You might have seen a brand new development on bitcoin twitter recently, individuals altering their profile footage to some type of a Reuben sandwich. I’m going to elucidate what this implies, why it’s best to care and why it’s best to take into account additionally changing into a Reuben sandwich. First I need to deal with one thing necessary, the Rubin’s Reubens pictures will not be NFTs, they aren’t inscriptions, they’re merely AI generated artwork that anybody can select to make use of without spending a dime.
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 discovered. So by having a Reuben sandwich as your profile image or by displaying the 🥪 emoji you might be signaling your assist for the CTV or extra just 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 offers a bit extra flexibility and programmability than simply OP_CTV alone, and permits additional issues similar to LN symmetry/eltoo.
In a earlier article I defined that bitcoin has a scaling concern and that covenants, together with CTV, is usually a resolution to assist with this. Nonetheless I did not focus on the method concerned with how we truly activate these new OP codes. By design, it’s not a fast or straightforward course of to delicate fork bitcoin to be able to change the consensus guidelines. However what even is consensus? This can be a powerful query with a whole lot 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 cheap considerations left to dispel relating to a proposal, you may 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 when you delicate 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 true bitcoin. This may be very messy and complex, 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 an element. Measuring that is extremely troublesome, if not inconceivable. Nonetheless 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 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 technique. Nonetheless many individuals felt it didn’t go effectively, they usually weren’t comfy 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 software for customers to withstand a CTV activation try (Consumer Resisted Softfork) with the activation consumer. So now 2 years later the neighborhood is taking a look at one other activation try, however this time there will not be any speedy trial technique.
So what are the choice methods to activate a delicate 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 delicate fork. BIP8 makes use of block peak to evaluate 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 brink. This parameter is named “lockinontimeout” or lot for brief, when set to true the delicate fork will activate it doesn’t matter what. This pressured activation is named a UASF (Consumer Activated Delicate 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 when you do have the financial majority supporting the change, miners must observe them resulting from financial incentives from the miners wishing to get probably 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 prevented. It was the specter of UASF that precipitated the miners in 2017 to comply with the Segwit improve and never enhance the blocksize just like the Bcashers needed. (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 identify; the model bit quantity; the beginning block peak; the sign interval timeout block peak; the minimal activation block peak; the brink of blocks signaling; and eventually whether or not lockinontimeout is true or false. The identify ought to usually 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 might hope it may be someday in 2024, nevertheless it is a neighborhood resolution finally. The sign interval timeout needs to be not less than 1 yr after the beginning, some really feel 2 or extra years can be even higher, once more it is a neighborhood resolution and the consumer developer should try to decide what the bulk agree with, I might 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 may very well be earlier than the tip of the sign interval, similtaneously the timeout or after the timeout. I imagine it needs to be not less than 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 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 in all probability be set to true if you’d like the neighborhood to assist the activation try.
So how can we get to a degree of feeling assured now we have discovered consensus? Participating with the neighborhood, 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 method 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. Interact along 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 possibly can evaluate the code, or create a proof of idea for CTV. There may be at present over 5 BTC up for grabs when you can create a optimistic 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 yr already, with no person 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 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 can’t discover out till we strive although. I imagine we’re both extraordinarily shut or have already discovered consensus for CTV. Be sure to head to utxos.org/indicators and add your identify or enterprise to the listing, you’ll be able to sign sure or no. Additionally, you will discover heaps extra details about covenants on this web site.
