Add IPNS Record code - Githubissues

lidel commented 1 year ago

This PR proposes adding ipns-record, like we already have one for libp2p-peer-record. https://github.com/ipfs/specs/issues/369

Rationale / potential uses:

Main one: we should add a dedicated codec for IPNS Record, otherwise people will use ipns(0xe5) code which would be invalid, as it indicates IPNS "namespace".
IPIP-351 will ship in Kubo 0.19 and will allow fetching signed (verifiable) IPNS Record.
- In the future /ipns/{id}?format=car could return a CAR with ipns-record as an additional block.
IPNI wants to support IPNS Records, but need codec (https://github.com/ipni/specs/pull/4)

Sorry for my ignorance on some of this, but is this intended to be used in CIDs, and is the block format the IPNS protobuf format?

@rvagg correct.

Block identified by CID with this codec can be parsed by following the protobuf from the IPNS spec: https://github.com/ipfs/specs/blob/main/ipns/IPNS.md#record-serialization-format

multiformats / multicodec
