Digital Address Protocol

The Digital Address Protocol is a specialized identity protocol developed by the Accountable Digital Identity Association (ADIA) for creating and managing unique digital identifiers within a trusted ecosystem. This protocol enables secure user onboarding and identity verification through certified Digital Address Issuers.

The protocol facilitates the creation of Digital Addresses - special ADIA identifiers issued to individuals after completing Know Your Customer (KYC) processes. It operates through a network of trusted agents and directories to maintain identity integrity and privacy.

Key features include:

• Unique identifier creation for users and entities
• Trust anchor verification through the ADIA Global Directory
• Agent-based architecture with multiple specialized roles
• Privacy-preserving directories that maintain hashed attributes
• Standardized message formats using JSON payloads

Purpose and Scope:

• Creates and manages unique digital identifiers within the ADIA ecosystem
• Enables secure user onboarding and identity verification
• Facilitates communication between different system agents
• Maintains identity integrity through trust anchors

Technical Specifications:

• Uses DIDComm-based messaging protocols
• Implements JSON message formats with standardized attributes
• Supports multiple protocol commands:
  • create-digital-address
  • verify-user
  • revoke-digital-address
  • resolve-digital-address
  • provision-agent

Implementation Requirements:

• Must be implemented by:
  • ARD Agent
  • DAS Agent
  • Issuer Agent
  • SP Agent
  • Cloud Agent

Security Considerations:

• Requires certified Digital Address Issuers
• Implements trust anchor verification
• Uses hashed attributes for privacy preservation
• Maintains secure agent-to-agent communications

Interoperability Features:

• Supports integration with existing Aries protocols
• Uses standardized message formats
• Implements common directory protocols
• Enables cross-entity communication

The protocol is actively maintained by the ADIA and continues to evolve with new security and functionality requirements.
