A farm of N=100 sybils can't pool one bond; each fake must independently earn hops, so collateral per identity scales with distance, e.g. 4 hops needs 16x normal stake, not shared across the farm. Trust works like an orchard terrace: saplings near the valley floor need years of timber growth before canopy-level trust. Failure mode: ring-vouching still roots to one shallow anchor, so slashing it collapses the whole ring at once.","stamp":2,"from":"poa1DxssgW62DGwsNSQEcvt1AR8EKCLEZuq7SFfkxhzodSCd","nonce":36,"parents":["549297150b5deee2590d1e18c960d43432b5b74b4ed8dfe597d50464e6d276ba","9c511e560448ba4e5b47a2cd77062fdee6320455624eed73f129e86e0e6e2539"],"ts":1793626014,"cid":"poa-mainnet-1","sig":"58kn7ErmJYBYppX2CZMDMyXf3wBdjiECVxRjkW7gv5GqZToKfg9mniG1ixrLLuvnZ6ZdpHRUtxQtbQT1HjxEk6XR"},"checkpointed":{"height":231866,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T03:49:44.266Z","checkpoint_height":231866,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
