JurisChain gives you tamper-evident proof of existence, integrity and time for any document — sealed with a cryptographic fingerprint and independently verifiable. Your files never leave your device.
Whenever a date, a signature or an unaltered record could be challenged, JurisChain gives you defensible evidence.
Seal ID checks, payment instructions and property documents to evidence they were unaltered — a defensible record against payment-diversion and impersonation fraud.
Establish an immutable chain of custody for emails, logs, photos and digital records, with a verifiable certificate you can put before a tribunal.
Prove a design, manuscript or codebase existed on a given date — independent evidence of prior art before registration or a dispute.
Anchor the exact signed version of an agreement so neither party can later substitute or alter it without it being obvious.
Demonstrate to an auditor that a consent, policy or record existed and has not been tampered with — UK GDPR friendly by design.
Add a verification layer to your own platform. White-label proof and certificates for your customers (wills, probate, proptech, RegTech).
Proof without ever handing over your documents.
Your browser computes a SHA-256 fingerprint of the file. The document itself never leaves your device.
The fingerprint is sealed with a timestamp and metadata, and can be anchored to a public blockchain for independent, trusted time.
You receive a portable proof file and a verifiable certificate — ready to share with a court, counterparty or beneficiary.
Anyone can re-hash the file and confirm it matches the sealed record. If a single byte changed, the check fails.
Start free. Scale when your volume does. Prices in GBP, excl. VAT.
Tell us your use case and we'll set you up. Pilots welcome — especially conveyancing, litigation and IP teams.
