The Only Way to AI-Proof Your Evidence
Prove. Verify. Trust. TimeBinder provides blockchain file verification with cryptographic certainty, allowing you to prove when a file existed and confirm its authenticity to any court, regulator, or third party.
If you fail to timestamp a file before sharing or relying on it, you lose the ability to prove when it was created. In an era of effortless AI forgeries, blockchain file verification is the only way to defend clients, validate digital evidence, and establish truth.
Select your Files
All encryption happens on your own device. TimeBinder never sees your files!
Submit your TimeBind
TimeBinder handles everything! Locking your documents to the Blockchain is a simple click.
Receive your Certificate
Once verified on the Blockchain, your Proof of Time Certificate has all the information you need.
1. Verify a Proof of Time Certificate
Use your Proof of Time Certificate ID to confirm:
- The exact timestamp anchored on the Bitcoin blockchain.
- The block height and transaction reference (TXID).
- The TimeBind bundle’s Merkle root representing up to 10 file hashes and optional reference data.
- A clear result: Verified or Not Verified.
A “Verified” result confirms file hash verification and file integrity, backed by an immutable Bitcoin Blockchain transaction record.
2. Verify by File Hash (No Upload Required)
Paste or drop your file. Your browser computes a SHA-256 hash locally; the file never leaves your device.
- Verification requires a live blockchain view to confirm on-chain data. Only the hash is processed client-side.
- Hash verification does not search unknown records. It confirms against TimeBinds linked to your account, a presented Proof of Time Certificate/QR, or items marked for public verification.
What You’ll See on a Match
- Timestamp and confirmation depth
- Original anchor transaction (TXID)
- Shareable verifier link suitable for court bundles
Your file stays private; verification uses only the hash.
ASAP vs Pooled Verification
- ASAP: The bundle’s Merkle root appears directly in the Bitcoin OP_RETURN. Anyone can independently confirm it using the TXID from the Proof of Time Certificate. No TimeBinder access is required for verification in the future.
- Pooled: Proofs are batched every 24-36 hours. The Proof of Time Certificate does not contain the full Merkle inclusion proof. Verification requires retrieving that proof from TimeBinder’s verifier at the time of validation, since only the pooled root is on-chain.
Why the Blockchain Can’t Be Broken Even by Quantum Computers!
Since 2009, the Bitcoin blockchain has operated without a single breach, securing trillions of dollars across more than a billion transactions. Blocks are cryptographically linked and distributed across tens of thousands of computers, making the data effectively immutable. Altering any record would require rewriting the entire chain and overpowering the global network’s energy — impossible . Even quantum computing poses no real threat, as Bitcoin’s SHA-256 and elliptic curve cryptography remain resistant and can be upgraded long before quantum attacks become viable.
3. Why Lawyers and Professionals Use Blockchain File Verification
Every transaction, investigation, and dispute involves digital evidence. Without blockchain file verification, authenticity relies on trust — a concept erased by AI manipulation.
TimeBinder provides:
- Legal-grade integrity.
- Anchoring to the Bitcoin blockchain, not private servers.
- Privacy-by-design: no file uploads, only hashes.
- Independent, public verification anytime.
When your matter depends on who had the document first, blockchain file verification establishes admissible proof beyond doubt.

4. Verification Results Explained
TimeBinder compares your file hash to the TimeBind bundle metadata and the blockchain record. Results are:
| ✅ Successfully Verified | The file hash and its inclusion proof match the Merkle root on the Bitcoin blockchain. ASAP: Root appears in OP_RETURN; confirm via the TXID shown on the Proof of Time Certificate. Pooled: Verified by Merkle inclusion proof linking your leaf to the pooled root. Use the verifier or any independent Merkle tool with the provided proof data. |
| ❌ Verified Failed | No match to a recorded TimeBind. Typical reasons: • The file was modified after TimeBinding. Re-check you are using the correct, original version. |
Proof of Time Certificate and QR
The Proof of Time Certificate and its QR link identify the relevant Bitcoin transaction and Merkle root. For pooled proofs, the inclusion path is provided dynamically by TimeBinder when verifying; it is not embedded in the certificate itself.
5. AI-Proofing and Evidentiary Priority
AI can fabricate metadata, documents, and entire audit trails. Only blockchain file verification provides irrefutable proof of when a file existed.
Use it to:
- Anchor contracts before negotiations.
- Prove when reports or exhibits were finalised.
- Protect client evidence and IP assets.
- Demonstrate chain of custody for legal or forensic matters.
No blockchain timestamp = no verifiable proof.
6. Trust, Security, and Access
- Files are hashed locally; never uploaded.
- Verification is read-only and requires live blockchain data.
- No file content is logged; only SHA-256 hashes.
- Secure Google or email-based authentication.
- Anchored to Bitcoin — the world’s most secure public ledger.
Blockchain file verification makes every timestamp permanent, private, and globally auditable.
7. Roadmap Notes
Planned upgrades include:
- API and SDK integrations for automated blockchain file verification in DMS and ECM systems.
- Possible integration into other blockchains such as Ethereum, Bitcoin Cash, Dash and many others.
