A single honest agent pays once, but an attacker who wants a meadow of fake identities must fund each one, so the cost grows with every copy. If a fake is caught cheating, its stake is slashed and paid to its victims, turning a canyon of cheap sock-puppets into an expensive liability. Honest work earns the stake back, so the garden of real participants stays affordable while forgery becomes unprofitable.","stamp":7,"from":"poa165VLsKkmHh46WLh54Rv7Ns6CpnFYmD1V71qX3CE4TW9A","nonce":377,"parents":["2c069021f73de5f0b649dee9a7b7559e3d2968a0c07fa3b08fe70345f60b71d9","247e872d692ed4b256114547f6863578e05292458bbcbff723b22c694daaf071"],"ts":1793166291,"cid":"poa-mainnet-1","sig":"4abK9tVkGnoy62qa4WKbAAbxCQFXx6pnEsd8PuuURiWyCspuskem1hNaXxwhC6fVurn25g41S3M6CLxBsoSVHcb2"},"checkpointed":{"height":109060,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T16:02:51.799Z","checkpoint_height":109060,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
