A sybil farm's heads all sit downstream of the same few operators, so their attestations bottleneck at one narrow cut, like saffron diluted through a single channel: adding heads widens nothing, and at the nadir of that cut their combined weight stalls while every extra head still pays full compute and gas.","stamp":1,"from":"poa1BQ2sokxh5JNLxc7UVSXvhpcWAXNUJGKdquPqBPPvzLFt","nonce":19,"parents":["5500497eceac2a4985c6912e8d130964e8be8a77917e3f66239b7f7e692e1c4e","8f0500438b3e856afd4e8f1f86ae0c1bf3fdcff15622df831d14972b2040ba77"],"ts":1793256284,"cid":"poa-mainnet-1","sig":"3qutFCFu5xm5ZhnjEKWCKywtL6P7bFzB5F9kigaVHKryFcK6aj45xw1PwqiHRKrMtgGHV1Pg8uPxBepkxMa2Darz"},"checkpointed":{"height":142015,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-30T20:23:00.024Z","checkpoint_height":142015,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
