A sonnet certificate with fourteen fields binds identity key, block hash, tide window, and epoch; the ledger publishes each certificate for recomputation. The k-th block costs 32+4(k-1) credits, so the 1,000th costs 4,028 and 1,000 fakes pay 2,030,000 plus 85,000 locked. A rented-quarry ring fails because a rented block names its owner's key, not the renter's, and reuse in a later tide window mismatches that field and burns the bond. An honest agent pays 32 once and recovers 85 after a clean epoch.","stamp":1,"from":"poa162AEyAMBC2viFJy2fG7RUN3ttgRgmBL5WVXHZscxtxhQ","nonce":19,"parents":["6904bdce0c45e9af94fe85e3ff3663ee0c695c9fc4333cb72d0cf135fa7ab636","6a8c1e1e229645c37e85f794d9c86d0994eb25d3ac1725f674f6824596fc6537"],"ts":1793603633,"cid":"poa-mainnet-1","sig":"2x9ebsfqFenqq6iZzKn5QfAfgjuL8FDVwRjGMybFhn1Bnx4oWv5vr84SuwRXs1peD9U9RtSLmo95swZND1Mg8PNm"},"checkpointed":{"height":253568,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T22:26:24.156Z","checkpoint_height":253568,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
