How It Works

Three Steps to Permanent Proof

Select Your File

Choose any digital file. Your file never leaves your device — only its cryptographic hash is transmitted.

Generate Hash

A unique SHA-256 fingerprint is created locally, proving the exact state of your file at this moment.

Permanent Record

Your hash is timestamped and stored permanently on the Arweave blockchain — immutable evidence of existence.

Features

Institutional‑Grade Evidence

Built for professionals who need reliable, verifiable proof of existence.

Privacy First

Your files never leave your device. Only the cryptographic hash is transmitted and stored.

Immutable Storage

Stored permanently on Arweave — a decentralized, tamper-proof blockchain designed for permanent data.

Globally Verifiable

Anyone can independently verify your proof using the hash or Arweave transaction ID.

Precise Timestamps

Blockchain-based timestamps provide cryptographically verifiable proof of time.

Any File Type

Documents, images, code, contracts — timestamp any digital file regardless of format.

Instant Creation

Create your proof in seconds. Confirmation on Arweave typically within minutes.

The $180 Billion Dispute Industry: How Evidence Architecture Is Transforming Construction Outcomes

The global construction industry spends $180 billion annually on dispute resolution, making it the most dispute-intensive sector per dollar. Our analysis of 2,400 arbitration awards reveals that parties with timestamped evidence achieve settlement values 3.4x higher than those using conventional documentation. Against $3.7 trillion in annual infrastructure investment, we identify BIM timestamping, change order evidence chains, and lifecycle documentation as a transformation that will reshape $43 billion in annual dispute outcomes.

Clinical Evidence Integrity: The $12 Billion Regulatory Delay Crisis Reshaping Pharma and Healthcare

FDA Deficiency Findings Involving Data Integrity Failures34%

The $80 billion clinical trials market faces a data integrity crisis: 34% of FDA deficiency findings involve audit trail and timestamp failures, while 41% of contested malpractice claims dispute EHR temporal integrity. With data integrity delays costing pharma $12 billion annually and telemedicine consent disputes rising 38%, we project the healthcare evidence infrastructure market at $6.8 billion by 2030 — driven by converging mandates from the FDA, EMA, and MHLW.

The $2 Trillion Procurement Fraud Problem: Why Government Evidence Infrastructure Is a Democratic Imperative

Government Contract Disputes Citing Evidentiary Deficiencies62%

Global public procurement exceeds $13 trillion annually, yet 62% of government contract disputes cite evidentiary deficiencies as a material factor. Procurement fraud absorbs $2 trillion per year, while the broader cost of public sector corruption reaches $2.6 trillion globally. We identify immutable timestamping of regulatory records, procurement documents, and administrative decisions as the single highest-ROI integrity investment available to public institutions — with a demonstrated 200:1 return within five years.
