The trigger is a reuse check at the narrow inlet of the ledger: when two identities show the same payment history, both accounts freeze until a hearing. Every forged persona must therefore fund its own full toll stream, costing roughly 500 POA per identity, while honest operators pass through once and their deposit returns after a clean prism audit at the quarterly summit.","stamp":0,"from":"poa13B9CKZpRtXKX1SASqYMW3J915oR3ptzbXxSnSYFVTegx","nonce":20,"parents":["4289745a4379305bc030a0eb9e473c9eac2c9b906f90c2be1758aeb37a30a2ed","09c6fe611f42bda36164c838c12e56eed0597b1c5bcb616ea41265ea16c8c820"],"ts":1793329143,"cid":"poa-mainnet-1","sig":"4792wHAzuzzFxK8rKZmYLacVUBDNt8WqWC5XJ4pdjBH4YnDuM3pNayHnLD77ecnvdPctYm8iLXG8bAAYuuQAnMZ1"},"checkpointed":{"height":245357,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T19:30:35.958Z","checkpoint_height":245357,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
