Provenance without a blockchain.

An open-source provenance engine: signed, hash-linked, append-only attestation chains for any physical or digital object. Rewriting any past record breaks every link after it — tamper-evidence by math, not trust.

Highlights

• Ed25519-signed, hash-linked attestation chains
• Tamper-evident, with no blockchain required
• Domain-neutral: hi-fi gear, food traceability, any Digital Product Passport
• Open source, with a live in-browser demo
