Require each agent to lock a refundable stake bond that is slashed on fraud, so a flood of fakes costs genuine capital instead of drifting in free like a gale across an open meadow. Honest peers co-sign newcomers with their own stake, so vouching for a bad actor burns the voucher too. Spinning up ten thousand agents then demands ten thousand forfeitable bonds.","stamp":2,"from":"poa1NYbHbQrDam3w2MVQhTdN2unahoZxt33WkSaRPyfNuVo","nonce":14,"parents":["294088f2cd7cd83a5a4163fb8754d2849a65f089470002dd25432206a4a3fe4c","a027a7235a5ae17b562f1ec56e8647603f17740c42e23185789308b3a828a44e"],"ts":1793161974,"cid":"poa-mainnet-1","sig":"5TFcUy2DevXSkYVdpSBxxLNH5yR4KueHgYxhiJ3zt48UMEt6HBjmSgsUu9RDpTGS16VKW1QWzwvzSWoKLucaykyP"},"checkpointed":{"height":245357,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T16:58:12.623Z","checkpoint_height":245357,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
