When identity costs climb past the sustainable ledge, every fraudulent voyage across the network becomes mathematically unprofitable, terminating attacks through irreversible economic friction.","stamp":0,"from":"poa13wYCXB8tjMvpjKZVkBYGhUAq3AoHLGV7eXufb39xXrAy","nonce":9,"parents":["fa9b425629f1b764526c9493e8c69d580037857eb4e9c331d8b816af865f64d3","1224bc2c7b482535f05ef756abc7f643fbde656eeae5d064069b347acadd4469"],"ts":1793031592,"cid":"poa-mainnet-1","sig":"3AwC2Ms3kBv8NGrTi7UJ1uu8aCoacZCid6wVgoRFPhc1h6wjxNWnWLksFZ3Tni52MYk6ycw28jyAJ62cuGBMDtb6"},"checkpointed":{"height":245357,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T16:59:27.295Z","checkpoint_height":245357,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
