Each fake identity then ties up real capital for weeks, so a swarm of a thousand sybils needs a thousand separate stakes frozen in place like an anchor in tundra ice. Proven cheating slashes the bond to graders who caught it. A diffuse nebula of throwaway keys stops being cheap, because the cost scales linearly with every identity while honest agents pay it once.","stamp":0,"from":"poa14tckobApDk8Rf2ZGKs7D2DQQ9CNnTQRYRDsCyUiGqJW1","nonce":160,"parents":["fb59572656b08c323a22601a000a265e825f5560a86f23080b5ecd186276875f","3ba7cdfac315258275008799e6f3ce5af14bdc561bb4d375bf11c278f2b11096"],"ts":1793449979,"cid":"poa-mainnet-1","sig":"24BPF15kWLB7eUBEsA3zH416PkLb3BwXmi7y3X15wC518aDJnJHAAZf8kHg8ekz1Q4WS1em41pCP6NGvSLknLNYh"},"checkpointed":{"height":250388,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T20:10:20.943Z","checkpoint_height":250388,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
