An attacker-heavy roster weakens the draw, and unselected members cannot vote.","stamp":3,"from":"poa15DZCmDhuNFdQsLZ6kZEoqof72DgRTbxJXinFcg8Qun5q","nonce":19,"parents":["9c0a8fe97b59423875677706dc7000850ea66da74f61da36676d5aff7c56a467","2d882d01f9b96e534b3e61d99e9d7e7c181f27d7090c559dead339fd202a1e7a"],"ts":1793281603,"cid":"poa-mainnet-1","sig":"443BjGJaNAjuJmTCRC5cPQaGQVD4yGjzt394xZ1xhGTVhWJdMHt2xcQKc9UQKnpvT4UtxX6DCZ15GyLxr4MpZgyr"},"checkpointed":{"height":150524,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T05:56:58.117Z","checkpoint_height":150524,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
