For governments, finance, health & critical infrastructure

Secure the world's most sensitive records.

Anchor your highest-stakes records as tamper-evident, independently verifiable, cryptographically anchored proof — GDPR-clean and hash-only, so nothing sensitive ever leaves your perimeter. Open protocol, nonprofit-stewarded, self-custody. No vendor to trust, nothing to lock you in.

Anchored in the EU and the US

Built for records that can't afford a doubt

Government

Public-record integrity

Decisions, registers, disclosures and case files — provably unaltered since the moment they were made, checkable by any citizen or court.

Finance

Audit & model evidence

Risk decisions, model outputs, and audit workpapers anchored as independent evidence a supervisor can verify without trusting the bank or the vendor.

Health

Clinical & consent records

Consent, provenance, and clinical-decision trails proven tamper-evident — hash-only, so no patient data is ever exposed.

Critical infrastructure

Operational provenance

Configuration, control actions, and incident records anchored to a neutral, independent timeline that survives any single system.

How it works — your data never leaves you

Hash it where it lives. The record is fingerprinted inside your perimeter. Only the hash — never the content — is ever used. GDPR-clean by construction.

Cryptographically anchored. The fingerprint is committed to the most independent timeline in existence, in the EU and the US. No money moves through you; the public chain is used purely as a neutral, tamper-evident clock.

Anyone can verify, forever. Any auditor, regulator, or counterparty can independently confirm the record is unaltered and existed when you say — with the open-source verifier, without trusting LedgerProof or any vendor.

LedgerProof manufactures tamper-evident, independently verifiable evidence — not a verdict. Your auditor, regulator, or court makes the determination; we make it provable. Proofs are tamper-evident, not tamper-proof. Hash-only and GDPR-clean by construction.

Why the most cautious institutions can adopt it

Sovereign

Self-custody, no lock-in

You hold the keys. The protocol is open and the verifier is open-source — if LedgerProof ever stopped, every record you hold keeps verifying against the public chain.

Neutral

Nonprofit-stewarded

Stewarded by a California nonprofit (501(c)(3) application in process). An open, public-interest protocol — not a vendor land-grab.

Private

Hash-only by design

The format rejects sensitive fields at parse time. Nothing readable is ever anchored — provable integrity without exposure.
