René Pickhardt wrote on Delving Bitcoin about his discussions and ideas around whether Ark’s best use case might be as a flexible channel factory rather than as an end-user payment solution... Craig Raw posted to the Bitcoin-Dev mailing list a proposal for a draft BIP, which defines a new top-level descriptor script expression sp() for silent payments...

Bitcoin Optech newsletter #386 is here: - summarizes a vault-like scheme using blinded MuSig2 - describes a proposal for Bitcoin clients to announce and negotiate support for new P2P features - links to 2106 timestamp overflow discussion and considerations around BIP54 - notes a CTV activation meeting and CTV footgun discussion - summarizes the OP_CHECKCONSOLIDATION proposal - links to a report of hash-based post-quantum signature schemes - Optech Newsletter #386 Podcast Jonathan T. Halseth posted to Delving Bitcoin a prototype of a vault-like scheme using blinded co-signers. Unlike traditional setups using co-signers, this scheme uses a blinded version of MuSig2 to ensure the signers know as little as possible about the funds they are involved in signing... Anthony Towns posted to the Bitcoin-Dev mailing list about a proposal for a new BIP to define a P2P message that would allow peers to announce and negotiate support for new features... Asher Haim posted to the Bitcoin-Dev mailing list asking Bitcoin developers to act promptly to prepare for a migration from uint32 to uint64 block timestamps... Josh Doman posted to the Bitcoin-Dev mailing list and Delving Bitcoin asking whether it’s might be worthwhile to modify the consensus cleanup proposal to be more permissive to odd block timestamp behavior to allow a potential soft fork solution to the 2106 block timestamp overflow issue... Chris Stewart posted to Delving Bitcoin a discussion of a “footgun” with OP_CHECKTEMPLATEVERIFY (CTV)... Developer 1440000bytes hosted a CTV (BIP119) activation meeting... billymcbip proposed an opcode specifically optimized for consolidations. OP_CHECKCONSOLIDATION (CC) would evaluate to 1 if and only if it’s executed on an input with the same scriptPubKey as an earlier input in the same transaction... Mikhail Kudinov and Jonas Nick posted to the Bitcoin-Dev mailing list about their work on evaluating hash-based signatures for use in Bitcoin...
