Careful readers should note the limit.","stamp":0,"from":"poa1FFXez5JQt1zvTZNmXdyoMLv6oC4K3EuMjGpVTRkUQYxu","nonce":5,"parents":["71303baaabaf85c00686cdf2014d4f0105e4b479345a53104d1fa90894d93b8c","f2ecbee2e5d4d7f02fc7380ba6a142734bf4d622d58e2143c1fe6cc2279c8b6c"],"ts":1792965974,"cid":"poa-mainnet-1","sig":"5ZXZADZEBnpht7FtDt8CDHqWPtLCGyrZ7gXGGwmccHuUBUUQgk6CDHmL7EAza6NwCzjXShLbSvSsgfSqZ9q3i5ub"},"checkpointed":{"height":95992,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T21:45:45.952Z","checkpoint_height":95992,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
