1 00:00:05,770 --> 00:00:08,200 Hello and welcome back to the course and blotching. 2 00:00:08,500 --> 00:00:14,400 So to understand what Web 3.0 is let's first understand what Web 2.0 is. 3 00:00:14,710 --> 00:00:21,370 Here we've got a couple of examples of Web sites back from the 90s as you might remember them or you 4 00:00:21,370 --> 00:00:24,500 might not remember them but this is what they looked like. 5 00:00:24,700 --> 00:00:30,970 And back then simply a Web site was just text. 6 00:00:31,000 --> 00:00:35,940 Maybe some images and some links and like in the case of Apple this is Apple upset. 7 00:00:35,980 --> 00:00:41,680 I was very upset and because of the Apple website like it's a bit like probably later in time or with 8 00:00:41,680 --> 00:00:47,190 more advice because you can see like a for me here some buttons and so on. 9 00:00:47,290 --> 00:00:52,630 Maybe like even some advance coloring and things like that. 10 00:00:52,780 --> 00:00:56,300 So yeah good old days. 11 00:00:56,370 --> 00:01:00,660 This is what the Web looks like and this wasn't Web 1.0. 12 00:01:00,940 --> 00:01:05,520 As you can see it's a very different experience to what we have now. 13 00:01:05,590 --> 00:01:09,030 So let's have a look at the Web sites of Apple and Amazon as they are today. 14 00:01:09,200 --> 00:01:10,650 There is Apple. 15 00:01:10,790 --> 00:01:13,020 You get those vibrant colors. 16 00:01:13,120 --> 00:01:22,540 We get all the menus at the top and how you can just go and watch a video right here of leaving the 17 00:01:22,540 --> 00:01:25,640 page and there is the Amazon Web site. 18 00:01:25,730 --> 00:01:29,730 Again you've got like a form here like a search form. 19 00:01:29,860 --> 00:01:33,820 You've got this carousel that's changing the ads in the background. 20 00:01:33,820 --> 00:01:41,410 There you go all these different other ads they're all tracking your purchases like you're you're being 21 00:01:41,410 --> 00:01:41,780 served. 22 00:01:41,780 --> 00:01:44,330 The most relevant things to you. 23 00:01:44,800 --> 00:01:51,640 There's always these Pop-Pop says is very interactive things and I'm not even talking about social media 24 00:01:51,930 --> 00:01:52,620 here. 25 00:01:52,630 --> 00:01:58,490 That's a huge new thing in the web as well compared to version 1.0. 26 00:01:58,500 --> 00:02:08,770 And so all of this together is called Web two point oh the term was popularized in 2004 and it signifies 27 00:02:08,860 --> 00:02:13,390 a paradigm shift in how we experience Web sites and the Internet. 28 00:02:13,390 --> 00:02:20,700 So we went from just basic text and links and images to everything moving around things. 29 00:02:20,700 --> 00:02:21,810 Loading. 30 00:02:21,880 --> 00:02:28,000 You can watch videos you can watch videos for adlibbing a page you can you you have social There's so 31 00:02:28,000 --> 00:02:31,110 many things going on and some of them are listed here. 32 00:02:31,100 --> 00:02:40,660 A big role in Web 2.0 was played by Ajax and or I-X and javascript's because those technologies allowed 33 00:02:41,050 --> 00:02:48,010 that whole transition to loading pages with refreshing loading elements on pages without having to refresh 34 00:02:48,010 --> 00:02:51,050 the page every time we've had the page refreshing itself. 35 00:02:51,250 --> 00:02:56,340 And that's that's immersion into your experience that you get from there. 36 00:02:56,610 --> 00:02:58,370 So that's Web 2.0. 37 00:02:58,480 --> 00:03:04,510 It was like a prize in 2004 is like a specific date when that happened it just it just kept happening 38 00:03:04,530 --> 00:03:07,590 and people realize that we're in a different world now. 39 00:03:07,870 --> 00:03:16,900 And so this map that out on a typical Web site or typical experience user experience of the web we have 40 00:03:16,900 --> 00:03:22,150 a front and the back in front end is what the user sees the back end is what happens in the background. 41 00:03:22,330 --> 00:03:23,250 What they don't see. 42 00:03:23,350 --> 00:03:30,900 So in terms of Front-End there is our back in Web 1.0 there is our app a Web site and now this is what 43 00:03:30,920 --> 00:03:39,910 looks like in Web 2.0 front and has changed drastically the whole experience has changed a lot not just 44 00:03:39,910 --> 00:03:47,590 what they see but like what they feel how how the machine learning technologies are serving and what 45 00:03:47,590 --> 00:03:54,550 videos they interact with how the Web sites remembering things they've done before and adapting to them. 46 00:03:54,910 --> 00:03:56,860 So that was that Web 1.0. 47 00:03:56,950 --> 00:04:00,000 This isn't Web 2.0 but let's get them back in. 48 00:04:00,010 --> 00:04:01,940 How does the back end change. 49 00:04:01,990 --> 00:04:04,130 Well Bakken hasn't changed much. 50 00:04:04,190 --> 00:04:09,940 We don't take into account all the complex algorithm that algorithms that sit in the back at the core 51 00:04:09,940 --> 00:04:18,100 structure and the core architecture of how people interact with Web sites and things on the web is through 52 00:04:18,200 --> 00:04:20,070 a centralized approach. 53 00:04:20,200 --> 00:04:27,120 There's a central server for instance Apple in this case the central server and we're accessing it. 54 00:04:27,130 --> 00:04:32,130 We're requesting things from a central server and then we're getting information back. 55 00:04:32,400 --> 00:04:39,820 And so this is where lauching can play a huge part in Web 3.0 and probably will. 56 00:04:39,820 --> 00:04:41,530 So there is Web 2.0. 57 00:04:41,710 --> 00:04:46,270 We don't really know what's going to happen with the front end because it's also important to think 58 00:04:46,270 --> 00:04:54,760 about that as well that that will change maybe it will become a computer vision or maybe will become 59 00:04:54,760 --> 00:05:00,750 like an even more interactive or even more AI driven personalized that things like that. 60 00:05:01,000 --> 00:05:03,630 That's not the question that we're answering here right now. 61 00:05:03,850 --> 00:05:06,530 The question is how will the back end change. 62 00:05:06,550 --> 00:05:14,410 Well this is where blotching play a major role and we can move from a centralized web in Web 2.0 to 63 00:05:14,410 --> 00:05:17,520 a decentralized web the Web 3.0. 64 00:05:17,810 --> 00:05:22,930 And let's have a look in a bit more detail how that can take place. 65 00:05:22,960 --> 00:05:31,260 So here we've got all the people in the world and as we know we're all interconnected. 66 00:05:31,630 --> 00:05:36,460 We all know something that somebody knows somebody and then people know each other and there's like 67 00:05:36,520 --> 00:05:44,830 this whole concept of Six Degrees of Separation and things like that or now it's the lower that you 68 00:05:44,830 --> 00:05:49,960 pretty much know anybody in the world through like four or five or six connections. 69 00:05:50,290 --> 00:05:55,000 But nevertheless even though we're all connected where we want to interact to each other what do we 70 00:05:55,000 --> 00:05:55,430 do. 71 00:05:55,450 --> 00:06:03,160 Well we go to for instance Facebook which has centralized servers which belong to Facebook and all the 72 00:06:03,160 --> 00:06:04,490 data is stored there. 73 00:06:04,540 --> 00:06:11,140 And so we are actually interacting with Facebook or Facebook's servers and services which then allow 74 00:06:11,560 --> 00:06:13,000 us to connect with each other. 75 00:06:13,000 --> 00:06:17,010 So we have that middleman Facebook which so far has done a great job. 76 00:06:17,010 --> 00:06:23,620 We've got we've got to give it to these companies that bring us closer together Facebook linked Twitter 77 00:06:23,620 --> 00:06:33,080 and so like they've they definitely had a major role in the evolution of how society and just globally 78 00:06:33,310 --> 00:06:34,900 the world is connected. 79 00:06:35,290 --> 00:06:42,280 However the core the underlying foundational premise of all remains that we are still interacting through 80 00:06:42,280 --> 00:06:48,620 a centralized way with each other through Facebook servers so they have control where data over our 81 00:06:48,620 --> 00:06:54,880 privacy they can service the ads they want to serve as they can charge us if they want to charge if 82 00:06:54,880 --> 00:06:57,960 they don't if they don't want to charge as adults. 83 00:06:58,000 --> 00:07:00,680 And so there is a lot of control. 84 00:07:00,680 --> 00:07:11,500 Are we giving away to them whereas in Web 3.0 with the block chain approach the hypothesized idea is 85 00:07:11,500 --> 00:07:19,810 that we move back to using this interconnectivity that we have with each other and at the same time 86 00:07:19,810 --> 00:07:26,630 they will be able of change or multiple block chains which would run the applications again a copy on 87 00:07:26,630 --> 00:07:34,300 this block chain would be stored on every single computer and then they would be smart contracts which 88 00:07:35,140 --> 00:07:41,650 govern how these applications work and what happens for instance in the case of a social media application 89 00:07:42,490 --> 00:07:43,800 or social media network. 90 00:07:43,820 --> 00:07:48,370 Smart contracts would say what happens when a person joins what happens when they add somebody as a 91 00:07:48,370 --> 00:07:48,880 friend. 92 00:07:48,880 --> 00:07:52,080 What happens when somebody posts something and so on. 93 00:07:52,080 --> 00:08:00,280 So basically the code behind that social media network and that would all be stored in a block channel 94 00:08:00,350 --> 00:08:07,750 shouldn't be running just as we discussed throughout this whole course how a watch chain works and a 95 00:08:07,780 --> 00:08:13,180 great example of Blash in readiness for this is theory serious blotching where applications are already 96 00:08:13,210 --> 00:08:19,950 created and we saw an example of steam in it which is a block chain version of Twitter. 97 00:08:20,530 --> 00:08:29,800 And so basically the social media network live on this block chain we would all have either our own 98 00:08:29,800 --> 00:08:34,530 data or fragments and bits and pieces of each other's data and then along the way. 99 00:08:34,720 --> 00:08:41,570 But the point is that the control over the data would be stored using a private key on the block chain 100 00:08:41,590 --> 00:08:47,020 so only you would have access to your data and you would through your interactions and through the smart 101 00:08:47,020 --> 00:08:52,870 contracts you would be able to and through your actions you would be able to select who gets to see 102 00:08:52,870 --> 00:08:56,470 your data doesn't who you want to be friends with who doesn't and befriend them. 103 00:08:56,530 --> 00:09:01,700 So you get control back over your data completely entirely because it's not stored on a centralized 104 00:09:01,700 --> 00:09:09,490 service store or near a computer again or there's other ways to implement this can be stored in fragmented 105 00:09:09,490 --> 00:09:13,180 pieces all over the place but only you can put it back together. 106 00:09:13,600 --> 00:09:20,770 And so therefore what we're doing is we're leveraging our own machines rather than a central server 107 00:09:20,770 --> 00:09:23,440 to help make all of this happen. 108 00:09:23,440 --> 00:09:28,260 All of the smart contracts are executing on all machines all the data is stored in our machines the 109 00:09:28,260 --> 00:09:30,460 block chain is running on our machines. 110 00:09:30,460 --> 00:09:35,680 The interconnectivity is happening between our machines we don't really need a central server. 111 00:09:35,860 --> 00:09:42,840 We can have a social network which is completely which doesn't belong to anyone. 112 00:09:42,840 --> 00:09:43,750 It just runs. 113 00:09:43,750 --> 00:09:52,090 It just exists and it's crowdsourced and people add to it and like take away from it and we all vote 114 00:09:52,120 --> 00:09:54,010 how it develops and things like that. 115 00:09:54,010 --> 00:09:56,610 So a very democratized approach. 116 00:09:57,970 --> 00:09:59,950 Where we all have control. 117 00:10:00,280 --> 00:10:05,890 So this brings us back to that idea of the supercomputer that Israel was trying to build like the global 118 00:10:05,920 --> 00:10:12,980 supercomputer using our little computers that we have rather than a centralized server. 119 00:10:13,990 --> 00:10:20,490 So there we go that's how Beauchesne can contribute to Web 3.0 very easy an example of this steam at 120 00:10:20,930 --> 00:10:21,490 a Web site. 121 00:10:21,490 --> 00:10:25,810 And there's more and facts and interesting additional reading for you here. 122 00:10:26,010 --> 00:10:26,690 Where 123 00:10:29,110 --> 00:10:38,110 author tio talks about the theoretical concepts and implications around ball or block chain or Web 3.0. 124 00:10:38,290 --> 00:10:46,030 Actually there is a screen shot there of the apps how they might change how the browser machine's storage 125 00:10:46,030 --> 00:10:49,180 and video call social networking and so on. 126 00:10:49,180 --> 00:10:53,380 So you actually see here steam it is over here. 127 00:10:53,620 --> 00:10:57,380 So there we go that's web three point onwards. 128 00:10:57,520 --> 00:10:59,810 And how blotching can play a role in that. 129 00:10:59,830 --> 00:11:08,080 Check out this article is quite popular on medium and yeah it's a good idea I think to get up today 130 00:11:08,140 --> 00:11:11,000 or upscaled with with what's coming ahead. 131 00:11:11,020 --> 00:11:15,490 What to expect from what the Internet will look like and why. 132 00:11:15,490 --> 00:11:23,110 Well because it will give you ideas on maybe how you can contribute to that or maybe how you can participate 133 00:11:23,110 --> 00:11:28,350 in all of this and get started early and start you know transitioning your mindset again. 134 00:11:28,420 --> 00:11:33,450 This is all just all might change in a few months in a few years. 135 00:11:33,450 --> 00:11:39,670 It might look completely different to what we're speculating now but it does look promising it does 136 00:11:39,670 --> 00:11:44,380 look like a very interesting way that world could go on that now. 137 00:11:44,410 --> 00:11:47,050 I hope you enjoyed this story on that look your next. 138 00:11:47,140 --> 00:11:48,320 Until then. 139 00:11:48,360 --> 00:11:49,000 But Cheyne's.
