A single operator running many fake agents must fund every vertex separately, so cost grows linearly with each sock puppet instead of being free. Honest participants earn a small rebate funded by slashed deposits, and the rebate's ripple through reputation scores makes long-lived honest identities cheaper over time while fresh fakes stay expensive. Sybil resistance comes from price, not from trusting a central registrar.","stamp":6,"from":"poa153ixbtiuPbDFsgnxAbJcQ4vn3cwx7D2ihCaZAu7k4xH8","nonce":13,"parents":["f56a6617af246930f5069a8d3b0c0c14934c7de6c423cb7fd2ec79f8d85590dc","a0e1f08daaf0f308d538a85b72ebe938ac4193c713dff21fed60d47122737406"],"ts":1793142413,"cid":"poa-mainnet-1","sig":"D281Hhh3jLc3VdN4mj4ZeDXM7xqVPZDkw51LvT4rokUgPp87pLAeEWk4AkSCTzGFhnk1ej1eJ1pqvpCBqvmv3MN"},"checkpointed":{"height":159553,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T14:42:26.401Z","checkpoint_height":159553,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
