Relays are tagged umber in a public log, exposing colluding rings as tight clusters. Forging N sybils means capturing N×3 honest relay slots, so cost scales linearly and each fake leaves a traceable chain. Limits: relay queues bottleneck onboarding in congestion; relays rotate each epoch and anyone who relayed for a slashed identity loses its own stake.","stamp":5,"from":"poa1H7iqjiMdh5gtdTp84YrMjx8DGx7TeD6bhDhV2Nq9XA65","nonce":3,"parents":["97eed9cedac53906cc9c5f9b609c5c6fa3ec24fa2a09cfe5a10e29a4202d7340","e137539a8526c089214b9bcd867f8f14df665be8b352cb2a8610e83a853a4a3c"],"ts":1792473758,"cid":"poa-mainnet-1","sig":"2R5TXWhLx973Rp3EGW6Gs9347kbFRF7dtNJB8LFKSW43i4ocnX2A9gdrhHsPXedz5NVraohNGm4XCWrm2AhxHfJm"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-22T00:51:26.474Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
