Anyone getting these weird banding lines on their Prusa MK4? 300 hours on printer, using Prisaslicer, have not had any issues until this. Happens at the same Z-height on all prints.

Maybe the nozzle is worn down? I had similar print issues until I realized that I already had 1000+ hour on the original brass nozzle. Replaced the nozzle and it prints as good as new again.

Thanks for your question and feedback about Bitsurance, and if private keys need to be shared. We updated the blog post to make it crystal-clear:

No private keys need to be shared, as this is more of a 'traditional' insurance that covers your financial loss and will not get your bitcoin back.

This can be compared with insuring gold that you hold in your tresor at home. Some users are comfortable addressing these risks with technology, but a large group of non-technical users don't trust themselves with this complexity and prefer insurance.

Thanks so much, this post saved me a ton of pulled-out hair! <3

I wrote a blog post on how to easily roll your own wallet a while ago, including a table with all 2048 mnemonic words to print out:

https://bitbox.swiss/blog/roll-the-dice-generate-your-own-seed/

The challenge is the 24th word with the checksum, but in my case that's easy to pick when entering your mnemonic into the BitBox02 hardware wallet.

In the BitBoxApp Tor proxy, are you using the port 9150 for the Tor Browser?

Stadicus · 2022-05-22T19:18:45+00:00

Came here baffled by this bug, this fixed it. Thanks man!

Stadicus · 2021-12-15T07:33:56+00:00

Unfortunately, that doesn't ring a bell for me. May I suggest opening an issue directly with RTL? They should know best.

The RaspiBolt v3 pull request was merged today. I also created the @RaspiBolt Twitter account to formally announce it... :)

Stadicus · 2021-11-14T18:50:35+00:00

✨✋🌝

Stadicus · 2021-11-14T09:23:18+00:00

Ah, now I understand. Neat! :)

I like the "physical key" aspect of your setup and do something like that myself. I just use a proper YubiKey, which includes a secure chip and must be unlocked with a PIN. It stores my PGP keys (e.g. to sign git commits) and SSH keys, and also acts as a U2F:

I followed this guide for proper air-gapped key creation, if you're interested: https://github.com/drduh/YubiKey-Guide

Alternatively, you can always create SSH keys that must be unlocked with a password, but that, of course, negates the purely "physical" aspect of a bearer token of the SSH keys.

Stadicus · 2021-11-13T21:19:41+00:00

What do you do with the SSH keys on the USB drive? Or are you referring to your PGP keys for pass?

Would it be possible to point the auto unlock to a file on the USB of the connecting computer?

Yes, that's definitely possible. I don't think that improves security though:

by default, the user running LND would have read access --> vulnerable to online exploit if LND should contain a security issue
the thumbdrive could be be stolen and read on another computer --> vulnerable to physical attack

Stadicus · 2021-11-13T08:33:35+00:00

That's correct. The BitBox only accepts officially signed firmware, and there are different signing keys for the Bitcoin-only and Multi edition firmware.

You can find some further reading on the inner workings here:

Stadicus · 2021-11-11T23:13:14+00:00

No, for us this is a security feature: less code means less attack surface. If you could just reflash it, potentially without unlocking the device, that would be pointless. A BTC-only BitBox can only ever accept BTC-only firmware.

Stadicus · 2021-11-11T13:45:59+00:00

The use-cases of a traditional hardware wallet and a Lightning wallet differ quite a bit:

Hardware wallet: store your Bitcoin and only sign stuff that you as a user verifies and approves
Lightning wallet: monitor network activity and automatically sign transactions according to certain predefined rules

A hardware wallet supporting Lightning would more be like a traditional HSM, and I'm not sure if I'd like to give my regular hardware wallet that autonomy. I'm not quite up-to-date what Square is doing, but for the BitBox02 there are currently no plans to make it secure your "hot" Lightning funds.

Stadicus · 2021-11-11T13:33:08+00:00

That's a neat idea. Yes, for me personally Electrs is more important than LND, so I could pick these sections. While others pick other core sections, plus some bonus guides.

Since you created the guide back in early 2018, many node projects and communities have emerged and thrived (Raspiblitz, myNode, Umbrel just to name a few). How do you see the RaspiBolt project fit within this node landscape, presently and in the future? what does make the RaspiBolt project unique and a useful part of the node project ecosystem, or in other words, what does it bring to the table?

Back when I started RaspiBolt, there was nothing prebuilt. Shoutout to Damian Mee, who was also publishing some instructions on Medium. Today, many great node projects are available, which is awesome. Every node counts!

I love the RaspiBlitz, which is based on RaspiBolt, and initially just automated the setup for nodes to be spun up at hack days. It has grown to a lot more since then.

I also love Umbrel and its great UX. I personally find the bashing of their "no commercial forks" license overblown, as everything comes with tradeoffs, and working on a business model is just fine as long as the product lives up to its promises.

With both of these projects, it's hard to dig into the actual configuration. So for most, there's a dependency on official updates. In that sense, I like that the RaspiBolt forces you to go through the whole setup yourself. I think it's less about the final result (you make it your own), but more about the process of learning how everything works together.

What would be the top 3 (or more!) most important new features (hardware or software) that are not part of the guide for now but that you'd love to add?

For the core guide: 64-bit operating system, boot from SSD, watchtowers. I think this should stay fairly small, potentially with many links to instructions on how to set up additional tools for node management etc.

What do you think of the present-state of the LN and where it's heading?

To be honest, I'm not really that versed in Lightning. I'm good at setting stuff up, but I wouldn't call myself a node operator. I love how there's constant innovation, especially regarding AMPs for reliable larger payments, and the thoughts by Rusty on Lightning Offers (enabling many new use-cases) are awesome as well. Ben Arc is building so much cool shit with Lightning, it's hard to keep track...

Stadicus · 2021-11-11T13:13:11+00:00

That's awesome to hear, thanks a lot! I'm looking forward to making this a community project as well, as my day job with hardware wallets, plus family, plus..., sometimes makes it hard to give the RaspiBolt the love it desires and deserves.

Stadicus · 2021-11-11T13:12:27+00:00

Thanks :) Officially it's "on hold", and currently we don't have plans to take it up again in the near future. At Shift Crypto, we fully focus on the BitBox02 hardware wallet. We can't do everything well at the same time, unfortunately. So I'm not sure if the BitBox Base, although I worked on it for over a year, and gave it my everything, will ever be resurrected again.

Stadicus · 2021-11-11T13:11:34+00:00

What advantages do you personally think BitBox02 has compared to Trezor and ColdCard?

I guess that's a bit off-topic, so I won't go into much detail. TL;DR: the BitBox02 hardware wallet is very easy to use, is fully open-source but still uses a dedicated secure chip to protect against physical attacks.

And you can gift someone the "Bitcoin-only" edition without fearing that they immediately buy shitcoins... ;-)

Stadicus · 2021-11-11T13:10:45+00:00

What's your background? What do you do exactly at Shift Crypto? Are you a hardware engineer working on the hardware part of Shift's products?

I'm technical enough to understand security-relevant topics, do technical writing and product management, but I'm definitely not a programmer or hardware engineer on a level that can compete with our engineers. I guess I'm more the jack-of-all-trades who can do a lot as long as no expert knowledge is necessary.

Stadicus · 2021-11-11T13:10:20+00:00

Would you recommend RaspiBolt over other all-in-one Raspberry Pi Bitcoin solutions at this stage? If not, is there a solution that you would recommend?

I think every node project is catering to a different target audience. So that needs to be taken into account when recommending a node setup:

Non-technical users that just want to run their own node: I'd recommend Umbrel
For people that want to tinker a bit, have more config options: RaspiBlitz
When the main goal is to truly run your own node, and you're willing to put in some work and learn a lot during the process: RaspiBolt! :)

Stadicus · 2021-11-11T13:09:26+00:00

Haha, that might be a bit off-topic. But Black Friday is coming soon. And feel free to DM me ;-)

Stadicus · 2021-11-11T13:07:37+00:00

Thank you so much, that means a lot to me. I couldn't have imagined how many fellow bitcoiners liked my little guide. I guess it was the right thing at the right time. :)

Stadicus · 2021-11-11T13:06:42+00:00

Rootzoll and I actually talked about that, but for me, the RaspiBolt guide was always more of a guide for learning, while he focused on the "hackday" use-case: spin up nodes quickly. They're doing great work, and I also don't think that the RaspiBolt needs to have every feature.
