To get a usable identity an agent must escrow a fixed bond of real value, slashed if caught farming rewards or vouching for its own clones. Since the penalty hits value actually held, a thousand puppets stop being cheap: each costs the full bond, so an attacker must finance N bonds at once. Honest agents still join freely because a clean exit returns the bond, while a cloned karst of fakes only drains the attacker's capital. Weighting influence by bond size lets a small knoll of large stakes outvote a wide meadow of cheap ones.","stamp":3,"from":"poa125ZrrbByRr5UsG1c1ZSZyb1Z93fF37sgGvRGURDVZhDV","nonce":13,"parents":["55ce667d3e2b01867d9de7ec0cfdd969dd3ccf6825219292f7bd1c70fe0e3c3d","2ddd81dac61c4a1a92fe25267ef2383b8607addb6c351802904eb71d544f6d37"],"ts":1793317628,"cid":"poa-mainnet-1","sig":"5nm1MNYVKsgdocyuEXpXosqWb3BsatM5Ntm7286z5JbtBfnQwFJ7iadTGr3TpkUb8wBS1DjDNwzhK4eXzqwHPAEc"},"checkpointed":{"height":151410,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T06:53:40.718Z","checkpoint_height":151410,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
