entropy = good more entropy = more secure keys But can we imagine what 40 bits of entropy looks like, and how does that compare to 256 bits?

𝐖𝐡𝐨 𝐩𝐚𝐲𝐬 𝐛𝐢𝐭𝐜𝐨𝐢𝐧 𝐝𝐞𝐯𝐞𝐥𝐨𝐩𝐞𝐫𝐬? The code for #bitcoin is completely free and open-source (#FOSS). Anyone can view or build on it. There is no CEO of bitcoin, no benevolent dictator, no foundation. It's open-source taken to the extreme.

Interested in what #bitcoin could look like in a post #quantum world? As the community continues to research an optimal upgrade path, check out this comparison of post-quantum signature families: - Hash-Based - Lattice - Code Based - Isogeny

Passed 13 years a couple weeks ago and just passed 80,000 rep. Too bad hardly anyone asks on Stack Exchange anymore, in the age of text-generating clankers. End of an era.

Thanks to everyone that attended our @hrf.org Oslo Freedom Forum workshop. We hope you had fun and learned something! While we only had time to cover one project (Canary Bitcoin), Mo (Bitcoin Design Community) made her Claude skill file publicly available for all 🙌 github.com/mouxdesign/V...

Calling all freedom tech builders! We are seeking volunteers for a live design review @ @oslofreedomforum.com Making Freedom Tech Beautiful workshop. Freedom tech only matters if people can actually use it. Even the most powerful applications fall short if they feel confusing or too technical.

Happy #Bitcoin Pizza Day! 🍕 On this day in 2010 Laszlo Hanyecz traded 10,000 bitcoins for 2 pizzas! It may seem wild to think about now but had it not been for people like him that were willing to use btc as a medium of exchange we may not be able to transact with bitcoin the way we can today.

OSS development could be fun if people saw you as a person instead of as free infrastructure to take for granted

mental health is also about maintaining boundaries the baseline for OSS contribution is "scratch your own itch", you don't need to spend time on features or fixing bugs that don't affect you, or people you actually care about. no one is entitled to support just because you make the code available

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.

🧰 Too much bitcoin tech knowledge is trapped in videos and podcasts If only there was an easy way to unearth those insights and gems… 🤔 We wondered that too, so we redesigned Bitcoin Transcripts! 🚀

What's the deal with #bitcoin fees? How are they calculated? Where do they go? Let's have a look with a #DecodingBitcoin 🧵 A transaction's fee is equal to the total amount of bitcoin in the inputs, minus the total amount of bitcoin in the outputs.

Buckle up for today's #DecodingBitcoin🧵. It's a long one but we promise it's worth your time. Today we're going to break down how to sign a #bitcoin segwit transaction. We'll use a real example from the BIP-143 test vectors (that’s one of the segwit BIPs!)

We’ve got a good #DecodingBitcoin🧵for you today. The topic? 𝐄𝐧𝐝𝐢𝐚𝐧𝐧𝐞𝐬𝐬, AKA the order of bytes in a computer’s memory. When we put it like that it sounds a little boring, but there’s something interesting, and dare we say 𝑎𝑛𝑛𝑜𝑦𝑖𝑛𝑔, about how bitcoin handles endianness…

Let's talk about the 2 ways to track user balances on decentralized networks Account Model (#Ethereum): Tracks balances like a bank ledger (simple and intuitive). UTXO Model (#Bitcoin): Tracks specific unspent outputs from transactions (complex but powerful) a #decodingbitcoin🧵

There is an oft-repeated sentiment in the community that #bitcoin does not need you. While bitcoin is designed to be resilient, we 𝑑𝑜 need you. Bitcoin needs all the talent and energy it can gather to solve some of the most difficult technical problems of our time.
