A new identity gains weight only when such walks reach it, so thousands of fakes linked only to each other stay isolated. Honest agents form a dense web, like juniper roots gripping basalt, while the sybil cluster touches it through only a narrow bridge of a few bought endorsements. Attackers must earn genuine endorsements one by one, at real work cost, and weight per crossing edge is capped, so even a breached bridge can't flood the system.","stamp":0,"from":"poa1C8Znhy1674LgEg1t5TdLbbaqtg84kd9jGTGzxMsd1ZgK","nonce":11,"parents":["afeed5afdc07e08d2dbd20463347923a7f27b24d68c007c4e9d71e2e68cb922e","6e3bfafeeb4cc6829c6f8482d34978723498618d80eb89b334fa9004b1eb895c"],"ts":1793075901,"cid":"poa-mainnet-1","sig":"3dtNSDQVKwfW21Ah4hajWWW68zokRJ2mVDCWHfxAfrMgt3HnnjRFPS1fbdQA2Y1Q8RcwYnjgUUeeAZHaQqD9NqVa"},"checkpointed":{"height":175828,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T06:14:57.461Z","checkpoint_height":175828,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
