E-signature is a massive market, but the dominant systems are still fundamentally centralized. Certus Ledger’s differentiation is structural: ledger-anchored ceremony evidence that can be verified independently.
Incumbent providers typically rely on centralized audit trails and platform control for evidence packaging. In high-stakes scenarios (regulated industries, cross-border commerce, disputes), buyers increasingly demand stronger, independently verifiable proof.
Certus Ledger anchors ceremony proofs on a DAG so that document integrity, ceremony sequencing, and key metadata are tamper-evident and independently verifiable — reducing reliance on vendor trust and internal logs.

“Ledger-anchored ceremony proof” is a clear, defensible message for security teams, auditors, and regulators.
AES/QES-aligned architecture with an integration path for QTSPs supports regulated buyers and cross-border transactions.
Disputes, audits, and high-risk workflows expose the limits of centralized logs — creating a premium reason to switch.
Start with high-assurance segments, expand into broader e-sign once trust is established.
Most DPP pilots store lifecycle data in platform databases; Certus Ledger adds an external anchoring layer so DPP claims can be verified independently—without trusting the operator.
