Top Students, Top Mentors and Top Platform @the_buidl
Rust for Bitcoin 2.0: From Learning to Contribution ⚡ Several weeks of technical sessions, two weeks of capstone development and open-source contributions wave. One Demo Day. And 22 merged pull requests. Delivered in partnership with @btrustteam, Rust for Bitcoin 2.0 equipped developers with practical experience in Bitcoin development, from transaction construction and HD wallets to Bitcoin Core, Rust libraries, and Lightning Network workflows. The Results Participants have recorded 22 merged PRs, with several more open, across Bitcoin related projects including BDK, rust-payjoin, Floresta, rust-miniscript, rust-bitcoin, Bitcoin Core, and Lightning related repositories. Capstone and Demo Day The two week capstone challenged participants to apply their skills, move from concepts to implementation, and develop projects using what they had learned. Demo Day brought this work into focus, giving participants the opportunity to showcase their projects and demonstrate their progress. Many thanks to @btrustteam for their continued support in growing a strong pipeline of Bitcoin developers and open-source contributors, advancing the mission to decentralize Bitcoin development across Africa and the global ecosystem. Congratulations to all participants, and special thanks to our tutors and mentors, @200OKDeveloper, @0xGideonBature, @Akshola00, @damola21mm, and @Johnsdanlami, for making this journey possible. The learning continues through building. The contributions continue through open source. #TheBuidlGrid #BitcoinDevelopment #RustforBitcoin

Our co-founder took three years to find his way into Bitcoin full-time. At Bitshala, we’re working to make that path clearer for the next generation of Indian developers. No shortcuts, just a better-supported path to building a career in Bitcoin. Watch @RajarshiMaitra's session from @BTCPrague below 👇
Most people think the only way to make money in Bitcoin is to buy it. @RajarshiMaitra quit his fiat job to work on Bitcoin full time. Now @bitshala_org trains Indian developers to do the same. It took him three years alone. Here's how long he says it takes now.

Bitcoin has places to be. Literally. Tapnob eSIMs are now available for Bitcoiners. Pay with sats and stay connected across 100+ countries. But connectivity is just one part of the bigger picture. Tapnob brings digital money closer to everyday life, connecting Bitcoin, stablecoins, and local currencies to the things people actually need. More options. More utilities. More possibilities. One platform. More ways to put your money to use.
We are beginning to roll out eSIMs on Tapnob. Get connected in 100+ countries without searching for a local SIM when you arrive. Travelling, working remotely, studying abroad, or just moving between countries- your connection can travel with you. Bitcoin and stablecoins will be supported with more payment methods coming soon. Tapnob is becoming more useful for how you actually live, travel, and spend globally. Coming in the next few days. 🌍 Get early access her: tapnob.com/esims

Thank you for working on Bitcoin. Seriously. Fiat money and the system of control they've built around it is terrifying and it will never loosen its grip around our necks. If we don't save ourselves, noone will. Thank you for helping.

Today in Chandigarh, just one person showed up for our Bitcoin meetup. We sat down, had a conversation, and started with a simple question: What is money? We went deep into how to build a solid foundation, exchanged some read's like The Internet of Money and Broken Money to understand further. Every conversation counts when it comes to orange-pilling the world! 📚🚀

Just routed my first successful Lightning Network payment using dual LND nodes running locally on Bitcoin Regtest! Getting the ZMQ configurations and custom TLS handshakes playing nice inside WSL was a fun puzzle, but the transaction went thrux instantly. App Dev mode: ON
We are docker using everything. And it must work😅🙌🏾🤝
