To date, every known blockchain uses 256-bit signature keys. Most use truncated hashes of the public key, and all use either hexadecimal or some other ASCII encoding for the wallet address. I have not seen any suggestion that future blockchains would use post-quantum signatures. Thus, 255 characters is more than sufficient for all known and currently-expected wallet addresses. > Maybe we safely leave this up to the application because the first field > should identify the type anyway ... Just thinking aloud. Exactly. And, if someone comes up with a wallet that needs more than 255 characters, they can define a WALLET2 RRTYPE for those addresses. I find this exceedingly unlikely to happen because space is extremely expensive on blockchains, and every transaction has two wallet addresses. And the interest in blockchains may have subsided before there is any chance of needing post-quantum signatures. --Paul Hoffman _______________________________________________ DNSOP mailing list -- dnsop@ietf.org To unsubscribe send an email to dnsop-le...@ietf.org
