Hi everyone,

We've recently made a number of updates to the OP_CAT BIP proposal
including adding a rationale section, an expanded backwards compatibility
section and an updated reference implementation.

It can be found as a PR to the bitcoin/bips repo here:
https://github.com/bitcoin/bips/pull/1525
or as BINANA BIN-2024-0001:
https://github.com/bitcoin-inquisition/binana/blob/master/2024/BIN-2024-0001.md

Thanks,
Ethan

Hi Ethan,

Very good to see your OP_CAT design is now on the mailing list.

Inside the BIP text, you mention that a sufficiently large OP_CAT script 
can "support tree signatures with a thousand public keys." I think it would 
be more useful to put the theoretical limit there, as it is buried along 
with the rest of the data on tree signatures inside the reference link to 
Blockstream's web page, which could go stale for whatever reason.

On a further note, if there are enough practical uses for tree signatures, 
we could make it into a fully fledged BIP too, instead of just something 
cool that would make the Stacker News front page.

- Ali

A number of people have privately sent me questions about the status
of the BIP number for OP_CAT. I want to publicly clarify two points in
regards to the OP_CAT BIP:
i. The OP_CAT BIP authors, Armin and I, have formally requested a BIP number,
ii. and no BIP number has yet been assigned (despite what is being
said on twitter).

Excellent point, I've updated the BIP to specify the theoretical
maximum of public keys. See commit
https://github.com/EthanHeilman/bips/commit/852502b9cf0568dc4c75d93aaaaee3d102002ec7

I'd love to see a tree signature BIP. You should make one.
