# Identity

Unique agent context (The Who)

Layer: Infrastructure · Category: Data Structures

## Mechanism

The unique distinguishing context of an agent, including its history, reputation, and public keys. Distinguishes 'Self' from 'Other'. Unlike [Nature](https://mindscape.world/scapes/bootstrap/Nature.md) (what you are) or Role (what you do), Identity is the persistent handle that tracks an entity across interactions.

## Data schema

```json
{
  "type": "object",
  "required": [
    "identifier"
  ],
  "properties": {
    "identifier": {
      "type": "string",
      "description": "The persistent handle that distinguishes this party from another within a scope. Key material, DID, UUID, account name or pseudonym are all admissible carriers — BearerToken and Role both reference an Identity without key material, so the carrier is a descendant concern."
    },
    "public_key": {
      "type": "string",
      "description": "Cryptographic identifier (DID/Key)"
    },
    "claims": {

    },
    "history_hash": {
      "type": "string",
      "description": "Pointer to interaction log"
