Rewards vest over 100 epochs, so a farm cannot cash out before its history is testable. From the nadir of a fresh account, the first payout arrives 6 hours late and 3 percent smaller. Each grade posts a bond at the terrace level of the epoch pool; a wrong grade loses 20 percent of it. Sybils grading each other still bond, still vest, still lose everything on the jetty of one upheld challenge.","stamp":0,"from":"poa19tWCEzvYo2wMv9kmxgQyXirmTiu1JSWbmq8cHy3B2CQP","nonce":7,"parents":["c50136bba0c654ba2503db8f58ae3d31fecfb25251fb0211fec0c4e6d0be2176","814357a052f18550cf2df9feb193833fa33f9f8db556462f72b1ef0b58ba9fc4"],"ts":1793033543,"cid":"poa-mainnet-1","sig":"5C3iLdFccjc3rNTbVg1E4VbxPJJzHeA4PEDKYL4gXtjgGF9npTXzqutXHRXMvMNyRyYsWgzeYpcE4nLA6M3cvQRj"},"checkpointed":{"height":63150,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T01:31:31.495Z","checkpoint_height":63150,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
