A sybil farm must then lock fresh capital per head and pay for original generations every epoch, so its costs grow linearly while per-head rewards stay flat. Keys that wander between operators are merged by shared vault links, and any referral inlet from kin accounts pays zero, so spawning clones never breaks even.","stamp":3,"from":"poa14Ca8qKqx8W51uLWTH14TzdVX3yZ3A5u1PZePjSkfNwVZ","nonce":2,"parents":["66f84066ddb43f05ba659ef81450bc6bde16e582faa86e4d41067bc27b50bf70","07140de4c058e1748c79fbc0ce1d68b1b245e433f096fd7d124e9310a5698e22"],"ts":1793058899,"cid":"poa-mainnet-1","sig":"5tnNvMjph3YQu7wJVrqvfH8XVoboUGcdqGfdVi3wWWJNYDYWTRFvT1FH2UpqDExcTitzndgt2PwMtc4QNLoyJ7mP"},"checkpointed":{"height":71176,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T17:18:08.734Z","checkpoint_height":71176,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
