You’ll have observed a brand new development on bitcoin twitter these days, individuals altering their profile footage 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 changing into a Reuben sandwich. First I have to handle one thing necessary, the Rubin’s Reubens pictures usually are not NFTs, they aren’t 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 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 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 corresponding to LN symmetry/eltoo.
In a previous article I defined that bitcoin has a scaling situation 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 really activate these new OP codes. By design, it isn’t a fast or simple course of to tender fork bitcoin with the intention to change the consensus guidelines. However what even is consensus? This can be a robust query with loads of nuance, and the reply will rely upon who you ask. Previously there was an idea of tough consensus, the place as soon as the change is properly mentioned and there are not any extra affordable considerations left to dispel relating to a proposal, you’ve reached tough consensus. Some individuals imagine consensus is discovered when companies, corresponding to pockets suppliers, exchanges and miners agree on a change. And even simply the miners alone, as in the event you tender forked with out 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 resolve which is the true 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 an element. Measuring that is extremely tough, if not unattainable. Nevertheless you should attempt to choose 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 determination whether or not to activate a tender fork proposal or not, is given to the miners. Simply 5 months earlier taproot was activated utilizing the identical speedy trial technique. Nevertheless many individuals felt it didn’t go properly, and so they 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 shopper 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 shopper. So now 2 years later the neighborhood is one other activation try, however this time there will not be any speedy trial technique.
So what are the choice methods to activate a tender 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 intervals. If the signaling interval ends with out reaching the activation threshold, then the try fails and there’s no tender fork. BIP8 makes use of block top to evaluate time intervals and might be configured to both fail after a sign interval with out sufficient miner signaling, similar 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 tender fork will activate it doesn’t matter what. This pressured activation known as a UASF (Person 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 in the event you do have the financial majority supporting the change, miners must comply with them as a consequence of financial incentives from the miners wishing to get probably the most charges doable. Ideally the miners will sign sufficient assist earlier than the tip of the signaling interval, and the drama of a UASF might be prevented. It was the specter of UASF that brought about the miners in 2017 to conform to the Segwit improve and never enhance the blocksize just like the Bcashers needed. (Sure, technically the blocksize did nonetheless enhance a bit.)
We now must briefly focus on activation parameters, these are the specifics of the activation, and contains the next: the identify; 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 at last 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 might be any that is not getting used already. The beginning is but to be decided, I might hope it may be someday in 2024, nonetheless it is a neighborhood determination finally. The sign interval timeout needs to be at the least 1 12 months after the beginning, some really feel 2 or extra years could be even higher, once more it is a neighborhood determination and the shopper developer should try to choose what the bulk agree with, I might be proud of 1 to 2 years of signaling interval. The minimal activation top is the earliest potential time that the tender 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 needs to be at the least 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. Typically 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 neighborhood to assist the activation try.
So how can we get to some extent of feeling assured we have now discovered consensus? Partaking 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 means 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 you’ll want to allow them to know yours, in spite of everything, you’re the buyer. In case you are a developer, you can assessment the code, or create a proof of idea for CTV. There may be at present over 5 BTC up for grabs in the event 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 12 months already, with no one discovering any points. You’ll find this bounty right here: https://bipbounty.org/bounties/1e101655-bad8-5147-82f7-f03145d567af/.
In fact, in a decentralized system like bitcoin, we will by no means know for certain that the financial majority need a change, we will solely take a tough guess and hope for the most effective. We can’t 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/signals and add your identify or enterprise to the listing, you possibly can sign sure or no. Additionally, you will discover heaps extra details about covenants on this web site.
