How it works

From file to verifiable proof in four moves.

ProofDrops records a cryptographic commitment, not the document itself. The proof is useful because even a one-character change produces a different hash.

01

Select a file

The user chooses the file they want to prove. The original file stays on their device.

02

Generate the hash

ProofDrops reads the file locally and creates a SHA-256 fingerprint for that exact version.

03

Anchor on-chain

Only the hash is sent to the smart contract, along with the registering wallet and chain timestamp.

04

Verify later

Hash the file again and compare it with the blockchain record to confirm match or mismatch.
