## 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.
- [3ID](https://www.notion.so/3ID-Identity-System-fac2f47862a84602b366af1cd64f3523) - 3ID is a blockchain-agnostic DID system built by 3Box and Ceramic Network.
- [3ID/Ceramic](https://www.notion.so/3ID-Identity-System-fac2f47862a84602b366af1cd64f3523) - [3ID](https://docs.3box.io/faq/data-identi) is an identity system that links a user's Ethereum address to a DID. They are in the process of migrating to a blockchain-agnostic DID network called [Ceramic](https://github.com/ceramicnetwork/specs#index).
- [Sovrin](https://sovrin.org/) - Sovrin is a permissioned blockchain identity network that implements DIDs. Consensus in the Sovrin network is maintained by approved validator nodes.

- [ION](https://techcommunity.microsoft.com/t5/identity-standards-blog/ion-booting-up-the-network/ba-p/1441552) is a Microsoft-led DID system. It is an implementation of [Sidetree](https://github.com/decentralized-identity/sidetree), a blockchain-agnostic DPKI protocol, that runs on Bitcoin. It stores transaction data in IPFS.
- IBM - IBM is helping to create, operate and maintain [permissioned decentralized identity networks](https://www.ibm.com/blockchain/solutions/identity/networks) that implement DIDs, built using Hyperledger, IBM's permissioned ledger.
