[uncensored-r/Bitcoin] How would I set a website up to mine BTC when viewers are on?
The following post by Brodoof is being replicated because the post has been silently removed. The original post can be found(in censored form) at this link: np.reddit.com/ Bitcoin/comments/70otyf The original post's content was as follows:
Title. I saw that TPB was doing this and am interested. I know it's done off of CPU so I might want to use an altcoin, and it's slower than normal, but how would I actually do this?
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:
Multisignatures (n-of-n, k-of-n) that are just 1 signature (1-of-1) in length!! (MuSig/Schnorr)
Better privacy!! If all contract participants can agree, just use a multisignature. If there is a dispute, show the contract publicly and have the Bitcoin network resolve it (Taproot/MAST).
Activation lets devs work get back to work on the even newer stuff like!!!
Cross-input signature aggregation!! (transaction with multiple inputs can have a single signature for all inputs) --- needs Schnorr, but some more work needed to ensure that the interactions with SCRIPT are okay.
Block validation - Schnorr signatures for all taproot spends in a block can be validated in a single operation instead of for each transaction!! Speed up validation and maybe we can actually afford to increase block sizes (maybe)!!
SIGHASH_ANYPREVOUT - you know, for Decker-Russell-Osuntokun ("eltoo") magic!!!
OP_CHECKTEMPLATEVERIFY - vaulty vaults without requiring storing signatures, just transaction details!!
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!
bit - A field in the block header, the nVersion, has a number of bits. By setting a particular bit, the miner making the block indicates that it has upgraded its software to support a particular soft fork. The bit parameter for a BIP9 activation is which bit in this nVersion is used to indicate that the miner has upgraded software for a particular soft fork.
timeout - a time limit, expressed as an end date. If this timeout is reached without sufficient number of miners signaling that they upgraded, then the activation fails and Bitcoin Core goes back to the drawing board.
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:
Why not just set a day when everyone starts imposing the new rules of the softfork?
This was done classically (in the days when Satoshi was still among us). But this might argued to put too much power to developers, since there would be no way to reject an upgrade without possible bad consequences. For example, developers might package an upgrade that the users do not want, together with vital security bugfixes. Either you live without vital security bugfixes and hire some other developers to fix it for you (which can be difficult, presumably the best developers are already the ones working on the codebase) or you get the vital security bugfixes and implicitly support the upgrade you might not want.
Sure, you could fork the code yourself (the ultimate threat in the FOSS world) and hire another set of developers who aren't assholes to do the dreary maintenance work of fixing security bugs, but Bitcoin needs strong bug-for-bug compatibility so everyone should really congregate around a single codebase.
Basically: even the devs do not want this power, because they fear being coerced into putting "upgrades" that are detrimental to users. Satoshi got a pass because nobody knew who he was and how to coerce him.
Suppose the threshold were lower, like 51%. If so, after activation, somebody can disrupt the Bitcoin network by creating a transaction that is valid under the pre-softfork rules, but are invalid under the post-softfork rules. Upgraded nodes would reject it, but 49% of miners would accept it and include it in a block (which makes the block invalid) And then the same 49% would accept the invalid block and build on top of that, possibly creating a short chain of doomed invalid blocks that confirm an invalid spend. This can confuse SPV wallets, who might see multiple confirmations of a transaction and accept the funds, but later find that in fact it is invalid under the now-activated softfork rules.
Thus, a very high threshold was imposed. 95% is considered safe. 50% is definitely not safe. Due to variance in the mining process, 80% could also be potentially unsafe (i.e. 80% of blocks signaling might have a good chance of coming from only 60% of miners), so a threshold of 95% was considered "safe enough for Bitcoin work".
Why have a timeout that disables the upgrade?
Before BIP9, what was used was either flag day or BIP34. BIP34 had no flag day of activation or a bit, instead, it was just a 95% threshold to signal an nVersion value greater than a specific value. Actually, it was two thresholds: at 75%, blocks with the new nVersion would have the new softfork rules imposed, but at 95% blocks with the old nVersion would be rejected (and only the new blocks, with the new softfork rules, were accepted). For one, between 75% and 95%, there was a situation where the softfork was only "partially imposed", only blocks signaling the new rules would actually have those rules, but blocks with the old rules were still valid. This was fine for BIP34, which only added rules for miners with negligible use for non-miners.
The reasons miners signalled support was because they felt they were being pressured to signal support. So they signalled support, with plans to actually upgrade later, but because of the widespread signalling, the new BIP66 version locked in before upgrade plans were finished. Thus, the timeout that disables the upgrade was added in BIP9 to allow miners an escape hatch.
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.
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.
Overt ASICBoost - Manipulates the unused bits in nVersion to reduce power consumption in mining.
Covert ASICBoost - Manipulates the order of transactions in the block to reduce power consumption in mining.
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:
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.
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.
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.
First have a 12-month BIP9 (fail at timeout).
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.
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:
You hear a new version of your favorite software has a nice new feature.
Excited, you install the new version.
You find that the new version has subtle incompatibilities with your current workflow.
You are sad and downgrade to the older version.
You find out that the new version has changed your files in incompatible ways that the old version cannot work with anymore.
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:
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.
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.
Maybe it's time to discuss bitcoin's history again. Credit to u/singularity87 for the original post over 3 years ago. People should get the full story of bitcoin because it is probably one of the strangest of all reddit subs. bitcoin, the main sub for the bitcoin community is held and run by a person who goes by the pseudonym u/theymos. Theymos not only controls bitcoin, but also bitcoin.org and bitcointalk.com. These are top three communication channels for the bitcoin community, all controlled by just one person. For most of bitcoin's history this did not create a problem (at least not an obvious one anyway) until around mid 2015. This happened to be around the time a new player appeared on the scene, a for-profit company called Blockstream. Blockstream was made up of/hired many (but not all) of the main bitcoin developers. (To be clear, Blockstream was founded before mid 2015 but did not become publicly active until then). A lot of people, including myself, tried to point out there we're some very serious potential conflicts of interest that could arise when one single company controls most of the main developers for the biggest decentralised and distributed cryptocurrency. There were a lot of unknowns but people seemed to give them the benefit of the doubt because they were apparently about to release some new software called "sidechains" that could offer some benefits to the network. Not long after Blockstream came on the scene the issue of bitcoin's scalability once again came to forefront of the community. This issue came within the community a number of times since bitcoins inception. Bitcoin, as dictated in the code, cannot handle any more than around 3 transactions per second at the moment. To put that in perspective Paypal handles around 15 transactions per second on average and VISA handles something like 2000 transactions per second. The discussion in the community has been around how best to allow bitcoin to scale to allow a higher number of transactions in a given amount of time. I suggest that if anyone is interested in learning more about this problem from a technical angle, they go to btc and do a search. It's a complex issue but for many who have followed bitcoin for many years, the possible solutions seem relatively obvious. Essentially, currently the limit is put in place in just a few lines of code. This was not originally present when bitcoin was first released. It was in fact put in place afterwards as a measure to stop a bloating attack on the network. Because all bitcoin transactions have to be stored forever on the bitcoin network, someone could theoretically simply transmit a large number of transactions which would have to be stored by the entire network forever. When bitcoin was released, transactions were actually for free as the only people running the network were enthusiasts. In fact a single bitcoin did not even have any specific value so it would be impossible set a fee value. This meant that a malicious person could make the size of the bitcoin ledger grow very rapidly without much/any cost which would stop people from wanting to join the network due to the resource requirements needed to store it, which at the time would have been for very little gain. Towards the end of the summer last year, this bitcoin scaling debate surfaced again as it was becoming clear that the transaction limit for bitcoin was semi regularly being reached and that it would not be long until it would be regularly hit and the network would become congested. This was a very serious issue for a currency. Bitcoin had made progress over the years to the point of retailers starting to offer it as a payment option. Bitcoin companies like, Microsoft, Paypal, Steam and many more had began to adopt it. If the transaction limit would be constantly maxed out, the network would become unreliable and slow for users. Users and businesses would not be able to make a reliable estimate when their transaction would be confirmed by the network. Users, developers and businesses (which at the time was pretty much the only real bitcoin subreddit) started to discuss how we should solve the problem bitcoin. There was significant support from the users and businesses behind a simple solution put forward by the developer Gavin Andreesen. Gavin was the lead developer after Satoshi Nakamoto left bitcoin and he left it in his hands. Gavin initially proposed a very simple solution of increasing the limit which was to change the few lines of code to increase the maximum number of transactions that are allowed. For most of bitcoin's history the transaction limit had been set far far higher than the number of transactions that could potentially happen on the network. The concept of increasing the limit one time was based on the fact that history had proven that no issue had been cause by this in the past. A certain group of bitcoin developers decided that increasing the limit by this amount was too much and that it was dangerous. They said that the increased use of resources that the network would use would create centralisation pressures which could destroy the network. The theory was that a miner of the network with more resources could publish many more transactions than a competing small miner could handle and therefore the network would tend towards few large miners rather than many small miners. The group of developers who supported this theory were all developers who worked for the company Blockstream. The argument from people in support of increasing the transaction capacity by this amount was that there are always inherent centralisation pressure with bitcoin mining. For example miners who can access the cheapest electricity will tend to succeed and that bigger miners will be able to find this cheaper electricity easier. Miners who have access to the most efficient computer chips will tend to succeed and that larger miners are more likely to be able to afford the development of them. The argument from Gavin and other who supported increasing the transaction capacity by this method are essentially there are economies of scale in mining and that these economies have far bigger centralisation pressures than increased resource cost for a larger number of transactions (up to the new limit proposed). For example, at the time the total size of the blockchain was around 50GB. Even for the cost of a 500GB SSD is only $150 and would last a number of years. This is in-comparison to the $100,000's in revenue per day a miner would be making. Various developers put forth various other proposals, including Gavin Andresen who put forth a more conservative increase that would then continue to increase over time inline with technological improvements. Some of the employees of blockstream also put forth some proposals, but all were so conservative, it would take bitcoin many decades before it could reach a scale of VISA. Even though there was significant support from the community behind Gavin's simple proposal of increasing the limit it was becoming clear certain members of the bitcoin community who were part of Blockstream were starting to become increasingly vitriolic and divisive. Gavin then teamed up with one of the other main bitcoin developers Mike Hearn and released a coded (i.e. working) version of the bitcoin software that would only activate if it was supported by a significant majority of the network. What happened next was where things really started to get weird. After this free and open source software was released, Theymos, the person who controls all the main communication channels for the bitcoin community implemented a new moderation policy that disallowed any discussion of this new software. Specifically, if people were to discuss this software, their comments would be deleted and ultimately they would be banned temporarily or permanently. This caused chaos within the community as there was very clear support for this software at the time and it seemed our best hope for finally solving the problem and moving on. Instead a censorship campaign was started. At first it 'all' they were doing was banning and removing discussions but after a while it turned into actively manipulating the discussion. For example, if a thread was created where there was positive sentiment for increasing the transaction capacity or being negative about the moderation policies or negative about the actions of certain bitcoin developers, the mods of bitcoin would selectively change the sorting order of threads to 'controversial' so that the most support opinions would be sorted to the bottom of the thread and the most vitriolic would be sorted to the top of the thread. This was initially very transparent as it was possible to see that the most downvoted comments were at the top and some of the most upvoted were at the bottom. So they then implemented hiding the voting scores next to the users name. This made impossible to work out the sentiment of the community and when combined with selectively setting the sorting order to controversial it was possible control what information users were seeing. Also, due to the very very large number of removed comments and users it was becoming obvious the scale of censorship going on. To hide this they implemented code in their CSS for the sub that completely hid comments that they had removed so that the censorship itself was hidden. Anyone in support of scaling bitcoin were removed from the main communication channels. Theymos even proudly announced that he didn't care if he had to remove 90% of the users. He also later acknowledged that he knew he had the ability to block support of this software using the control he had over the communication channels. While this was all going on, Blockstream and it's employees started lobbying the community by paying for conferences about scaling bitcoin, but with the very very strange rule that no decisions could be made and no complete solutions could be proposed. These conferences were likely strategically (and successfully) created to stunt support for the scaling software Gavin and Mike had released by forcing the community to take a "lets wait and see what comes from the conferences" kind of approach. Since no final solutions were allowed at these conferences, they only served to hinder and splinter the communities efforts to find a solution. As the software Gavin and Mike released called BitcoinXT gained support it started to be attacked. Users of the software were attack by DDOS. Employees of Blockstream were recommending attacks against the software, such as faking support for it, to only then drop support at the last moment to put the network in disarray. Blockstream employees were also publicly talking about suing Gavin and Mike from various different angles simply for releasing this open source software that no one was forced to run. In the end Mike Hearn decided to leave due to the way many members of the bitcoin community had treated him. This was due to the massive disinformation campaign against him on bitcoin. One of the many tactics that are used against anyone who does not support Blockstream and the bitcoin developers who work for them is that you will be targeted in a smear campaign. This has happened to a number of individuals and companies who showed support for scaling bitcoin. Theymos has threatened companies that he will ban any discussion of them on the communication channels he controls (i.e. all the main ones) for simply running software that he disagrees with (i.e. any software that scales bitcoin). As time passed, more and more proposals were offered, all against the backdrop of ever increasing censorship in the main bitcoin communication channels. It finally come down the smallest and most conservative solution. This solution was much smaller than even the employees of Blockstream had proposed months earlier. As usual there was enormous attacks from all sides and the most vocal opponents were the employees of Blockstream. These attacks still are ongoing today. As this software started to gain support, Blockstream organised more meetings, especially with the biggest bitcoin miners and made a pact with them. They promised that they would release code that would offer an on-chain scaling solution hardfork within about 4 months, but if the miners wanted this they would have to commit to running their software and only their software. The miners agreed and the ended up not running the most conservative proposal possible. This was in February last year. There is no hardfork proposal in sight from the people who agreed to this pact and bitcoin is still stuck with the exact same transaction limit it has had since the limit was put in place about 6 years ago. Gavin has also been publicly smeared by the developers at Blockstream and a plot was made against him to have him removed from the development team. Gavin has now been, for all intents an purposes, expelled from bitcoin development. This has meant that all control of bitcoin development is in the hands of the developers working at Blockstream. There is a new proposal that offers a market based approach to scaling bitcoin. This essentially lets the market decide. Of course, as usual there has been attacks against it, and verbal attacks from the employees of Blockstream. This has the biggest chance of gaining wide support and solving the problem for good. To give you an idea of Blockstream; It has hired most of the main and active bitcoin developers and is now synonymous with the "Core" bitcoin development team. They AFAIK no products at all. They have received around $75m in funding. Every single thing they do is supported by theymos. They have started implementing an entirely new economic system for bitcoin against the will of it's users and have blocked any and all attempts to scaling the network in line with the original vision. Although this comment is ridiculously long, it really only covers the tip of the iceberg. You could write a book on the last two years of bitcoin. The things that have been going on have been mind blowing. One last thing that I think is worth talking about is the u/bashco's claim of vote manipulation. The users that the video talks about have very very large numbers of downvotes mostly due to them having a very very high chance of being astroturfers. Around about the same time last year when Blockstream came active on the scene every single bitcoin troll disappeared, and I mean literally every single one. In the years before that there were a large number of active anti-bitcoin trolls. They even have an active sub buttcoin. Up until last year you could go down to the bottom of pretty much any thread in bitcoin and see many of the usual trolls who were heavily downvoted for saying something along the lines of "bitcoin is shit", "You guys and your tulips" etc. But suddenly last year they all disappeared. Instead a new type of bitcoin user appeared. Someone who said they were fully in support of bitcoin but they just so happened to support every single thing Blockstream and its employees said and did. They had the exact same tone as the trolls who had disappeared. Their way to talking to people was aggressive, they'd call people names, they had a relatively poor understanding of how bitcoin fundamentally worked. They were extremely argumentative. These users are the majority of the list of that video. When the 10's of thousands of users were censored and expelled from bitcoin they ended up congregating in btc. The strange thing was that the users listed in that video also moved over to btc and spend all day everyday posting troll-like comments and misinformation. Naturally they get heavily downvoted by the real users in btc. They spend their time constantly causing as much drama as possible. At every opportunity they scream about "censorship" in btc while they are happy about the censorship in bitcoin. These people are astroturfers. What someone somewhere worked out, is that all you have to do to take down a community is say that you are on their side. It is an astoundingly effective form of psychological attack.
This is a follow-up on https://old.reddit.com/Bitcoin/comments/hqzp14/technical_the_path_to_taproot_activation/ Taproot! Everybody wants it!! But... you might ask yourself: sure, everybody else wants it, but why would I, sovereign Bitcoin HODLer, want it? Surely I can be better than everybody else because I swapped XXX fiat for Bitcoin unlike all those nocoiners? And it is important for you to know the reasons why you, o sovereign Bitcoiner, would want Taproot activated. After all, your nodes (or the nodes your wallets use, which if you are SPV, you hopefully can pester to your wallet vendoimplementor about) need to be upgraded in order for Taproot activation to actually succeed instead of becoming a hot sticky mess. First, let's consider some principles of Bitcoin.
You the HODLer should be the one who controls where your money goes. Your keys, your coins.
You the HODLer should be able to coordinate and make contracts with other people regarding your funds.
You the HODLer should be able to do the above without anyone watching over your shoulder and judging you.
I'm sure most of us here would agree that the above are very important principles of Bitcoin and that these are principles we would not be willing to remove. If anything, we would want those principles strengthened (especially the last one, financial privacy, which current Bitcoin is only sporadically strong with: you can get privacy, it just requires effort to do so). So, how does Taproot affect those principles?
Taproot and Your /Coins
Most HODLers probably HODL their coins in singlesig addresses. Sadly, switching to Taproot would do very little for you (it gives a mild discount at spend time, at the cost of a mild increase in fee at receive time (paid by whoever sends to you, so if it's a self-send from a P2PKH or bech32 address, you pay for this); mostly a wash). (technical details: a Taproot output is 1 version byte + 32 byte public key, while a P2WPKH (bech32 singlesig) output is 1 version byte + 20 byte public key hash, so the Taproot output spends 12 bytes more; spending from a P2WPKH requires revealing a 32-byte public key later, which is not needed with Taproot, and Taproot signatures are about 9 bytes smaller than P2WPKH signatures, but the 32 bytes plus 9 bytes is divided by 4 because of the witness discount, so it saves about 11 bytes; mostly a wash, it increases blockweight by about 1 virtual byte, 4 weight for each Taproot-output-input, compared to P2WPKH-output-input). However, as your HODLings grow in value, you might start wondering if multisignature k-of-n setups might be better for the security of your savings. And it is in multisignature that Taproot starts to give benefits! Taproot switches to using Schnorr signing scheme. Schnorr makes key aggregation -- constructing a single public key from multiple public keys -- almost as trivial as adding numbers together. "Almost" because it involves some fairly advanced math instead of simple boring number adding, but hey when was the last time you added up your grocery list prices by hand huh? With current P2SH and P2WSH multisignature schemes, if you have a 2-of-3 setup, then to spend, you need to provide two different signatures from two different public keys. With Taproot, you can create, using special moon math, a single public key that represents your 2-of-3 setup. Then you just put two of your devices together, have them communicate to each other (this can be done airgapped, in theory, by sending QR codes: the software to do this is not even being built yet, but that's because Taproot hasn't activated yet!), and they will make a single signature to authorize any spend from your 2-of-3 address. That's 73 witness bytes -- 18.25 virtual bytes -- of signatures you save! And if you decide that your current setup with 1-of-1 P2PKH / P2WPKH addresses is just fine as-is: well, that's the whole point of a softfork: backwards-compatibility; you can receive from Taproot users just fine, and once your wallet is updated for Taproot-sending support, you can send to Taproot users just fine as well! (P2WPKH and P2WSH -- SegWit v0 -- addresses start with bc1q; Taproot -- SegWit v1 --- addresses start with bc1p, in case you wanted to know the difference; in bech32 q is 0, p is 1) Now how about HODLers who keep all, or some, of their coins on custodial services? Well, any custodial service worth its salt would be doing at least 2-of-3, or probably something even bigger, like 11-of-15. So your custodial service, if it switched to using Taproot internally, could save a lot more (imagine an 11-of-15 getting reduced from 11 signatures to just 1!), which --- we can only hope! --- should translate to lower fees and better customer service from your custodial service! So I think we can say, very accurately, that the Bitcoin principle --- that YOU are in control of your money --- can only be helped by Taproot (if you are doing multisignature), and, because P2PKH and P2WPKH remain validly-usable addresses in a Taproot future, will not be harmed by Taproot. Its benefit to this principle might be small (it mostly only benefits multisignature users) but since it has no drawbacks with this (i.e. singlesig users can continue to use P2WPKH and P2PKH still) this is still a nice, tidy win! (even singlesig users get a minor benefit, in that multisig users will now reduce their blockchain space footprint, so that fees can be kept low for everybody; so for example even if you have your single set of private keys engraved on titanium plates sealed in an airtight box stored in a safe buried in a desert protected by angry nomads riding giant sandworms because you're the frickin' Kwisatz Haderach, you still gain some benefit from Taproot) And here's the important part: if P2PKH/P2WPKH is working perfectly fine with you and you decide to never use Taproot yourself, Taproot will not affect you detrimentally. First do no harm!
Taproot and Your Contracts
No one is an island, no one lives alone. Give and you shall receive. You know: by trading with other people, you can gain expertise in some obscure little necessity of the world (and greatly increase your productivity in that little field), and then trade the products of your expertise for necessities other people have created, all of you thereby gaining gains from trade. So, contracts, which are basically enforceable agreements that facilitate trading with people who you do not personally know and therefore might not trust. Let's start with a simple example. You want to buy some gewgaws from somebody. But you don't know them personally. The seller wants the money, you want their gewgaws, but because of the lack of trust (you don't know them!! what if they're scammers??) neither of you can benefit from gains from trade. However, suppose both of you know of some entity that both of you trust. That entity can act as a trusted escrow. The entity provides you security: this enables the trade, allowing both of you to get gains from trade. In Bitcoin-land, this can be implemented as a 2-of-3 multisignature. The three signatories in the multisgnature would be you, the gewgaw seller, and the escrow. You put the payment for the gewgaws into this 2-of-3 multisignature address. Now, suppose it turns out neither of you are scammers (whaaaat!). You receive the gewgaws just fine and you're willing to pay up for them. Then you and the gewgaw seller just sign a transaction --- you and the gewgaw seller are 2, sufficient to trigger the 2-of-3 --- that spends from the 2-of-3 address to a singlesig the gewgaw seller wants (or whatever address the gewgaw seller wants). But suppose some problem arises. The seller gave you gawgews instead of gewgaws. Or you decided to keep the gewgaws but not sign the transaction to release the funds to the seller. In either case, the escrow is notified, and if it can sign with you to refund the funds back to you (if the seller was a scammer) or it can sign with the seller to forward the funds to the seller (if you were a scammer). Taproot helps with this: like mentioned above, it allows multisignature setups to produce only one signature, reducing blockchain space usage, and thus making contracts --- which require multiple people, by definition, you don't make contracts with yourself --- is made cheaper (which we hope enables more of these setups to happen for more gains from trade for everyone, also, moon and lambos). (technology-wise, it's easier to make an n-of-n than a k-of-n, making a k-of-n would require a complex setup involving a long ritual with many communication rounds between the n participants, but an n-of-n can be done trivially with some moon math. You can, however, make what is effectively a 2-of-3 by using a three-branch SCRIPT: either 2-of-2 of you and seller, OR 2-of-2 of you and escrow, OR 2-of-2 of escrow and seller. Fortunately, Taproot adds a facility to embed a SCRIPT inside a public key, so you can have a 2-of-2 Taprooted address (between you and seller) with a SCRIPT branch that can instead be spent with 2-of-2 (you + escrow) OR 2-of-2 (seller + escrow), which implements the three-branched SCRIPT above. If neither of you are scammers (hopefully the common case) then you both sign using your keys and never have to contact the escrow, since you are just using the escrow public key without coordinating with them (because n-of-n is trivial but k-of-n requires setup with communication rounds), so in the "best case" where both of you are honest traders, you also get a privacy boost, in that the escrow never learns you have been trading on gewgaws, I mean ewww, gawgews are much better than gewgaws and therefore I now judge you for being a gewgaw enthusiast, you filthy gewgawer).
Taproot and Your Contracts, Part 2: Cryptographic Boogaloo
Now suppose you want to buy some data instead of things. For example, maybe you have some closed-source software in trial mode installed, and want to pay the developer for the full version. You want to pay for an activation code. This can be done, today, by using an HTLC. The developer tells you the hash of the activation code. You pay to an HTLC, paying out to the developer if it reveals the preimage (the activation code), or refunding the money back to you after a pre-agreed timeout. If the developer claims the funds, it has to reveal the preimage, which is the activation code, and you can now activate your software. If the developer does not claim the funds by the timeout, you get refunded. And you can do that, with HTLCs, today. Of course, HTLCs do have problems:
Privacy. Everyone scraping the Bitcoin blockchain can see any HTLCs, and preimages used to claim them.
This can be mitigated by using offchain techniques so HTLCs are never published onchain in the happy case. Lightning would probably in practice be the easiest way to do this offchain. Of course, there are practical limits to what you can pay on Lightning. If you are buying something expensive, then Lightning might not be practical. For example, the "software" you are activating is really the firmware of a car, and what you are buying is not the software really but the car itself (with the activation of the car firmware being equivalent to getting the car keys).
Even offchain techniques need an onchain escape hatch in case of unresponsiveness! This means that, if something bad happens during payment, the HTLC might end up being published onchain anyway, revealing the fact that some special contract occurred.
And an HTLC that is claimed with a preimage onchain will also publicly reveal the preimage onchain. If that preimage is really the activation key of a software than it can now be pirated. If that preimage is really the activation key for your newly-bought cryptographic car --- well, not your keys, not your car!
Trust requirement. You are trusting the developer that it gives you the hash of an actual valid activation key, without any way to validate that the activation key hidden by the hash is actually valid.
Fortunately, with Schnorr (which is enabled by Taproot), we can now use the Scriptless Script constuction by Andrew Poelstra. This Scriptless Script allows a new construction, the PTLC or Pointlocked Timelocked Contract. Instead of hashes and preimages, just replace "hash" with "point" and "preimage" with "scalar". Or as you might know them: "point" is really "public key" and "scalar" is really a "private key". What a PTLC does is that, given a particular public key, the pointlocked branch can be spent only if the spender reveals the private key of the given private key to you. Another nice thing with PTLCs is that they are deniable. What appears onchain is just a single 2-of-2 signature between you and the developemanufacturer. It's like a magic trick. This signature has no special watermarks, it's a perfectly normal signature (the pledge). However, from this signature, plus some datta given to you by the developemanufacturer (known as the adaptor signature) you can derive the private key of a particular public key you both agree on (the turn). Anyone scraping the blockchain will just see signatures that look just like every other signature, and as long as nobody manages to hack you and get a copy of the adaptor signature or the private key, they cannot get the private key behind the public key (point) that the pointlocked branch needs (the prestige). (Just to be clear, the public key you are getting the private key from, is distinct from the public key that the developemanufacturer will use for its funds. The activation key is different from the developer's onchain Bitcoin key, and it is the activation key whose private key you will be learning, not the developer's/manufacturer's onchain Bitcoin key). So:
Privacy: PTLCs are private even if done onchain. Nobody else can learn what the private key behind the public key is, except you who knows the adaptor signature that when combined with the complete onchain signature lets you know what the private key of the activation key is. Somebody scraping the blockchain will not learn the same information even if all PTLCs are done onchain!
Lightning is still useful for reducing onchain use, and will also get PTLCs soon after Taproot is activated, but even if something bad happens and a PTLC has to go onchain, it doesn't reveal anything!
Trust issues can be proven more easily with a public-private keypair than with a hash-preimage pair.
For example, the developer of the software you are buying could provide a signature signing a message saying "unlock access to the full version for 1 day". You can check if feeding this message and signature to the program will indeed unlock full-version access for 1 day. Then you can check if the signature is valid for the purported pubkey whose private key you will pay for. If so, you can now believe that getting the private key (by paying for it in a PTLC) would let you generate any number of "unlock access to the full version for 1 day" message+signatures, which is equivalent to getting full access to the software indefinitely.
For the car, the manufacturer can show that signing a message "start the engine" and feeding the signature to the car's fimrware will indeed start the engine, and maybe even let you have a small test drive. You can then check if the signature is valid for the purported pubkey whose privkey you will pay for. If so, you can now believe that gaining knowledge of the privkey will let you start the car engine at any time you want.
(pedantry: the signatures need to be unique else they could be replayed, this can be done with a challenge-response sequence for the car, where the car gathers entropy somehow (it's a car, it probably has a bunch of sensors nowadays so it can get entropy for free) and uses the gathered entropy to challenge you to sign a random number and only start if you are able to sign the random number; for the software, it could record previous signatures somewhere in the developer's cloud server and refuse to run if you try to replay a previously-seen signature.)
Taproot lets PTLCs exist onchain because they enable Schnorr, which is a requirement of PTLCs / Scriptless Script. (technology-wise, take note that Scriptless Script works only for the "pointlocked" branch of the contract; you need normal Script, or a pre-signed nLockTimed transaction, for the "timelocked" branch. Since Taproot can embed a script, you can have the Taproot pubkey be a 2-of-2 to implement the Scriptless Script "pointlocked" branch, then have a hidden script that lets you recover the funds with an OP_CHECKLOCKTIMEVERIFY after the timeout if the seller does not claim the funds.)
Now if you were really paying attention, you might have noticed this parenthetical:
(technical details: a Taproot output is 1 version byte + 32 byte public key, while a P2WPKH (bech32 singlesig) output is 1 version byte + 20 byte public key hash...)
So wait, Taproot uses raw 32-byte public keys, and not public key hashes? Isn't that more quantum-vulnerable?? Well, in theory yes. In practice, they probably are not. It's not that hashes can be broken by quantum computes --- they're still not. Instead, you have to look at how you spend from a P2WPKH/P2PKH pay-to-public-key-hash. When you spend from a P2PKH / P2WPKH, you have to reveal the public key. Then Bitcoin hashes it and checks if this matches with the public-key-hash, and only then actually validates the signature for that public key. So an unconfirmed transaction, floating in the mempools of nodes globally, will show, in plain sight for everyone to see, your public key. (public keys should be public, that's why they're called public keys, LOL) And if quantum computers are fast enough to be of concern, then they are probably fast enough that, in the several minutes to several hours from broadcast to confirmation, they have already cracked the public key that is openly broadcast with your transaction. The owner of the quantum computer can now replace your unconfirmed transaction with one that pays the funds to itself. Even if you did not opt-in RBF, miners are still incentivized to support RBF on RBF-disabled transactions. So the extra hash is not as significant a protection against quantum computers as you might think. Instead, the extra hash-and-compare needed is just extra validation effort. Further, if you have ever, in the past, spent from the address, then there exists already a transaction indelibly stored on the blockchain, openly displaying the public key from which quantum computers can derive the private key. So those are still vulnerable to quantum computers. For the most part, the cryptographers behind Taproot (and Bitcoin Core) are of the opinion that quantum computers capable of cracking Bitcoin pubkeys are unlikely to appear within a decade or two.
Current quantum computers can barely crack prime factorization problem for primes of 5 bits.
The 256-bit elliptic curve use by Bitcoin is, by my (possibly wrong) understanding, equivalent to 4096-bit primes, so you can see a pretty big gap between now (5 bit primes) and what is needed (4096 bit primes).
A lot of financial non-Bitcoin systems use the equivalent of 3072-bit primes or less, and are probably easier targets to crack than the equivalent-to-4096-bit-primes Bitcoin.
Quantum computers capable of cracking Bitcoin are still far off.
Pay-to-public-key-hash is not as protective as you might think.
We will probably see banks get cracked before Bitcoin, so the banking system is a useful canary-in-a-coal-mine to see whether we should panic about being quantum vulnerable.
For now, the homomorphic and linear properties of elliptic curve cryptography provide a lot of benefits --- particularly the linearity property is what enables Scriptless Script and simple multisignature (i.e. multisignatures that are just 1 signature onchain). So it might be a good idea to take advantage of them now while we are still fairly safe against quantum computers. It seems likely that quantum-safe signature schemes are nonlinear (thus losing these advantages).
If you are a singlesig HODL-only Bitcoin user, Taproot will not affect you positively or negatively. Importantly: Taproot does no harm!
If you use or intend to use multisig, Taproot will be a positive for you.
If you transact onchain regularly using typical P2PKH/P2WPKH addresses, you get a minor reduction in feerates since multisig users will likely switch to Taproot to get smaller tx sizes, freeing up blockspace for yours.
If you are using multiparticipant setups for special systems of trade, Taproot will be a positive for you.
Remember: Lightning channels are multipartiicpiant setups for special systems of lightning-fast offchain trades!
I Wanna Be The Taprooter!
So, do you want to help activate Taproot? Here's what you, mister sovereign Bitcoin HODLer, can do!
If you have developer experience especially in C, C++, or related languages
Review the Taproot code! There is one pull request in Bitcoin Core, and one in libsecp256k1. I deliberately am not putting links here, to avoid brigades of nontechnical but enthusiastic people leaving pointless reviews, but if you are qualified you know how to find them!
But I am not a cryptographeBitcoin Core contributomathematician/someone as awesome as Pieter Wuille
That's perfectly fine! The cryptographers have been over the code already and agree the math is right and the implementation is right. What is wanted is the dreary dreary dreary software engineering: are the comments comprehensive and understandable? no misspellings in the comments? variable names understandable? reasonable function naming convention? misleading coding style? off-by-one errors in loops? conditions not covered by tests? accidental mixups of variables with the same types? missing frees? read-before-init? better test coverage of suspicious-looking code? missing or mismatching header guards? portability issues? consistent coding style? you know, stuff any coder with a few years of experience in coding anything might be able to catch. With enough eyes all bugs are shallow!
If you are running a mining pool/mining operation/exchange/custodial service/SPV server
Be prepared to upgrade!
One of the typical issues with upgrading software is that subtle incompatibilities with your current custom programs tend to arise, disrupting operations and potentially losing income due to downtime. If so, consider moving to the two-node setup suggested by gmax, which is in the last section of my previous post. With this, you have an up-to-date "public" node and a fixed-version "private" node, with the public node protecting the private node from any invalid chainsplits or invalid transactions. Moving to this setup from a typical one-node setup should be smooth and should not disrupt operations (too much).
If you are running your own fullnode for fun or for your own wallet
Be prepared to upgrade! The more nodes validating the new rules (even if you are a non-mining node!), the safer every softfork will be!
If you are using an SPV wallet or custodial wallet/service (including hardware wallets using the software of the wallet provider)
Contact your wallet provider / SPV server and ask for a statement on whether they support Taproot, and whether they are prepared to upgrade for Taproot! Make it known to them that Taproot is something you want!
But I Hate Taproot!!
Raise your objections to Taproot now, or forever hold your peace! Maybe you can raise them here and some of the devs (probably nullc, he goes everywhere, even in rbtc!) might be able to see your objections! Or if your objections are very technical, head over to the appropriate pull request and object away!
Maybe you simply misunderstand something, and we can clarify it here!
Or maybe you do have a good objection, and we can make Taproot better by finding a solution for it!
I keep hearing "Deflation before massive inflation"
So what can we do about it? Any ideas are welcome. It has a lot of "what if's"... It depends how tax and law play out with it.Historically speaking:
Commodities and things people use every day become expensive,
Luxury goods fall in value.
Inflation wipes out all savings, there is often a rush to spend money while it has value. "Bank runs" and "Bank Bail in's" where the bank will limit your withdraws to prop up the bank temporarily. Sure here the FDIC may insure it, but its nothing if your money is losing value by the hour and it takes months to get it actually into your hands. And many countries have issues with a person holding cash..."You're automatically a drug dealer! >your money is now drug money! >Asset forfeiture" ...I cant count how many times this happens.
People yell " physical gold and silver!" ... yeah, those do hold value well, however the gov does tax that at 26-30% when sold, and will often ban its use in dire times. ....huge grey / pirate area.
Mining stock is the same in the tax range, and nearly anything you "resell", imposed taxes and royalties can be added leaving you high and dry.
Precious metal holdings have been banned in the past, even here in the USA...aka Government confiscation.
Nationalization of Precious metals mines have happened.
Edit: I now realize there are many ways stocks can play out.
Real Estate will raise in value hugely, However so will the taxes, longer contracts at fixed rates benefits the lendee.
Things that you use, if you can stock or invest in it.
-I stock bulk diesel for my cars while following historical averages to buy cheap.
-Rotating food stock
-Extra maintenance items, including the big things like a roof on your home if its coming time. Not joking I have a spare water heater and backup heating options, along with minor parts and filters to fix them. Same with cars and engines, (spark plugs, filters (all different filters), oil, cheap sensors that usually go bad and are only 4-10$ each, 1-2 extra alternator per vehicle, belts, mowing belts, bearings, grease, ... and I've literally had to use everything on that list and reorder.)
Things that directly pay you back or are insurance. Saving money is making money.
-Security, Locks, Alarms, Cameras, people steal.
A deep freezer for instance can stock food you use and buy on sale.
Solar energy and solar heating supplements energy you use anyways
Rainwater can be collected and used rather than buying from a source.
A cooking gadget vs eating out.
Tools and learning to fix things vs hire.
House insulation.-Better insulative windows, and sealing.
Bidet on toilet (lol serious though...)
Your education can be a huge one, not just for prepping but also in your work.
Things that prevent rot, fire, flood / humidity, or failure. Humidity is a silent killer to many preps. (water sump pumps, dehumidifiers, leak prevention, fire extinguishers / sprinklers, )
Things that last and can be resold on the street if need be. This list can be huge, you have to balance it with liquidity, what you use but can also sell before it goes bad / fails.
Honestly and unpopularly, Things that can avoid tax when the price inflates out of control and you wish to sell. The numbers can be so distorted in both price and taxing of income. Eggs for instance, in many countries from Weimar Republic of Germany to Venezuela, increased 15,000%+, So that $15,000 egg / $150,000 dozen that you sold from your chickens gets taxed in the highest tax bracket? (which can go into the 90% range if rules aren't changed for the massive inflation) Taxes usually try raising during this and many companies flee the country, add robots / machines, or downsize as the result of more taxes making work and jobs even more of an issue. .. honestly history shows the whole thing being a cluster-duck in so many ways. Alternative currencies pop up, actual trades happen and go unreported, crime even shifts when things get too bad, again with Venezuela, I read that criminals were moving to other countries because the people were too poor to even make anything robbing! You can also have a business where you write off so many things that you would use anyways. The numbers get... err... odd, play the game.
It is usually around 10 years of chaos before things start "stabilizing." and even then, so much damage has occured.
This is a serious thing that has happened to once prosperous people / civilizations in the past...don't think you're exempt, especially when the numbers are at historical limits in many countries. Invest in yourself and what you use regularly.
/r/Monero Weekly Discussion – July 11, 2020 - Use this thread for general chatter, basic questions, and if you're new to Monero
Wallet: CLI & GUI
1. General questions
Where can I download the Monero wallet?
There are multiple Monero wallets for a wide range of devices at your disposal. Check the table below for details and download links. Attention: for extra security make sure to calculate and compare the checksum of your downloaded files when possible. Please note the following usage of the labels: ⚠️ - Relatively new and/or beta. Use wallet with caution. ☢️ - Closed source.
"Official" GUI / CLI
Windows, macOS, Linux
Default implementation maintained by the core team. Use this wallet to run a full node and obtain maximum privacy. Integrates with hardware wallets. Current version: 0.15.0.1 / 0.15.0.4.
Your balance is unlocked after 10 confirmations (which means 10 mined blocks). A block is mined approximately every two minutes on the Monero network, so that would be around 20 minutes.
How can I prove that I sent a payment?
The fastest and most direct way is by using the ExploreMonero blockchain explorer. You will need to recover the transaction key from your wallet (complete guide for GUI / CLI).
How do I buy Monero (XMR) with Bitcoin (BTC)?
There are dozens of exchanges that trade Monero against Bitcoin and other cryptocurrencies. Check out the list on CoinMarketCap and choose the option that suits you best.
How do I buy Monero (XMR) with fiat?
Kraken (USD and EUR): old-school, decent exchange. They might require your documents for verification and approval of your account.
LocalMonero: peer-to-peer exchange. They have pretty much everything as a payment method and they support hundreds of fiat options.
How can I quickly exchange my Monero (XMR) for Bitcoin (BTC)?
There are multiple ways to exchange your Monero for Bitcoin, but first of all, I'd like to remind you that if you really want to do your part for Monero, one of the simplest ways is to get in touch with your merchant/service provider and request for it to accept Monero directly as payment. Ask the service provider to visit the official website and our communication channels if he or she needs help with system integration. That being said, the community has been recommending two services in particular, XMR.TO and MorphToken. These services are only recommendations and are operated by entities outside the control of the Monero Project. Be diligent.
How do I mine Monero? And other mining questions.
The correct place to ask questions and discuss the Monero mining scene is in the dedicated subreddit MoneroMining. That being said, you can find a list of pools and available mining software in the GetMonero.org website.
2. Wallet: CLI & GUI
Why I can't see my balance? Where is my XMR?
Before any action there are two things to check:
Are you using the latest available version of the wallet? A new version is released roughly every 6 months, so make sure you're using the current release (compare the release on GetMonero.org with your wallet's version on Settings, under Debug info).
Is your wallet fully synchronized? If it isn't, wait the sync to complete.
Because Monero is different from Bitcoin, wallet synchronization is not instant. The software needs to synchronize the blockchain and use your private keys to identify your transactions. Check in the lower left corner (GUI) if the wallet is synchronized. You can't send transactions and your balance might be wrong or unavailable if the wallet is not synced with the network. So please wait. If this is not a sufficient answer for your case and you're looking for more information, please see this answer on StackExchange.
Why does it take so long to sync the wallet [for the first time]?
You have decided to use Monero's wallet and run a local node. Congratulations! You have chosen the safest and most secure option for your privacy, but unfortunately this has an initial cost. The first reason for the slowness is that you will need to download the entire blockchain, which is considerably heavy (+70 GB) and constantly growing. There are technologies being implemented in Monero to slow this growth, however it is inevitable to make this initial download to run a full node. Consider syncing to a device that has an SSD instead of an HDD, as this greatly impacts the speed of synchronization. Now that the blockchain is on your computer, the next time you run the wallet you only need to download new blocks, which should take seconds or minutes (depending on how often you use the wallet).
I don't want to download the blockchain, how can I skip that?
The way to skip downloading the blockchain is connecting your wallet to a public remote node. You can follow this guide on how to set it up. You can find a list of public remote nodes on MoneroWorld. Be advised that when using a public remote node you lose some of your privacy. A public remote node is able to identify your IP and opens up a range for certain attacks that further diminish your privacy.A remote node can't see your balance and it can't spend your XMR.
How do I restore my wallet from the mnemonic seed or from the keys?
To restore your wallet with the 25 word mnemonic seed, please see this guide. To restore your wallet with your keys, please see this guide.
