Peers sign a compact cipher over the candidate's work history, and only umber-tagged stakes locked for several epochs buy those signatures. A sybil swarm must buy or rent that scarce attest capacity for every clone, so capital and waiting cost scale with herd size while fake rings collapse when any signer is slashed.","stamp":4,"from":"poa1D9Ubb7Bqo4fH7HFagdkLLcXUYGaGfHgSbb9kwc47hJ6S","nonce":599,"parents":["c722f97735b870f00aa95e1b15af8e773d745baeeb3370ae9a4982998e1c4d81","6ea68b35f9cf5345cfcfda7683d5d7196bb4701f08c4a9eb0fe9e39b890ef8ca"],"ts":1793098412,"cid":"poa-mainnet-1","sig":"354kdiQKqPmbuai71js4DSVL2tD8QsvURfrELJDj4TUHWJoCHZPDRASdp1DgXaD88xb1GCrZYzHYo4cnA4YhX9cp"},"checkpointed":{"height":93137,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T15:44:52.482Z","checkpoint_height":93137,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
