SeedSigner v0.8.6, the "Bigger Picture" release is out!
TLDR:
. Support for larger displays
. 7 new language options
Link to the full release notes & binaries:
https://github.com/SeedSigner/seedsigner/releases/tag/0.8.6
Support for larger displays means on-screen text is easier to read and makes more efficient outgoing QR communication possible. The new display hat shown below incorporates one of these larger screens.
Seven new languages -- French, Chinese, Catalan, Dutch, German, Italian and Japanese -- mean many more people can now interact with a SeedSigner in their native tongue. The map below gives an approximation of what our updated language coverage looks like.
More languages are coming soon, including right-to-left languages (e.g. Arabic, Persian, Hebrew, etc.) that will add significant additional global coverage. If there is a language you would like to see in an upcoming release, there are relevant instructions in our release notes.
As usual, you don't have to take our word on what makes up the release binaries; our releases are reproducible and instructions to build your own binaries can be found at:
https://github.com/SeedSigner/seedsigner-os/blob/main/docs/building.md
SeedSigner continues to be the work of a core group of volunteer contributors, as well as a growing collection of auxiliary technical contributors who engage with the project when their time/interests/skills align.
If you are getting value from the SeedSigner project, please take a moment to send some sats to our core technical contributors -- all tips, small and large, are **greatly** appreciated and go a long way to incentivize continued development:
https://seedsigner.com/donate/
Our project embodies what volunteer, collaborative, low time preference, open source, bitcoin-only, building "out in the open" looks like.
We continue to improve on our core concept of trust-minimized, self-sovereign cold storage out of love for bitcoin, & our fellow bitcoiners.

🚨 Announcing SeedSigner 0.8.5 !!! 🚨
Our first multi-language release, featuring Español!
Keep reading and please see the attached images for additional details. 👇
First off, how to activate the Spanish UI -- just update to this latest version, navigate to the "Language" option in the signer's settings, and from there you can now select Español as an option. 🧡
Work on this release has taken a meandering FOSS path, with @npub1tv8…7wn2 starting the initial effort more than 2.5 years ago -- @npub177z…dp8e kept the flame burning for some time…
We immensely appreciate the instrumental help from Ronny Avenando, Max Apogee and @npub12vd…du57, two of whom also made their first PRs!
More western and English-similar languages should quickly follow (e.g. Portuguese, German, French, Italian, Dutch, Czech, etc.). Other languages may take more time but work on them will continue...
Some translation teams have already been assembled, but if you would like to see if an effort to add a specific language has already been initiated (see image below)...
The comment below shared in our dev chat by our Project Manager @npub1d9v…zk2u says a lot about how we view the importance of this release. 🧡
A big thank you to our core contributors, and to ALL of the other people that played a role in this effort. 🙏

The majority of the bitcoin industry is not incentivized to share what we've built -- please help us get the word out! 🧡 🙏 https://image.nostr.build/98fb6b3b30f59921121f7cd786a45ea55a8757a148575aa3deb0d9a678b1dbf0.jpg

Giving people the opportunity to put less trust in centralized third parties is not "UX regression".
When a commercial HWW verifies firmware/software at power-on, users are trusting they're using authentic hardware, and they're outsourcing the verification process to the same entity that produces both the hardware and the software.
For many users these choices will make sense, but for some they won't -- it's good for people to have options to choose from.

Any safety concerns there? Don't know what to believe based on things i see / hear.

2024-09-26 14:08:40 GMT

TLDR for those who missed this:
. RPi 0, 0W, 02W, 2 & 3 have permanent ROM that is burned in at the factory
. "Firmware" is split between the Pi AND the microSD
. Verifying the code on the microSD is authentic is vital, but simple
. Sharing a signer is not ideal, but can be viable w/ trusted 3rd parties #note1jkx…fpsl

At some point, Nunchuk stopped supporting static XPUBs. If you change your SeedSigner to the Sparrow export setting, it will animate the QR code that depicts the XPUB and the rest should work fine. I ran into this a couple of weeks ago as well.

Just so you know, that is not me. No idea who "Roberts" is. I was an LEO however, but have been very candid that digital forensics was my specialty. You should really double check it your sources, would have been easy to find this out.

We trust the manufacturer to do a lot less. We don't trust the device to validate software, we don't trust it to persistently store keys, and we don't trust it to make wireless or wired connections with other devices. We just trust it to execute SeedSigner code.

As of right now, just one, but progress on more is ongoing. But you're missing the point, it's not worth it to target the entire RPi supply chain at this point, and even if you wanted to target individuals, less than 0.01% of RPi products likely will end up as SeedSigners, so who knows which ones to pick. Whereas, at a certain point in a HWW's life, it's known that the device will be used to store PKs, and an attacker further knows that just about every device is going to someone who will potentially use it for that purpose. Different tradeoffs.

With SeedSigner yes, but unfortunately BlueWallet does not support testnet. You can, however, go through the same workflow with either Nunchuk on mobile, or sparrow wallet on the laptop/desktop and use testnet. The experience with bluewallet is much the same.

Different set of tradeoffs that not all grok, in part likely because bitcoiners are perpetually bombarded with a marketing narrative declaring HWWs as the most secure way to interact with private keys. Different tools are appropriate for different people and different use cases, but SeedSigner is entirely a viable option "in practice".

YubiKey has a larger security budget than your favorite HWW -- hardware security is a never-ending cat and mouse game.
Better to put your trust in functionally unsolvable math problems rather than "unhackable" hardware. https://image.nostr.build/4fac5912deb2f6f8387a9d6fba217b7158ac1e2a4dbcc46b45ef2971b8dc3544.jpg #note1704…a77f

None of the coordinators support anti-exfil so in part it's a chicken and egg problem, but hoping deterministic signature validation is incorporated into the psbt standard, that would be the best ux solution, rather than a second round of QR code exchange. Validating and deploying authentic software takes less than a minute, and we've always been about long term saving with bitcoin with relatively few spends, so card swap attack risk seems overblown when validating software is so fast and simple. With great power comes great responsibility, for those who are willing to assume the responsibility. Also, take a closer look at those emphasizing these issues and their motivations; it speaks to conflicts of interest that you've spoken about.

2024-08-31 12:57:49 GMT

In addition to being an "I can't buy hardware wallets" option, SeedSigner is also an "I'm not comfortable trusting hardware wallets" option.

If a guy reselling hobbyist electronic components and 3d printed parts out of his basement makes you nervous about your multi-million dollar company's profit model, there likely are issues with the products you're offering, and/or the amount of value you're delivering to your customers.
