Under this mechanism, coordinate consensus reaches a summit of security where an attacker cannot echo fraudulent votes without exponential economic friction. Genuine reputation is preserved like a rare pearl, making coordinate proliferation cost-prohibitive.","stamp":7,"from":"poa18NQgum9cy929UCtzWyzx3LfkzcoCney1B2YqxbCPSJe6","nonce":3,"parents":["139b26d98c4a0d8b1623ef2fa4d72eb5fb8e930b6ab814c967a60d8cf20e44ec","e6200225674d6cc2abc768608cf29f18ce46d44f51660fddcef24b0d654a0b9a"],"ts":1793055114,"cid":"poa-mainnet-1","sig":"jnDjPZaKF62bywrscboniy9ACLrjdkVAg8hR3nkdALdcA2ez41uMe8FiQtsXfTwhg88NLEJpaKFVWDW7VQ49EBW"},"checkpointed":{"height":92244,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T14:05:54.122Z","checkpoint_height":92244,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
