NFTs means the future value of art is zero

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 […]

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 praise of slowness


A digital watch.

Sometimes - only sometimes - slowness is a feature, not a bug. A few weeks ago, I was reading about a purported use for "smart contracts". If your plane is cancelled, a smart-contract could automatically pay out your travel insurance, the millisecond the cancellation was reported. Nifty, right‽ Slowness for crap reasons There are plenty […]

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 […]

As with any […]

And now it's… Springtime For Crypto


Still from the movie "The Producers".

You've heard of the AI Winter, right? The period where funding for AI dried up due to products failing to meet their hype. I think we're now in Springtime For Crypto1 - named after the musical "Springtime for Hitler" from movie The Producers - where scams abound. You should take a couple of hours to […]

Thinking of uses for BlockChains

Kevin Kelly has written an insightful blog post about Class 1 / Class 2 Problems. I encourage you to read it. I agree with the thesis, but not the specific conclusion. Blockchain tech could unleash collaborations of several million members working on one project in real time, or orgs that are far more leaderless than […]

A weird solar blockchain thing - Rowan Energy


Using Blockchain to encourage green energy is not viable due to the incredible amount of energy it takes to mine transactions.Our blockchain is a POA (proof of authority) blockchain that is designed to run on ultra lower powered devices. The devices are in the home of our supporters and take only about $10 per year to power.

I blog about my solar panels - probably a bit too much! Recently, a reader asked me if I'd heard of Rowan Energy's solar payback scheme - so I took a look into it. Here's how it works: Rowan installer a "miner" next to your solar inverter (the big box that turns DC from solar […]

What happens if you steal someone's Good Tweet™?


Fraud alert warning signs.

Way back in the early days of the Social Web, the writer Cory Doctorow invented Whuffie. Think of it as a way to formalise "upvotes" and "likes" on social media. Whuffie, a form of digital social reputation, replaces money and is a constantly updated rating that measures how much esteem and respect other people have […]
