Certus Ledger is a business-first signing platform engineered for high-assurance outcomes: every step of the signing ceremony is anchored on a distributed acyclic graph (DAG), producing independent, durable proof of integrity — beyond vendor-controlled logs.
Incumbents ask the market to trust centralized audit logs and vendor-controlled event trails. Certus Ledger anchors ceremony proofs on a DAG so integrity can be validated independently.
Built around tamper-evidence, signer uniqueness controls, and verifiable sequencing from prepare → sign → finalize.
Architected for cross-border workflows and optional QES integration via Qualified Trust Service Providers (QTSPs).
Most DPP pilots keep lifecycle events in platform databases. Certus Ledger adds an independent anchoring layer so DPP claims can be validated without privileged access to the operator’s systems.
When disputes happen, “trust our logs” is not enough. Certus Ledger produces evidence that is cryptographically sealed and ledger-anchored.
Evidence verification does not require privileged access to a vendor’s internal systems. This reduces key-person, platform, and insider-risk scenarios.
The evidence chain is designed to remain verifiable long after execution, across system migrations and provider changes.
Anchoring publishes a cryptographic commitment (hash / Merkle root) of each material event to an external, append-only public ledger—so later changes become detectable and verification remains independent.
Certus Ledger anchors event boundaries and final artifacts while keeping sensitive content off-ledger.
How DAG anchoring works, AES & QES positioning, and why it’s more secure than incumbents.
How Certus Ledger extends from signing into product lifecycle evidence—supporting independent verification for circularity, compliance, and cross-border audits.
