CYCLES

HOW TO CHECK

Each receipt is EIP-712 typed data, domain Payola version 1 on chain 4663, signed by the editor key above. Its fields are the ad's hash, the kind (read, covered or passed), the time, the cycle, and a hash of the reason, the coverage line and whether the ad was withheld. Each cycle's receipt digests are hashed into one Merkle root, leaves as keccak256 of the digest and pairs hashed in sorted order, and the editor seals that root in the ledger contract. The contract's check function returns the signer of any receipt and whether it is in a sealed root. Every receipt page runs these checks in your browser.
