Hi Bitcoiners – it’s Fran again.
17 years ago today, Hal Finney posted two words that changed everything: “Running bitcoin.”
Since then, thousands of bitcoiners across 50+ countries have run in his name.
The 5th #RunningBitcoinChallenge starts NOW. ⚡️🏃♂️

Hal believed code could set humanity free.
He was an avid runner, until progression of his ALS made it impossible.
The 2026 Running Bitcoin Challenge runs for 21 days starting today, the anniversary of his legendary tweet. 🌍
Run or walk 21 km / 13.1 mi– every step contributes to ALS research. 📷https://t.co/CvI3MyRx9G
This year’s challenge is backed by giants:
⚡️ @HRF – defending human freedom with Bitcoin
⚡️ @blocks – @jack’s company building on open money for the world
Hal would be grateful and proud of your support. Thank you!
We are also being supported by @strike - thank you!
I’m also proud to highlight HRF’s Finney Freedom Prize, honoring work at the intersection of Bitcoin, freedom, and privacy.
Congratulations to the 3rd halving era’s winner, Andreas M. Antonopoulos - who educated millions on Bitcoin and its potential for humanity.
Hal would be proud of your work. 🏆
I’m Fran Finney (@franfinney), Hal’s wife.

"look the LLM was wrong about this one thing it's useless" people should join up with the "look the LLM got this one thing right it can do anything" people and fuck off together

A side project I've been building lately. I built a neural net with Tensorflow and trained it on the MNIST dataset of handwritten images. Then, I brought the model into Blender and used the values to turn it into a 3D scene. This is actually the model running!

No sugar coating this, it's been a challenging few months. The Truffle Suite will be sunsetting over the next 90 days.
To all the developers who've supported us, thank you! It's been an absolute joy to strive with you & the Ethereum ecosystem for the past 6 years. 🧵
