## Decentralized Identifiers (DIDs)

The format of a DID is: a scheme identifier, followed by the DID method, followed by a method-specific identifier. A simple example: `did:example:123456789abcdefghi`
DIDs point to DID documents. Entities holding DIDs may be authenticated via proofs, or verifiable credentials.
As of 2020, a [Peer DID Method Specification](https://openssi.github.io/peer-did-method-spec/) is under development, which does not require any central source of truth, and is suitable for private relationships.
#### DID Implementations

There are DID implementations, but few applications, as it is still new and untested. The current biggest user of DIDs are applications using [3Box](https://3box.io/), as 3Box creates a DID for the user that is associated with their Ethereum address.

They are in the process of migrating to a blockchain-agnostic DID network called [Ceramic](https://github.com/ceramicnetwork/specs#index).
