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. Where and how will blockchain revolutionise industries? Another hopelessly optimistic chapter. Can…

When I was young, I had a piggy bank. A piggy bank is incredibly secure. It's fairly big - so it is hard to lose. It is brightly coloured - so you can find it easily. No one else can see how much money there is in there. The only way to get money out is to smash it - providing visible evidence if someone has robbed you. And smashing makes a noise - deterring would-be thieves. A piggy bank is close to perfect security. If you are seven and your adversary is a younger sibling. Storing your own …

Let's assume that I'm correct and, through a combination of technology and changing social attitudes, no one wants to pay for music, books, films, or art any more. What are the ways that art and artists could get funded? Here are a few sketched out ideas - they all overlap a little. And then a brief discussion about how…

At the moment, it is not possible to sell a 2nd hand eBook or MP3. This seems fairly reasonable because a re-seller might keep copies of their original files after selling them. This would allow the re-seller to undercut the original publisher and sell the file multiple times. We tend to label this "Piracy". Someone buys a DVD, rips it, then either sells or gives away copies. The Blockchain book that I'm reading suggests NFTs as a way to combat this (stop giggling at the back). Let's say…
