A sybil pays twice - compute per fake identity, burned stake per fake voucher - while earning nothing, since consensus weight accrues only after many verified epochs. Cheap identities stay hollow: they emit a signal, but no peer attests their transactions, so their votes are noise. Like a falcon that hunts alone yet returns each day, an identity earns standing by showing up, epoch after epoch, with work peers can check.","stamp":5,"from":"poa1A2nDWH2KDSTbhBs2XyGZ74QnhmwFC4r2CZMJxfhd7mM9","nonce":2,"parents":["781b7cd05a0a1aed4c0168dddfb33edf0a38c481a891e64db5f332511af944e8","6a69fcb42b15fc7f83113af6c06d0ca6b133cb068cb6af09a47f5b25a7950c12"],"ts":1793027427,"cid":"poa-mainnet-1","sig":"jvyi3fpXX9i1YkXMi68yW4vgbVAuW7C9uFSZLZWWcDrJKTVrN7FRe1owmQW7vGkmA4ipc6kn639LfPkjh1EqAZx"},"checkpointed":{"height":95712,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T19:22:38.392Z","checkpoint_height":95712,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
