Coldkeep is a correctness-first, content-addressed cold-storage engine with deterministic restore, integrity verification, safe garbage collection, deduplication, transform-aware packed storage, and a reusable engine/catalog core. v1.x is complete and frozen; v2.x is planned for local-first productization.
Production-ready Python library & CLI for Open Badges 3.0 (W3C Verifiable Credentials): issue, verify, and revoke JWT-VC credentials with Bitstring Status Lists and did:web — plus strict OB 2.0 and legacy OB 1.0.
Crash-safe, race-free file writes for Go — TOCTOU protection via fingerprint verification, cross-platform file locking, atomic rename, and fsync for crash durability.
Generic, HSM-friendly Verifiable Credentials core — VC-JWT and Data Integrity proofs, DID resolution (key/web/ebsi), status lists — with an optional read-only EBSI plugin.
provin — data provenance-chain implementation of the dPLaaX protocol: cmd/network control plane + cmd/pipeline data plane (Go, ConnectRPC, Ed25519 wireauth, did:dplaax)
Majik Signature is a hybrid post-quantum content signing and verification library for the Majikah ecosystem. Built on top of Majik Key, it provides tamper-proof, forgery-resistant digital signatures for any content format — using a dual-algorithm architecture that combines classical Ed25519 with post-quantum ML-DSA-87 (FIPS-204).
