RFC: #209

This RFC outlines the process for moving from formatting peer IDs as base58 multihashes to formatting them as CIDs with a special libp2p-key multicodec (0x72).

This RFC does not change the in-memory and/or network representation of peer IDs, just the textual format.

This process has two stages that must be completed in order:

  • Stage 1: Parse CIDs as peer IDs.
  • Stage 2: Format peer IDs as CIDs by default.

Tracking status of all libp2p implementations:

feat: support encoding/decoding peer IDs as CIDs in text (#41)
ba9101b 
What:

1. Supports decoding CIDs (of libp2p keys) as peer IDs 
   (libp2p/specs#216)
2. Continues to encode peer IDs as base58 multihashes by default.
3. Adds functions for converting between peer IDs and CIDs.
4. Deprecates IDB58{Decode,Encode}, replacing them with {Decode,Encode}.

Why:

1. We _need_ to support multibase somehow, so we can put peer IDs in domains.
2. This makes peer IDs fully self describing. That is, the CID itself indicates that it's a hash of a libp2p public key.
3. It's much easier to upgrade wire protocols than text. This change punts
pids-as-cids on the wire down the road but that's something we can revisit if it ever becomes relevant. 

See libp2p/specs#111 for context.

Deviations from that issue:

* This _retains_ the current peer ID inlining of ed25519 keys. That turned out to be a nightmare, one I'd like to punt a bit more down the road.
* Likewise, this _punts_ the question of embedding the multi-hash algorithm in the public key.
