Blockchain (Part 1)
Blockchain technology is a distributed ledger. It allows for the permanent and immutable
transparent recording of data, essentially, and transactions specifically. That can be used to
exchange any number of things that have value, whether thatâs an actual item [or
something else]. It could be tea leaves making their way to the final tea maker. Or it could
be me sending you a payment person to person without the need for intermediaries.](https://image.slidesharecdn.com/chicagofinfads-180815195841/85/Technology-fads-Weighing-risks-and-benefits-17-320.jpg)

Technology fads: Weighing risks and benefits
The document summarizes Martin Walker's workshop on fads in information technology. It discusses how new technologies and methods are often labeled as magic or revolutionary before their true impacts and limitations are known. It provides blockchain, agile development, and digital transformation as examples of concepts that have been adopted as fads in some cases. The document emphasizes the importance of questioning new solutions, understanding the problems they aim to address, and having evidence that they are better than alternatives rather than blindly trusting proponents of new technologies.

Editor's Notes
- #3Â IT and many forms of technology can seem like âmagicâ to the non-technical because they do amazing things, most people do not understand how they do amazing things and If they do amazing things reliably they donât need to worry how they work
- #4Â Yes magic. I want the simple solutions to all my problems, just like the Smart phone simply solves the problem of what to do while eating dinner with your spouse Non-technical people want Technology solutions that hlpe then make more money, cut costs etc. Technical people are just as keen to here about the latest technologies and how they will solve all problems
- #5Â IT and many forms of technology can seem like âmagicâ to the non-technical because they do amazing things, most people do not understand how they do amazing things and If they do amazing things reliably they donât need to worry how they work
- #6Â First interaction. Lets learn some magic words to defend against the dark arts of out of control costs, corrupt middle men, limits of human reasoning ability. How has heard of at least some of the above? Hands up. Keep them up if what you have heard about them is amazing. Keep your hands up if anything has satisfactory explained to you either how they work or even how they solve problems. Thank you hands down.
- #7Â These are some old magic words, which have lost some of their power. The power of many of the new magic words is based on them being better than the old magic words. Any volunteer willing to explain why an App or a Smart Contract is better than a programme?
- #8Â Now do believe in the magic of IT. There is a magical quality in nature of computers, programming tools and the software created. They can be used for anything..
- #9Â Big But. You need people. This is why IT can simultaneously be amazing and hugely disappointing. If you have worked in IT for a few decades you will have noticed cycles of enthusiasm and deep cynicism. Poor old programmers seem to have their role re-named every few years to make it sound more exciting during the hype cycle. Programmer not exciting enough, you are now a developer Not cool enough, you are now a âcoderâ and since you are now a coder you have better grow a beard and get me a flat white.
- #10Â During the hype, everything is great, everything is an advance making things, quicker, faster, cheaper, Every new idea is a good idea, regardless of whether it is really new, really good or even really an idea as opposed to a vague feeling progress is relentless and you have better not get in its way.
- #11Â The rest of the time everything sucks. We seem to have reached an interesting point where everything labelled as innovative and disruptive and everything else sucks.
- #12Â So can the non-technical world question new innovative/disruptive ideas while being a little more objective about the other IT stuff? Not always easy to ask questions from any technical specialist but you have to because non-technical people are continually being asked to make decisions relevant to IT,
- #13Â In the periods of hype, there is not just the technical/non-technical barrier, there are armies of people whose role is stop you asking questions. Some are the genuine enthusiasts who genuinely believe in new technologies, often a touch too religiously and sometimes devoid from any real-world context. Then there are large number of people making a great deal of money selling and propating hype. Many of whom have little idea what is they are selling. 100,000 thought leaders on Linked
- #14 Step 1- I am going to making you into more an expert on computing than the typical thought leader in 5 minutesâŠThese are the magic words are going to learn First lets talk about them in the abstract, then lets talk about pancakes
- #15 So you can think of the inputs as ingredients The algorithm as a recipe The processing, following the rules of the algorithm as the cooking The pancake as the output What data is there⊠Well that where the digital and physical worlds diverge a little. Data doesnât get used up. It can be deleted (even from a Blockchain) so lets The inputs are data, the outputs are data, and even the algorithm can be thought of data.
- #16 Now you are a computing expert, we move onto the typically questions you really need to ask both yourself and others. You will notice they are basically the same questions from Evidence-Based Management So now lets try using themâŠ
