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/Hans Moog [IF] My first thought is that the 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 individual every 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/TangleAccountant yes 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/semibaron not from the start - that would happen on a 2nd layer
------------------------------------------------------------------------------------------------------------

📷
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/Gerrit considering 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/Hans Moog [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 you u/Hans Moog [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)

I'm sorry, maybe I'm fueling some confusion through posting this mana-thing too soon,

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/Hans Moog [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/Luigi Vigneri [IF] What do you think?📷

Ethereum 's Top 7 Mining Tools in 2020

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.

How are FPGAs used in trading?

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

Monero, the Most Private Cryptocurrency

Monero, the Most Private Cryptocurrency
Written by the CoinEx Institution, this series of jocular and easy to understand articles will show you everything you need to know about major cryptocurrencies, making you fully prepared before jumping into crypto!

https://preview.redd.it/ryvcznqspe451.jpg?width=720&format=pjpg&auto=webp&s=5fa91e26288d7b0a624113ed21172cc9fd5624a3
Monero, or XMR for short, is an open-source cryptocurrency that is safe, reliable, private, and untraceable. It can run on Windows, Mac, Linux, and FreeBSD, and is known as one of the most private cryptocurrencies. In 2018, Monero already ranked 10th in terms of trading volume, with its market value beyond 1 billion US dollars, an evidence for its great fame in this field.
By a special method in cryptography, Monero ensures that all transactions remain 100% irrelevant and untraceable. Perhaps after reading this article, you will understand why it is so special and popular in the increasingly transparent and traceable cryptocurrency circle (After all privacy comes first!).
In fact, many large cryptocurrencies in the world are not anonymous. All transactions on Bitcoin and Ethereum are made public and traceable, which means that anyone can eavesdrop on transactions flowing into and out of the wallet. That has given rise to a new type of cryptocurrency called “privacy currency”! These “privacy currencies” hide encrypted transactions by adopting specific types of passwords. One typical example is Monero, one of the largest privacy cryptocurrencies in the world.
Monero was created on April 18, 2014 under the name BitMonero, literally the combination of Bit (Bitcoin) and Monero (the “coin” in Esperanto). In five days, the community decided to change its name to Monero.
Interestingly, Monero’s creators valued personal privacy and tried to behave in a low-key manner with pseudonyms instead of the real names. It is said that the Monero major contributor’s nickname is “thankful for today”, yet this guy has gradually disappeared from public view as Monero developed day by day.
Unlike many cryptocurrencies derived from BTC, Monero is based on the CryptoNote protocol. It is also the first branch based on the Bytecoin of CryptoNote currency. Here is some information about Bytecoin: BCN, for short, is a decentralized cryptocurrency with a high degree of privacy; it has open-source codes that allow everyone to contribute to the development of the Bytecoin network; and the Bytecoin network provides global users with instant private transactions that are not traceable and at no additional cost.
Yet, as a branch of BCN, Monero outshines its parent in reputation by being different in two ways. First, Monero’s target block time was reduced from 120 seconds to 60 seconds; second, the issuance speed was cut by 50% (which reverted to 120-second residence later, with the issuance time maintained and the reward for each new block doubled). By the way, during the fork, the Monero developers also found a lot of low-quality codes and then refactored them. (That is exactly what geeks will do)
Monero’s modular code structure was also highly appreciated by Wladimir J. van der Laan, one of the core maintainers of Bitcoin.
Monero values privacy, decentralization and scalability, and there are significant algorithm differences in blockchain fuzzification, which sets it apart from its peers. How private is it? Here are more details.
1. Safe and reliable
For a decentralized cryptocurrency, decentralization means that its network is operated by users; transactions are confirmed by decentralized consensus and then recorded on the blockchain irrevocably. Monero needs no third party to guarantee the safety of funds;
2. Privacy protection
Monero confuses all transaction sources, amounts, and recipients through ring signatures, ring confidential transactions, and invisible addresses. Apart from all the advantages of a decentralized cryptocurrency, it is by no means inferior in safeguarding privacy;
3. Unable to track
The sender, the receiver and the transaction amount of all Monero transactions must be anonymous by default. The information on the Monero Blockchain cannot be matched with physical individuals or specific users, so there is no trace to track;
4. Scalable
Everyone knows that Bitcoin’sability to process transactions has always been limited by the scalability issue; as we have mentioned before in the introduction of Bitcoin, the block size of 1MB makes things difficult. But Monero’s developers have created a system that allows the network to process more transactions when needed; what’s more, Monero does not have any “pre-set” restrictions on block size.
Of course, this also means that some malicious miners may block the system with large blocks. To prevent this from happening, Monero has worked out countermeasures: the block reward penalty of the system.
On October 18, 2018, Monero’s latest hard fork changed the consensus mechanism algorithm to CrypotoNight V8. In this hard fork, it introduced the BulletProff bulletproof protocol, which can also effectively reduce the transaction fee of miners without disclosing transactions
It is said that Monero will issue about 18.4 million XMR in around 8 years. Moreover, it eclipses its counterparts in distribution — with no pre-mining or pre-sale, all block rewards will be left to miners by means of the POW mechanism.
Here is the reward scheme of Monero in two stages:
  1. Acceleration: mine 18132000 XMR before May 2022;
  2. Deceleration: Deceleration starts right after 18132000 XMR are mined, and there will be a reward of 0.6XMR for each block mined afterwards. In this way, the overall supply will be kept on a small scale and decelerated.
Monero is also excellent in its development concept that is designed to be anti-ASIC from the very beginning. Here is a brief introduction to ASIC (Special Application Integrated Circuit).
Due to the specificity of ASICs, specially designed ASICs can usually have much higher hashrate than general CPUs, GPUs, and even FPGAs — that makes hashrate excessively centralized and makes it vulnerable to the monopoly of single centralized institutions. Yet the cryptonight algorithm used by Monero allows most CPUs and even FPGAs to get involved and get mining rewards, instead of making GPU the only one that can efficiently mine.
In other words, Monero’s core development team will modify the consensus mechanism algorithm and have a hard fork after some time to ensure its strength against ASIC and the monopoly of hashrate.
However, although Monero has been designed against ASICs to avoid centralization, nearly 43% of its hashrate is still owned by 3 mining pools; in addition, it is not a BTC-based currency, making it even harder to introduce some elements. Of course, Monero is not that newbie-friendly, and thus has not been widely accepted.
Yet each cryptocurrency has its own features. As long as Monero keeps improving its privacy, it will definitely attract increasing followers. If you are interested in Monero, welcome to CoinEx for exchange or trade.

THE END OF ALL ASIC MINERS? - Monero's New Superweapon: "Time Locked Proof of Non-ASIC work challenge reward" algorithms.

I propose the following algorithm to end this War of attrition with ASIC / FPGA manufacturers , hopefully once and for all and save us Precious PoW Tweaks during the upcoming forks.
"A time-locked, Proof of 'Non-ASIC work' Challenge reward algorithm"
Here's an image to help you visualise how the algorithm works (details below):
https://imgur.com/a/9S8dA
Here's why we need it:
ASIC manufacturers mine in Secret to attack our decentralized network. They'll win the war since they'll 'get their investment back' before we brick their ASICs, allowing them to launch never-ending attacks against our decentralization, for eternity.
Quick Overview
This algorithm uses the concept of "time-locked reward challenges".
The algorithm ‘time-locks’ the reward, then issues a ‘non-ASIC’ work challenge during each regular PoW Fork, which distributes mined rewards only to CPU and GPU miners who can pass the challenge and prove they are not ASICS, by maintaining their hashrate during the ASIC downtime.
These Hash-rate challenges after PoW Forks successfully ‘detect’, and ‘Severely Penalize’ anyone Mining with an ASIC/FPGA, even those in Secret.
Proof of Concept: An Actual Demonstration
I'll demonstrate this algorithm in action:
Please see this image to help you Visualise how the algorithm works:
https://imgur.com/a/9S8dA
There is a critical flaw and uniquely identifying feature that exists in absolutely 'ALL ASIC and FPGA miners', even those mining in Secret.
As most of you may know, with the upcoming V7 PoW hardfork,
Instead of just destroying an ASIC with a fork, we can further exploit this to attack the ASIC Manufacturer or Miner by taking back all their mined rewards and giving them to the community
The Special timeframe is PoW Fork + 'N' Days. ('N' being however many days remaining where it would be "impossible" to build and startup a new ASIC/FPGA after the fork.)
To exploit this, the algorithm introduces a period of time called the "Mining Rewards Collection Timeframe" (MRCT), the time period in between regular PoW Hardforks. the grey shaded area in this image
This "Mining Rewards Collection Timeframe" is a time whereby all mining profit rewards are 'time-locked' or held hostage in escrow, on either the mining pool, or on the Actual Blockchain code itself, or Both, depending on where this algorithm is eventually deployed.
The algorithm stores the wallet address a mining reward belongs to, and the maximum hash rate (or maximum value adjusted share rate per day) observed during the "Mining rewards collection timeframe" for that particular wallet address.
This "Mining Rewards Collection Timeframe" can be of any duration as required by the developers; 1,2,3,4,5,6 Months or longer . The longer This Timeframe, the more dangerous it is to ASIC miners. Meaning we don't have to rush with forks.
Since it's time-locked, mined coins/rewards cannot be cashed out until the coming challenge; However, mining pools can still choose to payout smaller miners before that time if they have a 'good stable Non-Asic Hash challenge passing history', or a deposit on file, or at their own risk, so most good miners don't have to wait to cashout rewards!. Big miners on the other hand, won't care! Why? Because the delay doesn't cost them anything. (it's a TINY TINY inconvenience compared to the damage ASICs would do to GPU mining profits. I hope this makes sense)
Now for the Critical ANTI-ASIC Work Challenge.
Time passes and the mining rewards collection timeframe ends with a Hardfork that changes the PoW algorithm slightly,
All ASICS and FPGAs are INSTANTLY destroyed.
At the same time, the mining rewards from that collection timeframe are now ready to be paid out.
Since only the CPU / GPU miners are able to hash normally,
The Algorithm now issues a Hash Rate challenge to determine how much of the coins mined were actually mined by ASIC or FPGA miners.
The challenge is nothing special. Miners just have to leave their miners running normally at maximum speed for the period of the challenge, same as they do everyday!
During this challenge, their "Average Maximum Hash rate during the challenge" is compared to the "Maximum Hash Rate speed" recorded on the blockchain during the Mining Rewards Collection Timeframe.
See the green dotted line in the image
Thus at this point, since ASICs are DEAD, they cannot Hash at the same rate during this challenge period, so any significant difference in hashrate would thus clearly indicate the use of an ASIC or FPGA miner.
Now, we have all the information we need to STRIP ASIC Miners of ALL their gains, and Reward GPU miners instead.
As shown in the earlier image
What if a 1 GPU breaks in a 12 GPU mining farm during the challenge? (Very rare) or for some reason, you can't mine during that period? then the miner can simply rent the GPUs from nicehash for the Challenge. An ASIC miner however, cannot use this strategy (because ASICS are not GPUs, explained further below). Also we can implement a 2nd chance option; the confiscated reward may be frozen for the next Cycle; and the miner may get a 2nd chance to prove the hashrate again, with a % reward penalty.
The Beautiful thing is that If ASIC miners fail the challenge, Everyone gets a Bonus share of the Reward Forefitted by the ASIC miners, So Everyone wants the ASIC miners to fail so they get Free extra money. and thus have a financial reason to support this algorithm.
*There is no escaping it... or is there?
Is it ASIC PROOF? Can you Cheat this algorithm?
I've also tried to see if you can work around this algorithm:
  • Example 1: What if they switched in GPUS to mine for an ASIC during the challenge? Well, that wouldn't work. When the challenge comes, they can either save the rewards mined by the GPUs, or save the rewards mined by the ASICs, One will always be lost and result is the same anyway because you'd only get paid for the Hash rate of the GPU. The ASIC portion of the hash rate will ALWAYS be lost.
  • Example 2: What if they use the GPUs to mine a different coin and have them only hash for the ASIC during the challenge period?
  • Consider the Antminer X3. at 200KH/s, to support just "ONE ASIC", they would need over 200 RX 580 Cards or 100 VEGA cards to pass the challenge... costing well over $60,000 (SIXTY THOUSAND DOLLARS) and if they depreciate at ~ 10~15% a year, they'd lose $6000~$9000 a year. it's not enough to cover your losses,
  • Also, What other coin could you mine? If ASICS are so powerful, there won't be another coin except those running this algorithm. Then, the dev can choose to issue the challenge at the same point as the other coin using the same algorithm, so they lose all rewards from one coin as 1 rig cannot sustain two challenge algorithms at the same time.
  • Example 3: What if they just leave some GPUS on standby to avoid the power costs? Then ASIC's would still be unable to be mass produced anyway. Because for every ASIC Mass produced, you'd need to Mass Produce 200 times the GPUS to support them in their place, and own of all them. practically impossible.
  • Example 4: What if they rented hashing power from Nicehash to fill in during the Challenge period?
  • Yes, but so can we! The beautiful thing about this algorithm, is if we rent the limited hashing power on Nicehash first before them at break even or loss, it doesn't matter, Because, the ASIC miner cannot rent and hash rate and will fail the challenge, and Forefit the ENORMOUS amount of Rewards to the community. Imagine, Mining at such a high rate for months on end , the rewards confiscated and paid to GPU miners will easily offset any of the tiny losses renting hashrate from Nicehash, so ultimately, The ASIC miners lose Everything, and the community (you and me) gets all their money.
  • Also if ASICs Dominate the crypto market, there won't be any GPU to rent, all remaining coins would be mining this algorithm, meaning they would have to save their own hashrate for themselves, not rent it to ASIC miners. otherwise they lose their reward. Brand new users may rent their GPU's but its no where near enough to cover the ASIC hash shortfall in the challenge.
  • Example 5: What if they waited till we exhausted our supply of PoW fork tweaks? That's the beauty of this algorithm!. We don't actually have to tweak the PoW algorithm on a constant basis! We can intentionally leave it the same. So Everyone passes the Challenge, Then when we do detect an asic "trying to Mine their Money Back in secret (as they do now)", We tweak the PoW at the Next Hardfork. Destroying and bankrupting their very first attempt, and we get all their money and rewards, So there's no need to waste a PoW tweak in a pre-emptive strike, because the rewards are Time-Locked to the future. We can lie in wait with a single PoW like a Trap, and eat them alive (literally we get all their rewards after the challenge!). We can maintain this lethal threat to ASIC manufacturers without having to change the PoW at all!
And remember, all this effort is just for ONLY, ONE ASIC. meaning you Can't mass produce it.
So ultimately it wouldn't even make sense to even develop an ASIC, as you'd be far more profitable just mining only with the 200+ GPU's required to cheat the algorithm.
*So in summary, *
  • No ASIC/FPGA miner can escape the challenge. Not even those running in secret.
  • All ASIC miners are guaranteed to suffer a huge (possibly fatal) financial loss, with no prospect of any return on investment. Time locked rewards ensure No secret pre-mining with ASICs is possible. ASICs are destroyed with each challenge, all R&D and manufacturing costs and the electricity bill used to power them is wasted for basically "ZERO returns",
  • …..and lets not forget that all their rewards gets given away to other honest miners like you and Me!. ( LOL!) or potentially the developers of the fork :)
  • As long as the algorithm is active and used by multiple coins, no ASICs will ever exist to mine in secret,
  • We save precious PoW tweak changes, since there's no need for a pre-emptive PoW strike to prevent 'ASIC hit and run' pre-mine scenarios.
  • ASIC manufacturers see that the war is un-winnable and go invest in other things,
So, in theory, The War Ends. (at least for a very good part of the future)
As they say: " Don't build a wall and hide in fear.... Build a wall and launch missiles from behind it against the enemy so they will never dare attack us again."
I would like to point out that time locked reward challenges are already in use by the Olympic games to Strip drug cheats in the past by storing samples and testing them in the future, and it's also in the PPLNS minig pool algorithms to deter pool hopping cheats, and also in the Bitcoin's Lightning network in the form of decrementing time-locks" that 'enforce the transfer of funds' under certain conditions.
Is it beautiful? Will it work? Can it be done? Let's discuss this

ASIC Resistance Timeline

Today, in about 30 minutes or less from now, RandomX will be activated on Monero as part of its network protocol upgrade, so this seems like a good moment to share this timeline. It’s like the raw material for writing the history of ASIC resistant proof-of-work algorithms. If you think it’s incomplete, let me know what you’d like to add. I didn’t include Monero ASICs or FPGAs that weren’t publicly released, since it would be difficult to pin down a date.

TLDW; Craig Wright and company have a plan to take over the crypto currency world by dominating hash power to destroy all the competition while changing the rules of the surviving chain (theirs) to fund the next battle.

This plan of attack will be much, much more difficult to execute against an ASIC resistant crypto currency, also against a crypto currency which regularly adapts and forks.

While they flood this sub with their shilling and tipbot, the Monero community ROUTINELY LIES about Bitcoin Cash to newbies!

It's a dead fork of Bitcoin, result of community unhappiness with where Bitcoin was going.
Either way, it's "maintained" by Bitmain (from their wallet at least) which is a non-alternative.
If you want electronic, peer to peer, private cash, Monero is the way to go.
There are at least three big lies in this post if we skip the bitmain statement:
  1. That Bitcoin Cash is a "dead fork" of Bitcion.
  2. That Bitcoin Cash is not usable as p2p, private (CashShuffle) digitial Cash.
  3. That Monero somehow is.
Monero of course is completely unusable in comparison to Bitcoin Cash. You have to wait at the very least 20 minutes after spending your funds before you're able to spend them again. I.e. if you send a submaximal amount of monero, you can't use the rest of your funds for twenty minutes!
Monero is also not any faster transactionally than BCH. Having a faster block time doesn't mean you're faster, it just means you're accepting less security per confirmation.
Not to mention that the Monero core wallet is nearly impossible to sync. Often you are told to use a "remote node", but this dramatically weakens your privacy. More so than the default weakness that comes with Monero's really small anon set, and the tracing attacks linked below.
  1. How buying pot with Monero will get you busted — Knacc attack on Cryptonote coins
  2. Exchange Denial of Service in Monero
  3. Fake deposit amount exchange vulnerability in Monero
  4. Hiding your IP while using Ryo or other Cryptonotes + IP reveal exploit in Monero/OpenAlias
  5. Cryptonight-GPU — FPGA-proof PoW algorithm based on floating point instructions
  6. Tracing Cryptonote ring signatures using external metadata
  7. Newly added - FloodXMR: Low-cost transaction flooding attack with Monero’s bulletproof protocol*
We show how an attacker can take advantage of Monero’s Bulletproof protocol, which reduces transaction fees, to flood the network with his own transactions and, consequently, remove mixins from transaction inputs.
Assuming an attack timeframe of 12 months, our findings show that an attacker can trace up to 47.63% of the transaction inputs at a cost of just 1,746.53 USD.1 Moreover, we show also that more than 90% of the inputs are affected by our tracing algorithm.
  1. That cost was based on transactions with 100 outputs, while the monero protocol limits this number to 16, which increases the cost of the attack to roughly $10,000 USD
A former developer for Monero stated that Monero's privacy doesn't work.
https://www.reddit.com/dashpay/comments/bindps/when_the_fud_finally_fails_and_the_ugly_hot_girl/em92sbz/
fireice_uk stated in his article, there's really no way to fix it.
I didn't say that. I think it can be fixed, however as is, Monero's (and all other cryptonotes') privacy is not fit for purpose.
So why are the Monero members lying about their utility w.r.t. to BCH as digital, private Cash? I think this would be a great discussion to have!

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

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

GPU Mining Crash Course - START HERE!

Welcome All to the GPUMining Crash Course!
With the increase in prices in cryptocurrency, a lot of people are getting back into mining and a lot of people are brand new to the concept overall. So, I quickly wrote this crash course to help you understand what to expect and how to successfully mine your first cryptocurrency. This crash course isn't gonna have all of the fluff you'd see in a normal publication. This is just everything you need to know to get up and running on your first cryptocurrency mining rig.

What is cryptocurrency mining?

One of the main things about cryptocurrencies is that they are "decentralized". Sounds great, but WTF does that even mean? Well, the easiest way to explain it is...
You know how if you want to send your friend/family money digitally, you can do so through your bank. Your bank likely takes a transaction fee and in a few days they will transfer the money. Since cryptocurrencies are decentralized, they don't have a bank or organization to fulfill the transfer of money. Instead, they outsource the computing power of their cryptocurrency network to miners (soon to be you). These miners are verifying transactions, securing the blockchain, and powering the cryptocurrency's specific network among other things. As an incentive, the miners collect transaction fees on the transactions that they verify and collect block rewards while new currency is still being introduced into the ecosystem.

What kind of rig should I build?

You can mine cryptocurrencies using your CPU, GPU, FPGA, or ASIC, but this is a GPU Mining subreddit, so I will cater this to GPUs.
For building a great all-around GPU rig, there are two models of GPUs that I'd recommend:
Both of these GPUs have solid hashrates across most mining algorithms and for a decent price! You should be able to find both of these kinds of GPUs used for around $200-$250 each, which is a great price if you know what happened during the last mining craze! ($200 GPUs were out of stock everywhere and people were reselling them for $600+ each)
There are also plenty of great AMD GPUs for mining, but I've worked mostly with Nvidia so that's why both of my recommendations are Nvidia and not AMD.
Other parts to your rig that you'll need are listed below. Most of these can be pieces of crap and are just needed to make the rig actually run, but the one spot you DON'T want to cheap out on is the power supply unit. A decent power supply unit will keep your home from burning down while also keeping your rigs up and running smoothly. Here are my recommendations:

She's built, now what?

Now you need to do a few things. I am a Windows miner, so I will be speaking to Windows here:
  1. Update Windows - Do all of the updates. Just do it.
  2. Update Drivers - Go to the EVGA website and download GeForce experience. It will keep your GPU drivers up to date.
  3. Go to Windows Device Manager and make sure all of your GPUs show up under "Display Adapters". If it is there, but it isn't showing the Name/Model of the GPU as the name, right click it and select "Update Driver". This should fix it.
Assuming you've done all of this, you're ready to download a mining application.

Mining Software

There are tons to choose from! Claymore, Phoenix, EWBF, LolMiner, etc... It can be overwhelming pretty quickly since they all have different algorithm support, speeds, efficiencies, and a whole lot more. On top of that, in order to get them running you need to set up batch files to call the proper exe, point you to the correct pool, and a whole bunch of other stuff that can be confusing to a new user. Not to mention, you will probably need a separate miner, config file, batch file, etc. for each different algorithm that you're interested in mining on.
Instead, I recommend that you download a miner management software that will take care of most of this tedious work for you. There are a few in the sidebar, but the /GPUMining favorite is AIOMiner. It was developed by our very own community member, xixspiderxix with the intention of making mining as easy as possible to do and without any fees. It supports over 100 different algorithms, so you'll be able to mine nearly ANY cryptocurrency you'd like. Just download it from their website and it will take you through a quick tutorial to help you get set up! You can also connect your rig to their website for remote monitoring and control. You've probably seen a few of their posts around this subreddit.
Other Windows mining softwares include:
Note: Many mining softwares have fees built into them. Most are around 1%, but can go as high as 5% or greater! You want a mining software with little or no fees at all so that you get to keep as much cryptocurrency as possible. These fees aren't something you actively pay, the software will automatically take it by mining on the developers behalf for a given amount of time and then switching back to mining on your own behalf. So, please be diligent in the software that you evaluate and make sure it is reputable.

I keep hearing about NiceHash. What is that?

The asshole of the mining industry. Jk, but not really.
NiceHash is a software program that allows you to sell your rig's hashing power to someone on their marketplace. They market themselves as profitable mining, but you're not really mining. You're selling your power in exchange for Bitcoin.
They did a great job telling people that with them, you're always mining the most profitable coin, but that's just not true. Since it is a mining marketplace, they make you mine whatever their most expensive contract is. If their contracts are below market prices, then you're not operating as efficiently and profitably as you could be.
NiceHash also has a sketchy history, which continues to this day. In 2017, they were hacked and lost $65M worth of Bitcoin. No one got paid out for MONTHS and many of their executives conveniently resigned. Their platform is also used to destroy cryptocurrencies. Since people are able to purchase mining power on their platform, people have used their platform to purchase enough mining power to control individual cryptocurrencies and duplicate coins, which increased the malicious user's wealth while completely destroying the integrity of the coin's blockchain. HoriZEN (formerly ZenCash), Ethereum Classic, and many other great cryptocurrencies have been the victim of NiceHash's platform.
For this and many other reasons, we highly recommend that you stay AWAY from Nicehash. We understand that it is extremely easy to use and you get paid in bitcoin, but they are destroying the industry with their greed and lack of motivation to change their platform for the protection of cryptocurrencies.

Concluding Thoughts

This is pretty much everything you need to know to get started. We covered the hardware, setting up the software, which software to use, and AIOMiner's tutorial will get you up to speed on how to actually mine the cryptocurrency that you want better than I can explain it, so I'll leave that part to them.
If you have any questions on this crash course, please leave a comment below where myself and other community members will be able to help you out.

Which is the most important hardware to mine cryptocurrency?

Crypto mining equipment is specifically designed to solve blockchain hash functions at a faster rate than other hardware solutions. Traditional computers are built with a processor known as a Central Processing Unit (CPU), which is designed to compute the functions needed for a standard computer.
Alternatively, mining hardware is built with different, more advance processors. Yet, these aren’t just high-powered computers. Crypto mining equipment is more efficient than typical hardware at solving computational hashes required to successfully mine blockchains.
MINING HARDWARE DETAILS
There are several things to look out for when it comes to purchasing cryptocurrency mining hardware and equipment.[1]
First, these machines must not just be powerful, but energy efficient as well. Since the number one cost in crypto mining is electricity, a good piece of mining equipment must consume less power while still maintaining its high-powered usage. This makes a key factor in crypto mining hardware hashes per second per watt of power, which determines how much power is consumed for a given amount of hash power.
Second, because cryptocurrency mining is done 24/7/365, the equipment used to mine must be able to operate on a continuous basis. This means, equipment is designed for optimal cooling so as to not overheat from continuous use, as well as setting up equipment in a way which will allow for the most optimal cooling. If you are unsure how this can be done it may be best to outsource the installation and hosting of your mining hardware to a third-party provider with the proper tools and resources to service mining equipment.
TYPES OF MINING HARDWARE
There are three types of mining hardware: GPU, FPGA, and ASIC. The type of hardware used is dependent on the blockchain being mined. While ASIC-based hardware may be the most powerful for some blockchains (such as Bitcoin), they are rendered almost useless in other blockchains (such as ZCash) whose hashing algorithm is designed to be resistant to ASIC hardware.
Choosing the correct piece of mining hardware is one of the most important parts of cryptocurrency mining, as the wrong choice could result in a significant loss of potential profits and time.
All in all, it has become clear over the past several years that cryptocurrency mining hardware is necessary for anyone looking to make a profit in mining. Determining which piece of mining equipment is most suitable for your needs is dependent on many factors such as your budget and the blockchain being mined.

AMA with Sinovate, a new GPU friendly coin with new innovations to the space

SINOVATE
What SINOVATE is aiming on Cryptocurrency Market?
SINOVATE is created for Innovation and it aims to keep bringing never before seen Innovations in the crypto market.
What is Infinity Nodes, why different from Classical Masternode System? Infinity Nodes are groundbreaking evolved masternodes that solves the inflation problem. Traditional masternodes start with high ROI but with very large inflation and that inflation is what inevitably makes them fail.
What is IDS, why is it better than cloud storage? And size providers how to get/ earn SIN?
IDS = Incorruptible Data Storage.
IDS is a peer-to-peer private networking system, which will permit transactions and storage between miners and Infinity Node owners. Competitors including Sia, Storj, BitTorrent and even IPFS solutions reward individuals for serving and hosting content on their hard drive space, which requires a 24/7 uptime for computers. User hard drives must remain open and the rewards received must justify the costs incurred for leaving computer online.
In IDS, the private networking of decentralized storage relies solely on the SINOVATE Blockchain, with only node owners receiving rewards as compensation for utilising their hard drive resources to run an Infinity Node. Node owners will get rewards both from the Infinity Nodes and from storing confidential data.
IDS will have 5 steps of evolution.
SINOVATE has 533 tp/s. How are you planning to use this as a use case?
Scalability is one of the biggest problems in cryptocurrencies. POS only or centralized cryptocurrencies have higher scalability but are not suitable for the original Satoshi plan. Satoshi Nakamoto’s dream was everybody to mine their own coins without being centralized so SINOVATE blockchain not only is the most scalable POW cryptocurrency but will also have much more increased scalability in the future. Mass adoption requires high scalability especially when it will be used in real life as a payment means. Are we going to see SINOVATE Payment System in the future?
SINOVATE payment gateway will be released this year with high scalability and less than 3 seconds transaction times with the help of FlashSend.
What is SINOVATE aiming with X25X Algorithm?
SINOVATE formerly SUQA always aimed at the ordinary user starting with the X22i custom algorithm and upgraded to X25X to fight the big hardware companies so everyone can mine their own coin without letting ASIC,FPGA companies dominate the network.
Algo Comparison Chart
We are committed to remaining ASIC / FPGA resistant and such use an ever evolving algorithm, the latest variation named X25X launched with the last update. It is protected from difficulty attacks using Dark Gravity Wave v3 and raises the memory requirements compared to X22i bt a factor of five making it harder for ASIC / FPGA to implement.
What is Komodo dPOW , and when is the plan implementation on SINOVATE?
dPoW diagram
KOMODO DPoW is a working and trusted 51 % Attack protection technology to prevent any kind of malicious attacks by the help of notarized data of Bitcoin, KOMODO and SINOVATE chain.
What is the current status on mobile wallets? We saw a mobile wallet trailer.
Mobile wallets will be released in July 2019 as a custom good looking wallet tailored to the specific needs of SIN Blockchain
What is the plan for adoption in real life SINOVATE?
Our team draws from a large diversity of skills from many areas of business and across many different industries. This allows us to design and hone the experience of interacting with the SINOVATE Blockchain at many levels, from developers, business leaders and operational levels, down to the end-user experience.
This allows us to develop software and user experiences from the perspective of all involved, ensuring that the end user is the primary focus.
What is the current financial status on SINOVATE?
SINOVATE are transparent about the financial status of the foundation and the activity taken with funds. We regularly publish updates and the latest one for June is here.
What partnerships will there be in the future?
Besides the Masternodes related partnerships, SINOVATE partnered with KOMODO for the integration of dPoW 51% attack protection, which will be active at the end of July or early August 2019.
As the foundation’s mission is to grow the space for all. We are happy to work with all projects and businesses both by learning from the great work others have undertaken and offering something back to other projects with our open source code.
With Governance what can it do for the community?
Decentralized governance is the future of any successful blockchain project, SINOVATE believes that blockchain will be ubiquitous in the underlying infrastructure and services in the future of everyday life. Having fair voting for developments, marketing and innovations of the SINOVATE chain will be very important for everyone.
Hopefully that covers as an introduction, please fire away below with any questions you might have for us and feel free to join sinovate for the latest news!
Edit - Thanks for the great questions and discussion. First round answered by our CEO u/cryplander, feel free to shoot more :)

Proposal to switch to SHA-3 proof of work

https://github.com/aeonix/aeon/issues/103

I believe now is the right time for Aeon to become ASIC friendly by switching to SHA-3 PoW (the most recent Secure Hashing Algorithm standardized by NIST). Below I'll try to explain why:

There is no such thing as ASIC resistant PoW.

Whether someone creates an ASIC or not is not determined by how technologically difficult it is to do so, but how economically sensible it is to do so; i.e., when a coin gets more adopted and the price rises, ASICs will appear no matter what.
Below is a quote from Bitcoin StackExchange which makes a good point:
It's not really "someone figured out" how to mine on FPGAs or ASICs: an intelligent first year undergraduate could port SHA256 from C to Verilog. It's more that it began to make economic sense. ASICs in particular require a big enough up-front investment that you need economies of scale. – Peter Taylor Nov 9 '17 at 23:27
https://bitcoin.stackexchange.com/questions/62336/why-did-satoshi-design-bitcoin-to-be-mineable-only-on-specialized-hardware-if-t#comment71658_62339
For every supposedly ASIC resistant PoW (scrypt, CryptoNight etc), ASICs have been created at some point when the coin became sufficiently large. An often seen argument is "CryptoNight was good at resisting ASICs because it survived the first 3 years without ASICs being developed", which I disagree. CryptoNight ASICs weren't created for the first 3 years simply because the market was too small; it wasn't worthwhile to develop CryptoNight ASICs.
Currently RandomX is receiving a lot of attention as being (almost) truly ASIC resistant by making PoW even more complex, but from the past experience and from logical reasoning, I have no reason to believe so.

Importance of protocol stability:

As a coin gets more widely adopted (and the price goes up), there will be more participants in the network (users, exchanges, merchants, pools, etc), which makes it more difficult to do hard forks (i.e. to force everyone to upgrade their software). Monero's 6 month fork schedule is already becoming almost unworkable due to the sheer network size, and I think they'll be forced to change this policy rather soon.
Imagine a hypothetical future where one particular crypto coin becomes a globally adopted world currency. That coin cannot do hard forks every so often; maybe once every two years is already too much. Ideally, at some point, the protocol should become absolutely stable and require no more hard forks at all.
With this in mind, I immediately see ASIC resistance being incompatible with this future, because hard forks (PoW changes) are rather frequently needed due to ASICs getting created faster and faster as the coin grows. ASIC resistance cannot be a sane strategy for a winning cryptocurrency.

Importance of switching now:

Going from ASIC resistant to ASIC friendly is such a radical change, and a strong opposition is naturally expected from many of the community members who have been supporting ASIC resistance. A compromise solution suggested by u/smooth_xmr is to adopt CryptonightR which Monero will switch to in the next upcoming hard fork. I think the reasoning is that CN-R is expected to be somewhat better at resisting ASICs and not much more computationally expensive than the previous CN variants (unlike RandomX), so we can wait and see how successful this will be before going full ASIC friendly.
Initially I felt OK with it, but I became unsatisfied after a while of thinking for these reasons:

Arguments for ASIC resistance and their counterarguments:

SHA-3 is the perfect way for Aeon to differentiate itself from Monero.

This change is radical but not stupid. Many people in the Monero community would be curious how things will play out for SHA-3 Aeon. This will surely also attract a lot of attention from the wider crypto community because Aeon will be the first CryptoNote coin that deployed SHA-3. I believe this is a very good opportunity for marketing as well.

Please discuss.

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

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

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

Author: Rolf Versluis - co-founder of Horizen

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

Technology Progression

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

Cryptocurrency Price Cycle

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

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

Managing Cash for Miners

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

Actions to Take During the Cycle

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

An Update on Horizen - formerly ZenCash

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

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

Für Bitcoin allerdings existieren bereits ASICs, was bedeutet, dass es keinen Sinn macht mit einem FPGA Bitcoin zu minen, denn ASICs sind um einiges effektiver. Auch Ethereum ist nicht eine der Stärken der FPGAs, denn ETH's PoW-Algoritmus (Ethash) ist speicher-intensiv. Die Stärke der FPGAs liegt allerdings im Kern und somit wäre die Hashrate von FPGAs und GPUs ungefähr gleichauf. FPGAs ... This algorithm was originally implemented in the CryptoNote protocol and it was basically designed to be inefficiently computable on FPGA / ASIC architectures.
