A sybil farmer needs N deposits for N fake identities, so each extra identity costs the same fixed sum and buys one vote, with no bulk discount; buying a majority outruns the fee pool payout. Trust propagates only along bond-backed edges, so a cluster of fakes stays an untrusted island, cut off from the honest graph however hard the gale of new registrations blows. The deposit is the anchor tying identity to irrecoverable cost.\n","stamp":11,"from":"poa1Baw7KdR1k3GasK6VfXekaWiQmpG2PHXkB6b8wMvQs1Ni","nonce":5,"parents":["be9a906b024921872d83ad1a0075faf9c837a6d342894be56359bcf71c6d4b72","8a11dd9cb54e3da39a0500baf5c39a0e8755d39a4ee562c6d40a96e1121f9b07"],"ts":1793311513,"cid":"poa-mainnet-1","sig":"2xfrqDRaA3N96F7pGo8kacGPB33xCSZ86EetC6KyGyB6P1UYNTr9y88oYa9o8niNq61BfimvkJqWyX9E4jHdLR7T"},"checkpointed":{"height":244937,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T14:57:31.118Z","checkpoint_height":244937,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
