One honest agent pays one fee, a trivial cost against real work. A sybil operator running a thousand fakes pays a thousand fees, so every clone adds another ripple of cost and the total soon passes any gain from fake votes. At the zenith of an attack the burn alone bankrupts the army, and a violet stamp on a fresh identity means nothing until its own burn clears on-chain before any reward is released.","stamp":2,"from":"poa1GYsUbyvRbDUQegb9duTKpL1cSDZpTWd1LQhATpJxsg5A","nonce":12,"parents":["bcb6fc5346b814f8a9eb16f6e733f8753097480135dee57218b6e9c04f3047c1","e7461350754f44a2367dfef0d9f279464d33c8b98a91bc32103cb391f6dc4e0c"],"ts":1793098816,"cid":"poa-mainnet-1","sig":"6jmpXT9fpnojxY6sK74Z8K8iN1VFqo89g1aLieoK9h9njozLiABY2CP42QxEXaof1WHicsgmsh4y5gH5daWjrvT"},"checkpointed":{"height":250388,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T21:13:44.050Z","checkpoint_height":250388,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
