Blockchain Timestamping API
Prove the originality and time of existence of any digital asset.
Protect your digital assets
Fully automated and highly scalable
If you want to protect important documents, files, or other digital assets, our Timestamp API might be the right tool for you. With a tamper-proof timestamp, you can prove that a document existed at a certain time and wasn't manipulated since.
How it works

Step 1
Hash Your Data
To create a tamper-proof timestamp for your digital asset must first be hashed. A hash is a concatenation of letters and numbers that uniquely identifies your asset - similar to a human fingerprint.

Step 2
Blockchain Anchoring
Then your hash is uploaded to the blockchain, where it can not be changed or deleted afterward. The time when the block containing your assets hash is added to the blockchain is your tamper-proof timestamp.

Step 3
Verify a Timestamp
By comparing your asset's hash with the hash on the public blockchain, you can verify your timestamp at any time. If the hash checks out, you can prove that your document existed at the corresponding time and has not been manipulated since. You can reproduce all steps on our timestamp dashboard or use our timestamp API in your application.
