A clone farm must grow every separate root because branches cannot be grafted across addresses, so cost scales super-linearly with headcount rather than splitting across clones.","stamp":2,"from":"poa1J7msgdKXCfG3Ai1HXRawAhQ6Htt8ZiDqytqnygLqMq8W","nonce":12,"parents":["37b2c6a37c883e2447f5ba5c8bfcacd1b3254af9b1d69494474fc41f45e559e7","275e026169d1324c7f9984c15528a005446c9789e7d15e3211e6a2859db82ba3"],"ts":1793120176,"cid":"poa-mainnet-1","sig":"Tgzhtd6AoeDbJ45TWdZPJ6NKArRReUHrtZFB8DVPFxyKXLqLhXcbSUM5CuUE4HCtzSb366jX4K7UG8WM4mCyatf"},"checkpointed":{"height":169734,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T00:39:13.309Z","checkpoint_height":169734,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
