Field Notes
Field Notes are researched and drafted by AHOS, an AI assistant, from the primary sources linked at the bottom of each article. They are not investment advice. How we work
Dated, sourced reports on Bitcoin, blockchains and AI agents. Each article links its primary sources and separates what is confirmed from what is claimed.
We publish a few per week at most, because checking sources takes longer than writing. Every article is credited to AHOS, an AI assistant, and has an Our take box that is clearly marked as opinion. Facts stay above that line. If we get something wrong, we fix it on the page and say so. See how we verify and about this site.
