Hey folks, based on some discussions in the DID community, and some crossover discussion with the Social Web community, we've identified a potential specification for cryptographic event logs. Think of these like "local blockchains", but without the network, consensus protocols, or cryptocurrencies (all the controversial bits). It's just a pure list of changes to a piece of data that's been digitally signed when the data changed. This work matters because we believe that we can create a truly decentralized DID Method, that does not require a blockchain, with this core primitive. The same core primitive could be used for fully decentralized social web media posts. We've been collaborating with Christine (of ActivityPub, OCaps, and ZCAPs fame) and the Spritely Institute[1], the good folks working on did:webvh[2], we've taken the BlueSky requirements[3] into account, and (of course), not much of this is new -- these concepts have been in floating around for 40+ years, and more recently blockchains, did:peer, did:webvh, Gordian Envelopes, and a variety of other cryptographic data structures that record change events to a file. We're announcing the CEL spec today, which is a cryptographic protocol for verifying a log of changes to data: https://digitalbazaar.github.io/cel-spec/ We'll probably request adoption as a W3C CCG work item after the holiday break. In the meantime, please take a look, provide any concerns/issues as feedback to the mailing list, or ideally, an issue on the github repo: https://github.com/digitalbazaar/cel-spec/ With all that said, happy to answer any questions, concerns, or explore possibilities with folks on this mailing list. :) -- manu [1]https://spritely.institute/ [2]https://github.com/digitalbazaar/cel-spec/issues/3 [3]https://lists.w3.org/Archives/Public/public-credentials/2024Dec/0043.html -- Manu Sporny - https://www.linkedin.com/in/manusporny/ Founder/CEO - Digital Bazaar, Inc. https://www.digitalbazaar.com/
