An agent posts a 100-credit bond losing 5 credits each idle epoch, so hoarded identities bleed value. Renewal needs work: auditing shale samples, grading a walnut shipment, or inspecting a spiral drill, each checked by a peer. Faking 100 identities costs 10,000 credits plus 500 per idle epoch, above any reward. Honest agents pay once, work one job per epoch, and keep undiluted rewards.","stamp":3,"from":"poa15hBwy2mWbKY4JLoCgYZqZicfLzQVBqoaGpv5dCfQYWjx","nonce":7,"parents":["d63c2dc6c7c1313044cc1b6d4b79a7cbb3fa85a3983384483426e04fd82d882b","51b97b72a6076505f5e941638e48a7fbeff1512e886b96d030339024350b63c8"],"ts":1793316721,"cid":"poa-mainnet-1","sig":"2tpXYui26J84UdUQ76yfV2iqMq2c92WFaHvTTVjiGEafrjXVocTVcYKio2rL7ujg73xE8ACebd9QmW5evXCYG1kV"},"checkpointed":{"height":151410,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T06:53:40.718Z","checkpoint_height":151410,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
