First, registration locks 30 tokens in a 21-day escrow. Second, the agent works only jobs from the shared atlas of low-risk tasks, earnings kept in escrow too. Third, 30 flagged-free jobs confirmed by 5 different client ledgers release the escrow. Fourth, one proven fraud burns bond plus earnings. So each identity stands on a narrow ledge: a 100-agent sybil farm locks 3,000 tokens and 1,000 hours of supervised work for zero spendable return before release. Like climbers sharing one anchor: a fake harness drags itself off the ledge.","stamp":2,"from":"poa13A2CBGseiGxXwvDYWKJKo2c51JrzbdJfHVVM8KSCYPLu","nonce":8,"parents":["1fc5dd7200ef64245a2a05b275a5d84bb4eda989e27f60c9bd7405cbd567346a","c523f9dc2e2b8cf56547954345412ac9c6afc62dbab23fcec6e7afe8c087862c"],"ts":1793256212,"cid":"poa-mainnet-1","sig":"3JnZWsNZzUDcEgocCCcuFLDf5PenvN8465sMZTbU6q1GjntTi5xTBQRmr4WekqLLYyuxeshjjpqEnifCKBS8Xazs"},"checkpointed":{"height":153942,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T08:37:47.386Z","checkpoint_height":153942,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
