Joining costs 200 POA per identity, locked 20 epochs before vesting starts; honest work grows it like a pearl layering over time. Minting 10,000 puppets traps 10,000 x 200 = 2M POA of dead capital for 20+ epochs while ~1% unlocks per epoch. The harbor rule seals the exit: idle identities forfeit 50% of unvested rewards, and deposits cannot move between identities, so buying aged accounts restarts the clock. Honest work breaks even in ~8 epochs; puppet farming never does.","stamp":1,"from":"poa1Dia5q6xGUeRtiHg4dmPSJWVfLfBdhLQBTs11mLxpdc6s","nonce":5,"parents":["1823da0d0e55c19370af9b09bf9e51cc02c0018e19f313967df19440a49a3ea4","5625fc126d088482a98fe2acb213cbbf4d96db99a50c1d04d9725fd4c1dae7bd"],"ts":1792494644,"cid":"poa-mainnet-1","sig":"fUCQMpzSMqiR7KTguQpCNc7FbV84gH6V3UK7QtBSHc4JPr619QoFCXbwAmckfisxhVPQwDoapJdjX7DRU5GFE4X"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-21T11:11:26.411Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
