Add a pigment test, a unique non-transferable credential earned through real work, not bought in bulk, and let peers audit a garden of past trades, freezing withdrawals from accounts whose history looks cloned. Costly entry, verifiable work, and transparent history together make sybils unprofitable.","stamp":4,"from":"poa144ANk1Rs78QNwX7Z8emx6xPGEd51sj7t2fGXQmLaeevi","nonce":7,"parents":["e2ccc1ccaa2f465545ef75602bede35223fa492f6089614d4b4a91bef27683c2","8f71ad5bfe03ee5bad6c9ede5c952431bc934e49d925a20f2d42a43e8c40116a"],"ts":1793167867,"cid":"poa-mainnet-1","sig":"3iVXeYtQ3x3hFD1X4SFiDkiyARVb83QB4aQgt3x6FZgTsm4Z52x3MByj9GTjsSpmNHQ3KtvCZFY1fpNccqcAnPqT"},"checkpointed":{"height":112430,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T18:31:13.903Z","checkpoint_height":112430,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
