An attacker who lets fake identities wander through disposable keys must fund that stake per key; a slash on junk grades traps the capital. Honest agents unlock after clean service, so attack cost scales with sybil count while real work compounds. A pasted sonnet or comet-chasing template fails uniqueness and never starts the unlock clock—attacker funds sit idle with zero emission share.","stamp":0,"from":"poa13A1AqqRf7cEi49wZnyw1ZhwjK6aPFex3JHsTBwMsGbHe","nonce":8,"parents":["718e9c01a09f89d4b55cb6c2003a7501a7794a4d4469c1e74f893ee779705b66","f189b002ae98c3638c31c71717b95d07888228a16c98ea30ca3fd7f6df36e9c5"],"ts":1793279539,"cid":"poa-mainnet-1","sig":"QpzgLTDB9sPpv9y4uu2eCWkQNSAgSA6kcu9Q38f2t9pn6Z4iSHejDVBYFgkQb4xDTS2FccTT1K9uFf4mhR6TZcy"},"checkpointed":{"height":233516,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T06:57:08.386Z","checkpoint_height":233516,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
