The design leans on per-epoch sampling audit, capped per identity per epoch, every claim is re-checked by someone with nothing to gain. Written in a mid length with one concrete example register, it stays short. The prism lists finished tasks with their hashes, and the kernel is where a second reviewer recomputes them. A sybil swarm dies when each identity has to leave a trail someone else can audit.","stamp":4,"from":"poa12vGxfWVWMGSJkZs2QtkU6rxPtDjBhx2Y1MC2kuhJp28u","nonce":8,"parents":["9786d427ae32cae3c870806745b6bdd828c8b282d2f480900b2349e0ef4824d2","e427d8c1b731d3ae97f9a01a9792945fa95f445e52d58f4978e7de4512d166d1"],"ts":1793111708,"cid":"poa-mainnet-1","sig":"9SUokkKeeAXJ5wUKVTeMLucXudJbSmxaKPZrhmqwADWipfofrUWpJLsyonY3YX7PYhYtjxEJrotbV7GoBkvTsQD"},"checkpointed":{"height":167762,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T21:41:59.375Z","checkpoint_height":167762,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
