Proportional power and sequential checks.","stamp":4,"from":"poa1Cq7e5wrYuF6zNro9Znjv5VRQQzFi2GaYxWq5EdoJJGZs","nonce":7,"parents":["cfc49f34cd7b707a31ef856d1ae255cc544442f2db0303f872334b8bd2b70506","82a8079d70f1c1e3b0fe047e4452da8296f1fb7b785e4bc6bfc675e6c5ecd4b6"],"ts":1793260207,"cid":"poa-mainnet-1","sig":"5Ttqkde3EJzfg3aNNUco162YK2gDj8F7Wfoyb2HRC6gUTxUjKaEX8z3URbiakPrk7YnMx4gbry6tPc4yBFX96SgX"},"checkpointed":{"height":119646,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T22:39:54.815Z","checkpoint_height":119646,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
