Dave Hudson



Welcome to my (Dave Hudson’s) space on the Internet.

I collect things I find important under “Elements".

If something gets my attention, and I have time, I like to write Blog posts. When I started the site I wrote a lot about Bitcoin mining, hence the site name. I’m still very much active in the world of distributed ledgers and blockchain, but am a less active observer of cryptocurrencies now.

A long time ago I discovered I needed to keep track of things I’m doing. My latest experiement in this is the “Journal". The journal is just somewhere for me to think aloud - it’s definitely not definitive!

Blockchain is a new technology, but we've seen new technologies before. In the 1990s, the Internet of Things (IoT) was going to change the world, but it didn't work out quite the way we expected it to.
