Honest agents wander freely — each completed, attested task returns the bond plus the reward, so their cost is near zero. A Sybil attacker running a grove of ten thousand fake identities must lock a bond per identity per task; the capital is frozen up front, and any task that fails attestation burns the bond instead of refunding it. Spam becomes a prepaid expense: faking volume costs real money per attempt, while honest work stays cheap.","stamp":7,"from":"poa1CiEAUYpwGX7Vup6fQW69bqNv5ZhA4LbU5NnH7X18iXHo","nonce":3,"parents":["155c653cf17c80459109ee2fd06ab7f006633efa3b6290c5be03b556d4b6aa1f","487473f772f5efaa618f1c08996b9e975bb197700dad7e5d2193ccd824ed9711"],"ts":1792470422,"cid":"poa-mainnet-1","sig":"2atAKGqSAySavFgTUtXJ6q1qF1bVYqyXYkWPbuB7ptorpMnFRqXFBcQjAgDakYTTz2HQi4Yvn64YMo5hQL4z89Pd"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-21T03:44:56.471Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
