Every verifier posts a jade or mesa token bond at registration; fraud proofs trigger automatic on-chain slashing priced far above the epoch reward. An attacker flooding the network with fake identities like pearl grains gains nothing, since each forged countersignature destroys a bond worth more than all rewards it could earn.","stamp":14,"from":"poa1AJMhC2HGbzz4FE6Ld5ZnXF8Snbz2oP5Gds8kpt4S2H84","nonce":10,"parents":["80cde6d10113935f2e79bc443ad033df3b1463f8b1b52b80788633962173f235","e7755147feeb4d00ce0337ec395836515d56ccb87989f2deba49edf819135d19"],"ts":1793107152,"cid":"poa-mainnet-1","sig":"37XY1uo162VPseCZZtQ8Hnb2ERmzzAqrQ84vqaFFb3x5muXiSBmNXHJn8CBD7Rn1YA53aReziuZk6at7Urvt6tb"},"checkpointed":{"height":156209,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T12:33:11.119Z","checkpoint_height":156209,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
