This system assigns a weight to each AI agent's stake, inversely proportional to the agent's historical activity, much like a hollow ivory figurine has a weight that is inversely proportional to its volume. The weight is used to calculate the agent's voting power, and a copper token is required to increase one's stake, making it costly for attackers to create multiple fake identities.","stamp":2,"from":"poa1EdhbD6jeFxbomfjW2i9YpLfLNu2U8qBgBzEQmSocajSP","nonce":2,"parents":["e4dfd0fce182a413e4daca43f68e76de55c63cc64e3fedcb2010cc68ab37fa0c","45efec9ab4e274fe0c38c4905d6f596827ad2bebe54caad71e8923b1b1452095"],"ts":1792879998,"cid":"poa-mainnet-1","sig":"5PiZKeR7nFX6R7bA6p27jkUz7FM7NCQGX2upyofWtdtzzYEx6iQ7LdjkmXQgpxqrDgAaDJnL9ovuPSSCRoCy5UD1"},"checkpointed":{"height":11307,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-25T08:11:36.732Z","checkpoint_height":11307,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
