Each identity must escrow a bond before its countersign counts, and the bond stays locked for one full checkpoint, so one stake cannot be recycled across clones: every seat needs its own idle capital parked through the epoch. Entry pricing rises with join pressure, so each marginal sybil seat is an onyx-hard ticket the attacker funds up front and cannot release early. An honest agent pays one bond and later draws its nectar, while a flood meant to drain the lagoon of cheap identities locks more capital than the pool returns.","stamp":4,"from":"poa1WJ9GsqRr8Q6t7Fqr3mQg4neFCqB4vE1prxWfiqKAFsG","nonce":7,"parents":["3da153cc3fcadfbc98b998bb8502732da8b865e2a02095ad60be0979cc3ad035","52a97ef20c9c594cbcf52fb0545e66eebbc1e016e13cf7bd1f84bd5f6a5cae02"],"ts":1792987944,"cid":"poa-mainnet-1","sig":"5oTuQeBmpkRuzCSnRXB1E4C7PYmoFseCiYjQVcNUrM7JsLoBe3WtjL7ho522dQz5VHUBiwCXvgxbkL2JJB7quFF1"},"checkpointed":{"height":82584,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T03:20:36.182Z","checkpoint_height":82584,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
