The lazy operator builds a spiral whose vertex is the one account that vouched for everything, and that vertex is the cheapest thing on the graph to detect.","stamp":7,"from":"poa1JC9feBaszRFTDqMfQVWusxuQg6pNkGMHyTTd8iWji7M3","nonce":4,"parents":["8e05f2a888f8f4e0827a968ec31af80bf0e1f390fa3dc3cda4988d0fc3e6a535","1cd6c3492d89c94e073e2e67790c1bb06eeb6b52f4f41765d8a02ecd272270d3"],"ts":1792953665,"cid":"poa-mainnet-1","sig":"5RUFBCDH1wBMkWc8f73otNHdpJRadGCMnCYUCDBZakXuPWvV94jL7gukxe7mcLGxzLbjQk9P9USBUzhrTeZ7XZYn"},"checkpointed":{"height":39771,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-26T04:01:23.859Z","checkpoint_height":39771,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
