Affinidi Trust Network

The Affinidi Trust Network is a digital identity infrastructure developed by Temasek Holdings that enables privacy-preserving data exchange and identity management. Launched in 2020, it implements Self-Sovereign Identity principles through a suite of products built on W3C DID and Verifiable Credentials standards.

The network's core components include:

• Affinidi Vault - A digital wallet for storing and managing credentials
• Affinidi Login - A passwordless authentication system using OID4VP protocol
• Affinidi Elements - Developer tools and APIs for credential issuance and verification
• Affinidi Connectors - Integration tools for various data sources
• Affinidi Messaging - Secure communication between network participants

The technical implementation leverages several key standards and protocols:

• W3C Verifiable Credentials Data Model for credential format
• did:key method for decentralized identifiers
• OpenID Connect extensions for verifiable presentations
• Encrypted Data Vaults for secure credential storage

Notable adoption includes partnerships with:

Etihad Airways for digital health credentials
Singapore Airlines for COVID-19 test verification
Integration with Singapore's national digital identity infrastructure

The project maintains an open-source approach, having released its core SDK and developer toolkit in October 2020. While offering Self-Sovereign Identity capabilities, the system uses a hybrid model where some components like the vault service remain under centralized control of Affinidi.
