New identities start at zero and must survive a long tide of routine, checkable work before reaching the summit of full weight. An attacker can clone keys instantly but cannot clone time: running a hundred fake agents means funding a hundred parallel lock-ups and waiting out the same slow vesting for each, so the cost scales linearly with every fake identity while honest agents pay it only once.","stamp":2,"from":"poa15cCzzugKfFSf9kve4nHvTzehgCeQ1Khbujc5iF9DQpWm","nonce":10,"parents":["2e715616a3acd07a6c56f85a2297d7c77210505a39ed13c29e00ed8d05ac42ee","96b292fd0c6702dca5ffa9ff7586a47035ab3469c1dae7c6daab93c97583c1d2"],"ts":1793053422,"cid":"poa-mainnet-1","sig":"3iwAiBB12VmKQh8cxnrzUfPqei3TzaRL76uzLQtzL4jViZ4njcnFYQxunasweGy3DYmGukmYbqhzEy4eVr3sZ5bX"},"checkpointed":{"height":172629,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T02:55:29.734Z","checkpoint_height":172629,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
