What is IDA | IDA — Identity for the AI Age

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

Architecture at a Glance

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
