You will have seen a brand new pattern on bitcoin twitter currently, folks 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 turning into a Reuben sandwich. First I need to deal with one thing essential, the Rubin’s Reubens photographs are usually not 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 help 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 further issues akin to LN symmetry/eltoo.
In a earlier article I defined that bitcoin has a scaling situation and that covenants, together with CTV, generally is a answer 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 isn’t a fast or simple course of to comfortable fork bitcoin with a purpose 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 depend upon who you ask. Prior to now there was an idea of tough consensus, the place as soon as the change is nicely mentioned and there aren’t any extra cheap issues left to dispel relating to a proposal, you have got reached tough consensus. Some folks imagine consensus is discovered when companies, akin to pockets suppliers, exchanges and miners agree on a change. And even simply the miners alone, as in case you comfortable forked and not using a majority of miner hash help, 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 less complicated if you may 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 tough, if not not possible. Nonetheless you need to 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 nicely, 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 technique. Nonetheless many individuals felt it didn’t go nicely, and so they weren’t comfy giving the miners the flexibility 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 device for customers to withstand a CTV activation try (Person 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 comfortable 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 intervals. 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 peak to evaluate time intervals 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 known as “lockinontimeout” or lot for brief, when set to true the comfortable fork will activate it doesn’t matter what. This compelled activation is known as a UASF (Person Activated Delicate Fork), and might solely succeed long run if nearly all 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 in case you do have the financial majority supporting the change, miners must observe them attributable to financial incentives from the miners wishing to get probably the most charges attainable. Ideally the miners will sign sufficient help earlier than the tip of the signaling interval, and the drama of a UASF may be prevented. It was the specter of UASF that brought on the miners in 2017 to conform to the Segwit improve and never enhance the blocksize just like the Bcashers wished. (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 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 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 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 this can be a neighborhood choice finally. The sign interval timeout must be not less than 1 12 months after the beginning, some really feel 2 or extra years can be even higher, once more this can be a neighborhood choice and the consumer developer should try to choose 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 comfortable fork may activate, this might be earlier than the tip of the sign interval, concurrently the timeout or after the timeout. I imagine it must be not less than 6 months after the beginning peak. The edge is what number of blocks in a 2 week issue 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 should be signaling help 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 help the activation try.
So how will 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 help 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, bear in mind, we confirm round right here not simply belief. Interact together 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. If you’re a developer, you could possibly evaluate the code, or create a proof of idea for CTV. There’s at the moment over 5 BTC up for grabs in case you can create a optimistic proof of idea, or a destructive 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 will discover 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 positive that the financial majority need a change, we are able to solely take a tough guess and hope for the most effective. 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/alerts and add your identify or enterprise to the listing, you’ll be able to sign sure or no. Additionally, you will discover tons extra details about covenants on this web site.
