On a journey to Bitcoin OSS contributor

[Sammy @Smtech02]

Just wrapped up Week 4 of the @btrust_builders CLI journey and what a ride it’s been!

From expanding transactions to diving into the Bitcoin scripts, this actually pushed my limits ... but I fought through and got my raw transactions to pass!

This is what we tackled:

Week 3 in the CLI Pathways program @btrust_builders was all about Cracking Multisig Transactions & PSBTs

While working on the exercises, I faced some challenges and after some solid debugging, I finally got everything to work and ..

Here are the things I was able to accomplish:

Watch Party Wednesday was a huge success!⚡

Today, we watched an insightful panel from the @OsloFF 2026 featuring @ihate1999 - @btrustteam, @obi - @fedibtc, @AnaiseKanimba - @AfriBitInst, and @waithiraah - @tando_me, discussing Bitcoin adoption in practice across Africa.

Some key takeaways:
📌Real adoption happens on the ground by listening to users and understanding local needs.

📌Communities need practical tools, not just theories.

📌People want to experience Bitcoin firsthand before committing to saving or spending it.

📌Education, community, and real-world utility remain the foundation of sustainable Bitcoin adoption.

The discussion reinforced a powerful message: Bitcoin adoption in Africa is not just about technology, it's about empowering people with tools that solve real problems.

Thanks to everyone who joined the conversation and shared their insights.

See you next Wednesday for another Bitcoin rabbit hole!⚡

"not everyone has the luxury of an extra 10,000 hours to study bitcoin. Most people just need simple tools to move value." –@waithiraah

Talking about the practical use case of bitcoin for everyday people, beyond just the hardcore bitcoiners.

Does the market decide bitcoin's future? @lukedewolf weighs in at @btcplusplus economics edition in Vienna last week

[Hack4freedom @hack4_freedom]

Day 7 of #Hack4Freedom Lagos with @a_Iyanu_ from @bitdesigners

The real barrier to Bitcoin adoption? Not technology. Design.

Key takeaways:
🔹 4 core user fears: seed phrases, addresses, fees, transaction confusion
🔹 5 design principles: plain language, protective defaults, progressive disclosure, recovery, transparency
🔹 4 recovery methods: emergency kit, social recovery, multi-sig, cloud backup – all have trade-offs

Human-centric design isn't nice to have. It's safety. It's adoption. It's trust. ⚡🧡

"SatQuest" by Stephanie Ademuyiwa.

SatQuest is a mobile-first game that teaches Bitcoin and Lightning through 26 levels of puzzles and word hunts, built with a Lagos/Nigerian lens.

Players learn Bitcoin basics, earn real sats as they complete levels, and can start without a bank account. This is Bitcoin education as gameplay.

Bitcoin Designers Meetup, in collaboration with @bitdesigners is coming to Nairobi , here's what it looks like. 🇰🇪⚡

A space built for UI/UX and product designers, male and female, who believe Bitcoin's future is human as much as it is technical. And it needs designers to help shape it.

You can look forward to:

-Bitcoin & Open Source Talks:where design meets decentralisation
-Workshops: hands-on and practical
-Opportunities: real ones, for designers ready to step in

Never touched a Bitcoin product? Doesn't matter. Show up curious.
