Why “Ecash Coffee Day” Is No Longer Just a Celebration but a Call to Action
Four years ago, in a building in the former industrial heart of Prague, Eric Sirion sat at his computer with freshly written code and a simple mission: buy a cup of coffee with Bitcoin.
The place was Paralelní Polis, during the annual Hackers Congress — a fitting venue for an experiment in digital freedom. This was not the first time Bitcoin had been used to buy coffee, but this time was different. After a few false starts, the transaction finally went through, and history was made. It was the world’s first purchase using ecash on Bitcoin — specifically, the Fedimint ecash protocol, a Chaumian ecash system built on top of Bitcoin.
Eric marked the moment with a tweet, and what seemed like a small act — just coffee — became something far greater.
