New versions of the Multibase and Multihash specs have been published. Multibase is just a date bump to signal that the specification is still alive and being used. There are no new base-encoding mechanisms that have been added to this release. This community uses multibase to encode a number of values, like signature values and did:key values, in Verifiable Credentials and Decentralized Identitifer Documents: https://datatracker.ietf.org/doc/html/draft-multiformats-multibase-03 Multihash adds the KangarooTwelve hash function to the list of available hash functions. KangarooTwelve's strongest draw is that it's fun to say out loud... and is a KECCAK-based highly parallel hash function, if you're into that sort of thing. This community uses multihash in some DID Methods (Veres One uses it for hash values for operations and blocks), and the DID Core specification uses multihash for Hashlinks (to provide integrity protection for DID Documents): https://datatracker.ietf.org/doc/html/draft-multiformats-multihash-02 Fairly boring stuff, but nevertheless, foundational building blocks upon which many of us have built our implementations. -- manu -- Manu Sporny - https://www.linkedin.com/in/manusporny/ Founder/CEO - Digital Bazaar, Inc. blog: Veres One Decentralized Identifier Blockchain Launches https://tinyurl.com/veres-one-launches
