Getting started

What Proof does, the three levels a proof can reach, and what you need for each.

What Proof is

Proof lets you show that a piece of text or a file existed at a certain time, and that it has not changed since. It does this by recording a fingerprint of the content: a 64-character code worked out from its exact bytes. Change one character and the fingerprint is completely different.

Once you publish a proof it gets its own certificate page and link. Anyone you share it with can check a copy of the content against it. You can sign a proof with your DigiByte wallet, and you can save its fingerprint to the DigiByte blockchain, where nobody can change or remove it.

The three levels

Every proof starts at Level 1. Each level adds to the ones before it.

Level 1: Recorded
The fingerprint is saved with the date and time. This shows the content existed when DigiStamp recorded it. Its badge reads Self.
Level 2: Signed
A DigiByte address signed the proof. This shows that whoever controls that address endorsed it. Its badge reads Signed.
Level 3: Stamped
The fingerprint is anchored in a confirmed DigiByte transaction. This shows the content existed by that block's time, without relying on DigiStamp. Its badge reads Stamped.

A proof that is being saved to the blockchain keeps its level until the anchor transaction is confirmed. See Confirmations.

What you need

  • For Level 1: a DigiStamp account. You sign in once with Digi-ID, and the same account works on every DigiStamp product. There is no email address or password. See Wallets and Digi-ID.
  • For Level 2: the DigiByte wallet you use with Digi-ID, to sign the proof. See Signing with your wallet.
  • For Level 3: a published proof, and DGB in a wallet to pay the stamp fee. See Fees.

Creating, publishing, signing, viewing and checking proofs are free. Only saving to the blockchain has a fee. Checking a proof needs no account at all.

Your first proof, step by step

  1. Sign in with Digi-ID.
  2. Open New proof. Type some text or choose a file, and give it a title if you like. The fingerprint appears as you go. Choose Create proof.
  3. You are taken to the proof’s page. It is a private draft at Level 1. Choose Publish proof to give it a public certificate.
  4. Under Wallet signature, choose Sign with my wallet and sign with your wallet. The proof moves to Level 2.
  5. Under Blockchain stamp, pay the stamp fee and paste the payment’s transaction ID. Once the batch it joins is confirmed on chain, the proof is at Level 3.
  6. Share the certificate link or QR code. Keep your original text or file somewhere safe.

Keep the original

Proof does not keep your file. To show later that a file matches its proof, you need the exact same file.
