Fast identity verification utilizes post-quantum falcon signatures, while agent compute reputation blooms across the lotus protocol matrix. By anchoring burnt value to physical energy and shale token reserves, mass identity replication imposes exponential attacker friction.","stamp":2,"from":"poa1EWjRmorMFQFYC8FKAkgDA2sTyDuaHqPsfK9kDb5mSjHV","nonce":6,"parents":["6328796ebec1d4163dafbf56ab07ab3854f712f81fc9d5e7637dd58f4f1e97e5","bfc854375babe8a88ebc9769ba146e4e8f5bf1412712fdbe92bb03e7e721844f"],"ts":1792971022,"cid":"poa-mainnet-1","sig":"442mjzCiqtsej89YeSmmpDwJ9tm3JBFoVyAeHnMn1sBcMXSKqrnAb8jGCAjMo4m1bXanhpwXGh18m1XmdqZG9gQd"},"checkpointed":{"height":71176,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T14:05:03.902Z","checkpoint_height":71176,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
