I am massively sceptical of any claims that Blockchain can be useful. I even took the Certified Blockchain Professional course so I could better understand the batshittery. At the risk of appearing on QTWTAIN, and seeking a papal indulgence from Betteridge, I think I might have stumbled on a retroactive use-case for Blockchain! First up, what is LIBOR and what was the scandal which led to…

A few weeks ago, someone wanted to send me some crypto. After spending months studying for a Blockchain exam, I usually avoid such things. But, hey, $20 is $20. So I signed up for a wallet, installed an extension, verified my credentials, saved a seed phrase, and - without too much technical fuss - had some crypto transferred to my account. So far, so good. Compared to a traditional financial…

Dear the venture capitalists. I am a very charming white man and am prepared to drop out of university if you'll invest in these ideas. In the future, all your clothes are an NFT. "Wow!

Wouldn't it be good if digital currencies worked offline? I'm going to talk through a proposed user experience, and then discuss how it would work in practice. Let us imagine a future digital currency ₢. It might be fiat, it might be crypto, doesn't really matter. Alice loads up a smartcard with ₢100 and locks it. Alice gives Bob the smartcard. Bob uses offline verification to see that the sma…

I was at an event a few months ago, where someone from the Bank of England was talking about understanding the user needs for cryptocurrency. One of the things people do when trying to create a new product or service is to write little user stories to illustrate the problem they're solving. You've probably seen this sort of thing: As a… busy parent, I want… a push alert from my washing mac…

I'm doing an apprenticeship MSc in Digital Technology. In the spirit of openness, I'm blogging my research and my assignments. This is my final assignment! It's from the PP2 module - where I take some CPD related to my profession. I picked Blockchain. Because I hate myself. I've blogged about the course itself. The middle two parts of this paper are about that - why I chose it and how I put it …

As previously discussed, I'm doing the Certified Blockchain Professional course. It is self-directed learning, so I'm going through it at my own pace. In order to consolidate my learning, and help organise my thoughts, I'm blogging about my reflections on each module. These are mostly notes to myself - but I hope if you find something interesting (or incorrect) that you'll leave a comment. The…
