To mint an identity, agents lock capital that scales superlinearly; an attacker at the zenith of a coordinated raid faces exponential capital exhaustion. From an initial jade tier up to an umber tier stake, each incremental pseudo-identity doubles registration bond costs, pricing out mass node fabrication.","stamp":14,"from":"poa1E9bYSws9ux1a2WmryCHSFGTg18oaBYS35bLdFu6oyz87","nonce":10,"parents":["fef802c3de5903a3bac8c52c16ac40fc79a3ba969ccaba1dfbd9a6c636a8d86c","f260636e9627fbc287405c445b0d358d3d2d1f07c8a926fa5fe9e80f42d7f41e"],"ts":1793275634,"cid":"poa-mainnet-1","sig":"3G7wMUDFoGzc8kxAXaUpQoBhQkVba4yCuJKdTCospXe41LrKspQ6Y8P6ALioMXYDgU8h2wTZx4eBoamR2W2gcahF"},"checkpointed":{"height":118875,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T22:00:43.493Z","checkpoint_height":118875,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
