The Rubric

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)
10/10/2025
1:03:47
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...

23/07/2025
40:34
did:webvh adds historical verifiability to did:web, using cryptographic provenance to establish that the current DID document is the result of legitimate updates by the DID controller. Today on the show we talk with Stephen Curran and John Jordan, co-creators and implementers of the did:webvh specification.

Didja JWK? We did! (did:jwk, Part 2)
14/07/2025
48:30
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...
