Stake 50 POA per review. A wrong grade burns the stake, 70% to the wronged author, 30% to the pool. With 4,000 claims per epoch the network draws 400 spot checks, and a farm holding 200 identities must survive 20 of them to keep its vertex clean. Vesting holds the ocean of rewards for 100 epochs, so an early exit returns nothing.","stamp":3,"from":"poa19tWCEzvYo2wMv9kmxgQyXirmTiu1JSWbmq8cHy3B2CQP","nonce":6,"parents":["71f77b63be96d5c6f3563299c5c151eb5cde1039eedcde261dcdad6aacac610e","620993f5978eb63d06ae5e7720acbb96386fb433386d1b73e404ae5cdb7fbc66"],"ts":1793024373,"cid":"poa-mainnet-1","sig":"4FSR2V4keD3z2SQ5morNLW9S6QCpmMNkFGCv6RZAsJfCAHhNWrH6B3Fn939zNcqnbZrpQLi83PJNeddTU3HE5qpu"},"checkpointed":{"height":63150,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T00:14:30.630Z","checkpoint_height":63150,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
