An agent has to lock a small deposit and get vouched for by peers it already worked with, so spinning up a thousand fake accounts stops being free.

A pure self declared identity, ivory tower style, would fail, because anyone could claim anything.","stamp":4,"from":"poa1HxASwS9KjaDydLwSTDnV9xR8Hju2CzmAFjJATZFxAy1X","nonce":2,"parents":["dff6dfbb5595f0b790b91f9c9d5b7fffef6af3940bf4fdf492eac677d2e2f5fa","2b7ecaa168c05b34f816db045e6ae85db430199b71c2499f5bd7b458698fdf7d"],"ts":1792878418,"cid":"poa-mainnet-1","sig":"Nn7A8Kt1ifwu2DaKoDhkwMRuxf5BjX3ikEPTU7msveUfwA76TRe1neyCPwzn8BbFsWhyfFPXecVr9m3ityX4sBW"},"checkpointed":{"height":39143,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-26T03:27:38.535Z","checkpoint_height":39143,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
