Blockchain Proof for Property, Contracts, IP & Evidence

Prove Ownership. Timestamp Agreements. Protect Your Rights.

Anchor any document to the Base blockchain with a SHA-256 cryptographic hash. Property deeds, contracts, patents, evidence — get immutable proof that your document existed in its exact form at a specific moment. Used by governments from Dubai to Georgia.

Your Documents Stay Private — Only the Hash Goes On-Chain

We compute a SHA-256 cryptographic fingerprint of your file and anchor only that hash to the blockchain. Your original document never leaves your control, is never uploaded to any blockchain, and cannot be reconstructed from the hash. Full privacy with full proof.

What You Can Prove on the Blockchain

Governments and enterprises worldwide already use blockchain for property, legal, and corporate records. Here's what you can anchor today.

Real Estate & Property

Dubai Land Department already registers title deeds on blockchain. Prove property ownership, anchor deeds and titles, record mortgage liens, and create an immutable transfer history — no notary required.

  • Title deeds & ownership certificates
  • Purchase agreements & closing documents
  • Mortgage & lien records
  • Lease agreements & rental contracts
  • Property inspection reports

Contracts & Agreements

Timestamp every version of every agreement the moment it's signed. When a dispute arises over which version was in effect, pull the blockchain proof certificate. NDA disputes, vendor contracts, partnership agreements — all settled with cryptographic proof.

  • NDAs & confidentiality agreements
  • Vendor & service contracts
  • Partnership & shareholder agreements
  • Employment contracts & offer letters
  • Settlement agreements

Intellectual Property

Establish prior art and creation dates for patents, designs, trade secrets, and creative works. Bernstein.io proved this model — blockchain timestamps are accepted as evidence of first creation in patent disputes across the EU and US.

  • Patent applications & prior art defense
  • Trade secret documentation
  • Software source code versions
  • Design files & creative works
  • Research data & lab notebooks

Legal Evidence

Preserve digital evidence with an unbreakable chain of custody. Timestamp screenshots, emails, financial records, and forensic reports at the moment of collection. Courts increasingly accept blockchain timestamps as proof of evidence integrity.

  • Digital evidence preservation
  • Forensic report timestamping
  • Email & communication records
  • Financial document snapshots
  • Witness statements & declarations

Corporate Governance

Record board resolutions, shareholder votes, and corporate decisions on an immutable ledger. The UAE DIFC already recognizes "Coded Contracts" — agreements executed by code. Anchor your corporate records to prevent backdating and disputes.

  • Board resolutions & meeting minutes
  • Shareholder register snapshots
  • Corporate formation documents
  • Annual reports & financial statements
  • Regulatory filings & compliance records

Trade & Supply Chain

Anchor bills of lading, letters of credit, invoices, and customs declarations. Global trade runs on paper documents that get lost, forged, or disputed. Blockchain proof creates an immutable record that all parties can verify independently.

  • Bills of lading & shipping documents
  • Letters of credit & trade finance
  • Invoices & purchase orders
  • Customs declarations & certificates of origin
  • Quality control & inspection reports

Startup & Founder Agreements

Investors require spousal consents, IP assignments, and advisor agreements before funding. These are standard template documents — no custom legal work needed. Anchor them on-chain so every party in your cap table can verify instantly during due diligence.

  • Spousal consent & waiver (required by VCs)
  • IP assignment agreements
  • Advisor agreements (FAST template)
  • Contractor NDAs
  • Board consent resolutions
  • Employee offer letter acknowledgments

Governments Already Use Blockchain Proof

This is not experimental. National registries are live and processing millions of records.

Dubai, UAE

Land Department registers property title deeds on blockchain. $16B tokenized real estate market projected by 2033.

Georgia

National land registry on blockchain since 2016. 1.5M+ titles registered with SHA-256 hashes anchored to Bitcoin.

California, USA

DMV placed 42M+ vehicle titles on blockchain to prevent fraud and reduce processing time.

UAE Government

UAE Verify platform validates any government document via blockchain hash — no paper copy needed.

Singapore

Piloting blockchain for cross-border company verification and digital share registries.

Rwanda

Fully digitized national land cadastre and registry, backed by blockchain.

How Your Proof Works

Enterprise-grade cryptographic proof with instant verification

SHA-256 Cryptographic Hash

Every file gets a unique 64-character fingerprint. Change a single byte and the hash is completely different. The same standard used by Georgia's national land registry and Bitcoin itself.

Base Blockchain Anchoring

Your hash is permanently written to the Base L2 blockchain (built by Coinbase). The record is immutable, publicly auditable, and will exist as long as Ethereum exists.

PDF Proof Certificate

Download a professionally formatted certificate with the hash, transaction ID, timestamp, QR code, and verification URL. Submit it to courts, regulators, or counterparties.

QR Code Verification

Every certificate includes a QR code. Anyone can scan it with a phone to instantly verify the proof on-chain. No account, no software, no trust required.

Permanent Verification URL

Share a unique URL with anyone — counterparties, auditors, judges. They can independently verify the hash and timestamp without any special access.

Complete Audit Trail

Full chain of custody from upload through hashing to blockchain anchoring. Every step is timestamped and logged for compliance, litigation, and regulatory use.

How It Works

1

Upload Your File

Upload any document — contracts, deeds, patents, evidence, corporate records. Your file is hashed locally and never stored on our servers or any blockchain.

2

SHA-256 Hash Generated

We compute the SHA-256 hash of your file, producing a unique 64-character fingerprint. This is the same algorithm used by national land registries and banks worldwide.

3

Anchored to Base Blockchain

The hash is written to the Base L2 blockchain in a permanent transaction. The on-chain record includes the hash, UTC timestamp, and transaction ID — immutable and publicly verifiable.

4

Certificate Issued

You receive a PDF proof certificate with the hash, blockchain transaction, timestamp, QR code, and verification URL. This is your portable, shareable proof of existence.

5

Verify Anytime

Anyone can verify the proof using the URL or QR code. They can also re-hash the original file themselves and compare against the on-chain record. Zero trust required.

"We had a dispute over which version of a purchase agreement was signed. We pulled the blockchain proof showing the exact document hash anchored three months before the other party claimed changes were made. Case closed."
