This objection seems straightforward to resolve: BIP 3 requires a 4 week period before moving a BIP to "closed", and if there is fewer than one block found per 4 week period, you can expect it will take about 150 years for the difficulty retarget point to be reached. So I'd suggest don't mark the BIP closed until there's been 18-28 days (100-150 years to the retarget) since the last BIP110 compliant block was found.

It got just shy of 2.5% of blocks signaling readiness in the latest signaling period, and since RDTS nodes mandated signaling, RDTS nodes relegated themselves to a chain that only found two blocks, while the Bitcoin blockchain grew by 134 blocks. The sole block author on the RDTS chaintip has since announced that they have ceased mining on the stalled chaintip. While it’s your choice to remain on the stalled chaintip or to throw-in with the hard fork that is now being discussed, it’s clear that the Bitcoin network rejected the soft fork. The minority hashrate chaintip therefore constitutes a forkcoin. Altcoins are not on-topic for the BIPs repository, and therefore, BIP110 should be advanced from Deployed to Closed as it is obsolete.

The only way to achieve that would a new BIP enforcing a confiscatory soft fork on top of the BIP 110 forked chain. Or a checkpoint on the winning chain. Nobody is advocating for either. Closing a BIP also doesn't ban anyone from running a node or continuing to mine. But the odds of catching up are slim. I'm not in a rush to close it, but what would be your own criteria for when it's reasonable to do so? I could spin up a BIP 12 (OP_EVAL) node tomorrow, reject P2SH by forking off at its activation height, and probably mine a whole bunch of blocks trivially. Modern Bitcoin Core wouldn't reject those blocks, because checkpoints have been removed. But I would never catch up with the tip. Nobody would seriously considering reopening BIP12 in such a scenario, even if I ran a million nodes. For BIP110, it was obvious to me years ago [1] that this was never going to work, not as a policy rule, and not as a consensus rule. For others it look longer realize this, and some people never will. Hard to put an exact number on when to close it, though now would be fine. - Sjors [0] https://github.com/bitcoin/bips/blob/master/bip-0012.mediawiki [1] see e.g. https://bitcoinexplainedpodcast.com/@nado/episodes/episode-98-return-of-the-op-return and my comments on On Sun, Aug 9, 2026, at 22:12, Greg Tonoski wrote: > The BIP-110 was activated at the block height as you (Mark Erhardt) approved in the specification.

Well, in the past, there was an altcoin, which supported OP_EVAL: it was called CoiledCoin. Back then, Luke had its own mining pool, and used that power, to basically make their chain unusable, by mining empty blocks, only with the coinbase transactions, which raised their difficulty to insane levels, where the community could no longer mine it, when he stopped. And then, he wrote: https://bitcointalk.org/index.php?topic=56675.msg676981#msg676981 > CoiledCoin now closed. Have a nice day. Now, people can simply say, that after all of these years, he simply got, what he deserved: "LukeCoin now closed. Have a nice day." Of course, any user can use any coin: CoiledCoin, BIP-110 coin, non-BIP-110 coin, or whatever. But if some chain is dead, and nobody pushes it forward, then I guess BIP can be closed: if someone wants to use a closed BIP, then it is just a choice of a given user. > Closing a BIP does not confiscate coins. I guess some people think, that if a BIP is there, then it is somehow supported, or accepted by the community. Which is simply not the case, because we have BIPs for block size increases, which are used only by some altcoins. Probably it is a similar case, as it is with testnets being traded: some people believe, that if a given testnet is included into Bitcoin Core, then it is more valuable, just because it is included. Which is also why people are patiently waiting for testnet5 to be included, to trade it instantly, even though anyone could simply launch a similar test network, and use it. Basically, including or excluding things into BIPs, or Bitcoin Core became more political, than it should be. Users can use whatever they want, but now, some people simply consider Bitcoin Core as a "brand", and a mere inclusion of something to be worthy. pon., 10 sie 2026 o 13:27 Sjors Provoost <sjors@sprovoost.nl> napisał(a): > Hi Greg, > > Closing a BIP does not confiscate coins.
