The complexity is the attraction - reflections on trying to use crypto


A fiver and some coins on a table.

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 […]

What is the user need for cryptocurrency?

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 […]

Certified Blockchain Professional - Module 05: Sustainable Blockchain


Logo for the Certified Blockchain Professional.

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 […]

Transferable Bank Accounts

Here's a (possibly) daft idea. What if you could pay for goods using a transferable bank account? Say you want to pay a friend some money. But you're not physically close enough to hand over cash. You create a new bank account with a unique username and password. As quickly and easily as getting a […]

Review: BitCoin Hurricane (SimCavalier Book One) by Kate Baucherel


A bitcoin network visualisation.

Everything that BitCoin and BlockChain touches is poisoned. Except for this fun wee book. It's a near-future sci-fi cyber-heist with a great cast of characters and some delicious predictions about how the Internet of Things could go disastrously wrong. Thankfully, there's very little technobabble. I nodded along with most of the technology - only pausing […]

Advertising Screens Hacked To Mine BitCoin


The display shows a windows desktop with a variety of icons. There is a window open

Spotted in London, yesterday. A large, Microsoft Windows-powered advertising hoarding has been hijacked. It's not uncommon to see broken-down Windows displays - I run https://windowsisbroken.tumblr.com/ - which is dedicated to pointing and laughing at such mistakes. But this is the first time I've seen a display repurposed for profit! It appears to be running NiceHash […]

A QR Specification For Mobile Payments


BitCoin and other crypto-currencies are gaining popularity at the moment - but I remain firmly convinced that they're too hard for the average person to use. I have, however, watched with interest as an ecosystem grows around them. In particular, I like the way The Pirate Bay (and others) have used QR codes to facilitate […]

How To Steal A Million Dollars?


A fiver and some coins on a table.

... as our money becomes completely electronic, new crimes will undoubtedly be committed which take advantage of the technology itself. Perhaps if we could imagine what crimes might happen, we could start to think about how to prevent them. What financial crimes could be committed within a completely electronic marketplace? Future of Money Design Award […]

Bitcoin Sucks - But It Doesn't Have To!

Bitcoin me! 1LJmePYmet9VjpeAqqLbdRRVGoYcLqAZhk If that "sentence" makes any sense to you - you're not a muggle. Muggles (for want of a better epithet) don't want to invest a lot of time into things which don't fit with their mental model of how the world works. Without getting into a philosophical discussion on what money is […]
