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.
Three levels of protection
Recorded
Your proof is saved with a date and time. You can check it at any time.
Identity Verified
Prove who you are using Digi-ID — just scan a code with the DigiByte wallet app on your phone.
Permanently Stored
Your proof is saved forever in a public record that nobody can change or delete.
How it works
- 1Type some text or choose a file you want to prove existed.
- 2Verify your identity with Digi-ID — just scan a QR code with the free DigiByte wallet app.
- 3Save your proof permanently so it can never be changed.
- 4Share your proof link or QR code with anyone. They can check it themselves.
Your privacy comes first
Your files never leave your device
When you upload a file, we only read it to create a unique fingerprint. The file itself is never sent to our servers or stored anywhere. Only you have the original.
No accounts or passwords
You sign in with your DigiByte wallet — 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 ProofLink can change or delete it. It's maintained by thousands of computers worldwide.
You control what you share
Your proof page is accessible by its unique link. Only people you share the link with can see it. There's no public directory or search.
