Blockchain: Hype oder Innovation?

1. 00:00Welcome to the first week of our Blockchain courses on OPENHPI
2. 00:06Yes, it's happening now, and we want to think about the question, Blockchain, is that hype, is that innovation?
3. 00:13And we, that's my PhD student, Tatjana Gayvoronskaya and I, Christoph Meinel.
4. 00:19And this clip should briefly introduce the topic again.
5. 00:24This first week, we've set the course for two weeks, in this first week we want to introduce the topic Blockchain.
6. 00:33That's what we want with the help of statistics, we want to talk briefly about the history of the Blockchain technique.
7. 00:39We want to introduce, explain and define basic concepts. and also the approaches and technologies, that underlie this issue.
8. 00:50We'll get in a little bit. and take a look at the blockchain architecture, the various components,
9. 00:57the corresponding security architecture behind it,
10. 01:01We will discuss how it works and then at the end of the week.
11. 01:06an initial analysis of strengths and challenges when dealing with Blockchain then discuss.
12. 01:14You can find all this and much more in our study. We will make these available to you.
13. 01:22We'll put them at your disposal, and, of course, that's what it's gonna be about,
14. 01:27that there's a lot of information, that the topic is also relatively strongly polarized.
15. 01:33So from all the media coverage, there are very large investments in this area, for example in the area of venture capital for start-ups.
16. 01:43Large companies invest a lot, the first disappointments come to light,
17. 01:49that not all promises were fulfilled in such a way how you'd imagined it.
18. 01:54So there's a for and an against to blockchain technology, and that is precisely the intention of our course,
19. 02:02that we offer you so much information, that you can develop your own opinion on the subject.
20. 02:11That's it. If you look in the media these days, what do you see, what do you hear about blockchain technology?
21. 02:19Bitcoin loses or gains value. With Bitcoins you can pay in cafes, restaurants, anywhere.
22. 02:26Or, Blockchain can also improve authorities or even with crypto currency you can heat your own room.
23. 02:35You got that right, so you can with these crypto currencies, a lot of computing effort is necessary,
24. 02:40it generates heat, which can be used to heat the room.
25. 02:45And the energy industry, but also the oil industry, or automotive industry, logistics,
26. 02:53all use blockchain technology, and successful.
27. 02:57And such issues as identity management, such as storage, like Exchange, like gambling or presidential elections,
28. 03:07everything is possible with Blockchain.
29. 03:09Even such an industrial giant as Amazon would also like to offer Blockchain as a service for the developers, so that everyone can develop and use it.
30. 03:21And, of course, the whole thing leads to it, you have to think about it, is this some kind of hype?
31. 03:26That's it. Or is Blockchain an all-purpose weapon?
32. 03:30Gartner is a consulting firm from America and also makes its own statistics on new technologies such as "Hype Cycle for Emerging Technologies".
33. 03:41And here we can also see Blockchain in 2016.
34. 03:46Maybe very briefly, that's always the curve, when an innovation begins to gain popularity.
35. 03:52Here, this phase is then the peak of expectations, inflationary expectations.
36. 03:59Typically, here comes the valley of disillusions, of disappointment, and then, slowly the value becomes, the value oscillates, the actual value then in productivity.
37. 04:13Where is Blockchain now, 2016?
38. 04:16So Blockchain in 2016 lies just before the peak of exaggerated expectations, and already in 2017, it will go down into the valley of disappointments.
39. 04:27This means that Blockchain still has no standards, no interoperability.
40. 04:31And that's why many are disappointed. A lot of people try that, but it doesn't all work out the way you expected.
41. 04:39But of course, if there are the standards, then the technology can also be sustainable.
42. 04:45If you take a look what's going on in Germany Bitkom - that is the industry association of the digital industry -
43. 04:52what Bitkom expects, here, what status there of blockchain technology,
44. 05:01then here the 26 % are for a rather young technology is already a very strong value.
45. 05:09Here something like IT security, cloud computing, of course, that's been in the country for a while now,
46. 05:14but this blockchain technology is one of the most important trends, and so it's important and right, that you want to take your time to get deeper into it.
47. 05:25That's it. And when we see that, it gives us hope, it's an innovation, isn't it?
48. 05:31See for yourself.
