Thanks to everyone that attended our @HRF Oslo Freedom Forum workshop. We hope you had fun and learned something! While we only had time to cover one project, Canary Bitcoin (http://canarybitcoin.com) by @Andreas. @MouxDesign (@Bitcoin Design ) made her Claude skill file publicly available for all to use 🙌 🔗

This skill file gives you the experience of a senior bitcoin UX designer at your fingertips. Simply upload it to Claude (you don't necessarily need a paid account) and it will ask you a few questions about your app. Then you will be prompted to upload some screenshots and the design review begins! It will walk you through low and high fidelity mock-ups, as well as an exploratory phase where it borrows good design from sample apps. Feel free to tweak the skill file to reference other apps. The possibilities are endless. Big thank you to @HRF for the opportunity to do this. We hope participants can take what they learned and use it to make projects more accessible to activists and other freedom fighters 🚀

Transcripts from the recent @Bitcoin Core Project Dev meeting are now up on Bitcoin Transcripts:

Bitcoin Core Dev Tech 2026 (May)

A collection of technical bitcoin and lightning transcripts

Shoutout to the one and only @schmidty for always making sure these get uploaded 👏

Calling all freedom tech builders! We are seeking volunteers for a live design review at the Oslo Freedom Forum Making Freedom Tech Beautiful workshop. Face it. Freedom tech only matters if people can actually use it. Even the most powerful applications fall short if they feel confusing or too technical. Watch @MouxDesign of @Bitcoin Design and our very own @satsie 🇹🇭 🇱🇹 use AI to apply tried and true UX principles and draw inspiration from award winning design. Participants will leave with a Claude skill that preserves the exact process from the workshop. 𝐌𝐚𝐤𝐞 𝐲𝐨𝐮𝐫 𝐚𝐩𝐩 𝐚𝐬 𝐞𝐦𝐩𝐨𝐰𝐞𝐫𝐢𝐧𝐠 𝐚𝐬 𝐭𝐡𝐞 𝐝𝐞𝐜𝐞𝐧𝐭𝐫𝐚𝐥𝐢𝐳𝐞𝐝, 𝐜𝐞𝐧𝐬𝐨𝐫𝐬𝐡𝐢𝐩 𝐫𝐞𝐬𝐢𝐬𝐭𝐚𝐧𝐭 𝐭𝐞𝐜𝐡𝐧𝐨𝐥𝐨𝐠𝐲 𝐢𝐭 𝐢𝐬 𝐛𝐮𝐢𝐥𝐭 𝐨𝐧. Make it something individuals all over the world can understand, adopt, and rely on. Builders need not be physically present for the workshop. Priority given to projects funded by @HRF.

The pangolin mascot naming contest has a winner... 🎉👋 MEET MERKLE! 👋🎉 The name is a nod to the cryptographer Ralph Merkle who created a number of technologies that are fundamental to bitcoin. He is most famous for co-inventing public key cryptography and creating the Merkle trees we all know and love. Congratulations to @J.T. Woodhouse for submitting the winning entry on nostr. To celebrate, we will be releasing some special content on Merkle trees next month. The runner up was Petunia 🌸 Honorable mentions go to those that submitted the names Scaly, Petey, Pauldron, Ronnie, Pangoshi, Bitsy, Nacho, Toshi, and Leroy. In the coming days we will be reaching out to you so we can send stickers your way! Thanks everyone for your participation! The names you submitted were so good we may have to expand the Merkle family tree to include new friends 😉

HELP! This little pangolin started hanging around our website. It’s been at least a month and it doesn’t look like it’s going away anytime soon. What should we name it? When we launched our new website in December this fellow quickly showed up. Now it needs a name and we want your suggestions! Reply to this thread with your best name and if it is chosen, you will win a BDP swag pack. Stickers will also be sent to honorable mentions 😉 Pangolins are solitary, curious creatures known for their armor-like scales & quiet determination. Like the best open-source contributors, they build, explore, & protect what matters. To us they represent the kind of thoughtful, persistent energy we see in bitcoin devs daily. You have 10 days, until 2/26 to share your best, most clever, and imaginative names. There is no limit to the amount of times you can enter. Let’s see those names!

The ₿OSS Challenge is designed to get you started in a career in open source. Deadline to apply is tomorrow, December 31. Don't overthink it. Apply now and change your life in 2026.

Well, we finally did it. We got a logo for the Bitcoin Dev Project got a logo and a new website to match it. For the last few years you have trusted the Bitcoin Dev Project (BDP) to bring high quality, open-source tools and education to the developer community. Today, as a symbol of our ongoing commitment to this mission, we are proud to reveal a fresh look. 🌿 🌿 🌿 Let’s start with the pangolin in the room Yes, that is a pangolin. Is this unexpected? Yes. Is it intentional? Very much. Pangolins are solitary, curious creatures known for their armour-like scales and quiet determination. Like the best open-source contributors, they build, explore, and protect what matters. To us, they represent the kind of thoughtful, persistent energy we see in the bitcoin dev community every day. 🌿 🌿 🌿 How it began In 2023, BDP was born from a desire to build for the developer ecosystem. We created efficiency boosting tools like Bitcoin Search and ChatBTC. From there, a suite of educational products and even games emerged with things like Decoding Bitcoin and Saving Satoshi. This past year we rounded our offerings out with the Common Application which helps contributors apply for funding. BDP has been lovingly designed to serve the developer community in a way that is approachable and encouraging, yet without compromising the hard work and discipline required of bitcoin development. There is much more to bitcoin tech than what is seen at the surface. That is why we created BDP to be a place where you can grow your technical skills without the noise. Anyone in the world should be able to participate in bitcoin development. If you do the work, BDP is there to help you reach your goals. 🌿 🌿 🌿 A reimagined website You’ve seen the logo but that’s not all. This makeover goes far beyond that. Instead, the BDP website has been completely reimagined to deliver more moments of delight, improved navigation, and easy access to our tools and resources. The new illustrations, icons, and vibrant color palette are all inspired by the pangolin’s natural habitat. With an earthy, nature-inspired theme, the website is warm and inviting, reflecting BDP’s goal of being a welcoming entry point into bitcoin development. Despite all the changes, you’ll still find the things you have come to expect from BDP: learning material, developer tools, and funding guidance. BDP provides new opportunities for you to explore and take meaningful steps toward becoming a bitcoin developer. 🌿 🌿 🌿 Design secrets For more on how the logo and website came to life, check out this blog post by our amazing designer Sanya. https://medium.com/@bitcoindevs/glow-up-95008146d653 🌿 🌿 🌿 From the bottom of our hearts, thank you. We’re deeply passionate about the work we do and grateful for your support. To those that don’t know us: While getting confused with BDK is arguably a good problem to have, we hope you’ll stick around and get to know us. We’re in this for the long haul and would love for you to join in the adventure.
