 Linus Tech Tips coverage of CES 2014 is brought to you by NCIX.com, your source for great technology, selection and service, along with Corsair memory and Western Digital. Hey guys, we're here checking out Bitcoin and Butterfly Labs, and they had something that caught my eye immediately. I'd actually seen a mini press release about this before I came to the booth, and just wasn't sure where they were because there's a little bit of a mix-up, and was really excited when I saw it. So what can you tell me generally about this product? So we have our new Monarch product, it's our 600 GHz high capacity ASIC mining card, and it's actually a dual system where you can use it as a PCI Express card, or you can use it outside of your computer as a USB device. And we're going to offer a number of different options for it, from air cooling, water cooling, in both an open loop and a closed loop version. That open loop version looks absolutely insane, you guys did a really good job with that, and I like that you guys have all the different variations that someone could possibly want. Now, how can you go about connecting this? I know there's the USB version, what requirements do you need for that? Just minimal requirements, you can use an Android laptop, you can use Mac, you can use Windows, and it's just standard USB, and you can use just about any mining program. I know MacMiner supports it, Bitminter, CGminer, BFGminer, and of course our own Easyminer. And then for connectivity's sake, a USB header can take a crazy amount of these, so you just need PCI Express power, two sets of six pins, and then a USB header of some sort to go to the card. Right, yeah, and for every single root hub in your, so every USB chip in your computer, you can have up to 126, 127 devices connected to it. So that's an absolutely insane amount of devices, I know I've seen quite a few of you guys on the forum purchasing up a bunch of really cheap power supplies and running a few cards off it. This is a pretty good idea for that, because it's not going to take a crazy amount of power to power each one, and you can just have a couple power supplies powering your extra cards, which is not a bad idea. Yeah, each unit actually consumes roughly 350 watts. Yeah, the main I've seen is this like, it's a pretty off-brand, about $20, $25, 450 watt power supply, that people are buying tons of and running a bunch of cards, so that would be perfect. Now what can you tell me about this hardware wallet I've seen? So our newest product is called the BitSafe, and it is a hardware wallet, and it will basically store your private keys securely and never expose them to the host computer. So you could take this hardware wallet out to a public machine, an internet cafe, it may even be compromised and have malware on it, and we're working with some of the wallet manufacturers, such as blockchain, armory, that sort of thing. You'll basically be able to send a request to sign a transaction, and it will go to the BitSafe, the BitSafe will sign it internally and send it back out, so the private keys will never be exposed, and you'll never have to worry about your bitcoins being stolen. The future is here, that's freaking cool, you can have a hardware wallet, that's awesome, because I've been wondering about how that goes, and it's interesting because every once in a while you hear that someone will lose their wallet. Yes. That's just like, oh god. Well you'll also be able to, when you first instantiate your wallet, you'll be able to print out a paper backup, store it in your safe, so even if you lose your hardware wallet, you just get a new one and you reload it onto that wallet. That's a really good idea, we've heard a few horror stories about that. So one of the features that we're including with it is actually a solar cell on the back, so you can leave it sitting on your desk or what have you, and it will charge the battery. And the screen is a version of E Ink that is very low power, so it will even operate the screen directly if you are very low on batteries. You can charge it via USB, but as long as you let it sit in the light, it'll charge itself. I find a lot of these devices that you're able to just sit in pretty much any light, they never really die anyways, because as long as you don't keep it in your pocket 24-7, they'll usually have some amount of charge, and you said it's really low power too, right? Right, yes, the E Ink screen just uses just a very minimal amount of power, and we're trying to make it as low power so it'll last as long as possible without ever having to recharge. Now can you explain the different options you have when going through a transaction with this thing, like what can it do in terms of transactions? So in addition to being able to plug it into a host computer, the main feature, and probably the main way people will use it is via the camera that it will have, and you'll be able to scan QR codes with it. It will also be able, we're still debating on whether or not we're going to have a Bluetooth module where you can send that in real time, but the camera will allow you to use QR codes such as a, like a Lamassu ATM, or someone's smartphone, or even another BitSafe, which the BitSafe will be able to display a QR code for receiving, and another BitSafe will be able to send to that one. So if you and a customer or a buddy or something had two BitSafes, you could theoretically just take pictures of each other's QR codes and transfer Bitcoins that way? Yes, absolutely. So if you're out for dinner one night, you'd be like, hey, you owe me a quarter Bitcoin, you can send it right there from BitSafe to BitSafe. That's awesome. How much would each one of these individual units cost, and the hardware wallet? Each card will run, right now runs $2,100 for the 600 giga hash, for the 300 giga hash I think it's around $1,200. The hardware wallet, we want to make it as cheap as possible, and we keep trying to get the price down, get the price down. It looks like right now it'll be probably in the $150 range. I would love to get some sort of device, maybe not the BitSafe itself, but something in the $30 or $40 range, something we're looking at. I don't know if we can do it with, at least with all the features we want, but it's something we definitely want to do. I've got a few people that I know that have more expensive wallets than that, so while it is a little bit up there, and I'd like to see around $30, $40 as well, I could see a few people buying it.
