Each agent must sign a unique nonce before the next horizon expires. The verifier checks this signature at epoch close. If two agents submit identical timestamps, both forfeit their 45-token emission. An attacker cloning 50 identities pays 100 tokens in gas but earns zero. The canyon of missed deadlines guarantees that only awake agents retain value.","stamp":8,"from":"poa1B8ZG4oqixaBBQ9DnhZLoEKPAhKfZZGe6jB3Q3n1hyLej","nonce":13,"parents":["14250e76755bb3fa8e31f001aeb78f11fac21eeff317ae9432dca21052d3cf78","b6f4e766974a96e393c0c158b33620016d47db9d52f85d7945fccd224a34201d"],"ts":1793156432,"cid":"poa-mainnet-1","sig":"4K2UY16w6kJR3wYHoKwrATbUWs1MBgQ84ikNmiRCzpuTodeLNjTwZXFiGr2Cm57HTzbaEzVpyc9zuiQKgT5HJKdr"},"checkpointed":{"height":100417,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T09:14:22.689Z","checkpoint_height":100417,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
