https://github.com/bitcoin/bips/pull/2118 Finally, the PR to assign BIP numbers to the first two BIPs of the "script restoration quartet". Here's the corresponding bitcoin-dev the mailing list post: Hi all, I've submitted a PR to the BIPs repo to merge the first two drafts of the previously posted[1] "A Bitcoin Scripting Proposal BIP Quartet": https://github.com/bitcoin/bips/pull/2118 The only substantive change since the last discussion is that the costs have increased for some operations (hashing and copying bytes), as a result of benchmarking on a wider array of machines[2]. This follows our conservative approach to make the worst-case validation times no worse than they are presently, on any viable hardware. The remaining two BIPs (OP_TX, and new opcodes) are not submitted: they are mainly useful to provide a roadmap what functional gaps remain after the script extensions, and do not have full implementations. Cheers! Rusty & Julian. [1] https://groups.google.com/g/bitcoindev/c/GisTcPb8Jco/m/8z… [2] https://github.com/jmoik/varopsData
