Linus Tech tips coverage of CES 2014 is brought to you by nc.com your source for

2
00:00:05,319 --> 00:00:11,559
great technology selection and service along with Corsair memory and Western

3
00:00:09,920 --> 00:00:14,879
Digital hey guys we're here checking out Bitcoin and Butterfly Labs and they had

4
00:00:13,519 --> 00:00:19,240
something that caught my eye immediately I'd actually seen a mini press release about this before I came to the booth

5
00:00:18,119 --> 00:00:23,840
and just wasn't sure where they were because there's a little bit of a mixup and was really excited when I saw it so

6
00:00:22,439 --> 00:00:28,599
what can you tell me generally about this product so we have our new monarch

7
00:00:26,000 --> 00:00:33,800
product it's our 600 gigahash high-capacity as6 mining card and it's

8
00:00:31,759 --> 00:00:37,680
actually a dual dual system where you can use it as a PCI Express card or you

9
00:00:35,920 --> 00:00:42,120
can use it outside of your computer as a USB device and it we were're going to

10
00:00:40,520 --> 00:00:46,960
offer a number of different options for it from Air cooling water cooling and uh

11
00:00:45,079 --> 00:00:51,000
in both an open loop and a Clos Loop version the that open loop version looks

12
00:00:49,360 --> 00:00:56,280
absolutely insane you guys did a really good job with that and I like that you guys have all the different variations

13
00:00:54,120 --> 00:00:59,320
that someone could possibly want now how how can you go about connecting this I

14
00:00:57,640 --> 00:01:02,559
know there's the USB version like what what requirement do you need for that

15
00:01:01,079 --> 00:01:08,080
you just minimal requirements you can use an Android laptop you can use Mac

16
00:01:04,839 --> 00:01:10,360
you can use a Windows and it's it's just

17
00:01:08,080 --> 00:01:14,520
standard USB and you can use just about any mining program I know Mac Miner

18
00:01:12,000 --> 00:01:19,479
supports it bit Minter CG Miner BFG Miner and of course our own Easy minor

19
00:01:17,040 --> 00:01:23,600
and then for connectivity sake uh a USB header can take a crazy amount of these

20
00:01:21,640 --> 00:01:28,000
so you just need PCI Express power two pin uh two sets of six pins and then a

21
00:01:26,400 --> 00:01:33,360
USB header of some sort to go to the card right yeah and for every single

22
00:01:31,040 --> 00:01:38,439
Root Hub in your so every USB chip in your computer you can have up to 126 127

23
00:01:36,439 --> 00:01:41,119
devices connected to it so that's an absolutely insane amount of devices I

24
00:01:40,040 --> 00:01:44,759
know I've seen quite a few of you guys on the Forum purchasing up a bunch of

25
00:01:43,040 --> 00:01:47,960
really cheap power supplies and running a few cards off it this is a pretty good

26
00:01:46,680 --> 00:01:52,680
idea for that because it's not going to take a crazy amount of power to power each one and you just have a couple

27
00:01:51,000 --> 00:01:58,560
power supplies powering your extra cards which is not a bad idea yeah each unit

28
00:01:55,200 --> 00:02:00,240
actually consumes roughly 350 Watts yeah

29
00:01:58,560 --> 00:02:04,840
the main I've seen is this like uh it's a pretty offbrand about 20 $25 450 wat

30
00:02:03,159 --> 00:02:08,080
power supply that people are buying tons of and running a bunch of cards so that

31
00:02:06,240 --> 00:02:11,120
would be perfect nice yeah now what can you tell me about this Hardware wallet

32
00:02:09,520 --> 00:02:16,160
I've seen so our newest product is called the bitsafe and it is a hardware

33
00:02:13,800 --> 00:02:20,920
wallet and it will basically store your private Keys securely and never expose

34
00:02:18,760 --> 00:02:26,879
them to the host computer so you could take this Hardware wallet out to a a

35
00:02:24,440 --> 00:02:31,480
public machine a internet cafe it may even be compromised and have malware on

36
00:02:28,640 --> 00:02:35,879
it and working with some of the wallet manufacturers uh such as blockchain

37
00:02:33,400 --> 00:02:41,640
Armory that sort of thing we will you'll basically be able to send a request to

38
00:02:38,360 --> 00:02:43,440
sign a transaction and it will go to the

39
00:02:41,640 --> 00:02:48,040
bitsafe the bitsafe will sign it internally and send it back out so the

40
00:02:45,480 --> 00:02:52,280
private keys will never be exposed and you'll never have to worry about your

41
00:02:49,599 --> 00:02:55,120
Bitcoins being stolen the future is here that's freaking cool you can have a

42
00:02:53,519 --> 00:02:59,080
hardware wallet that's awesome because I've been I've been wondering about how that goes and it's interesting because

43
00:02:58,159 --> 00:03:04,519
every once in a while you hear that someone will lose their wall wallet yes it's just like oh God and well you also

44
00:03:02,720 --> 00:03:08,239
be when you first instantiate your wallet you'll be able to print out a

45
00:03:06,000 --> 00:03:12,000
paper backup stored in your safe so even if you lose your Hardware wallet you

46
00:03:10,120 --> 00:03:15,400
just get a new one and you reload it onto that wallet it's a really good idea

47
00:03:13,879 --> 00:03:19,080
we've heard some a few horror stories about that so one of the features that

48
00:03:17,480 --> 00:03:23,239
we're including with it is actually a solar cell on the back so you can leave

49
00:03:21,239 --> 00:03:28,400
it sitting on your desk or what have you and it will charge the battery you can

50
00:03:25,280 --> 00:03:30,879
and the screen is a version of eink that

51
00:03:28,400 --> 00:03:36,280
is very low power so it will even operate the screen directly if you are

52
00:03:34,319 --> 00:03:40,959
very low on batteries you can charge it via USB but as long as you let it sit in

53
00:03:38,760 --> 00:03:43,720
the light it'll charge itself I find a lot of these devices that you you're

54
00:03:42,239 --> 00:03:48,319
able to just sit in pretty much any light they never really die anyways because as long as you don't keep it in

55
00:03:46,360 --> 00:03:51,799
your pocket 24/7 they'll usually have some amount of charge and you said it's

56
00:03:49,799 --> 00:03:57,360
really low power too right right yes the the eing screen just uses just very

57
00:03:53,840 --> 00:03:58,480
minimal amount of power and it'll it's

58
00:03:57,360 --> 00:04:03,200
we're trying to make as low power so it'll last as long as possible without ever having to recharge now can you

59
00:04:01,879 --> 00:04:08,560
explain the different options you have when going through a transaction with this thing like what what what can it do

60
00:04:06,159 --> 00:04:11,640
in terms of transactions so addition to being able to plug it into a host

61
00:04:09,840 --> 00:04:15,200
computer the main feature and probably the main way people will use it is via

62
00:04:13,400 --> 00:04:20,400
the camera that it will have and you'll be able to scan QR codes with it it will

63
00:04:17,880 --> 00:04:22,919
also be able uh we're still debating on whether or not we're going to have a

64
00:04:21,280 --> 00:04:27,440
Bluetooth module where you can send that in real time but the the camera will

65
00:04:25,280 --> 00:04:32,960
allow you to use QR codes such as a like a lamu uh ATM or someone's smartphone or

66
00:04:30,880 --> 00:04:36,880
even another bit safe which uh the bit safe will be able to display a QR code

67
00:04:34,440 --> 00:04:41,720
for receiving and another bit safe will be able to send to that one so if you

68
00:04:38,880 --> 00:04:45,360
had if you and a a customer or a buddy or something had two bit safes you could

69
00:04:43,680 --> 00:04:49,440
theoretically just take pictures of each other's QR codes and transfer Bitcoins

70
00:04:47,120 --> 00:04:53,680
that way yes absolutely so if you're out for dinner one night you be like hey you

71
00:04:50,880 --> 00:04:57,280
owe me you owe me quarter Bitcoin you can send it right there from bit safe to

72
00:04:55,160 --> 00:05:00,280
bit safe that's awesome how much would each one of these individual units cost

73
00:04:58,960 --> 00:05:06,560
and the hardware each card will run it right now runs

74
00:05:03,320 --> 00:05:08,919
$2,100 for the 600 gash for the 300 gash

75
00:05:06,560 --> 00:05:13,120
I think it's around $1,200 the hardware wallet we want to make it as cheap as

76
00:05:11,160 --> 00:05:16,440
possible and we keep trying to get the price down get the price down it looks

77
00:05:14,720 --> 00:05:21,680
like right now it'll be probably in the $150 range I would love to get a some

78
00:05:19,800 --> 00:05:26,199
sort of device maybe not the bit safe itself but something in the $3 or $40

79
00:05:24,120 --> 00:05:30,360
range something we're looking at I don't know if we can do it with uh at least

80
00:05:28,720 --> 00:05:33,759
with all the features we want but it's something we definitely want to do I i'

81
00:05:32,319 --> 00:05:36,800
I've got a few people that I know that have more expensive wallets than that so

82
00:05:35,680 --> 00:05:41,280
while while it is a little bit up there and I'd like to see around 3040 as well

83
00:05:38,960 --> 00:05:44,680
I I could see a few people buying it thanks for watching our our butterfly
