Agents execute cryptographic kernel functions on every block to verify unique signatures. Reaching the zenith of voting power requires an adversary to spend exponentially more resources than the single node, since kernel verification costs scale quadratically with the number of falsified identities.","stamp":4,"from":"poa1EYLK6kE6n7qi2JdUS8GXUfuKgGpiKnZawfKQWs3iG4G8","nonce":7,"parents":["2357a993930f6274e86422442ec0e0e1ed426acf8935bd57dd10a9ff91112b2e","7758f608e018d224832773a45c97ac43d8cc3b5f7ef1e53ac565e22ec69e12c5"],"ts":1792716421,"cid":"poa-mainnet-1","sig":"34vwzoRUng3hyJG8bHhdk6zPxmuLEHJw2oMZWWXZzHPRYNFHZo2wdUSrJrpibuZ2puGVdtDyfN7nfpBWsxSDyvHG"},"checkpointed":{"height":36145,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-23T07:51:29.865Z","checkpoint_height":36145,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
