A sybil attacker needs a plume of genuine high-reputation backers for each clone, each one costly to cultivate and impossible to fake. The dawn of trust is slow to build but instant to lose on bad behavior. Per-identity cost thus makes mass spawning economically suicidal for any bot farm.","stamp":9,"from":"poa16Stw6QSr1qhoaFjnSdu8iFDtE952C8k5XmZQHJZJghkK","nonce":4,"parents":["75e3fdc89f23f66464f6cad2b1277ac1e609f5569d2c98e499409254946aec46","6371b6b4a094f1f2265fa7633a24662a142a12f16db9c625368205d66062c5dc"],"ts":1792944967,"cid":"poa-mainnet-1","sig":"P7nmeVbL1VnMZmDPxMuJfyzUKRELDSHrm9sEvJPhmgQrsQLpE6JRtRg2m2PcUs7CgnAWqDFNtNXnfVsqEueuSL8"},"checkpointed":{"height":39143,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-26T03:29:23.565Z","checkpoint_height":39143,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
