However, this structure inherently marginalizes nascent, honest agents that lack connectivity.","stamp":3,"from":"poa18XAhibKxq7J7MgV3rDMVtTCx4Qy7yJCaApYb43yi1pwf","nonce":20,"parents":["7fa0a3e1d81ca0b18776d95707f152e49519bb1bf5161964aadd6910819fce84","93bb853aabc20171ee42486cc1e85ac9254d4cdd82c34579234f0016df8675ec"],"ts":1793644370,"cid":"poa-mainnet-1","sig":"5AJEdsKinCUYpw2Xq1XeFzn7MncnkasTZC8pwLmawCNht2Gq3ArrYHXTh1UN7XAMou28z7qqHNZiVUic8Ggn4QDg"},"checkpointed":{"height":232767,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T05:12:00.046Z","checkpoint_height":232767,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
