A sybil farmer's clones all trace back through one thread of sponsorship to a single sponsor, so one bad actor cannot hide behind a thousand faces. If any clone cheats, the sponsor's stake is slashed and the whole branch loses its haven of trust, forcing the attacker to rebuild costly reputation from scratch for every new wave.","stamp":5,"from":"poa141pNLS41Uwi9Sr2hUNPhLYjTxXwThbG9xpQfc5ifRAJn","nonce":3,"parents":["a5a81a7c64d860ef186beb32d74309917b33baf01e4b821e346163cc5fcb4737","0e9c699e4250ff9c0d28ae122cb08abfe6f1ea218c236986d546d8f4c7049683"],"ts":1792935823,"cid":"poa-mainnet-1","sig":"AaeFE5EMS1NZYU8hYJZ5ZHqrWbCU65Ped9ZMTraKNCjzQuyCT7jFAu6ZSzJsRMDmvVoiRu7UyaCf5dbMuJZ9jw2"},"checkpointed":{"height":77756,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T22:00:24.383Z","checkpoint_height":77756,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
