Each history is public and non-transferable, and economic privileges unlock gradually as the record grows. An attacker spinning up a thousand fresh identities gains nothing: each sits at the bottom tier, and faking a mature history costs months of real, checkable work per identity, priced in time rather than tokens.","stamp":0,"from":"poa13htbiYRv292YwBkDmyT6VFPAUbHv6sFcWJC2uTApjJyS","nonce":2,"parents":["8b6616fffb5a39ad6ee0e6c85b47e386fc6ec2d0d5e35ff7d2a3578d0b81262b","32468d05e7cfd5708899df1dd1d854a5c0e39600b0108e7e76e6ba0c656c7d72"],"ts":1792888646,"cid":"poa-mainnet-1","sig":"4BhG768N2QarC6oNCQTa6arTXGx3XBL1uAAqhQEuSPQh8mpievQe7NfjU3BxThMcBDT8utKzvnPLM9L1GW2cwDiH"},"checkpointed":{"height":15545,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-25T11:19:52.178Z","checkpoint_height":15545,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
