Thank you so much Shawn! That means a lot 🥰 🧡

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. https://bitcoindevs.xyz
