Greetings to all the new Summer of Bitcoin future contributors!

As you all probably already know, SeedSigner is a 100% volunteer, completely open source project. There is no company. We have no VC funding. We have no advertising budget. If people share info about SeedSigner with others it's because they love what we've been building.

However, we have a ton in place that rivals what you'd expect to see from a well-funded corporation. Our overall code quality and code organization/structure, our INCREDIBLE UX designed by @easyuxd, our test suite and screenshot generator, github automations, internal code review processes, etc.

Some FOSS projects are more on the YOLO hacker side of things; nerds building complex, hard to use software meant for other super nerds, often with big messy late night code sprints.

Instead, we try to maintain tight professional standards as much as possible (though since we're all just volunteers, often that rigor comes with the tradeoff that we're SLOW).

These test scripts demonstrate the step-by-step speed ups that the various ccaches provide.

Scripted test sequence:

Start a build w/totally empty cache(s).
Rebuild the same target with the now populated cache(s).
Change to a new target and get some speedup via the populated cache(s).
Rebuild that target to get the full speedup.
...repeat for the remaining two targets.

The first script is for a SeedSigner OS builder that only has the built-in BuildRoot ccache.

Release Candidate 0.8.5-rc1

🔥 ¡SeedSigner en español está aquí! 🔥

⚠️ Pre-Release Notice:

This is a Release Candidate (RC) version of SeedSigner. It is meant for TESTING to help us discover bugs, identify translations that can be improved, UI problems, performance issues, etc.

Submitting SeedSigner translation changes

Create an account on github.com if you haven't already.

Finish translation changes, download .po file

Update and review translations in Transifex.

ASIC Manager

Installation

Create virtualenv and install python dependencies:

python -m venv envs/asic_manager-env
pip install -r requirements.txt

I'm using python3.11 but any recent-ish python3 should be fine.

SeedSigner "firmware" isn't what you think it is

On Rabbit Hole Recap #320, ODELL said:

"If you are using a SeedSigner in single sig you have to make sure that that device never leaves your sight. If someone gets access to it, they can put malicious firmware on it. [...] And this idea that you're going to share it among communities in single sig is batshit crazy. That is not a good trust model."

This was a few weeks back. Things have gotten spicier since.

My goal here is to LOWER the temperature.

SeedSigner v0.8.0 Release Notes

Quick Highlights:

Addtional legacy signing support:

P2PKH (bip44): Legacy format dating back to 2014.
P2SH multisig (bip45): Legacy multisig (also 2014).
