My name's Lautaro and I'm currently acting as Tech Lead of Po.et. At Po.et we use colored coins to store data on the Bitcoin blockchain with prefix "POET".

I've read in an old version of the OP_RETURN entry of the bitcoin wiki that protocols wishing to claim OP_RETURN prefixes should use the standard Bitcoin Improvement Proposals process.

That entry seems to have changed recently, no longer stating that we should follow the BIP process, and I haven't been able to find any existing BIP claiming an OP_RETURN prexif, but for the sake of thoroughness I'd like to ask for your help or confirmation here.

Should we actually be using the BIP process to claim a prefix?

Thanks in advance,

Lautaro
