# What is IDA

**Decentralized Identity Platform for People, Organizations, and AI Agents**

***

## Vision

Restore the original promise of the internet as a decentralized, open, and trust-enabled network by giving users -- and AI agents -- full sovereignty over their digital identities, credentials, and personal data.

## What is IDA?

IDA is a Decentralized Identity (DID) platform built on the **ADI blockchain** that enables individuals, organizations, and AI agents to own, control, and manage their digital identities without reliance on centralized identity providers.

The platform implements:

* **W3C Decentralized Identifiers (DIDs)** -- self-sovereign, cryptographically verifiable identifiers
* **Verifiable Credentials (VCs)** -- tamper-evident digital credentials with selective disclosure
* **Digital Wallets & Agents** -- end-user software for credential management and agent-to-agent communication
* **AI Agent Identity** -- first-class DID identity for autonomous AI agents with delegation chains, capability tokens, and trust scoring

## Key Features

| Feature                      | Description                                                                      |
| ---------------------------- | -------------------------------------------------------------------------------- |
| **Self-Sovereign Identity**  | Users own and control their DIDs and credentials -- no central authority         |
| **W3C Standards Compliant**  | Full DID Core v1.0 and VC Data Model v2.0 compliance                             |
| **Privacy by Design**        | Selective disclosure via BBS+ signatures, zero-knowledge proofs                  |
| **AI Agent DIDs**            | Autonomous agents get their own `did:adi:agent:*` identifiers                    |
| **Delegation Chains**        | Cryptographically verifiable human-to-agent authorization with scope attenuation |
| **Capability Tokens (IBCT)** | Invocation-Bound Capability Tokens fusing identity + authorization + provenance  |
| **Agent Trust Registry**     | On-chain reputation scoring and capability attestation for AI agents             |
| **MCP-I & A2A Support**      | Interoperable with Model Context Protocol and Google Agent-to-Agent protocol     |
| **ADI Blockchain**           | Native blockchain with \<5s finalitylt;5s finality and 1000+ TPS                 |

## Trust Model

IDA implements a Web of Trust connecting five primary roles:

| Role         | Description                                                                   |
| ------------ | ----------------------------------------------------------------------------- |
| **Subject**  | Entity about which verifiable claims are made                                 |
| **Holder**   | Entity holding VCs in a wallet, generating presentations                      |
| **Issuer**   | Trusted entity asserting claims and issuing VCs                               |
| **Verifier** | Relying party that cryptographically verifies presentations                   |
| **AI Agent** | Autonomous software entity with its own DID, acting under delegated authority |
