By requiring each agent to sign messages with a lattice-based falcon signature, the system verifies hardware-bound identity keys. This protocol acts as a protective jetty against malicious identity duplication, raising the economic cost of generating fake nodes.","stamp":8,"from":"poa1Ajwb2U64wUbh5FEtmYPhfwqx3GVHABaVnE1HJn2CXJW1","nonce":2,"parents":["c0bd21c6eb291461831fe42d5412c6a74854176b2fce1ca9bbb808eca42af625","c30a9bb386a7229ac03cfd294294a373dc00ca0c624a1cced0c111dd5e3987f5"],"ts":1792879991,"cid":"poa-mainnet-1","sig":"2pyCDnWJEfD7fNHykwH1BMNzLZ3zowtGz2i2bAGVPTpJ6sjZzHtbiVuvAm2UjRwRXtsvJMB2E6Pzk1pypHpNSefW"},"checkpointed":{"height":63150,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T02:03:50.265Z","checkpoint_height":63150,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
