1
00:00:00,000 --> 00:00:02,940
All right. Welcome everyone to another deep dive today.

2
00:00:02,940 --> 00:00:06,700
We're going to be talking about matrix and as always,

3
00:00:06,700 --> 00:00:09,600
we'll be diving deep into the source material, but you know,

4
00:00:09,600 --> 00:00:12,800
our goal today is really to help you understand what matrix is all about.

5
00:00:12,800 --> 00:00:15,080
Even if you're not like super technical,

6
00:00:15,080 --> 00:00:18,800
we want to make sure you can follow along and you know,

7
00:00:18,800 --> 00:00:20,880
really get something out of this. Absolutely.

8
00:00:20,880 --> 00:00:23,960
It can be a bit daunting getting started with something new,

9
00:00:23,960 --> 00:00:25,240
especially in the tech world,

10
00:00:25,280 --> 00:00:30,280
but matrix at its heart is all about making communication more open and secure

11
00:00:30,280 --> 00:00:34,640
and that's something everyone can benefit from. Right? Right. Exactly.

12
00:00:34,640 --> 00:00:36,200
So before we jump in,

13
00:00:36,200 --> 00:00:40,080
I do want to give a quick shout out to our sponsor this week, safe server.

14
00:00:40,080 --> 00:00:43,520
They're all about providing secure hosting and that's actually a really important

15
00:00:43,520 --> 00:00:46,440
concept when you're talking about taking control of your digital life,

16
00:00:46,440 --> 00:00:48,120
which is kind of what matrix is all about too.

17
00:00:48,120 --> 00:00:50,840
So if you're interested in learning more about what they do,

18
00:00:50,840 --> 00:00:54,520
you can check them out at www.saveserver.de.

19
00:00:54,880 --> 00:00:58,640
Definitely worth a look, especially as we delve deeper into this topic.

20
00:00:58,640 --> 00:01:02,000
Okay, so let's get to the heart of it. What exactly is matrix?

21
00:01:02,000 --> 00:01:04,520
Imagine if you took the idea of email, right?

22
00:01:04,520 --> 00:01:07,040
But instead of just sending messages back and forth,

23
00:01:07,040 --> 00:01:09,560
you could have instant chats, group conversations,

24
00:01:09,560 --> 00:01:12,200
and even build your own communication tools on top of it.

25
00:01:12,200 --> 00:01:14,040
That's essentially what matrix is all about.

26
00:01:14,040 --> 00:01:18,360
It's like this whole ecosystem for communication. And just like with email,

27
00:01:18,360 --> 00:01:21,000
you have your email app like Gmail or Outlook,

28
00:01:21,000 --> 00:01:24,520
and then you have your email provider like Google or your internet company.

29
00:01:24,800 --> 00:01:27,880
Right. Well, matrix has similar components.

30
00:01:27,880 --> 00:01:31,280
We've got some great documentation from matrix.org itself that we're going to be

31
00:01:31,280 --> 00:01:32,840
using to help us understand all this.

32
00:01:32,840 --> 00:01:33,360
Yeah.

33
00:01:33,360 --> 00:01:36,360
And one of the first things that jumps out when you look at their website is this

34
00:01:36,360 --> 00:01:41,360
idea of matrix being an open network for secure decentralized communication.

35
00:01:41,360 --> 00:01:44,800
Now that might sound like a mouthful,

36
00:01:44,800 --> 00:01:46,960
but it's actually a really important concept.

37
00:01:46,960 --> 00:01:50,840
It means that unlike some of the other messaging apps you might be used to,

38
00:01:50,840 --> 00:01:55,840
like say WhatsApp or Facebook messenger matrix isn't controlled by any one company.

39
00:01:55,840 --> 00:01:59,240
It's designed to be more like the internet itself,

40
00:01:59,240 --> 00:02:03,440
where different servers can connect and talk to each other and no single entity

41
00:02:03,440 --> 00:02:05,720
has control over the entire network.

42
00:02:05,720 --> 00:02:08,480
Okay. So it's kind of like this distributed network then,

43
00:02:08,480 --> 00:02:11,400
but how does all that work in practice?

44
00:02:11,400 --> 00:02:14,840
What are the key pieces that make up this whole matrix ecosystem?

45
00:02:14,840 --> 00:02:18,160
Well, the documentation talks about these elements of matrix, right?

46
00:02:18,160 --> 00:02:20,440
And they break it down into a few key parts.

47
00:02:20,480 --> 00:02:22,800
The first one is something called a home server.

48
00:02:22,800 --> 00:02:26,920
Think of it like your own personal base station within the matrix network.

49
00:02:26,920 --> 00:02:30,040
It's a piece of software that stores your account information,

50
00:02:30,040 --> 00:02:31,600
your messages and all that good stuff.

51
00:02:31,600 --> 00:02:34,120
So it's kind of like the email server for your matrix account.

52
00:02:34,120 --> 00:02:38,000
Yeah, exactly. Just like your email provider has solvers that handle all your

53
00:02:38,000 --> 00:02:42,200
emails, your matrix home server does the same for your matrix messages.

54
00:02:42,200 --> 00:02:46,040
And each home server has its own unique address, just like a website.

55
00:02:46,040 --> 00:02:48,880
So your matrix ID, which is like your username,

56
00:02:49,080 --> 00:02:52,360
looks something like at your name dot home server address dot com.

57
00:02:52,360 --> 00:02:55,080
Okay. I think I'm starting to get the picture here,

58
00:02:55,080 --> 00:02:59,880
but let's say I decide to get a matrix account and I choose a home server called,

59
00:02:59,880 --> 00:03:01,560
I don't know, matrix dot org.

60
00:03:01,560 --> 00:03:05,040
So my ID would be at the learner dot matrix dot org.

61
00:03:05,040 --> 00:03:09,200
Does that mean I can only chat with other people who also have a matrix dot org

62
00:03:09,200 --> 00:03:09,600
address?

63
00:03:09,600 --> 00:03:13,480
Nope. And this is where things get really cool because of this concept called

64
00:03:13,480 --> 00:03:17,000
federation, which is basically the ability for different matrix servers to connect

65
00:03:17,000 --> 00:03:20,840
and talk to each other. You can actually chat with anyone on any matrix server.

66
00:03:20,840 --> 00:03:23,880
It's like how you can send an email from your Gmail account to someone with a

67
00:03:23,880 --> 00:03:25,720
Yahoo address. It just works.

68
00:03:25,720 --> 00:03:28,760
Oh, I see. So even though my account is on matrix dot org,

69
00:03:28,760 --> 00:03:31,400
I could still chat with someone who's on a completely different server,

70
00:03:31,400 --> 00:03:33,560
like at friend dot their server dot net.

71
00:03:33,560 --> 00:03:36,800
Absolutely. And that's one of the things that makes matrix so powerful.

72
00:03:36,800 --> 00:03:41,000
It's this interconnected network where everyone can communicate regardless of

73
00:03:41,000 --> 00:03:42,280
where their account is hosted.

74
00:03:42,280 --> 00:03:46,440
And the documents even have a visual representation of this with different

75
00:03:46,440 --> 00:03:48,240
clients connected to different home servers,

76
00:03:48,240 --> 00:03:50,040
all participating in the same chat room.

77
00:03:50,040 --> 00:03:52,520
That makes sense. But I have to admit,

78
00:03:52,520 --> 00:03:56,800
thinking about all these servers talking to each other behind the scenes still

79
00:03:56,800 --> 00:03:58,000
makes my head spin a little.

80
00:03:58,000 --> 00:04:02,240
How does my message actually get from my phone to my friend's computer?

81
00:04:02,240 --> 00:04:04,000
If they're on a completely different server,

82
00:04:04,000 --> 00:04:06,800
it's actually pretty straightforward once you break it down.

83
00:04:06,800 --> 00:04:10,320
So when you hit send on your message, your matrix app,

84
00:04:10,320 --> 00:04:13,440
which they call a client sends it to your home server first,

85
00:04:13,760 --> 00:04:17,920
your home server then adds a digital signature kind of like a tamper proof seal

86
00:04:17,920 --> 00:04:21,160
and sends it over to the other home servers that need to receive it.

87
00:04:21,160 --> 00:04:25,560
Those servers then do a quick check to make sure everything is legit and then

88
00:04:25,560 --> 00:04:28,160
deliver the message to the intended recipient.

89
00:04:28,160 --> 00:04:32,440
So it's kind of like a relay race then my message goes from my phone to my home

90
00:04:32,440 --> 00:04:35,640
servers and to my friend's home server and finally to their phone.

91
00:04:35,640 --> 00:04:37,640
Yeah, that's a good way to think about it.

92
00:04:37,640 --> 00:04:41,440
And the really cool thing is that it all happens almost instantly thanks to the

93
00:04:41,440 --> 00:04:46,960
way matrix is designed. They use something called long-lived guineaf requests,

94
00:04:46,960 --> 00:04:51,040
which basically means that your client is constantly listening for new messages

95
00:04:51,040 --> 00:04:52,000
from your home server.

96
00:04:52,000 --> 00:04:55,760
So it's kind of like how your social media feed constantly refreshes to show you

97
00:04:55,760 --> 00:04:59,520
new posts. Exactly. Although the technical details are a bit different,

98
00:04:59,520 --> 00:05:00,720
the end result is the same.

99
00:05:00,720 --> 00:05:04,760
You get your messages as soon as they're sent without any noticeable delay.

100
00:05:04,760 --> 00:05:07,560
Okay. So we've talked about home servers, but what about the client?

101
00:05:07,560 --> 00:05:09,680
What exactly is that in the matrix world?

102
00:05:10,400 --> 00:05:13,960
The client is the software you actually use to interact with matrix.

103
00:05:13,960 --> 00:05:16,840
Think of it like your email app, but for matrix,

104
00:05:16,840 --> 00:05:20,080
it's what lets you log into your account, see your contacts,

105
00:05:20,080 --> 00:05:22,120
send messages and all that good stuff.

106
00:05:22,120 --> 00:05:23,800
So the client is the interface,

107
00:05:23,800 --> 00:05:27,520
the thing I actually see and use and it connects to my home server in the

108
00:05:27,520 --> 00:05:29,880
background to send and receive messages.

109
00:05:29,880 --> 00:05:33,200
What about these app services that the document mentions?

110
00:05:33,200 --> 00:05:36,280
They talk about bots and bridges. What are those all about?

111
00:05:36,480 --> 00:05:40,920
App services are basically extensions to matrix that add extra functionality.

112
00:05:40,920 --> 00:05:45,400
Bots are like automated users that can do things like post updates to a chat

113
00:05:45,400 --> 00:05:47,640
room or respond to commands.

114
00:05:47,640 --> 00:05:52,400
And bridges are super interesting because they connect matrix to other platforms

115
00:05:52,400 --> 00:05:55,640
like discord or Slack or even old school IRC.

116
00:05:55,640 --> 00:05:59,760
So if I'm using matrix and my friend is still on WhatsApp, for example,

117
00:05:59,760 --> 00:06:03,520
could we potentially chat with each other through a bridge?

118
00:06:03,920 --> 00:06:07,640
That's the idea. A bridge would create kind of a virtual representation of your

119
00:06:07,640 --> 00:06:09,560
friend on the matrix side and vice versa,

120
00:06:09,560 --> 00:06:12,680
allowing you to exchange messages even though you're on different platforms.

121
00:06:12,680 --> 00:06:16,480
That's pretty awesome. And finally, they talk about the matrix specification.

122
00:06:16,480 --> 00:06:17,360
What's that all about?

123
00:06:17,360 --> 00:06:20,160
The specification is like the rule book for matrix.

124
00:06:20,160 --> 00:06:23,920
It's a detailed document that describes exactly how all the different parts of

125
00:06:23,920 --> 00:06:27,200
matrix should work together. So it ensures that different clients,

126
00:06:27,200 --> 00:06:30,880
different home servers and different app services can all communicate with each

127
00:06:30,880 --> 00:06:32,160
other without any problems.

128
00:06:32,600 --> 00:06:35,840
It's like having a universal language that everyone in the matrix world

129
00:06:35,840 --> 00:06:36,680
understands.

130
00:06:36,680 --> 00:06:40,920
So even if I'm using a completely different matrix app than my friend and we're

131
00:06:40,920 --> 00:06:42,240
on different home servers,

132
00:06:42,240 --> 00:06:46,520
the matrix specification makes sure our messages can still get through to each

133
00:06:46,520 --> 00:06:47,520
other. Exactly.

134
00:06:47,520 --> 00:06:51,600
And the great thing is that the specification is open for anyone to read and

135
00:06:51,600 --> 00:06:52,440
contribute to.

136
00:06:52,440 --> 00:06:56,320
That means no single company controls how matrix works,

137
00:06:56,320 --> 00:07:00,240
which is a pretty big deal in today's world. Absolutely. So to recap for everyone,

138
00:07:00,600 --> 00:07:05,600
matrix is this open decentralized network for communication that gives you more

139
00:07:05,600 --> 00:07:08,600
control over your data and who you communicate with.

140
00:07:08,600 --> 00:07:11,640
You've got your home server, which is like your personal base station,

141
00:07:11,640 --> 00:07:16,840
your client, which is the app you use to chat app services like bots and bridges

142
00:07:16,840 --> 00:07:19,880
that add extra functionality and the matrix specification,

143
00:07:19,880 --> 00:07:21,800
which makes sure everything works together seamlessly.

144
00:07:21,800 --> 00:07:26,320
It's really a fascinating ecosystem and it offers a lot of potential for a more

145
00:07:26,320 --> 00:07:28,800
open and secure future of communication.

146
00:07:29,120 --> 00:07:31,200
And here's where it gets really interesting, right?

147
00:07:31,200 --> 00:07:33,440
Because matrix is decentralized.

148
00:07:33,440 --> 00:07:38,560
You're not relying on any one company to store your data or manage your connections.

149
00:07:38,560 --> 00:07:43,600
That means you have more control, more privacy and more flexibility and the

150
00:07:43,600 --> 00:07:47,760
ability to bridge with other platforms opens up all sorts of possibilities for

151
00:07:47,760 --> 00:07:50,600
connecting with people, regardless of what app they're using.

152
00:07:50,600 --> 00:07:54,680
It's a pretty compelling alternative to the centralized platforms that are so

153
00:07:54,680 --> 00:07:55,520
dominant today.

154
00:07:55,520 --> 00:07:58,960
Absolutely. And it really makes you think about the future of communication and

155
00:07:58,960 --> 00:08:02,720
the role that open decentralized technologies like Matrix might play.

156
00:08:02,720 --> 00:08:07,320
Definitely something worth considering as you make choices about the tools you

157
00:08:07,320 --> 00:08:09,000
use to communicate online.

158
00:08:09,000 --> 00:08:12,160
For sure. And with that, I think we've covered a lot of ground today.

159
00:08:12,160 --> 00:08:15,200
Hopefully this has given everyone a good understanding of what matrix is all

160
00:08:15,200 --> 00:08:16,920
about, even if you're just starting out.

161
00:08:16,920 --> 00:08:18,360
Absolutely. And of course,

162
00:08:18,360 --> 00:08:21,360
