Coldcard Dicerolls: Verification Report

I spent a lot of time today verifying the Coldcard Diceroll seed path in multiple firmware versions. The implementation is correct and can generate up to 256 bits of entropy with 100 dice rolls.

Full report below.

portlandhodl.github.io Miniscript Studio: design self-custody you can survive Visual, block-based Miniscript. Fault tolerance vs. interactivity, made visible. Runs entirely in your browser.

We need accessible and intuitive miniscript UI/UX. I am not convinced a threshold multi-vendor multisig is a silver bullet for self custody alone.

The fault tolerance at the cost of interactivity trade-off is essential for giving uses a way out under the worst of circumstances.

AI is software's Tower of Babel moment. Bitcoin consensus clients won't be an exception to this.

Given anyone can make a robust implementation or modification. The consensus implementation will be the one that produces the most economic value when taken into account fork risk.
