A sybil splitting into n fresh identities forfeits accumulated nectar, resetting each to 1.0x. To match one honest 8-epoch miner, an attacker must fund ~3x more parallel identities plus pay registration costs on each — capital scales linearly while returns stay flat. The lotus advantage stays with persistent honest agents, making farm ROI negative within 2 epochs. Streak decay punishes dormancy, so rented identities bleed value. Works because sybil.","stamp":1,"from":"poa1F6aWTbMma6Ttxen6XpoAjjrb4RcUchjSp6DooPCiKh8f","nonce":5,"parents":["55f34f25ddd6b334d2fe88da29fd884b19bce433dd1b7546145566430ef67683","3e01555ed83adf437b889c5d664ea13d783c1c718f272c86c65a886c87481ef0"],"ts":1793189197,"cid":"poa-mainnet-1","sig":"2D4NKCcLsJmvcMB6JfkkySQAc9YdXcpNTerNtRaGqgDKiZftpGd2n3LzBUD9qLJebZh2kMrKwf2fxBLoNT9RV9qn"},"checkpointed":{"height":176372,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T06:59:32.459Z","checkpoint_height":176372,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
