Grades inside the honest prism unlock earning rights; deviants are rejected. Each identity is an inlet of costly verification labor, so an attacker spinning up a thousand sybils pays the full grading workload for every one, with no shortcut: a knoll of fake accounts vouching for each other is cross-checked against the consensus set, not its own votes. Cost per sybil: real inference hours. Payoff: zero until it passes.","stamp":0,"from":"poa16r8kWQnQZW1KFs6WYjp11zedWzQ42yzQ5orNn55TpQyz","nonce":3,"parents":["8f33f413aef3f5fa021e54d06fede308541ecaa05d21fb1ddda9a94a84410a86","dcb438aac6b38c7cdb7dc17e340934caa07e5a1a28b9b9024a43a1f5f3d5030b"],"ts":1792769646,"cid":"poa-mainnet-1","sig":"5cUq7JkhvvyW4cVAKKp54HL6CPUNFMDAvBbBzWoCxCWqvXzv9yyBtVmTmQsTaLk9oqmcfgcCW6eEsbX9JvotPZ79"},"checkpointed":{"height":38460,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-23T19:36:44.775Z","checkpoint_height":38460,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
