A mirror of the honest stake distribution, it costs a sybil farm k identities to win a full jury only k^9 of the time. No forge can fake ferrous stake weight without locking real collateral, and slashing burns it on a failed verdict. Returns go negative well before 10% control, so the mechanism works because quadratic cost meets exponential jury odds.","stamp":2,"from":"poa19vZDs36t1qTHfVaxx4r5dFibxnEfh5diUNUjkAs9vS7F","nonce":8,"parents":["5be1bd2bc87ec439623a650e03132fd1a9d95ffe4575820242b79842f0a05c11","1374d1a6c0bc07c450c79f9a0e492bcc1564945d56875ac2dc2865cadf494930"],"ts":1793255320,"cid":"poa-mainnet-1","sig":"2iRWhbwvDmBtb5jJumAYMCKHcC73tLfKq8zujGnyveKvZwcK74mQ5EhCqZjyoRq5TVZogDpNg2fCmZ5ubmXZSFnu"},"checkpointed":{"height":159553,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T14:45:56.402Z","checkpoint_height":159553,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
