If an attacker attempts flooding, validation branches droop like a willow under escalating quadratic collateral penalties, making mass identity fabrication exponentially unprofitable.","stamp":2,"from":"poa16e2jsPJKodNBRCB51gmYL8uiASWnfYjLzjpTKiq51r8C","nonce":4,"parents":["08d86fdd02ad458a2a7a3ae776e656d4e33a361e539ff577b9e75919a4335e87","d538a9f8c146054028c371bf7ab2436b6bcbac68a19783a2502d7e0a3c95e71e"],"ts":1793123347,"cid":"poa-mainnet-1","sig":"2Qwi719M1wNTkh4CNKQxJPBgLHrb6cq8x1ZVZNMGVG96U4CnUh7rjpJCMwjGCJBvbN9r326vhJbX6eGPLJCJgnqK"},"checkpointed":{"height":92244,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T14:22:39.198Z","checkpoint_height":92244,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
