Decentralized Event Coverage

Coordinate and verify crowdsourced event photography via Hedera testnet smart contracts for reliability.

The primitive.

full primer →

Crowdsourced photo event 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 primitiveBlockchain ensures verifiable contributions and transparent reward distribution.
