business had up till now relied on to profitably use zero-conf for retail.)
Likewise the skills of adam3us may also not be as important as they were in the past: he is, after all, the guy who invented ecash, so he is clearly a brilliant cryptographer and pioneer cypherpunk who laid the groundwork for what Bitcoin has become today, but it is unclear whether he now has (or ever had) the vision to appreciate how big (and fast) Bitcoin can become (at "level 1" - ie, directly on the blockchain itself).
In this regard, it is important to point out the serious lack of vision and optimism on the part of nullc and petertodd and adam3us:
TL;DR: Times are a-changin'. The old dev skill sets for Bitcoin's early years (crypto, hashing, networking) are becoming less important, while new dev skill sets are becoming more important (such as something one might call "substructural refactoring"). We should encourage competition as new devs emerge who have these new skill sets, because they may be the way out of the "dead end" of the blocksize-based approaches to scaling, opening up massive and perhaps unlimited new forms of "fractal-like" scaling instead.

[uncensored-r/btc] Halong Mining - Announcing the most efficient Bitcoin miner in the world.

The following post by StopAndDecrypt is being replicated because some comments within the post(but not the post itself) have been openly removed.
The original post can be found(in censored form) at this link:
np.reddit.com/ btc/comments/7eqzzr
The original post's content was as follows:
Highlighting is my own:

Announcing the DragonMint miner series

The DragonMint 16T miner is the world’s most efficient Bitcoin miner, running faster and cooler than any competing miners. It’s the culmination of over 12 months research and development which has resulted in major advancements in mining technology including a brand new generation of ASIC mining chips. The DM8575 ASIC runs at a staggering 85GH per chip with power efficiency of around 0.075J/GH.
The DragonMint miner is the first step in a long strategy, which started in December 2016, to bring much needed competition and innovation to the Bitcoin mining arena. Over 100 world class experts and leaders in their respective fields have been contributing to and working on the project, including chip designers, electronics hardware specialists, and software designers. The project is motivated by, and driven to help facilitate greater decentralisation in Bitcoin mining at all levels, and make sha256 great again.
Now that we have finished the major prototyping and small run batch zero, we are ready to move onto mass production. This is the first stage of rollout, and simultaneously, relationships are being built with other channels to bring a wide variety of products based on the new ASIC chips.
Unlike many other mining projects, the DragonMint is not a design based on simulations. Around $30 million dollars have already been spent on research, development and prototyping miners, writing software and producing small batches of silicon wafers. The time, complexity and cost cannot be underestimated. The next step is mass production. Producing miners from scratch takes around 4 months including manufacturing the silicon chips. We are taking preorders for the next generation miner for delivery starting in March 2018.
We would like to see other Bitcoin mining hardware manufacturers compete equally although it is currently quite challenging due to both heavy competition and prohibitive startup costs. One of the ways we can assist is by publishing board designs and software to allow newcomers to iterate on already advanced design. Production of competitive ASIC chips is a whole different level of difficulty, so we believe this can be alleviated by making chips available in bulk to competitors. Bitcoin is inherently collaborative and we believe the incentives are aligned to promote a healthy mining ecosystem that is still profitable for the participants.
All our strengths aside, we recognise that success in this field is an uphill battle and the game is extremely competitive. Because of the time taken to design new technology and bring it to market, time advantage is a key strategy in order to gain a foothold against formidable competition. For this reason we will defer publishing board designs or software (either directly or through partner channels), until we the first batch of miners is near ready for shipping. Because we have considerable costs to recoup, particular details of our process will also not be made available until closer to shipping of the first batches, to give us a better chance of succeeding and being able to drive forward with innovation into the future.
We will publish more details on our blog, on this website and on Twitter @halongmining.

I've been 'watching' since Bitcoin was created in 2009

I really do feel that bitcoin, as it becomes more and more mainstream, is getting more and more greedy, looking for profit and how to make a quick buck, people involved. I'll be the first to say, it IS MOST CERTAINLY a get rich quick scheme. I mean come on, everyone here "knows" that they had the inside scoop back when they bought at $20. Even more inside knowledge from the 2009 group of miners that had 10,000 BTC laying around for a pizza. They knew they were onto something after that first transaction.
It has, QUITE LITERALLY, amplified people's thousands of dollars into millions, in under 5 years. Why work when you can just sit back and watch your bitcoins "deflate" to what they are REALLY worth if governments weren't making everything so difficult. Even better yet, why work for the "corporate machine" if you can make a few bitcoin helping your elderly neighbor and know it's going to be worth $100,000 5 years later? I'm not saying it's here to promote laziness. It most certainly is NOT here for that reason. On the contrary, I believe it's to unharness "us" from our "money masters" and allow us to prosper and allow freethought to roam the lands. It will allow people to EXPERIMENT, allow people to philosophize and not worry about whether they will have money for bread the next day to do it. It's a hell of a tool to let you relax, the only reason you weren't relaxing in the first place is because the dollar is in a SUPER DUPER inflationary cycle and it's never coming back out.
It's getting to the point I'm starting to fear the worst for bitcoin adoption, however. It's already getting regulated because people didn't steer clear of linking it's value to the US dollar, and if they devise a way to push a law through banning digital currencies, I think it'll be the end. I think the central banks will get their (c)laws into the "peasant; working" class, no matter what, if we do not get this system decentralized like it was intended.
I do not think there was ever supposed to be a method of exchanging USD for Bitcoin. I think that Mt. Gox was a "corporate invention made to profit off of Bitcoin "in the real world"." I think we were SUPPOSED to mine them and integrate them into society with nothing backing them but the miners and the power of the system to begin with. Just this thought alone opens up millions of possibilities to the thought that maybe bitcoin, while making our method of exchange, could also propel our technology into the next generation, when Moore's Law, just isn't keeping up. I mean, look at the processing power of the "supposed" BFL ASICs. That power is insane by today's normal PC standards! Bitcoin is LITERALLY pushing technology forward. I think of it as, "the swift kick in the ass profiteering tech companies needed." People want the most powerful system that can be had so that they can make the most amount of profits whether it's because they want to own all those precious pieces of data or if they want to instantly turn around and be a sell out and go for the US DOLLARS or even better yet, GOLD... yeah, gotta have that gold that you can hold in your hand. Ha! But I digress...
I think that the man who invented this system knew of Nikola Tesla's works VERY well and knows if he can get the profits out of the picture of the people with the money, get the money into the hands of the inventors to do it themselves, PEOPLE WHO CAN INVENT THINGS, WILL DO SO! Also, goes back to the last statement. The incentive to progress technology will bleed over into other areas than bitcoin mining once the 21million are minted. That speed will be translated into MOBILE PHONES! The chips will get smaller. We will be carrying around a 1THz phone in 50 years or less if this currency and protocol make it that long!!!
I think the man knew that if people saved their money and always knew whatever they needed in the future would be less and less over time, that they would lose their greed, see the light, get in contact with their higher selves, WHATEVER YOU BELIEVE, it all fits! If we could conquer this greedy stage of humanity we are in, I think we could see some great things. Imagine using all the power of the nukes in existence to power the most efficient motor we've ever created (all thanks to bitcoin being such a wonderfully sound currency) and then find something that's been right under our noses all this time about existence. Perhaps, the so-called, Philosopher's Stone if you were an alchemist back in the day. Maybe the key to everything is right here in what we look at as "money."
This, "bitcoin" isn't what the world needs. This, "bitcoin" is what the world MUST have. Not to be forced upon anyone, but to be explained, logically and without contorting facts to the people. Those wise enough to lend you an ear, and heed your advise will be well rewarded. In the end, even the people who don't want to adopt, are going to have to. It's going to be by the "force" of the dollar collapsing, though. NOT because of the bitcoin community holding a gun to your head like the agencies that back the currency system currently, do. To sum this all up, basically the greedy people of the world have literally created a money system that they control, they have started corporations to hold their cash and employ the "working class" and I really don't need to be any more specific than that. Just by that logic (which can't be contradicted, unless you want to tell me a small elite don't run the world, in which case, I'd feel sorry for you) you can never be part of the ungreedy, you are greedy. You are greedy in the fact you won't listen to people who have done nothing but study the subjects mentioned above and are now EXCITEDLY telling everyone about. It happened with bitcoin, please remember. You got into bitcoin and then you saw it's potential and then you told EVERYONE. That's all I'm doing. :)
I think the man or team who created Bitcoin actually saw the need for the "Main Street" currency (Bitcoin) to compete with the "Wall Street" currency (Fiat no longer backed by Gold or anything other than other fiat.) I believe that Satoshi Nakamoto had that in his grand design from the very beginning (or hell, maybe he added it at the end when he was checking out how to secure his amazing system to make it work for the real world.) He KNEW that if wall street's greedy fingers got into it, and turned into a selling frenzy at the end just to go back to the system he originally wrote to fight it, it'd go down hill from there. That's the reason for it being deflationary by nature. It defeats the purpose of trying to get rich and allows you to focus more on a humanitarian stance. Maybe I'm crazy, maybe none of the world believes like me. Maybe I'll get a million down votes, but I hope for the humanity of our posterity that I get more ups than downs on this.
EDIT: - Corrected a place I said "dollars," instead of "bitcoin" in the second paragraph - Double spaced to add clarity - Corrected typo from, "in the contrary" to "on the contrary" in the second paragraph - Added quotes around "us" in the second paragraph - Corrected "allow" to "It will allow" in the second paragraph - Screw all the edits. I'm fixing it. Just bear with me. :P

I am going to design an Async ASIC chip for a class project.

Background:
I am enrolled in a VLSI course at a university. At the end of this class we will be manufacturing and testing our very own IC design.
Part of the class is a 5 week, four person team project that is entirely open ended. We have coordinated with a professor who specializes in asynchronous design, and we are planning on making an asynchronous ASIC bitcoin miner. I do not expect to be competitive in the bitcoin mining feild, we are designing this chip as a class project to demonstrate our ability in VLSI design. This is a 600nm process, which is seriously like 1990's technology. This will not be a particularly fast chip, but it might be a little bit faster than a standard CPU if and only if we can implement the SHA algorithm in hardware well enough.
Question:
I know relatively little about bitcoin, I have been subbed here for about three weeks and I have read the wikipedia page on Bitcoin and on the SHA-2 algorithm. I am looking for website resources that explain hardware implementations of SHA-256. I was wondering if anybody could point me towards helpful pages. Additionally, I was wondering if you could provide any other good website resources as starting points for bitcoin mining information, including specific information about the bitcoin mining protocol. When I search I find a lot of forum debates, but no real information. Are there any websites that explain this sort of thing that are common in the bitcoin community? Should I be turning to research papers at my university library to find this?
Specifically, I know we need to implement SHA-256 as part of the bitcoin algorithm. In an 'ASIC' rig, does the SHA-256 hardware exist as a co-processor to a general purpose CPU, or does the ASIC chip directly implement the entire algorithm. Basically, I am completely unaware of the cpu architecture required to implement bitcoin mining, yet that is what I have set out to do, because general purpose CPU's are easy...(ish)... If it is simply a matter of understanding SHA-256 algorithm and implementing my own architecture that is okay but I would rather not reinvent the wheel if I do not have to. An open source verilog FPGA implementation would be a great starting point.
Thanks for your pointers.
