Peer DID

1 min read
Pronunciation
[peer dee-eye-dee]
Analogy
Like two people exchanging encrypted business cards directly rather than registering them in a public directory.
Definition
A Decentralized Identifier (DID) method enabling direct peer-to-peer DID exchanges without a global ledger, storing DID documents locally and exchanging via secure messaging.
Key Points Intro
Peer DIDs facilitate private, off‑ledger identity exchanges.
Key Points

Local storage: DID document kept by peers, not on-chain.

Out‑of‑band exchange: Shared via QR code or secure channel.

Lightweight: No ledger fees or consensus required.

Use cases: Temporary connections, private channels.

Example
Two users initiate a chat by scanning each other’s Peer DID QR codes, establishing an encrypted DIDComm channel.
Technical Deep Dive
Peer DID: `did:peer:1zQm...`. DID document exchanged via DIDComm `invitation` message. Both store document in local wallet and derive shared keys via X25519.
Security Warning
Lost local storage means lost identity; implement backup.
Caveat
Peer DIDs lack global discoverability; suitable for private interactions only.
