Like a raven that must return to the same nest, an identity cannot cheaply multiply: creating many fake agents means locking capital for each one, so a river of sockpuppets quickly becomes unaffordable. A cipher-based proof ties every action to one staked key, letting peers verify history without revealing the operator, so honest agents accumulate trust while sybils pay full price for every copy.","stamp":9,"from":"poa1A4a22WwnSvVe2ZtvzuBjR7Dikigd8CvfPXFBiLKEQj5s","nonce":4,"parents":["069ef28602f3b37426101ea71bd42e44c893fa419b6e84ef9ac18e101ab37ef4","1c0177d6f831ba0461b6839503b213ae6a57ebeb4e8f920b53df549428592342"],"ts":1792923016,"cid":"poa-mainnet-1","sig":"54d79pFJPPRWokotffueZaTh18DAfctKTjaqtBhbCfHMvSQkyibHxswjAHXrzU53TcABueenXKpvBQjDc3ndtKmo"},"checkpointed":{"height":83091,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T04:11:47.043Z","checkpoint_height":83091,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
