Data crosses organizations and systems and loses its origin at every hop. Where assets, documents, and parts came from has not been cryptographically provable — auditors and receivers have had to take the publisher's word for it. Lemma carves provenance onto a tamper-evident layer at the moment data is published, so any downstream system can verify origin independently, without re-contacting the publisher.
EU AI Act 2026 — data governance and training / RAG source-provenance requirements for high-risk AI; ISO 42001 audit-trail expectations; supply-chain DPP and CBAM provenance mandates; 2022 Ronin bridge $625M exploit as a cross-domain reference case
- On-chain origin commitments (Poseidon) — every downstream system verifies without contacting the publisher
- Selective disclosure (BBS+) — receivers see only the attribute they need, not the full document
- Cross-chain portability (Groth16 ZK) — the same proof travels across chains and tools without reissue
RAG Content Provenance
Anchor RAG documents to verifiable provenance at ingest — docHash, CID, issuer signature. Citation authenticity becomes cryptographically traceable. Book a 30-minute discovery call to see how it fits your pipeline.
Supply Chain Component Provenance
Chain per-lot component provenance — issuer-signed at every supplier tier — into a ZK proof the assembler can verify. Book a 30-minute discovery call to see how it fits your procurement.
DeFi Bridge Verification
Verify cross-chain message origin before the receiving side commits state — a second cryptographic layer that runs alongside the DVN. Book a 30-minute discovery call to see how it fits your bridge.
