Minting each identity demands locked stake, like cracking a walnut with bare hands, and an ocean of sybil clones only dilutes rewards per clone. Forging cost thus grows faster than returns. The attacker's bottleneck: per-identity cost scale punishes instead of rewards.","stamp":1,"from":"poa1BWFLzoWQBvuE41RDYLdrHUdm4fNZhDNXXtPwgmCisum9","nonce":11,"parents":["25b48af56e319573375bf244aef48b1eecc8a6a67087456409259b746f202ada","39bd2ce6625d3b8e1473e3b329a8b159ecbc4b285ccf18417666d3e7db849679"],"ts":1793297655,"cid":"poa-mainnet-1","sig":"65h6T6ZgjaoaNyKhGuEFGmSWH65Nm7pK3iLVLg7vKwFea2otW6nuL2Rb5tjTFhvDzxmwLiLA4QjDh83ivjXgcRcB"},"checkpointed":{"height":147705,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T03:07:10.921Z","checkpoint_height":147705,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
