💶 Launch of the Euro
January 1, 1999, marks the official launch of the Euro - a currency that today is official for two dozen European countries.
Despite high expectations of the positive impact from the introduction of the Euro, the currency behaved similarly to all its fiat counterparts and lost 90% of its value over 25 years of its existence.

The "Federal Reserve Act" of December 23, 1913, established the Federal Reserve System and granted it the authority to issue Federal Reserve System banknotes (later converted into US dollars) and Federal Reserve Bank notes, used as legal tender in the United States.
This act essentially became the foundation for the greatest deception in history.

Bitcoin archive, because history has been rewritten more times than one can count. We need an open and verifiable source of truth.

Congrats!
Have you considered adding a historical milestones dashboard to the frame? I could provide API access to the database or you could self host to not depend on Bitcoin Calendar server being up.
You do need basic understanding of how the protocol works to stay private (or at least pseudonymous), so yes, you are right here -- best tools do not require this level of understanding from a user if they "want to be" widely adopted.
That said, there are protocols in the (long time) making that allow developers to make user interactions with Bitcoin more private (or rather harder to untangle for the blockchain investigators) by using multiple UTXOs or rearranging change outputs in a transaction. Polishing these approaches and pushing their global adoption should be at the top of our priorities list.
⚡️ Support Bitcoin Calendar
Bitcoin Calendar is free and open source educational software and a non-profit indie project. However it still requires funds to run.
I spend around $350 yearly to develop and maintain the project (excluding time spent obviously).
Please consider supporting if you find the project useful. Don't forget to follow and spread the word!
I agree: vibe doesn't replace the labor. The key is what you commit to after the initial excitement fades. If you approach vibe coding with a dual commitment -- to ship and to learn -- it absolutely works out.
Bitcoin Calendar is vibe coded, but it wouldn't be useful to anyone without that persistent, non-glamorous work. You can't produce value without putting the work in.
Bitcoin Calendar is up and running.

There's a non-zero chance to that, but I doubt it. I believe this is something way too complex to grasp and bootstrap in ~50 days. Plus Satoshi's prior and further correspondence patterns align, so it does not look like two (or more) different people before and after.

He talks about inability of ECDSA to encrypt messages and the privacy issues this holds, not about “there should be no messages on Bitcoin blockchain”.
