⚠️ NOTICE: Deployment Testing in Progress We have recently deployed a major platform update and are currently performing post-deployment testing and validation. Please do not use this website or submit any transactions until testing is complete. Some features may be unavailable or behave unexpectedly. Thank you for your patience as we work to ensure everything is functioning correctly.
Anchored on DigiByte
Prove it existed.
Create a permanent, tamper-proof record of any text or file. Nobody can change it. Nobody can delete it. You can prove it was yours at any time.
Anyone can verify a proof without signing in.
How it works
- Sign in with Digi-ID: scan a code with your DigiByte wallet. One account works on every DigiStamp product.
- Type some text or choose a file you want to prove existed. Its fingerprint is recorded.
- Publish it, sign it with your wallet, and save it permanently to the DigiByte blockchain.
- Share the certificate link or QR code with anyone. They can check it themselves.
Three levels of protection
Each proof starts recorded. Sign it to add your identity, then anchor it on the chain to make it permanent.
Level 1
Recorded
Your proof is saved with a date and time. You can check it at any time.
Level 2
Signed
Sign it with your DigiByte wallet, so anyone can see which address stands behind it.
Level 3
Permanently Stored
Its fingerprint is saved for good in a public record that nobody can change or delete.
Your privacy comes first
Proof keeps a fingerprint, never your file. Read the privacy policy
Your files are never saved
When you prove a file, our server reads it only to create a unique fingerprint, then discards it. We keep its name and fingerprint, never the file. Text you type in is kept only if you choose to store it, and stored text is shown on the certificate.
No email or passwords
You sign in with your DigiByte wallet through Digi-ID: no email, no password, nothing to remember. Your identity is controlled by you, not us.
No one can tamper with your proof
Once your proof is saved to the blockchain, it's permanent. Not even DigiStamp can change or delete it. It's maintained by thousands of computers worldwide.
You control what you share
A new proof is a private draft. Once you publish it, its certificate is open to anyone with its link, and a signed proof is listed on its signer's public proof list. Only fingerprints go on the blockchain.

Fees, signing, privacy and checking a proof, in plain words.
