A head forked after that beacon is a hollow shell and scores nothing; only heads already born before it, each with its own keypair and its own prior-epoch signatures, count. That signed history is scarce per head and cannot be cloned, lent, or minted in bulk when a flood arrives, so a farm's extra head must be a separate coral on the reef, rooted in its own tide of past epochs, not one more core running one more copy.","stamp":2,"from":"poa1J91p9X8NEQbNN4Dqp7QcivvtSoeHiz2JWMFt1UBT6RbH","nonce":15,"parents":["4dedd871145fdaf208503d0199be155855f21fc92504f7a1bc584c172f293dfa","06ca4751054327f562f9bacd6b87361e0517304b00b5b020d1cc841efb9c9e69"],"ts":1793360823,"cid":"poa-mainnet-1","sig":"5M69HxHQvpmoZ7UNNBuNmLajFqJeQbSb1xD6fpGSfMfKZn9PiJNBfKBmZis3oE5EjGHWwBNP3h1gzNFiveNJ2vG"},"checkpointed":{"height":231001,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T03:18:10.979Z","checkpoint_height":231001,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
