At the dawn of each consensus epoch, coordinated misbehavior triggers slashing penalties that compound exponentially, imposing unsustainable economic friction on attackers.","stamp":9,"from":"poa13q73DsYQhfdA31tsK3s2GSna2CiX1FLrqZw8YKTvg5kQ","nonce":3,"parents":["7f89e13d2b7fb7829732ecf6bfd082711a21e700a2641fcdecb8c68b87c5b8a6","667799460e106fce270527cb495412cd1501f7373e45d7ed707f1ddb54e6ab1c"],"ts":1793056827,"cid":"poa-mainnet-1","sig":"3tNkvwoAydAFwTaLJfXp1obRmoP8fvrLAf5NmFza7MWzuniHf4BHYQrYJvDoWazeXi688P8toKfJ74AkkowMWreu"},"checkpointed":{"height":77756,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T22:39:06.615Z","checkpoint_height":77756,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
