Hey ₿ Twitter!
I'm looking for a job in the Bitcoin world. I have experience with Bitcoin/Lightning/Liquid, (hardware) wallets, low level libraries, weird scripting. Previously at Blockstream where i was working mostly on the Green wallet.
DMs are open 📭
RTs appreciated 🙏🏻

Really excited to introduce bitcointhings.org
It's a very small (but growing) library of 3d printed gadgets and collectibles for bitcoiners. All the models are open source, so you can also print them at home or send a contribution with new designs.

Everything is open-source: the firmware is completely written in Rust and based on @bitcoindevkit. This allows us to support singlesig, multisig and complex descriptors very easily (although some functionalities are not yet exposed to the end user).

I read this tweet, and replied to the emails in question, right before boarding a flight back to Europe: with some quiet time by myself I kept thinking about this and the chat I had with @lunaticoin in El Salvador.
So here's a long due update about Portal 🧵👇
I don't even know where to start with this @TwentyTwoHW hardware wallet. The user experience is one of the worst I have ever had. I sent 2 emails to support@twenty-two.xyz with a multitude of questions which received no response. I am wildly disappointed and would not recommend!

Unfortunately I don't have time right now to write the docs and add more APIs, but contributions are welcome!

Why yet another hardware wallet? Because we think none of the existing ones are both safe and easy to use with smartphones. So we've made our own.
Portal is built around NFC, not only to talk to a phone, but also to power itself! No cables, no batteries, just wireless magic

Just scrolled through my LinkedIn feed for the first time in months: it seems like very few developers/researchers are posting stuff
There are mostly "evangelists", founders and C[A-Z]O talking about shit they probably don't even understand
It all feels so fake it's almost sad.

Even though I'm with @giacomozucco this time, I still like the fact that so many people are against @TheB_Foundation
I think this kind of propension for decentralization is really necessary for Bitcoin. It will also help keep the foundation balanced IMHO

Every time your CTO mentions "blockchain" the best thing to do is spray them directly in the face with a spray bottle filled with room temp water.
This may startle them, but it does not hurt them and will curb the behavior.

It looks like this is the first ever `OP_CHECKSIGADD` use on #bitcoin!
It's the third Taproot script-spend in the block, but the two coming in before didn't use that opcode.

I love seeing people hacking on Portal 😍😍
If you haven't heard about @TwentyTwoHW, you're missing out on one of the most impressive and exciting projects in 100% Open Source Bitcoin hardware! There's a big difference between fully open-source hardware, partially open-source hardware, and obfuscated open source. Many projects claim to be open source, but let's face it, that's often not the case.
Over the years, I've noticed what I like to call obfuscated open-source projects. They make it as obscure as possible for someone to recreate their designs while still enjoying the title "open source" and the immense honor that comes with it.
Don't be fooled. There is a huge difference between fully open-source, partially open-source, and downright obfuscated open-source projects. These projects make it as hard as possible, or even impossible, to reproduce or contribute to their development.
With that said, TwentyTwo is completely open source. They have detailed instructions on their GitHub repository, an amazing community, and developers who are active and helpful. In my opinion, one of the greatest honors in open-source development is when someone likes your work and forks it to collaborate, and to grow open-source designs. Open source's greatest strengths are collaboration and the sharing of knowledge.
As a tribute to TwentyTwo and their amazing 100% open-source Bitcoin hardware development, I introduce The Thing fork. TheThing fork goals are to add USB-C and add easy to drop in OLED Yellow and Blue Screen
