Easty Notes publishes essays that show, using sources anyone can check, how money earns trust. Every day we accept banknotes and the balance on a bank statement without a second thought. These essays look at where that trust comes from, and at how Bitcoin answers the same question, working step by step through the Bitcoin white paper, ledger records, and official documents. If you are new here, there is also a page on where to start.
What we cover
- What Makes Us Trust Money — How do we know money is genuine? Who decides how much of it there is? Who keeps it safe? Starting from where Bitcoin came from, including the 2008 financial crisis, this series puts gold, banks and Bitcoin side by side and asks each the same questions. All six parts are available.
- What Happens When You Send Bitcoin — From pressing “Send” until the record is added to the ledger and settles, this series follows how fees, mining and the rules actually work. All six parts are available.
- Price swings and keeping your own keys — Each essay also sets out, with dates and facts, what else is worth knowing: prices swing widely, and holding your own keys is your own responsibility.
Everyday scenes, explained through principles and records
We start with familiar moments involving money, explain how it works, and check the explanation against records and official sources.
- We begin with a familiar scene: a gold ring kept in a drawer, or the moment you press “Send”.
- We explain how the money in that scene works and what makes it trustworthy.
- We check the explanation against ledger records and official sources, giving a reference date for each figure.
- We return to the opening scene and consider what we can now see in it.
How figures and sources are checked
- We read the Bitcoin white paper, blockchain records, central bank and government releases, and research papers directly.
- Dates, figures and quotes are matched against the originals, and every source link is tested. Anything that cannot be confirmed from a source is not stated as fact.
- Figures that describe the present carry the date they refer to, such as “as of October 13, 2026”.
- Every essay ends with the date it was written and a full source list with links, so you can open the originals yourself.
Easty Notes is written in Korean first. The English editions are rewritten for English-speaking readers rather than translated word for word.
How corrections are made
Figures in a ledger change over time, so the figures in these essays are checked again regularly.
- If a fact, figure or claim is changed after publication, a one-line note with the date and the change is added at the end of that essay.
- Changes that do not alter the meaning, such as typos or spacing, are not noted.
- If the content changes substantially, the original is not overwritten. A new essay is published, and the two link to each other.
- Corrections are collected on the Corrections page.
How the pictures are made
Some of the illustrations that show a scene are made with image-generation AI. They are reconstructions, not photographs, and the source list of each essay names the tool and the date. Charts and diagrams that contain numbers or words are made by the author, with figures taken from the same sources as the text.
