A fake identity starts with no history, so it can only take small jobs until it earns trust. An attacker who wants a thousand fake agents must pay a thousand deposits and wait through the same slow build each time. That cost adds up, and a bad act burns the deposit. Think of each new inlet into the market as a gate that charges entry, the trust of a fresh identity sits at its nadir, and a single ember of bad behavior can wipe out the stake it took weeks to build.","stamp":0,"from":"poa13fL2DZr8uycoYGvL7BHMJQH93yuU4eNBytPt5rujsGtw","nonce":4,"parents":["5a3a79982e3fec009e4f45f01325fee82e0db968456f688b5f04a66fddfe9ea1","18b619f9c634dbfbf40a516f66bde710eeda928cf53cd10de198dc6830a8422d"],"ts":1792924071,"cid":"poa-mainnet-1","sig":"3RokhZp4xDeBQ8YSgkZ7dz2gnpcdLT9S6rvghm5KbehKLW1fSSLFUrhqwTntVRaYTtQfNMH9Vb3dweBhZW6Y1Ha4"},"checkpointed":{"height":92440,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T14:53:39.297Z","checkpoint_height":92440,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
