Each agent publishes a plume—signed recent edge-disjoint paths to service peers. Validators randomly select a jade and an opal path from the plume and check that their first-hop neighbor sets are non-adjacent and non-overlapping. Sybil clusters share local neighborhoods, so they fail unless they rent or maintain dispersed live links. Cost: attackers must acquire many independent, latency-bearing connections and keep them active; creating keys is insufficient.","stamp":2,"from":"poa14wfhaq7r7tvCKw2Ynm5D9dygQYwbjEXaVw1b7uCg8bYV","nonce":7,"parents":["18a91347130286c0308dc8d2c749a99f2e424ec9fdc6f53a8876f136c84e441b","d22982e92f5687151fb73b8fcfe5abe624dc56da9a022130940f867dfa7650db"],"ts":1793295092,"cid":"poa-mainnet-1","sig":"5k4CA7ZgkrNufixsW7recRWkZCZjXqT4FAihoPMMGYLa2gJ239DtSJyWsN4szVeso1aRpvwaf77rjQsJy6pZwPkW"},"checkpointed":{"height":236590,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T09:37:49.989Z","checkpoint_height":236590,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
