"A few months after the Counterparty developers started using OP_RETURN, bitcoin developers decreased the size of OP_RETURN from 80 bytes to 40 bytes. The sudden decrease in the size of the OP_RETURN function stopped networks launched on top of bitcoin from operating properly."

Some info on how Core/Greg Maxwell ended Counterparty before it could get started.
Several years ago, there was a conflict between Counterparty and bitcoin developers. Counterparty was using Bitcoin’s OP_RETURN function which enabled anyone to store any type of data in transactions. By using OP_RETURN Counterparty was able to operate as the first decentralized digital asset exchange using blockchain technology.
A few months after the Counterparty developers started using OP_RETURN, bitcoin developers decreased the size of OP_RETURN from 80 bytes to 40 bytes. The sudden decrease in the size of the OP_RETURN function stopped networks launched on top of bitcoin from operating properly. As a result, Counterparty had to move away from the OP_RETURN function and other blockchain projects which were initially planned to launch on the Bitcoin protocol.

The very approach of Ethereum towards smart contracts and Solidity’s so-called Turing-completeness to be used by EVMParty have also been subject to criticism from bitcoin maximalists. In particular, Gregory Maxwell of Bitcoin Core said that the platform’s imperfection consists in including unnecessary calculations in the blockchain, which may apply significant load on the network. Eventually, such approach may slow down the blockchain. Finally, calculating on a blockchain is expensive. Maxwell believes that bitcoin developers’ approach towards smart contracts is way more flexible as it records only confirmations of calculations.

Feel free to share if you have anything to add. I always remember Gmaxwell getting triggered everytime Counterparty was brought up. He would seemingly go out of his way to tear it down if a post even resembled reference to it. Sadly I don't have any of these other example on hand.

Bitcoin mining: how is a block header of 80 bytes processed in SHA-256? Isn't it too big?

The whole process of bitcoin mining was making sense to me until a moment of madness an hour ago, if there is 80 bytes of data to be processed in SHA-256, that's 640 bits of data to be processed in SHA-256.
In this 80 bytes we have: 4 bytes (version), previous block hash (32 bytes), merkle root (32 bytes), time (4 bytes), bits (4 bytes), nonce (4 bytes).
I thought SHA-256 accepted 512 bits of data, so that's 64 bytes of data. And on top of that, I need to add the length of the data to be processed in the last 64 bits of this 512 bits input but 64 bytes is well over the limit.
What am I missing here? Can someone help hear it up for me?
Thanks

If you dont know bitcoin has just included an official 80 byte hashing data field in transactions which will hugely expand the bitcoin system far beyond money. Suddenly bitcoin displaces records,registrations, notarys and much more.

We need to start calling it the BitSystem.
It is now far more than money and we need to emphasize this so the monetary regulations dont crush it all. It doesnt drop the money functions of course. Btcoin is now a subset funding function of the whole Bitsystem which will probably continue to expand to include other unanticipatd functions.
For more on the official adoption of the data field read. https://bitcoinfoundation.org/blog/?p=290

Technical: The Path to Taproot Activation

Taproot! Everybody wants to have it, somebody wants to make it, nobody knows how to get it!
(If you are asking why everybody wants it, see: Technical: Taproot: Why Activate?)
(Pedants: I mostly elide over lockin times)
Briefly, Taproot is that neat new thing that gets us:
So yes, let's activate taproot!

The SegWit Wars

The biggest problem with activating Taproot is PTSD from the previous softfork, SegWit. Pieter Wuille, one of the authors of the current Taproot proposal, has consistently held the position that he will not discuss activation, and will accept whatever activation process is imposed on Taproot. Other developers have expressed similar opinions.
So what happened with SegWit activation that was so traumatic? SegWit used the BIP9 activation method. Let's dive into BIP9!

BIP9 Miner-Activated Soft Fork

Basically, BIP9 has a bunch of parameters:
Now there are other parameters (name, starttime) but they are not anywhere near as important as the above two.
A number that is not a parameter, is 95%. Basically, activation of a BIP9 softfork is considered as actually succeeding if at least 95% of blocks in the last 2 weeks had the specified bit in the nVersion set. If less than 95% had this bit set before the timeout, then the upgrade fails and never goes into the network. This is not a parameter: it is a constant defined by BIP9, and developers using BIP9 activation cannot change this.
So, first some simple questions and their answers:

The Great Battles of the SegWit Wars

SegWit not only fixed transaction malleability, it also created a practical softforkable blocksize increase that also rebalanced weights so that the cost of spending a UTXO is about the same as the cost of creating UTXOs (and spending UTXOs is "better" since it limits the size of the UTXO set that every fullnode has to maintain).
So SegWit was written, the activation was decided to be BIP9, and then.... miner signalling stalled at below 75%.
Thus were the Great SegWit Wars started.

BIP9 Feature Hostage

If you are a miner with at least 5% global hashpower, you can hold a BIP9-activated softfork hostage.
You might even secretly want the softfork to actually push through. But you might want to extract concession from the users and the developers. Like removing the halvening. Or raising or even removing the block size caps (which helps larger miners more than smaller miners, making it easier to become a bigger fish that eats all the smaller fishes). Or whatever.
With BIP9, you can hold the softfork hostage. You just hold out and refuse to signal. You tell everyone you will signal, if and only if certain concessions are given to you.
This ability by miners to hold a feature hostage was enabled because of the miner-exit allowed by the timeout on BIP9. Prior to that, miners were considered little more than expendable security guards, paid for the risk they take to secure the network, but not special in the grand scheme of Bitcoin.

Covert ASICBoost

ASICBoost was a novel way of optimizing SHA256 mining, by taking advantage of the structure of the 80-byte header that is hashed in order to perform proof-of-work. The details of ASICBoost are out-of-scope here but you can read about it elsewhere
Here is a short summary of the two types of ASICBoost, relevant to the activation discussion.
Now, "overt" means "obvious", while "covert" means hidden. Overt ASICBoost is obvious because nVersion bits that are not currently in use for BIP9 activations are usually 0 by default, so setting those bits to 1 makes it obvious that you are doing something weird (namely, Overt ASICBoost). Covert ASICBoost is non-obvious because the order of transactions in a block are up to the miner anyway, so the miner rearranging the transactions in order to get lower power consumption is not going to be detected.
Unfortunately, while Overt ASICBoost was compatible with SegWit, Covert ASICBoost was not. This is because, pre-SegWit, only the block header Merkle tree committed to the transaction ordering. However, with SegWit, another Merkle tree exists, which commits to transaction ordering as well. Covert ASICBoost would require more computation to manipulate two Merkle trees, obviating the power benefits of Covert ASICBoost anyway.
Now, miners want to use ASICBoost (indeed, about 60->70% of current miners probably use the Overt ASICBoost nowadays; if you have a Bitcoin fullnode running you will see the logs with lots of "60 of last 100 blocks had unexpected versions" which is exactly what you would see with the nVersion manipulation that Overt ASICBoost does). But remember: ASICBoost was, at around the time, a novel improvement. Not all miners had ASICBoost hardware. Those who did, did not want it known that they had ASICBoost hardware, and wanted to do Covert ASICBoost!
But Covert ASICBoost is incompatible with SegWit, because SegWit actually has two Merkle trees of transaction data, and Covert ASICBoost works by fudging around with transaction ordering in a block, and recomputing two Merkle Trees is more expensive than recomputing just one (and loses the ASICBoost advantage).
Of course, those miners that wanted Covert ASICBoost did not want to openly admit that they had ASICBoost hardware, they wanted to keep their advantage secret because miners are strongly competitive in a very tight market. And doing ASICBoost Covertly was just the ticket, but they could not work post-SegWit.
Fortunately, due to the BIP9 activation process, they could hold SegWit hostage while covertly taking advantage of Covert ASICBoost!

UASF: BIP148 and BIP8

When the incompatibility between Covert ASICBoost and SegWit was realized, still, activation of SegWit stalled, and miners were still not openly claiming that ASICBoost was related to non-activation of SegWit.
Eventually, a new proposal was created: BIP148. With this rule, 3 months before the end of the SegWit timeout, nodes would reject blocks that did not signal SegWit. Thus, 3 months before SegWit timeout, BIP148 would force activation of SegWit.
This proposal was not accepted by Bitcoin Core, due to the shortening of the timeout (it effectively times out 3 months before the initial SegWit timeout). Instead, a fork of Bitcoin Core was created which added the patch to comply with BIP148. This was claimed as a User Activated Soft Fork, UASF, since users could freely download the alternate fork rather than sticking with the developers of Bitcoin Core.
Now, BIP148 effectively is just a BIP9 activation, except at its (earlier) timeout, the new rules would be activated anyway (instead of the BIP9-mandated behavior that the upgrade is cancelled at the end of the timeout).
BIP148 was actually inspired by the BIP8 proposal (the link here is a historical version; BIP8 has been updated recently, precisely in preparation for Taproot activation). BIP8 is basically BIP9, but at the end of timeout, the softfork is activated anyway rather than cancelled.
This removed the ability of miners to hold the softfork hostage. At best, they can delay the activation, but not stop it entirely by holding out as in BIP9.
Of course, this implies risk that not all miners have upgraded before activation, leading to possible losses for SPV users, as well as again re-pressuring miners to signal activation, possibly without the miners actually upgrading their software to properly impose the new softfork rules.

BIP91, SegWit2X, and The Aftermath

BIP148 inspired countermeasures, possibly from the Covert ASiCBoost miners, possibly from concerned users who wanted to offer concessions to miners. To this day, the common name for BIP148 - UASF - remains an emotionally-charged rallying cry for parts of the Bitcoin community.
One of these was SegWit2X. This was brokered in a deal between some Bitcoin personalities at a conference in New York, and thus part of the so-called "New York Agreement" or NYA, another emotionally-charged acronym.
The text of the NYA was basically:
  1. Set up a new activation threshold at 80% signalled at bit 4 (vs bit 1 for SegWit).
    • When this 80% signalling was reached, miners would require that bit 1 for SegWit be signalled to achive the 95% activation needed for SegWit.
  2. If the bit 4 signalling reached 80%, increase the block weight limit from the SegWit 4000000 to the SegWit2X 8000000, 6 months after bit 1 activation.
The first item above was coded in BIP91.
Unfortunately, if you read the BIP91, independently of NYA, you might come to the conclusion that BIP91 was only about lowering the threshold to 80%. In particular, BIP91 never mentions anything about the second point above, it never mentions that bit 4 80% threshold would also signal for a later hardfork increase in weight limit.
Because of this, even though there are claims that NYA (SegWit2X) reached 80% dominance, a close reading of BIP91 shows that the 80% dominance was only for SegWit activation, without necessarily a later 2x capacity hardfork (SegWit2X).
This ambiguity of bit 4 (NYA says it includes a 2x capacity hardfork, BIP91 says it does not) has continued to be a thorn in blocksize debates later. Economically speaking, Bitcoin futures between SegWit and SegWit2X showed strong economic dominance in favor of SegWit (SegWit2X futures were traded at a fraction in value of SegWit futures: I personally made a tidy but small amount of money betting against SegWit2X in the futures market), so suggesting that NYA achieved 80% dominance even in mining is laughable, but the NYA text that ties bit 4 to SegWit2X still exists.
Historically, BIP91 triggered which caused SegWit to activate before the BIP148 shorter timeout. BIP148 proponents continue to hold this day that it was the BIP148 shorter timeout and no-compromises-activate-on-August-1 that made miners flock to BIP91 as a face-saving tactic that actually removed the second clause of NYA. NYA supporters keep pointing to the bit 4 text in the NYA and the historical activation of BIP91 as a failed promise by Bitcoin developers.

Taproot Activation Proposals

There are two primary proposals I can see for Taproot activation:
  1. BIP8.
  2. Modern Softfork Activation.
We have discussed BIP8: roughly, it has bit and timeout, if 95% of miners signal bit it activates, at the end of timeout it activates. (EDIT: BIP8 has had recent updates: at the end of timeout it can now activate or fail. For the most part, in the below text "BIP8", means BIP8-and-activate-at-timeout, and "BIP9" means BIP8-and-fail-at-timeout)
So let's take a look at Modern Softfork Activation!

Modern Softfork Activation

This is a more complex activation method, composed of BIP9 and BIP8 as supcomponents.
  1. First have a 12-month BIP9 (fail at timeout).
  2. If the above fails to activate, have a 6-month discussion period during which users and developers and miners discuss whether to continue to step 3.
  3. Have a 24-month BIP8 (activate at timeout).
The total above is 42 months, if you are counting: 3.5 years worst-case activation.
The logic here is that if there are no problems, BIP9 will work just fine anyway. And if there are problems, the 6-month period should weed it out. Finally, miners cannot hold the feature hostage since the 24-month BIP8 period will exist anyway.

PSA: Being Resilient to Upgrades

Software is very birttle.
Anyone who has been using software for a long time has experienced something like this:
  1. You hear a new version of your favorite software has a nice new feature.
  2. Excited, you install the new version.
  3. You find that the new version has subtle incompatibilities with your current workflow.
  4. You are sad and downgrade to the older version.
  5. You find out that the new version has changed your files in incompatible ways that the old version cannot work with anymore.
  6. You tearfully reinstall the newer version and figure out how to get your lost productivity now that you have to adapt to a new workflow
If you are a technically-competent user, you might codify your workflow into a bunch of programs. And then you upgrade one of the external pieces of software you are using, and find that it has a subtle incompatibility with your current workflow which is based on a bunch of simple programs you wrote yourself. And if those simple programs are used as the basis of some important production system, you hve just screwed up because you upgraded software on an important production system.
And well, one of the issues with new softfork activation is that if not enough people (users and miners) upgrade to the newest Bitcoin software, the security of the new softfork rules are at risk.
Upgrading software of any kind is always a risk, and the more software you build on top of the software-being-upgraded, the greater you risk your tower of software collapsing while you change its foundations.
So if you have some complex Bitcoin-manipulating system with Bitcoin somewhere at the foundations, consider running two Bitcoin nodes:
  1. One is a "stable-version" Bitcoin node. Once it has synced, set it up to connect=x.x.x.x to the second node below (so that your ISP bandwidth is only spent on the second node). Use this node to run all your software: it's a stable version that you don't change for long periods of time. Enable txiindex, disable pruning, whatever your software needs.
  2. The other is an "always-up-to-date" Bitcoin Node. Keep its stoarge down with pruning (initially sync it off the "stable-version" node). You can't use blocksonly if your "stable-version" node needs to send transactions, but otherwise this "always-up-to-date" Bitcoin node can be kept as a low-resource node, so you can run both nodes in the same machine.
When a new Bitcoin version comes up, you just upgrade the "always-up-to-date" Bitcoin node. This protects you if a future softfork activates, you will only receive valid Bitcoin blocks and transactions. Since this node has nothing running on top of it, it is just a special peer of the "stable-version" node, any software incompatibilities with your system software do not exist.
Your "stable-version" Bitcoin node remains the same version until you are ready to actually upgrade this node and are prepared to rewrite most of the software you have running on top of it due to version compatibility problems.
When upgrading the "always-up-to-date", you can bring it down safely and then start it later. Your "stable-version" wil keep running, disconnected from the network, but otherwise still available for whatever queries. You do need some system to stop the "always-up-to-date" node if for any reason the "stable-version" goes down (otherwisee if the "always-up-to-date" advances its pruning window past what your "stable-version" has, the "stable-version" cannot sync afterwards), but if you are technically competent enough that you need to do this, you are technically competent enough to write such a trivial monitor program (EDIT: gmax notes you can adjust the pruning window by RPC commands to help with this as well).
This recommendation is from gmaxwell on IRC, by the way.

Market News
Stocks rose further with the S&P edging ever closer to all-time highs. Trump signed an executive order banning TikTok from operating in the US if not sold from their Chinese parent company, ByteDance. So far, Microsoft is the most likely candidate to buy the video-sharing app’s US operations, which has 100 million users. This has triggered uncertainty for market-leading tech stocks.
Gold prices once again hit new all time highs this week after breaking the $2,000 per ounce level for the first time ever. Bank of America Securities analysts predict further upside potential given the extensive quantitative easing being implemented across the globe. With the U.S Fed targeting aggressive inflation, this further buoys the price forecasts for the precious metal.
Bitcoin broke through its key resistance a week prior to gold. Since the breakout, it set highs of over $12,000 before selling off and finding support. Ethereum reached and tested the $400 level while Ripple also recorded significant gains. Overall there is significant upward momentum with sentiment strongly in favour of the bulls.
The Invictus Margin Lending (IML) Fund had a record breaking week with daily annualized returns peaking at 32.83%. Annualized returns for the week totaled 19.78% as demand for credit increased in parallel with the upward price momentum of the cryptoasset class.

Network effect doesn't explain Bitcoin dominance : technical arguments for Bitcoin Maximalism

I often saw some Bitcoiners counter the altcoin shillers with the following argument: "Bitcoin is the first so it has the network effect, so your altcoin will always worth less"
This is not totally wrong but I think this argument is bad. Using it implies implicitly that you admit that Bitcoin is technically less capable than altcoins with their higher transaction rate, fast blocks, instant confirmation, without fees and smart contract support....

And this is WRONG ! Bitcoin price is higher, because Bitcoin is already TECHNICALLY BETTER than any other altcoin and not because of network effect. In 2017, Bitcoin dominance was lower, some altcoin reaches almost the same level than Bitcoin. So network effect is not what prevents an altcoin to take the lead but it is the fact that almost all altcoin that pretend to be better than Bitcoin are technically flawed.
Why ? They use bigger blocks, DAGs (Directed Acyclic Graphs, like used in IOTA or Nano) or wtf they created to disturbe you and make you believe they are better than the good old Bitcoin blockchain. But they have at least one of these two weak points: validation time oand bandwidth.

If they use biggefaster blocks, validation time of block is higher and so block propagation is slower. Less nodes can operate as they may not be able to validate blocks fast enough to keep up with the tip of the chain. You end up like Ethereum that has less and less full verification nodes leading to centralization of the network.
If they use DAGs, they achieve consensus through a "proof-of-stake" vote and always at the cost of bandwidth (quadratic cost in number of node, linear in transaction rate). DAGs are often presented as "each node has its own ledger" but the reality is that the only global ledger you should trust is the complete DAG of the ledgers of each node. Only servers with a shitload of download bandwidth can maintain it as debunked here and here. To not look (in fact be) centralized, some DAG altcoins doesn't, opening the door to history rewrite by buying account that owned a big stake before and still use a lot of bandwidth to reach consensus. Bitcoin just add 80 bytes of proof-of-work data on a block of 1-2MB to achieve it and protect from history rewrite, almost zero cost for the network (that's why we pay fees to miners who carry the cost).
You only have those problems when it reaches a critical level of usage and only then we can see how much those limits where ignored. Until now, very few altcoins reached the limit (maybe Ethereum, and IOTA shows us it is centralized already by stopping the network)
Bitcoin has the highest price because Bitcoin is technically the only possible decentralized king (and a centralized cryptocurrency worths nothing). Yes maybe 1MB limit was too conservativ, yes fees are higher, yes 10 minutes is slow. But if everyone wants their coffee payment to be settled onchain, 1MB or 8MB or 32MB each 10 minutes, minutes or secondes will never be enough while it is a big difference for the network health. You only need the blockchain for settlement, for payment you have Lightning Network that can already destroy PayPal's transaction rate.
So next time you feel convinced by an altcoin that pretend to be better than Bitcoin while being decentralized by design, evaluate the requirement to be a fully validating node and what the overhead of bandwidth needed to achieve consensus. The chances are high that they didn't take care of one of these two issues and end up centralized or broken. You don't need the network effect argument.

ProxyGate

ProxyGate
Hello reddit, I was playing games yesterday, when I realised my cpu and memory usage was extremely high. I was looking through task manager, and saw a substantial amount was due PG COMPONENT 32. I did some research and apparently, it ties into something called cloud.exe. Most sites are telling me that its a virus, and I want to remove it. I have attached the folder of said Cloud.exe (part of PROXYGATE), and was about to delete it. However, I am not sure what to do. Alarmingly, malwarebytes reported some sort of bitcoin miner, along with the cloud. Please help me finding a solution and also tell me about a good (and free) AV, I can use to protect myself in the future
Edit: I would like to post an update here. I downloaded MalwareBytes, and tried to delete the files this time. Not only that, it detected 100s of malware, bitcoin miners etc on my system. I removed them all, and my computer has never been faster; my cpu usage, ram have gone down by more that 80%. Thank you guys for the help and advice.

Reality check..

We have just seen the worst market crash since 1987 and a worldwide epidemic has just been declared... And it still only costs you 80 sat/byte ($0.59) to get a Bitcoin transaction confirmed into the next block.
