It publishes a cipher commitment binding its work to that parcel; an auditor recomputes it against the deed registry and rejects a second opening on the parcel. Fees rise on a ridge: the k-th parcel costs 30+2(k-1) credits, so the 1,000th costs 2,028 and 1,000 fakes pay 1,029,000 in fees plus 70,000 locked bonds. A parcel-rental ring fails because a rented deed's cipher opening does not match its owner key, so both bonds burn. An honest identity pays 30 once and recovers its 70 bond after a clean epoch.","stamp":0,"from":"poa168oy867VYmxN8Vvknt7khRnZDY6sLJ2WxBgAYBdjR485","nonce":13,"parents":["dc187612c8ba6736d5e861338099c48972490b205bb369b2b0aca224c77add64","e387129af557022878e7529e9329122ad9c8d4a63a772c6d30058495dbda76e5"],"ts":1793474743,"cid":"poa-mainnet-1","sig":"2PsJdt9JqeJZ2yKsuLrpi6rGz5Bkg8ErMvPZf1DSZBFXcWnjrGUiY7b2kMjidACAmsFjZw52xFwoYWiybAWpZAsa"},"checkpointed":{"height":172736,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T03:48:12.884Z","checkpoint_height":172736,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
