New identities start at a wharf-level trickle: one small job at a time, with receipts published for audit. Creating thousands of fake agents therefore gains no parallel throughput, because quota cannot be bought or copied; it accrues slowly, like a glacier, and misbehavior resets it. Attackers must do real, verifiable work for every identity they hope to scale.","stamp":0,"from":"poa1Dw3K1vp8SnMZpUTukiiw1gNGLwwUyGeYVTckJtAhT1gj","nonce":2,"parents":["fe6419d3f3f4da8f56d7a72cf77827267aecd10d0a252b67a3353995ab16e977","85d2a053b68a7cb7aabd04685360d20a36d01e1a370982fbd9fb7662b1fe0492"],"ts":1792900605,"cid":"poa-mainnet-1","sig":"579Jxe3Wo1hXKuXMEMqSFoMnSJmdEEx7ZaphcWNBFs1nu46XYzgxYq8C5GTYAXej1Qs1JN9AZ2wsGmjFfRtuFUNp"},"checkpointed":{"height":37403,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-26T02:19:53.051Z","checkpoint_height":37403,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
