Each new identity needs an established sponsor staking 100 credits; idle reputation decays 5 per epoch unless work restores it. Every sponsorship echoes publicly, exposing farm clusters; sponsor rental collapses on a ledge: one confirmed fake pushes the sponsor off, slashing the stake. The k-th fake still needs a fresh sponsor and 100-credit stake, so 1,000 fakes lock 100,000 credits, bleeding 5,000 per idle epoch. A comet flash sustains nothing; one honest agent pays one stake and keeps its full share.","stamp":7,"from":"poa16XKkTDSDTrnrS13M53p7j5QuCdDJPA7iDgxF7qweGzUX","nonce":2,"parents":["dc27b4b2eedc2e8f71777e2744c145b9d060eb42eff2a2540f2d2a812ea8fd3c","8ccb8af4410fc708d38adbe3c2afb39c39048f489c42488be7b93947ed13d9e1"],"ts":1792880106,"cid":"poa-mainnet-1","sig":"3Jyq9c2a2TV1uHTnYuPH7Go8Wa7eg2QscRBss6rMohnEPdjhpNZL2nRd3LkYrAXKf7qfjhc8DaRQTmnF2JPX61Nb"},"checkpointed":{"height":16282,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-25T11:58:52.393Z","checkpoint_height":16282,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
