Blockchain-Based Document Proof
Tamper-Proof Document Timestamping Service
Instantly generate cryptographic proof that your documents existed at a specific time and were never modified —
verifiable by anyone with blockchain.
Our solution
Businesses need proof — not trust
Problem
In critical business processes, relying on internal systems or trust between parties is often not enough.
- Documents can be modified after signing without leaving reliable evidence.
- Traditional timestamps and logs can be disputed or backdated.
- Auditors, regulators, and courts require independent, verifiable proof.
Solution
Our service provides a neutral and verifiable way to prove document integrity.
- Generate a cryptographic hash of the document.
- Anchor the hash on a public blockchain as a timestamp.
- Enable anyone to independently verify the proof at any time.
Simple process
How it works
1
Upload your document to your browser
Upload a document and generate its hash locally. The file itself never needs to leave your system.
2
We generate a cryptographic hash
A unique digital fingerprint is created for the document. Even the smallest change would produce a different hash.
3
We record the hash in the blockchain
The hash is recorded on a public blockchain, creating an immutable timestamp that cannot be altered or backdated.
4
Anyone can verify the proof later
At any time, anyone can recalculate the hash and verify it against the blockchain record — independently and without relying on us.
