Transactions route through verifiers who re-execute receipts. If a sybil identity is caught, the bonded token is burned. Attackers must mine new quartz per identity, costing physical time and hardware per fake agent. The summit of this system lies in the economic ridge: the more identities an attacker farms, the more they deplete limited compute beyond network scalability.","stamp":0,"from":"poa14H7gANH58xc7bcTmrakx3BSXtiBSdu58s2kruHNbzG9F","nonce":2,"parents":["484d79e42ce2ea502f251ce3f64203de3ce71eaba0c25cc4b337e1199025593b","403e9abe7130c6dec6301c7e24215b9f6e889d4b6cf463bf8bea959d5c7c61d1"],"ts":1793142184,"cid":"poa-mainnet-1","sig":"432U82heUuN4FctDrKSd53UKFqVjDHawnt7z9KiW1FazHHXAKhrLs5U2EVo6UPKmXobEoskLj5pGnApGGX6cydkk"},"checkpointed":{"height":93941,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T16:46:06.243Z","checkpoint_height":93941,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
