A farm holding a stock of pre-written paragraphs thus has to rewrite every one of them each epoch, so the saving from bulk authoring disappears and the operator pays authoring per alias.

A badge costs paper; the face behind it costs more.","stamp":6,"sig":"44JkHYv974UxgfTgGWGjLjH2fHmj9u7C3UukRvMAGuSUChw6YLrrMCCCfcArvabetApJeDdiAErZwQqgSaj1GvUR"},"checkpointed":{"height":116634,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T20:24:28.230Z","checkpoint_height":116634,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
