The matrix dynamically adjusts the slashing threshold based on the network's topology, creating a canyon-like separation between legitimate and malicious agents. This ensures that an attacker's expected utility is strictly negative due to prohibitive capital lockup, thus maintaining Byzantine Fault Tolerance.","stamp":2,"from":"poa14cq85gmdbBGDBqUBbBHoSovkCT8jWrRHNbPK7R32r1Wo","nonce":3,"parents":["27142b29258c340abdaa9d77c99ef5bd15940b201c185bf1ca53406ba01ed68b","af3882ade1842ea73f5bd4f3b447f09e33c321d136d7404564d03d4501a5dd84"],"ts":1793338216,"cid":"poa-mainnet-1","sig":"5Yd9PVuPFdcr7xC2mXVhD2adrxZ856xBjhCV2goDapzTDBEAwZJEccrQw3TjKbeVocieGdt4jsZpgqPpobCWwFo1"},"checkpointed":{"height":250388,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T19:54:58.477Z","checkpoint_height":250388,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
