You’ll have observed a brand new development on bitcoin twitter these days, individuals altering their profile photos to some type of a Reuben sandwich. I’m going to clarify what this implies, why it is best to care and why it is best to take into account additionally turning into a Reuben sandwich. First I need to deal with one thing vital, the Rubin’s Reubens photographs should not NFTs, they aren’t inscriptions, they’re merely AI generated artwork that anybody can select to make use of without spending a dime.
The title comes from Jeremy Rubin (@JeremyRubin), the creator of OP_CTV and BIP119, and the likeness between Rubin and Reuben. Which you might have already discovered. So by having a Reuben sandwich as your profile image or by displaying the 🥪 emoji you’re signaling your assist for the CTV or extra lately LNHANCE improve proposals. LNHANCE, which was written by Brandon Black (@reardencode) is a mixture of OP_CTV, OP_CSFS and OP_INTERNALKEY. This mixture supplies a bit extra flexibility and programmability than simply OP_CTV alone, and permits further issues equivalent to LN symmetry/eltoo.
In a earlier article I defined that bitcoin has a scaling challenge and that covenants, together with CTV, generally is a answer to assist with this. Nevertheless I did not focus on the method concerned with how we truly activate these new OP codes. By design, it isn’t a fast or simple course of to comfortable fork bitcoin as a way to change the consensus guidelines. However what even is consensus? It is a robust query with loads of nuance, and the reply will rely on who you ask. Prior to now there was an idea of tough consensus, the place as soon as the change is effectively mentioned and there aren’t any extra affordable issues left to dispel relating to a proposal, you could have reached tough consensus. Some individuals imagine consensus is discovered when companies, equivalent to pockets suppliers, exchanges and miners agree on a change. And even simply the miners alone, as should you comfortable forked and not using a majority of miner hash assist, you’d be rejecting the blocks from the heavier chain, then will probably be as much as the market to determine which is the actual bitcoin. This may be very messy and complex, therefore it is a lot easier if you may get the miners on board with the improve. The fact is that the financial majority of bitcoin customers get to find out consensus, of which common customers, builders, miners, exchanges, wallets and different bitcoin holders all play a component. Measuring that is extremely tough, if not unattainable. Nevertheless you will need to attempt to decide the extent of consensus for a proposal earlier than trying to activate it.
In April 2022 Jeremy Rubin proposed a speedy trial activation of CTV, this didn’t go effectively, and led to the fork being very contentious. Speedy trial is the place the ultimate choice whether or not to activate a comfortable fork proposal or not, is given to the miners. Simply 5 months earlier taproot was activated utilizing the identical speedy trial methodology. Nevertheless many individuals felt it didn’t go effectively, they usually weren’t snug giving the miners the flexibility to say no to a change that will have majority consensus amongst the customers. A pair weeks after Jeremy introduced the speedy trial consumer he determined to name off the activation try. There was no consensus on CTV as a change in 2022. It’s value noting that Jeremy additionally launched a device for customers to withstand a CTV activation try (Consumer Resisted Softfork) with the activation consumer. So now 2 years later the group is one other activation try, however this time there will not be any speedy trial methodology.
So what are the choice methods to activate a comfortable fork? There are 2 BIPs (Bitcoin Enchancment Proposals) which can be used for activation, BIP8 and BIP9, I like to recommend studying these. Taproot used BIP9 for the speedy trial, which depends on timestamps to know the signaling durations. If the signaling interval ends with out reaching the activation threshold, then the try fails and there’s no comfortable fork. BIP8 makes use of block top to guage time durations and will be configured to both fail after a sign interval with out sufficient miner signaling, identical to BIP9. Or it may be configured to activate after the signaling interval, even with out reaching the edge. This parameter is named “lockinontimeout” or lot for brief, when set to true the comfortable fork will activate it doesn’t matter what. This pressured activation is named a UASF (Consumer Activated Delicate Fork), and might solely succeed long run if the vast majority of financial worth within the bitcoin ecosystem agrees with the change and upgrades their nodes. In any other case you will not find yourself on the heaviest chain, as miners will comply with the financial majority and never improve, however should you do have the financial majority supporting the change, miners must comply with them on account of financial incentives from the miners wishing to get essentially the most charges potential. Ideally the miners will sign sufficient assist earlier than the tip of the signaling interval, and the drama of a UASF will be prevented. It was the specter of UASF that brought on the miners in 2017 to comply with the Segwit improve and never enhance the blocksize just like the Bcashers wished. (Sure, technically the blocksize did nonetheless enhance a bit.)
We now have to briefly focus on activation parameters, these are the specifics of the activation, and consists of the next: the title; the model bit quantity; the beginning block top; the sign interval timeout block top; the minimal activation block top; the edge of blocks signaling; and eventually whether or not lockinontimeout is true or false. The title ought to typically simply be the BIP quantity, in CTVs case, BIP119. The model bit will be any that is not getting used already. The beginning is but to be decided, I’d hope it may be someday in 2024, nonetheless it is a group choice in the end. The sign interval timeout needs to be no less than 1 12 months after the beginning, some really feel 2 or extra years can be even higher, once more it is a group choice and the consumer developer should try to decide what the bulk agree with, I’d be pleased with 1 to 2 years of signaling interval. The minimal activation top is the earliest potential time that the comfortable fork might activate, this could possibly be earlier than the tip of the sign interval, concurrently the timeout or after the timeout. I imagine it needs to be no less than 6 months after the beginning top. The edge is what number of blocks in a 2 week problem interval, 2016 blocks, are required to activate via signaling. Usually that is 90 or 95% of the blocks, 1815-1915 blocks out of 2016. This implies 90/95% of the community’s hash energy have to be signaling assist for the improve in a 2 week interval. Lastly, as we already mentioned, lockinontimeout ought to most likely be set to true if you’d like the group to assist the activation try.
So how will we get to a degree of feeling assured we’ve got discovered consensus? Participating with the group, having conversations with bitcoin companies and repair suppliers, and signaling assist on-line in numerous methods. Rubin’s Reubens is one instance of this signaling, and it is a enjoyable and social means to take action. Do not be afraid to ask questions on something you do not perceive or agree with, bear in mind, we confirm round right here not simply belief. Have interaction along with your favorite bitcoin companies, ask them their opinion of CTV and you’ll want to allow them to know yours, in any case, you’re the buyer. In case you are a developer, you possibly can evaluate the code, or create a proof of idea for CTV. There’s presently over 5 BTC up for grabs should you can create a constructive proof of idea, or a damaging that’s dangerous, plus any bugs discovered when utilizing OP_CTV. This bounty has been round for greater than a 12 months already, with no one discovering any points. Yow will discover this bounty right here: https://bipbounty.org/bounties/1e101655-bad8-5147-82f7-f03145d567af/.
After all, in a decentralized system like bitcoin, we will by no means know for positive that the financial majority need a change, we will solely take a tough guess and hope for the very best. We cannot discover out till we attempt although. I imagine we’re both extraordinarily shut or have already discovered consensus for CTV. Be sure you head to utxos.org/alerts and add your title or enterprise to the checklist, you possibly can sign sure or no. Additionally, you will discover tons extra details about covenants on this web site.
