You could have seen a brand new pattern on bitcoin twitter recently, individuals altering their profile photos to some type of a Reuben sandwich. I’m going to elucidate what this implies, why it is best to care and why it is best to think about additionally turning into a Reuben sandwich. First I need to deal with one thing necessary, the Rubin’s Reubens photos will not be NFTs, they don’t seem to be inscriptions, they’re merely AI generated artwork that anybody can select to make use of at no cost.
The identify comes from Jeremy Rubin (@JeremyRubin), the creator of OP_CTV and BIP119, and the likeness between Rubin and Reuben. Which you will have already found out. 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 mix supplies a bit extra flexibility and programmability than simply OP_CTV alone, and allows further issues similar to LN symmetry/eltoo.
In a earlier article I defined that bitcoin has a scaling problem and that covenants, together with CTV, could be a resolution to assist with this. Nonetheless I did not focus on the method concerned with how we really activate these new OP codes. By design, it isn’t a fast or simple course of to delicate fork bitcoin with the intention to change the consensus guidelines. However what even is consensus? This can be a powerful query with a variety of nuance, and the reply will rely upon who you ask. Prior to now there was an idea of tough consensus, the place as soon as the change is properly mentioned and there are not any extra affordable issues left to dispel concerning a proposal, you will have reached tough consensus. Some individuals imagine consensus is discovered when companies, similar to pockets suppliers, exchanges and miners agree on a change. And even simply the miners alone, as if you happen to delicate forked and not using a majority of miner hash assist, you’d be rejecting the blocks from the heavier chain, then it is going to be as much as the market to determine which is the true bitcoin. This may be very messy and sophisticated, therefore it is a lot easier if you will get the miners on board with the improve. The truth 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 troublesome, if not unattainable. Nonetheless you should attempt to decide the extent of consensus for a proposal earlier than making an attempt to activate it.
In April 2022 Jeremy Rubin proposed a speedy trial activation of CTV, this didn’t go properly, and led to the fork being very contentious. Speedy trial is the place the ultimate resolution whether or not to activate a delicate fork proposal or not, is given to the miners. Simply 5 months earlier taproot was activated utilizing the identical speedy trial methodology. Nonetheless many individuals felt it didn’t go properly, they usually weren’t snug giving the miners the power to say no to a change which 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 instrument for customers to withstand a CTV activation try (Person Resisted Softfork) with the activation consumer. So now 2 years later the group is taking a look at one other activation try, however this time there will not be any speedy trial methodology.
So what are the choice methods to activate a delicate fork? There are 2 BIPs (Bitcoin Enchancment Proposals) which might 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 attaining the activation threshold, then the try fails and there’s no delicate fork. BIP8 makes use of block peak to guage time durations and may 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 known as “lockinontimeout” or lot for brief, when set to true the delicate fork will activate it doesn’t matter what. This pressured activation known as a UASF (Person Activated Mushy Fork), and may 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 observe the financial majority and never improve, however if you happen to do have the financial majority supporting the change, miners must observe them on account of financial incentives from the miners wishing to get essentially the most charges attainable. Ideally the miners will sign sufficient assist earlier than the tip of the signaling interval, and the drama of a UASF may be averted. It was the specter of UASF that induced the miners in 2017 to conform to the Segwit improve and never improve the blocksize just like the Bcashers wished. (Sure, technically the blocksize did nonetheless improve a bit.)
We now must briefly focus on activation parameters, these are the specifics of the activation, and consists of the next: the identify; the model bit quantity; the beginning block peak; the sign interval timeout block peak; the minimal activation block peak; the edge of blocks signaling; and at last whether or not lockinontimeout is true or false. The identify ought to typically simply be the BIP quantity, in CTVs case, BIP119. The model bit may be any that is not getting used already. The beginning is but to be decided, I’d hope it may be someday in 2024, nevertheless it is a group resolution in the end. The sign interval timeout must be a minimum of 1 12 months after the beginning, some really feel 2 or extra years can be even higher, once more it is a group resolution 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 peak is the earliest potential time that the delicate fork may activate, this could possibly be earlier than the tip of the sign interval, similtaneously the timeout or after the timeout. I imagine it must be a minimum of 6 months after the beginning peak. The brink is what number of blocks in a 2 week issue interval, 2016 blocks, are required to activate by way of 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 should be signaling assist for the improve in a 2 week interval. Lastly, as we already mentioned, lockinontimeout ought to in all probability be set to true in order for you the group to assist the activation try.
So how will we get to a degree of feeling assured we have now 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 manner to take action. Do not be afraid to ask questions on something you do not perceive or agree with, keep in mind, we confirm round right here not simply belief. Have interaction together with your favorite bitcoin companies, ask them their opinion of CTV and be sure you allow them to know yours, in any case, you’re the buyer. If you’re a developer, you would evaluate the code, or create a proof of idea for CTV. There may be presently over 5 BTC up for grabs if you happen to can create a constructive proof of idea, or a adverse 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 person discovering any points. You could find this bounty right here: https://bipbounty.org/bounties/1e101655-bad8-5147-82f7-f03145d567af/.
In fact, in a decentralized system like bitcoin, we are able to by no means know for certain that the financial majority want a change, we are able to solely take a tough guess and hope for one of the best. We cannot discover out till we strive although. I imagine we’re both extraordinarily shut or have already discovered consensus for CTV. Be sure you head to utxos.org/indicators and add your identify or enterprise to the record, you may sign sure or no. Additionally, you will discover tons extra details about covenants on this web site.
