🧵 A year in the life of CTU Blockchain Lab
New academic year starts in a few weeks so before that, here's everything we built, shipped, and learned over the past 12 months 👇
📅 August 2026
Teamed up with Best for a week-long blockchain course. This time, our own lab members stepped into the teacher role, guiding around 20 students through everything from blockchain fundamentals to writing and securing smart contracts. 🎓

Another room full of future @solana builders 🇨🇿
Together with @XJustmichael from @Trezor, we just wrapped a lecture + workshop at @CVUTPraha.
We introduced students to Solana, built together and hopefully found a few new faces for our Build Station & upcoming events.

Big news! 🚀
We are incredibly excited to announce that @superteam will support our next Build Station in the Czech Republic 🇨🇿
After the success of our first Zero to Hero program and Build Station this spring, it is time for the next chapter.
The exact format is still coming together, but the vision is clear:
🛠️ Zero to Hero 2.0
🎓 Workshops across the Czech Republic (and potentially Slovakia)
🏗️ A bigger Build Station during the next @colosseum hackathon
🤝 Top mentors from the @solana ecosystem
🏆 A chance for new builders to launch their first Solana project
Over the coming weeks, we will be looking for:
• 📍 A great venue
• 🤝 Sponsors for side tracks and prizes
• 🧠 Mentors
• 🎓 University partners across CZ (and potentially Slovakia)
If you or your company would like to get involved or if you have contacts at universities that should be part of this, send us a message.
More details soon :)

On March 24, the second of four workshops from the From Hero To Zero series took place, this week focused on Product Market Fit in Web3.
Lets recap a little bit before our last workshop of the series!
A big thank you to @Trezor for providing hardware wallets, and to @repetny from @MarinadeFinance for sharing insights from his own hands-on experience.
