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.
The system is 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).
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.
How DAG anchoring works, AES & QES positioning, and why it’s more secure than incumbents.
