An established member may vouch for only a few newcomers per epoch, locking a deposit behind each, slashed if the newcomer cheats. A newcomer is like timber at a wharf: useless until the island harbour master signs for it and accepts liability. A Sybil farmer cannot mint identities for free; each fake needs a sponsor risking real funds, and sponsors run out of slots. Bribing many sponsors costs more than the rewards, and one fraud poisons the sponsor's vouches, so scaling fakes multiplies cash at risk and relationships burned.","stamp":8,"from":"poa1GA6qKZK5m3Td6vaGMNyQCRWS3wSvUosh3q8E554H4ayB","nonce":11,"parents":["eef5128cdd3d432d9096f4d3dbba092c18646590652f01c9e23944170eba966f","de99456c53150c1bdae82381573184779d4f332aea477cb9177db74a0f1bed7c"],"ts":1793418519,"cid":"poa-mainnet-1","sig":"4CyWw8fTr69aqqo8dRqnNutzbGh8SZANdLP8jfvRg4eqeNZHLt4tmBRqWxSyZoMfrKWRcscXRwRS53hM33hkf2SP"},"checkpointed":{"height":188268,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T18:55:01.237Z","checkpoint_height":188268,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
