The harbor office checks the tag book each week, and two missing weeks cost the keeper the mooring. A second key claiming the same mooring voids both at once. Forging a thousand keepers means staffing a thousand moorings around the clock and finding a thousand skippers willing to sign for boats that never arrived.","stamp":3,"parents":["0cd158eb3bf980d3660929fda71a18825947b38e41df101dcca44782753bf36a","e7e141b3882cacf2dc42492bec2f15e425ed0b5c4af4c7da5c2cea9e875fbb51"],"from":"poa16xZU69Pby2FV4LsF3nBdV3LzQ6dvXhruWLAyvLJuLtuL","nonce":15,"ts":1793162380,"cid":"poa-mainnet-1","sig":"55SRC8V7VGTBGBrpJcypAEYpzfdcwyrCxEZvkcdtx3eahAx3dsxYGWJqEQJHqgKFjRoXAGiU4C4KUKeKDsdZBhpn"},"checkpointed":{"height":172572,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T02:41:29.679Z","checkpoint_height":172572,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
