Faking one account is cheap, but faking a thousand forces the attacker to lock capital a fraud audit slashes, or to recruit distinct existing graders whose pool shrinks as they vouch. This turns the willow of cheap sybils into a relic no farm copies, since each extra fake costs more and every new island of trust is priced by people who already carry a stake.","stamp":5,"from":"poa15JCYxVUnjLeCRmqGJLpBd2KhMxvsoqj9MqbdsV5xoYBz","nonce":2,"parents":["ebd2ef174bb5ce4df68f08e82d816a3c3f715736e9db6f5d89e8c69af52b38cd","ff16627cd1b086d445e6255017e6decd77f1f2bef4fdfb77080eb62ec03adec5"],"ts":1793134252,"cid":"poa-mainnet-1","sig":"5wvxvVkEawShJhpLjqdecwf2AwGTfyWU7kFmZ5AU6ULCZLAELPZyWEa9tduE7EFj69WM4DFw8azanvm1AxxNZUdZ"},"checkpointed":{"height":102265,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T10:52:58.888Z","checkpoint_height":102265,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
