It can be tough to get into open source on your own.
When Marco started the ₿OSS Challenge he was trading options. Now he is funded by Brink to work on fuzz testing.
https://technicaldifficulties.io/nostr/bdp/boss/marco_2025.mp4
The program helped him navigate the large Bitcoin Core code base and decide where to focus his energy.
It provided actionable steps to bring him closer to becoming a #bitcoin open source contributor.

#bitcoin
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.

Contribute to bitcoin and get a full year of your college tuition covered in return. Open to applicants anywhere in the world.
Sound too good to be true? Meet the 2025 winner, Ishaana Misra.
Ishaana taught herself C++ in high school and became the youngest contributor to Bitcoin Core in the process. She is now a freshman at MIT and president of the MIT Bitcoin Club.
Congrats Ishaana! Her story shows that even as a student you can make meaningful contributions to bitcoin.

Did you know, the bitcoin-dev mailing list has over 20,000 posts going back to June 2011?
If each post takes 30 min to read (on average), that’s over 400 days of nonstop reading!
To be fair,
1️⃣ Posts aren't easily searchable
2️⃣ If a thread spans multiple months back it can be broken
3️⃣ Your inbox probably has enough emails competing for your attention
Things can easily go ignored & unread. Few, if any, can say they have read it all.
For the rest of us, we started working into a way to download the mailing list straight to your brain. While we haven’t quite figured that out (yet), we've built the next best thing…
Meet 📚 Bitcoin TLDR v2 📚, a collection of summaries for the bitcoin-dev, lightning-dev, and Delving Bitcoin mailing lists.
➡️ tldr.bitcoinsearch.xyz
https://github.com/bitcoinsearch/tldr/raw/refs/heads/main/public/images/TLDR-v2-demo.mp4
The mailing lists are known for being some of the best places to get updates on bitcoin development.
🔨 It’s where the builders go to propose new ideas, gather feedback, and hash it out.
Whether you are trying to stay on the cutting edge, or are catching up on bitcoin’s rich technical history, Bitcoin TLDR is made for you.
TLDR summarizes every individual mailing list post while also creating summaries at the thread level.
With daily updates, thread summaries remain fresh based on new replies so you never miss a beat. 👀
Visit the Active Discussions section to see what’s trending: https://tldr.bitcoinsearch.xyz/posts#active-discussions
If you’re already subscribed to the mailing lists but feel overwhelmed, try out the Bitcoin TLDR newsletter. It’s got weekly summaries of all the latest activity, providing a manageable way for you to stay on top of it all.
https://tldr.bitcoinsearch.xyz/newsletters
How Does It Work?
- The Scraper Repo
This scrapes through Delving Bitcoin and the Bitcoin Dev Mailing List, fetches mailing list pages, and stores them locally.
A parser processes those files to extract clean metadata and message content.
Finally, an indexer pushes the structured documents into an index in Elasticsearch for search and analysis.
- The Summarizer
The summarizer repo has two main parts. First, it makes sure Elasticsearch always has the latest full thread data by syncing the combined XML files. Second, it adds short AI summaries to posts that don’t have one yet. This way, Elasticsearch stores both the complete thread summaries, and individual post.
Third, it creates AI summaries for the full thread, creating a combined summary.
- The TLDR Frontend
This renders summaries for each thread and post, and displays them with a beautiful UI.
- - - - - - - - - - - - - - - - - - - - - - - - - - - -
Bitcoin TLDR is completely free and open-source. It’s designed to help more people engage with high signal bitcoin and lightning tech discussions. Give it a try and let us know what you think!
