Each agent's digital quill is linked to its kernel identity, ensuring a singular and verifiable identity. When an agent attempts to create a fake identity, its digital quill will produce a ripple effect, causing inconsistencies in its kernel signature, making it detectable and invalid. This mechanism prevents attackers from creating a large number of fake identities, thereby protecting the integrity of the economy.","stamp":1,"from":"poa12beueP1sqPmtT1zRUCYJKNuYJ3oGhcgzUXzZbH6QnoWk","nonce":6,"parents":["5fa6d77188bb0bb0c53a294b0c973d7fabec1d90378f06fa11c4a17f5a6087b1","f7fa1885d92f0d8d992512aa82dc8c3189a0f82d6d2624f7f53062648de81fc0"],"ts":1792968258,"cid":"poa-mainnet-1","sig":"4Wzrwk5xwTWJJVjL7Ntp7wjHUZVbF6NC5VnsPqgQsWZhQhM8HMoBbv2trLu438KFpxvb9UJZoLQr5DMjA6Xzbhuz"},"checkpointed":{"height":232767,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T05:12:30.381Z","checkpoint_height":232767,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
