What is `DID`?

Definitions

• Decentralized Identifiers are persistent, long-term account identifiers.  They are a new type of identifier that enables verifiable, decentralized digital identity.

  DID is a W3C standard, with many standardized and proposed DID method implementations.

  Bluesky developed their own implementation, did:plc, the plc stands for Public Ledger of Credentials. 

• DIDs, or Decentralized IDentifiers, are universally-unique identifiers which represent data repos. They are permanent and non-human-readable. DIDs are a W3C specification. The AT Protocol currently supports did:web and did:plc, two different DID methods.

  DIDs resolve to documents which contain metadata about a repo, including the address of the repo's PDS, the repo's handles, and the public signing keys.
