基于区块链的符合W3C DID和Verifiable Credential规范的分布式身份解决方案

Privacy-preserving identity and reputation infrastructure for .NET. DIDs, signed attestations, selective disclosure via Merkle bundles, Bulletproof predicate proofs, and multi-chain anchoring (Solana primary, Stellar secondary).

Typescript implementation of SD JWT VCDM

The EECC Verifier for Verifiable Credentials provides a verification API as well as the corresponding UI.

Rust implementation of Selective Disclosure for JWTs (SD-JWT)

Experimental implementation of sd-jwt for W3C Verifiable Credentials

Drop-in cryptographic audit trail for Cloudflare Project Think agents. Every lifecycle hook becomes a tamper-evident, hash-chained receipt anchored to a public ledger no operator controls. HIPAA / EU AI Act / SOC 2 / FedRAMP-grade audit trail at less than a thousandth of a cent per receipt.

SPICE SD-CWT

Portable W3C Verifiable Credentials for AI agents. Selective disclosure, holder binding, and Ed25519 signatures.

Cryptographic-proof data infrastructure for multi-party & AI-driven workflows: verifiable credentials (SD-JWT VC, OpenID4VCI/VP, HAIP), Merkle-chained distributed registers, HD wallets, post-quantum crypto (ML-DSA/ML-KEM), selective disclosure, and a 36-tool MCP server. .NET 10 / Aspire.
