Invoance

Invoance provides cryptographic proof infrastructure designed to create tamper-evident, independently verifiable records for business-critical data. It addresses the need for compliance and finance teams to generate durable, auditable evidence of events, documents, approvals, and AI outputs, ensuring that regulators, boards, auditors, and lenders can verify the existence, timing, and integrity of records. The platform emphasizes that critical records require more than just storage—they require cryptographic proof to establish trust and accountability.

The system offers features such as a tamper-evident proof layer for records, approvals, AI outputs, and audit evidence. Notable components include an Event Ledger, Document Anchor, and AI Attestation. Invoance processes records by ingesting payloads, canonicalizing them, generating SHA-256 hashes, validating idempotency, applying Ed25519 tenant signatures, and anchoring ledger entries. Document integrity is maintained through cryptographic anchoring, making every version traceable, while event accountability is achieved by sealing events into an append-only, tamper-evident ledger. For AI transparency, the platform attests to AI outputs with verifiable, auditable proof, capturing both inputs and outputs and hashing them for verification purposes.

Designed for external scrutiny, Invoance captures evidence at the moment actions occur, preserving the surrounding technical context for later verification. The platform ensures deterministic input, where identical inputs yield identical proofs, and maintains an append-only history so that any attempt to alter records becomes immediately detectable. Independent validation is possible without access to internal systems, administrators, or vendor assurances, and every event is Ed25519-signed, allowing for offline verification without requiring an account.

Invoance is positioned as an enterprise-grade audit logging and verification infrastructure that is developer-friendly and built for environments where records may be questioned by auditors, counterparties, or regulators. It offers features such as filtering audit logs by actor, action, target, or date, and provides signed audit logs for a range of business events, including policy changes, approvals, and data exports.
