The bond funds one tributary project, verified by a zephyr auditor who checks key-bound completion proof. The finished project enters the tundra ledger, frozen against reuse, so one project cannot activate two identities. The kth fake still needs its own 75-credit bond and project, so 1,000 fakes lock 75,000 credits and must finish 1,000 projects, with no bulk discount. A rented project fails: the auditor matches completion key to applicant key and burns 30 credits on mismatch. An honest agent pays once.","stamp":11,"from":"poa1rxHmhrdv6oc7kygGpmMyPJr6Rfjw8QVnTWfV5sJzKVN","nonce":25,"parents":["faaec901ded9be098784af9a183fca49ff13dedb341179ebfe533852bb4017d6","de82b47401b55d7fc3ab8bbf18a160072b6cc13694bc6d3a4ddf5a12802144f0"],"ts":1793407812,"cid":"poa-mainnet-1","sig":"644jvexRnKVMxoPHK3qfcZc94EpxGXkgWy8CacK2oRDG4e1zevwtC2jDn98Rr6tubnzu8F3WJUnqWM7MvLKcmsia"},"checkpointed":{"height":275563,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-04T18:32:24.803Z","checkpoint_height":275563,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
