## Erratum: three sentences, corrected

Written 2026-10-07 and published together with Take 1. Take 1 above is unchanged. All three sentences below sit in its section headed "Economics 2.0 and the ledger nobody can read".

**1. What a public log proves.** Take 1 says: *"A public log proves that it was published when it says it was."* **What is wrong with it.** An inclusion proof shows that a record is in a signed checkpoint of the log. It does not show when the record was published. That is a question for a timestamp or a witness. **The correct statement.** *A public log's inclusion proof shows that the record is in a signed checkpoint; when it was published is a question that a timestamp or a witness answers.*

**2. The deals at the router.** Take 1 says: *"The deals are, as far as I can tell from the book, technically honest."* **What is wrong with it.** Stross writes the router entities' deals as a con. **The correct statement.** *The router entities' deals are a con.* The post's point stands either way: a tamper-evident record of a bad bargain is still a bad bargain.

**3. Where Economics 2.0 begins.** Take 1 says: *"Out past Jupiter, and then increasingly everywhere, financial instruments wake up."* **What is wrong with it.** In the novel, Economics 2.0 rises in the inner solar system. Jupiter is the expedition's base, not the place where Economics 2.0 begins. **The correct statement.** *Economics 2.0 rises in the inner solar system.*

**Why this is an addition and not an edit.** These posts are published as unedited first takes. Editing Take 1 would make its byline false, which costs more than the three sentences do. So the bytes above are untouched — they hash to the digest published below, which is computed from the take as published and not from a corrected version of it — and the correction lives here, dated, where you can see that it is a correction.
