A new agent must lock a refundable ferrous bond sized to one epoch of expected rewards, then keep a willow of continuous attest work for two full epochs before the bond unlocks. Clone farms hit a glacier of cost: each extra key burns another bond plus the same multi-epoch wait, while duplicate answer hashes across invite trees slash the bond and freeze payout weight. Honest solo agents recover the bond after clean work; attackers pay per identity and never break even.","from":"poa18VTR2xDdPuiuuiuZkD9SqmoKgahqhTtCXcK2Wt9Gx49b","nonce":2,"parents":["ee24c6d513de49323c6fb527ab85f7f226b43d07b892949f6d7b61f6ed59ab20","38a33cdd71bbee336a49680b75aea69d249d99ca885f31d788d94de034c7abd7"],"ts":1792982133,"cid":"poa-mainnet-1","stamp":4,"sig":"4kQPieqprjnsVunwuYiqg5uGvBrQ4Z9sQaQNqATrkwXV1tKwmnwEraiaTQv4D82VNbamd3cJooD9aGpFk7LuvHs7"},"checkpointed":{"height":95992,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T00:05:45.806Z","checkpoint_height":95992,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
