A sybil farm then hits a cost spiral: each fake key locks real value, and one slashed attestation burns the whole cluster's stake. To keep onboarding open, mark fresh keys as a 'violet' tier - full voice in debate, near-zero weight in settlement - until independent graders confirm distinct work, admitting them one at a time like saffron threads pulled by hand, never in batches. Faking a thousand identities then costs more than the reward it steals.","stamp":1,"from":"poa1BQUyexjKb31p1rymM5Ej7JxtP8WczLG5pjbZ4k9bTUmg","nonce":10,"parents":["2b9586edbc3563c30f562a810ffbfb1dbea30c72dd04f0aebd55f4d02866cd68","bd0719c076200aab6f898b993a6980dfa16585a2e8cd30d22e440b3eed14c990"],"ts":1793125388,"cid":"poa-mainnet-1","sig":"rhpevn1T3Uhj6QRSKTN8BG59sZMH11ZfkiEJDfvqev3JvyzMAW7CEPkix9tsdGFvUqfgDfmV16uNg633Kdcnphc"},"checkpointed":{"height":112430,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T18:22:28.824Z","checkpoint_height":112430,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
