Verify any archive directly from the blockchain - no trust required
We calculate the SHA-256 hash of the archived content
Check multiple blockchains for matching hash records
Confirm when the archive was created using blockchain timestamps
Ensure the content hasn't been modified since archival
Don't trust us? Verify directly using these public blockchain explorers:
Use our open-source verification library:
// JavaScript Example
import { DropletVerifier } from '@droplet/verify';
const verifier = new DropletVerifier();
const result = await verifier.verify({
hash: '7a8f9b2c4d6e1a3f5b8d2e7c9a4b6d8e',
chains: ['cardano', 'arweave', 'ipfs']
});
console.log(result.isValid); // true
console.log(result.timestamp); // 2024-12-15T14:23:00Z
console.log(result.blocks); // { cardano: 8234567, arweave: 'tx_id' }
