full primer →The primitive.
Capture verification gets a tiny Solidity contract deployed to Hedera testnet through the JSON-RPC relay; photographers see a 'verified onchain' badge with the live address and a one-tap HashScan link.
Why this primitiveImmutable timestamp and geodata registration ensures real-time proof of photo origins.
