FWIU, Cyph does Open Source E2E chat, files, and unlimited length social posts to circles or to public; but doesn't yet do encrypted git repos that can be solved with something like git-crypt.

It would be wasteful to throw away the Web of Trust (people with handles to keys) that everyone entered into Keybase. Hopefully, Zoom will consider opening up the remaining pieces of Keybase if not just spinning the product back out to a separate entity?

> There's also "Web Key Directory"; which hosts GPG keys over HTTPS from a .well-known URL for a given user@domain identifier: https://wiki.gnupg.org/WKD

> GPG presumes secure key distribution

> Compared to existing PGP/GPG keyservers [HKP], WKD does rely upon HTTPS.

Blockcerts can be signed when granted to a particular identity entity:

CT Certificate Transparency logs for key grants and revocations may depend upon a centralized or a decentralized Merkleized datastore:

How do I specify the correct attributes of my schema.org/Person record (maybe on my JAMstack site) in order to approximate the list of identities that e.g. Keybase lets one register and refer to a cryptographic proof of?

Do I generate a W3C DID and claim my identities by listing them in a JSON-LD document signed with W3C ld-proofs (ld-signatures)? Which of the key directory and Web of Trust features of Keybase are covered by existing W3C spec Use Cases?

>> 2. Use Cases: Online shopper, Vehicle assemblies, Confidential Customer Engagement, Accessing Master Data of Entities, Transferable Skills Credentials, Cross-platform User-driven Sharing, Pseudonymous Work, Pseudonymity within a supply chain, Digital Permanent Resident Card, Importing retro toys, Public authority identity credentials (eIDAS), Correlation-controlled Services

> And then, IIUC W3C Verifiable Credentials / ld-proofs can be signed with W3C DID keys - that can also be generated or registered centrally, like hosted wallets or custody services. There are many Use Cases for Verifiable Credentials: https://www.w3.org/TR/vc-use-cases/ :

Is there an ACME-like thing to verify online identity control like Keybase still does?
