Where Digital Content Becomes Tamper-Proof
Digital data is easy to manipulate. OriginStamp changes that. Anchor any document, file, or dataset on Bitcoin and Ethereum, and prove its existence at a specific point in time. Independently, globally, forever.
Your digital proof is only as strong as your weakest link.
Files get altered. Logs get overwritten. AI outputs get questioned. Without cryptographic proof, you have no way to verify when something existed or whether it has been changed. OriginStamp anchors a unique digital fingerprint of your data on the blockchain. The result: mathematically provable, tamper-evident proof that no admin, no hacker, and no court can dispute.
Immutable by Design
Once your hash is anchored on Bitcoin or Ethereum, nothing can change it. Not your team, not an attacker, not even us. That is the point.
Globally Verifiable
Anyone, anywhere, can independently confirm your timestamp. No special software, no account, no trust in a third party required.
Zero Blockchain Expertise
A single REST API call is all it takes. Your developers integrate in hours, not weeks. We handle the blockchain complexity so you don't have to.
Proof that holds up. In every industry.
AI Content & Provenance
Prove when and by which model content was generated. As AI regulation tightens, timestamped provenance becomes your audit trail for transparency and trust.
Compliance & Legal Proof
Automatically stamp documents, contracts, and approvals for GDPR, ISO, and audit requirements. Every change documented. Every version tamper-proof.
Critical Infrastructure & Logs
Protect access logs, camera feeds, and system events from manipulation. When an incident happens, your evidence chain is unbroken and court-ready.

How OriginStamp Timestamps Your Data
From Hash to Blockchain Proof in Seconds
Your document never leaves your system. OriginStamp generates a SHA-256 hash locally, anchors it on Bitcoin and Ethereum, and returns a verifiable certificate. The entire process takes seconds. The proof lasts forever.
Intellectual Property Protection
Ideas, designs, source code: prove when they existed. A blockchain timestamp is your first line of defense in any IP dispute, globally recognized.
Application & Audit Logs
Financial transactions, system events, access records: protect your logs from silent manipulation. When forensics begins, your evidence stands unquestioned.
Deletion & Retention Records
Document deletion events immutably for GDPR and data protection audits. Prove that records were deleted on time, not after the fact.
Everything you need for tamper-proof digital proof
Bitcoin & Ethereum Anchoring
Your hash is written to the world's most secure public blockchains. No single entity can alter or remove it.
SHA-256 Hashing
Industry-standard cryptographic fingerprinting. Your original data never leaves your system.
Verifiable Certificates
Every timestamp generates a downloadable proof certificate. Present it in audits, legal proceedings, or compliance checks.
Independent Verification
Anyone can verify your timestamp against the public blockchain. No OriginStamp account needed.
REST API
A single API call creates a timestamp. Integrate into your existing workflows in hours, not months.
Webhooks & Callbacks
Get notified automatically when your timestamp is confirmed on the blockchain. No polling required.
SDKs & Code Samples
Ready-to-use libraries for Python, Java, Node.js, and more. Your developers ship faster with battle-tested code.
Bulk Timestamping
Timestamp thousands of documents in a single batch. Ideal for log files, transaction records, and large-scale compliance workflows.
Audit-Ready Reports
Generate compliance reports with full timestamp history. One click, all the proof your auditor needs.
On-Premise Option
For regulated industries: run the hashing on your own infrastructure. Your data never touches our servers.
Retention Policies
Define how long timestamps and certificates are stored. Align with your data governance requirements.
SLA & Enterprise Support
Guaranteed uptime, dedicated support, and custom integration assistance for mission-critical deployments.
Use Case Assessment
We review your data flows, compliance requirements, and proof needs, then identify where timestamps add the most value.
Integration Blueprint
Our team designs the API integration: which data to timestamp, when to trigger, and how to store certificates.
Proof of Concept
We run a live test with your real data. You see timestamps anchored on Bitcoin and Ethereum within minutes.
Production Rollout
Full API integration, webhook setup, and certificate management. Your data is now tamper-proof at scale.
Monitoring & Optimization
We monitor timestamp volumes, blockchain confirmations, and API health. You focus on your product while we handle the proof layer.
What we stand for, and what you can expect.
Swiss Precision
OriginStamp is developed entirely in Switzerland. We build infrastructure that delivers on its promises, no compromises. That is what Swiss Made means to us.
Math, Not Promises
We guarantee data integrity through cryptographic proof, not marketing claims. Provable, auditable, and backed by 12+ years of peer-reviewed blockchain research.
API-First, Always
One REST call creates a timestamp. Our API is built for developers who want to ship fast, not wrestle with blockchain infrastructure.
