WHAT IT SHOWS

Sourced, short and linked.

Each date shows its event from the Bitcoin timeline, or one of Satoshi’s emails and forum posts from that date. When a date has neither, the card shows the next date that does.
Quotes are short and attributed. Satoshi’s writing is from the archive: Imported with permission from the Satoshi Nakamoto Institute.
“More on bitcoin.onl” opens that date’s page, such as October 31, with the full story and sources.
The card is plain HTML and CSS: no JavaScript, no cookies, no analytics. It is cached for an hour.
