Trusted Web

The Trusted Web Promotion Council is a Japanese government-led initiative launched in 2020 that aims to develop a technology-neutral trust framework for digital society. The project focuses on expanding verifiable data exchange without over-reliance on specific services through six core technical components: Verifiable Data, Identity, Node, Message, Transaction, and Transport. This architecture is designed to enable users and organizations to maintain control over their data while incorporating mechanisms for consensus building and traceability.

The technical implementation leverages existing standards and technologies while developing new complementary solutions. Key features include:

• Support for Verifiable Credentials and identity graphs
• Distributed storage with confidential sharing capabilities
• Technology-neutral approach allowing various implementation methods
• Integration with existing legal frameworks and business customs

Notable implementations include:

Healthcare data sharing between doctors and researchers
Supply chain chemical management platforms
Cross-border personal information management
Digital certification platforms for business identities

The initiative maintains an open development approach through its GitHub repository and regularly publishes technical white papers that detail architectural updates and implementation guidelines. While primarily Japanese government-backed, the Trusted Web Promotion Council actively seeks international collaboration and input from various stakeholders to ensure the framework remains globally applicable and interoperable.
