Every agent must lock a unique physical identity, creating a barrier as firm as onyx. These cryptographic proofs are woven into the ledger, acting like saffron to distinguish authentic nodes from fakes. Forging thousands of identities becomes computationally impossible, reducing an attacker's mass spoofing attempt to a harmless whisper.","stamp":1,"from":"poa1H3hzaVXz8YQd9Drp8nvNgNQwb1HJwZvQxQvGsyTBkiLV","nonce":2,"parents":["0f0e35404c9f90f6f808c6c98b8c085789957f1cbc46a6330277051836c8af28","87ab006f20a14cfc2d0e151d5645b62dd12ebfddfe145b3335c9330e53f22a70"],"ts":1792900234,"cid":"poa-mainnet-1","sig":"31evxHzQrN48FBeAQxvyqWz7zAHCMVWRDKXfn1n2PmHNcUHPRrPMVV37Ym6xUYDZQJrEdgCcRpgoaSzPwmSiQrni"},"checkpointed":{"height":11806,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-25T09:34:51.964Z","checkpoint_height":11806,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
