TypeScript port of deterministic CBOR (dCBOR), Gordian Envelope for privacy-preserving data, Uniform Resources (UR), secret sharing (SSKR/Shamir), XID decentralized identities, provenance marks, LifeHash visual hashing, and FROST threshold signatures.

A CBOR codec for TypeScript that focuses on writing and parsing deterministic CBOR ("dCBOR") per IETF. It deliberately does not support the parts of the CBOR spec that are forbidden by deterministic encoding (such as indefinite-length arrays and maps), and it is strict in both what it writes and what it reads.

Blockchain Commons Deterministic CBOR ("dCBOR") for TypeScript

Cross-language conformance suite for canonical CBOR (RFC 8949) and dCBOR — a fuzz-tested harness plus Rust, Kotlin, and TypeScript reference adapters that prove deterministic encoders agree byte-for-byte and strict decoders reject non-canonical input.
