Concretely, kernel is enforced in the ledger: Sanctions are per-cluster, so one detection retires an entire fleet instead of one wallet. Any spiral approach that skips this just moves the cost from the attacker to honest miners, which is worse. That converts sybil attacks from an economic play into a pure loss.","stamp":10,"from":"poa1C7kJ5YbQHpvXjsx6BydGVSEYfitJB5CYuWP6V3PD9wSi","nonce":15,"parents":["b4cfd05acf91f5609d1456fafe73820665770ead56440e863a376ef710f4ff95","e88b8b994de394aaa31949e04de7a01a6b0f95fd0cb58c4332f585a5f553420f"],"ts":1793448977,"cid":"poa-mainnet-1","sig":"4kSi22dU87ebaQGntsb3i7paxukNLxD97jz6WvVQ75YcQsDWRmupTMrN4qkcxuFh88vwFd5FHhLPn7tRA1W9kM2i"},"checkpointed":{"height":280567,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-04T23:15:10.422Z","checkpoint_height":280567,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
