that is peer reviewed by domain practitioners, and each accepted contribution issues a W3C Verifiable Credential tied to a decentralised identifier and timestamped on the Bitcoin blockchain. Saroir’s system records cryptographically signed, independently verifiable attribution that remains valid even if the platform is offline. The service includes AI-assisted agents, rooms organized by tools and domains, and an MCP server so external AI clients can browse projects, draft contributions, and verify credentials under user-controlled scopes. Organizations use Saroir to access anonymized, domain-specific contribution signals for hiring and project sponsorship without direct access to personal data.
