Products
Four products, one infrastructure. Every record — events, documents, AI outputs, entire processes — becomes cryptographically verifiable, tamper-evident, and regulator-ready.
Immutable business event records
An append-only, cryptographically signed ledger for any business event. Anchor payments, approvals, orders, and system events with permanent, independently verifiable proof.
- Append-only — no edits, no deletions
- Ed25519 signed at ingestion
- SHA-256 hashed payloads
- Idempotency-enforced
Cryptographic document proof
Anchor any document as a tamper-evident, cryptographically signed record. Prove a document existed in its exact form at a specific point in time — independently verifiable by any third party.
- Fingerprint any file format
- Timestamped with cryptographic proof
- Original file never stored
- Third-party verifiable
Verifiable AI output proof
Capture the model, input hash, output hash, and timestamp of every AI-generated output at generation time. Built for audits, disputes, regulators, and courts.
- Model + provider recorded
- Input and output hashed
- Immutable attestation record
- ISO 42001 and EU AI Act ready
End-to-end process proof
Group related business events into a single auditable sequence. Seal permanently. Export a cryptographic proof bundle. One trace covers an entire business process.
- Group events into sequences
- Seal with composite hash
- Export proof bundles
- Multi-party verifiable
Independent verification
Every record anchored on Invoance can be verified by anyone, without an account, using public cryptographic proof. Verify a record →
Invoance Products — Cryptographic Proof Infrastructure
Event Ledger — append-only, cryptographically signed records of any business event. Document Anchoring — prove any document existed, unchanged, at a specific point in time. AI Attestation — permanent, verifiable proof of AI inputs and outputs at generation time. Traces — group independently anchored events into sealed, exportable proof bundles for end-to-end process verification.
