You will have observed a brand new pattern on bitcoin twitter recently, folks altering their profile footage to some type of a Reuben sandwich. I’m going to elucidate what this implies, why you must care and why you must contemplate additionally turning into a Reuben sandwich. First I need to deal with one thing vital, the Rubin’s Reubens photos aren’t NFTs, they don’t seem to be inscriptions, they’re merely AI generated artwork that anybody can select to make use of without cost.
The identify comes from Jeremy Rubin (@JeremyRubin), the creator of OP_CTV and BIP119, and the likeness between Rubin and Reuben. Which you’ll have already found out. So by having a Reuben sandwich as your profile image or by displaying the 🥪 emoji you might be signaling your help for the CTV or extra not too long ago 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 additional issues equivalent to LN symmetry/eltoo.
In a earlier article I defined that bitcoin has a scaling subject and that covenants, together with CTV, is usually 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’s not a fast or simple course of to comfortable fork bitcoin in an effort to change the consensus guidelines. However what even is consensus? This can be a robust query with quite a 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 nicely mentioned and there aren’t any extra cheap issues left to dispel relating to a proposal, you will have reached tough consensus. Some folks imagine consensus is discovered when companies, equivalent to pockets suppliers, exchanges and miners agree on a change. And even simply the miners alone, as in case you comfortable forked with out a majority of miner hash help, 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 sophisticated, 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 troublesome, if not inconceivable. Nonetheless you should 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 nicely, and led to the fork being very contentious. Speedy trial is the place the ultimate resolution 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 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 price noting that Jeremy additionally launched a device for customers to withstand a CTV activation try (Person Resisted Softfork) with the activation shopper. So now 2 years later the group 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 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 intervals. If the signaling interval ends with out attaining the activation threshold, then the try fails and there’s no comfortable fork. BIP8 makes use of block top to guage 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 edge. 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 pressured activation is known as a UASF (Person 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 in case you do have the financial majority supporting the change, miners must observe them as a consequence of 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 averted. It was the specter of UASF that triggered the miners in 2017 to comply with the Segwit improve and never improve the blocksize just like the Bcashers needed. (Sure, technically the blocksize did nonetheless improve a bit.)
We now have to 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 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, nonetheless it is a group resolution finally. The sign interval timeout needs to be a minimum of 1 12 months after the beginning, some really feel 2 or extra years could be even higher, once more it is a group resolution and the shopper developer should attempt to decide what the bulk agree with, I might 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, similtaneously the timeout or after the timeout. I imagine it needs to be a minimum of 6 months after the beginning top. The edge is what number of blocks in a 2 week issue interval, 2016 blocks, are required to activate by means 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 have to 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 need the group to help the activation try.
So how will we get to some extent of feeling assured we now have discovered consensus? Participating with the group, having conversations with bitcoin companies and repair suppliers, and signaling help on-line in varied 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. Interact along with your favorite bitcoin companies, ask them their opinion of CTV and make sure to allow them to know yours, in spite of everything, you’re the buyer. If you’re a developer, you would evaluate the code, or create a proof of idea for CTV. There’s at present over 5 BTC up for grabs in case you can create a constructive proof of idea, or a detrimental 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/.
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 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/alerts and add your identify or enterprise to the checklist, you’ll be able to sign sure or no. Additionally, you will discover tons extra details about covenants on this web site.
