Create Business Records That Can't Be Questioned

When regulators, auditors, or courts ask 'when did this document exist?' — have a cryptographic answer, not just your word.

No blockchain expertise required.

The Document Integrity Problem

Every business runs on documents. Contracts, financial reports, compliance filings, board minutes, employee records, policy documents, audit trails. These documents are created, revised, stored, and — when something goes wrong — scrutinized.

The critical question in any dispute, audit, or investigation is always the same:

“Is this document authentic? Did it exist on the date you claim? Has it been modified?”

And most businesses can’t prove it. They have:

None of these are truly independent. They all require trusting the organization’s own systems — the exact thing being questioned in a dispute.

Why Internal Systems Aren’t Enough

Consider these scenarios:

Scenario 1: Regulatory audit A regulator asks when your compliance policy was last updated. Your DMS says “January 15.” But your IT team has the ability to change that date. The regulator knows this. Your internal timestamp is evidence, but it’s weak evidence — it requires trusting your systems.

Scenario 2: Contract dispute You claim a contract was signed on March 1. The other party claims it was backdated. Your only proof is your internal file system and email records. In discovery, opposing counsel will question the integrity of every timestamp your systems produce.

Scenario 3: Fraud investigation An employee is suspected of altering financial records. How do you prove which version of the spreadsheet is authentic? Your internal audit trail could itself be compromised if the employee had system access.

In all three cases, you need external, independent, tamper-proof evidence of when your documents existed.

Blockchain Timestamps as Independent Evidence

A blockchain timestamp anchors a document’s SHA-256 hash to a public ledger that your organization doesn’t control. This means:

This transforms document integrity from “trust our internal records” to “verify it yourself on the blockchain.”

Implementation Strategies

Strategy 1: Critical documents only

Timestamp contracts, compliance filings, financial statements, board resolutions, and audit reports. Low volume, high impact.

Cost: A $15 Micro pack or included plan credits can cover months of critical-document protection for most small businesses.

Strategy 2: Comprehensive coverage

Timestamp all documents at creation and each revision. Integrate with your DMS via the TimeProof API.

Cost: High-volume environments usually map to 200+ scheduled credits per month, covered by pack top-ups or plan credits.

Add Legal-Grade to documents likely to face legal scrutiny. The evidence package includes the Courtroom-Ready PDF, JSON metadata, and JWS identity attestation for formal review.

Cost: Legal-Grade adds Starter and Pro: 50 credits up to 25 files, then +2/file. Business: 25 credits up to 25 files, then +1/file. Enterprise: included.

Industries Where This Matters Most

Financial services

SEC Rule 17a-4 requires broker-dealers to preserve records in formats that prevent alteration. Blockchain timestamps create a compliance layer that’s architecturally tamper-proof.

Healthcare

HIPAA requires maintaining audit trails for protected health information access. Timestamped access logs provide blockchain-backed evidence of who accessed what and when.

Law firms handling evidence, contracts, and compliance documents need to maintain chain-of-custody integrity. Blockchain timestamps add a verification layer that strengthens evidentiary standing.

Manufacturing

ISO quality management systems require document control with revision history. Blockchain timestamps provide independent proof of when specifications, procedures, and test results were created and updated.

Government contracting

Federal contractors must maintain detailed records of communications, cost accounting, and deliverables. Independent timestamps strengthen the credibility of these records in audits and disputes.

What You Receive

For each timestamped document:

Standard (IT or ST):

With Legal-Grade: All of the above, plus:

Getting Started for Your Organization

  1. Identify your highest-risk documents — those most likely to face questions about authenticity or timing
  2. Start with manual timestamping — use the TimeProof dashboard to timestamp a small set of critical documents
  3. Evaluate the output — review the certificates, verify on Polygonscan, understand what you’re receiving
  4. Scale with the API — integrate timestamping into your existing document workflows
  5. Add Legal-Grade where needed — for documents with high litigation or regulatory risk

The cost to protect your most important 50 documents? Five dollars.

1

Identify critical documents

Contracts, compliance reports, financial statements, board minutes, policy documents, audit trails — anything that might face scrutiny about when it was created or whether it's been modified.

2

Timestamp at creation

Upload each document to TimeProof at the moment it's finalized. The SHA-256 hash anchors to the blockchain, creating an immutable record of the exact file at that exact time.

3

Timestamp at each revision

When documents are updated, timestamp the new version. This creates a verifiable version history showing exactly what changed and when.

4

Store certificates alongside originals

Keep your timestamp certificates with your document management system. Each certificate includes the transaction ID, hash, and block number for independent verification.

5

Present evidence when needed

During audits, litigation, or regulatory inquiries, your blockchain-anchored records provide proof of document integrity that's independent of your internal systems.

What You Receive

Every Timestamp Includes:

📄

PDF Certificate

Readable proof showing the file hash, timestamp, and blockchain reference.

🔗

Polygonscan Link

Direct public verification of the on-chain anchor.

Verified Instant Timestamps Also Include:

Verified Identity Badge — Verified instant timestamps add an identity attestation badge to the certificate so reviewers can see the anchor came from a verified account.

Legal-Grade Upgrade Adds:

⚖️

Courtroom-Ready PDF

Presentation-ready evidence certificate for counsel, auditors, or formal review.

📋

JSON Metadata

Machine-readable timestamp data for technical or programmatic verification.

🔐

Identity Attestation (JWS)

Cryptographically signed proof that verifies through the public JWKS endpoint.

🗂️

Complete Evidence ZIP

Single download containing the core evidence package and bundled supporting proof materials.

The Complete Evidence ZIP bundles supporting proof materials such as the Merkle proof, verification guide, and checksums so third parties can review the package without contacting TimeProof.

Frequently Asked Questions

How is this different from our existing document management system?
Your DMS records when a document was uploaded to your system — but your IT team (or an attacker) could modify those timestamps. A blockchain timestamp is recorded on a public, decentralized ledger that your organization doesn't control. It's third-party verification without needing a third party's ongoing involvement.
Does this satisfy regulatory requirements?
Blockchain timestamps strengthen regulatory compliance by providing tamper-evident records. The EU's eIDAS regulation explicitly recognizes blockchain-based timestamps. SEC Rule 17a-4 requires broker-dealers to maintain records in a non-rewritable, non-erasable format — blockchain anchoring meets this standard. Consult your compliance officer for your specific regulatory framework.
Can we integrate this with our existing workflow?
Yes. TimeProof offers an API for programmatic timestamping, allowing integration with document management systems, CI/CD pipelines, ERP systems, and custom workflows. Batch timestamping via the API means you can timestamp thousands of documents automatically.
What about document confidentiality?
Your documents never leave your systems. TimeProof uses client-side hashing — only the SHA-256 hash (a 64-character string) touches TimeProof's servers. It's mathematically impossible to reconstruct your document from its hash. Even confidential financial statements, trade secrets, and privileged communications can be timestamped safely.
How do we verify a timestamp years later?
The Polygon blockchain is designed for permanence. Verify by: (1) recalculating the file's SHA-256 hash, (2) checking the transaction on Polygonscan using the ID from your certificate, (3) confirming the on-chain hash matches. This works regardless of whether TimeProof exists in the future.
