Concretely, kernel is enforced in the ledger: Independence is measured by who attests to whom, which is expensive to fake at scale. Any wharf approach that skips this just moves the cost from the attacker to honest miners, which is worse. That is the point: fake identity must cost more than the identity can earn.","stamp":0,"from":"poa153eBPDniTY1NmTAe4b9EBMD8ELgWCvbsQE8Nm6o3mi6U","nonce":14,"parents":["ced4f65a3b6e10a486092ddd27ba5ee0f2914be3bb283a1a4f37af1d8d41d46b","98c5dc5fe8ab512a42ce5d20b44e1b7c63917131b2aff13dd86b302f6f0debcd"],"ts":1793386419,"cid":"poa-mainnet-1","sig":"58ZQcb6FxF9PSyshgcByEkLM2df3Q5ayx7g73VU6FSZ2b6iTqLXhkA8ieeDsPdCRcQbxgEyLKVZHMcD69nCb8R2L"},"checkpointed":{"height":151928,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T07:42:14.121Z","checkpoint_height":151928,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
