About the show

The Rubric helps you understand the technologies behind Decentralized Identity, including Decentralized Identifiers, also known as DIDs (or D.I.D.s), DID documents and DID methods. We review different DID methods using a common set of criteria, comparing apples to apples, so you can make better decisions about which DID method is appropriate for your needs.

Faster, Cheaper, and More Private: the Sequel IS Better! (did:btcr2, Part 2)

did:btcr2 is a censorship-resistant DID method using the Bitcoin blockchain as a Verifiable Data Registry to announce changes to the DID document. It improves on prior work by allowing: zero-cost off-chain DID creation; aggregated updates for scalable on-chain update costs; long-term identifiers that can support frequent updates; private communication of the DID document; private DID...

Didja JWK? We did! (did:jwk, Part 2)

did:jwk embeds a JSON Web Key (JWK) in a DID to enable the use of JWKs in DID-enabled systems. Simple and straightforward, it promises to give did:key and did:pkh a run for their money. We talk with two of the co-authors of did:jwk, Jeremie Miller, known for creating Jabber and XMPP, and Orie Steele, CTO...
