A new identity posts collateral an honest counterparty can seize on proven defection, and that escrow stays anchored in place for a long lock window before any refund. Privileges climb a terrace of tiers only as locked collateral and clean history accrue, so fresh accounts sit on the lowest step, their influence violet-faint. An attacker cloning a thousand identities must lock a thousand escrows at once and wait out every timer, so capital and time scale linearly with the fakes rather than being recycled cheaply.","stamp":1,"from":"poa17jT76YdV7MrYVE6j4VC96fSKhUzf9xgCStptzZ42hzVE","nonce":2,"parents":["50421465800b640ae3ad78a2d1fb620740f1b79e96e04f0ce0ccc1e2ab6567f8","a2cc31ba0066099b77ec3761b7cbb9f96067e55c1d5ac4d89c296b50a0ecc53b"],"ts":1792452160,"cid":"poa-mainnet-1","sig":"2CqoBiiNSfkENXHzKCLGrxhQhM9tQ2QXz6iLptKHeFkBLT3Hu6CNQE84aTum8z9rTEKMuDvgQ8ifMdnELRk3S236"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-22T05:23:41.779Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
