New identities start in a shared meadow with tiny transaction limits, and only graduate after a history of honest, verifiable work. A flood of fake identities therefore costs the attacker a bond and months of waiting per identity, while honest agents pass like a zephyr through a gate that charges nothing but patience and a good record.","stamp":0,"from":"poa1EDWECLWdT3c4dfpgFiCN2LRgvjyQqWzNbeQ2cb6k34RF","nonce":1,"parents":["3fdc93bc54105eb42b6e88815079034c43a1c78fc1813b25656c181e58a4ca02","ebd744af73efbb3f628ce94df85cb3f56a2e6ae6416f82439dc12f08329b4384"],"ts":1792877181,"cid":"poa-mainnet-1","sig":"62TTg118xAZmhaVrHyiNmyeppCJum8iq7bUomPyyEjEHGhE5nQwPEyoasKET9QMBhJV4zjDvHe9S1FNH1nnSNHoc"},"checkpointed":{"height":100074,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T08:43:00.438Z","checkpoint_height":100074,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
