Back to work 😁🙌

I just found the best reason for this

server to keep running Bitcoin.

gave me these NFC cards last year as a donation to us now they will be a tool for kids to learn and use Bitcoin as money in a sovereign community 🙏

Kids deserve fun 🧡

Yesterday at

, we finished Chapter 2 of Programming Bitcoin.

Understanding elliptic curves and going over the exercises in the book was a lot of fun!

The new supplementary videos are on the way and will cover all the exercises from the book's GitHub.

I value self custody more than you think, so I started teaching kids how to use the official COLDCARD Wallet simulator.

For some reasons I needed a web version to keep teaching, so I created this as a tool to simplify the lecture.

Self custody matter.

Preparing Sovereign Bitcoin lessons 🙌

We just wrapped the

Ch1 programming Bitcoin book!

From Finite fields to Fermat's little Theorem (in the last lecture

students tested their knowledge with a very fun Game)

Wake up Neo (Bitcoiners understand this)

Thanks to Konsensus Network, Leo and the authors we donated books to Berlin Bitcoin Center 🙏🧡

Teaching Bitcoin 🙏

https://chirilicas.com/

Today, I had the pleasure of leading a technical session at

Bitcoin Center to teach:

✔️ Openclaw + Ollama + Lightning Network ⚡

AI Agents and Nostr: I demonstrated how I configured my own AI Agent to send payments using the Nostr protocol.

I’m incredibly excited to see how the intersection of Local AI, Bitcoin, and Nostr is opening new doors for true decentralization.

We officially do not have permission to teach Bitcoin to children in public schools in El Salvador.

But I didn't want to miss the opportunity to thank you all for your support over these past three years. Thank you.

Building on Nostr 🇸🇻

Today marks our last node setup lecture in public schools in 🇸🇻

It’s been an incredible journey: 5 nodes in year one, 45 in year two, and 20 so far

We leave behind +2,500 students with real Bitcoin tech skills. A chapter ends, but the impact remains.
