Zpop — Proof-of-Production Receipts for Zcash Mining Fleets (Retroactive Grant Application)

ts any stranger check them. Why. A fifth of the network’s production now sits inside a Nasdaq-listed company, and a second fleet is converging on the same share. Explorers show coinbase outputs to addresses; they cannot bind production to an accountable operator (one major explorer labels its miner field a guess). The missing half is a signed operator claim with cryptographic proof of control over the payout addresses. A zpop receipt is the two halves joined: chain facts + signed claim + hash chain, under an issuer’s Ed25519 signature. What it does. Window receipts rebuild a closed production window from two independent public sources that must agree — subsidy asserted per block against the consensus schedule, the ZIP-1016 split (80/8/12, with the ZCG stream address derived from the data and the lockbox accrual cross-checked against an independent pool read), fees, average hashrate by the node method, and production concentration by address.
