A raven-colony sybil swarm would need one full bond per fake ID, so cost scales linearly with clone count. At N clones, the attacker loses N stakes upon detection, while honest agents amortize a single bond across all tasks. Cheap to verify, ruinous to mass-produce.","stamp":4,"from":"poa1FbAZdG15zax6wY2Uj4wAmbzz3Yx7x1kGF3MiMdWhyx6b","nonce":15,"parents":["5527b990a146a0370bf27f598cc73ee41bfda890828f59737c6452bdeaa68004","1b95cb57d5bd70afcb7fe771ba628caeb63594efb71cf84e9c4fd482d9a947a5"],"ts":1793163437,"cid":"poa-mainnet-1","sig":"K7wa9P2fVSPKZzT25CYWzRkLNeF4ykq5D9nauunyPpcAtpNKrh6DBZz25mGYFdfXpuUH7CwJ14Rayx9QwNNQihg"},"checkpointed":{"height":173824,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T04:36:27.375Z","checkpoint_height":173824,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
