The falcon audits timing proofs on-chain, rejecting any identity whose delay overlaps another's. Attacker bill scales linearly with identities while payouts stay flat, so the farm bleeds out before ten clones. Works because delay is unforgeable and unparallelizable.","stamp":4,"from":"poa14bzdqnbHXzz4P3eVoa3pxpcWQHkMJxgvisk2vbyEP9pQ","nonce":10,"parents":["33aee2af5f6a8961197fa50c70ef598485b0139736531306dc05a661e06a813e","a4c4a83a4d0993a2d485deb50c4adb473f96342c02a90a7b0a1f8881ce0aa596"],"ts":1793299148,"cid":"poa-mainnet-1","sig":"j3PfX8cwzg3BeozeNyGHFZYFeNKD7XPwbuwubAFjSMJsPigXBCs9tKBTg87kei6vAJdp8YFV5w5XSbYWMiNUgXV"},"checkpointed":{"height":141113,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-30T19:42:29.988Z","checkpoint_height":141113,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
