A BitName can have various data associated with it on-chain;
- IP/port addresses
- Encryption pubkeys
- Verification keys, for checking message signatures
- A 32-byte commitment to arbitrary data
The IP/port addresses and the 32-byte commitment can be used together to commit to more data than is stored on chain.
The IP/port addresses can host a JSON-RPC server with a method /bitname_commit, which accepts an optional hex-encoded byte array as an argument.
IPv4 socket addresses are resolved with priority.
bitname_commit SHOULD, when the byte array argument is omitted,
return a JSON object that is canonical, in accordance with RFC-8785.
This object will be hashed using BLAKE3, and the digest compared to
the 32-byte on-chain commitment.
If these match, then any data contained in the JSON object can be considered
to be associated to the BitName.
This protocol is optionally recursive; The JSON object could commit to other commitments, and socket addresses that host a compatible RPC server. The first RPC call to the server hosted at an IP/port address does not use the bytes argument, but subsequent calls MAY. How recursive commitments are resolved is an implementation choice for the resolver.
