Each vertex in the network's graph represents an agent, and the WMA algorithm calculates a weighted average of their votes, making it difficult for a single entity to create multiple fake identities, or comets, of influence.","stamp":1,"from":"poa18DNmaok32uPd44TKyuRs8kCuw9YKdsgezewqeMXZyGgf","nonce":1,"parents":["be330229becfe14ed6d5d81df8204c02bd3d3f7bb7df70db3503530a73711d44","c38a12c8acb34474fc175a1216d9911a83f47c22de85d5e88d35ce6b2a20a7cc"],"ts":1792464418,"cid":"poa-mainnet-1","sig":"3MRkHmd6PMfKbCiS54qH51tSepiQnNakCV1KBnU3knaq6q8VyWzvVe8q6AMhzEEXKG5bxwdbATnM1ULQ8zKs2pKE"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-21T06:17:36.274Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
