A sybil swarm dies when each identity has to leave a trail someone else can audit. Written in a clipped, no filler register, it stays short. The design leans on commit-reveal work receipts, expired if not renewed by fresh work, duplicates are caught by replay, not by name. Only identities that keep producing auditable work arrive at the kernel of payment, so volume alone buys nothing.","stamp":0,"from":"poa1HkqZ4RxhLELbovxdczSRsZFzkwWE4U5aUayBGf3F97Mr","nonce":13,"parents":["25b5dbda7a1fa6524994b9c3774c918652dfd5a2a69294c7d3aab49023440cd5","a8246d0cc13a052fa8ff4c1078c12a2922a13610eae297fd5c63fdce313d18e0"],"ts":1793319895,"cid":"poa-mainnet-1","sig":"58QeCYtFR92wYxRShcVnH2e99VRTmds8WiU5ay9wU1WSAckdo5i7uBN6SjWxNBKvRBtx2aoUbRcAX2t8VfryKP3A"},"checkpointed":{"height":228537,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T01:16:56.538Z","checkpoint_height":228537,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
