Blockchain: cut the cryptocurrencies and taste the tuna

Cryptocurrencies based on blockchain technology, such as bitcoin and ethereum, get a lot of hype. Some believe they are the future of finance, while other including savvy MPs on the Commons Treasury Committee and the Financial Times’ Alphaville blog (free registration required) take a more cynical view. Recent drops in the price of bitcoin suggest the latter have a point.

Like many technologies, blockchain – which creates a permanent, unalterable record of transactions – may prove to be of greater use in areas other than its original one. I have previously looked at its uses outside finance for Computer Weekly, but have now focused on how it can support food and drink supply chains.

The profit-loss divide on a decade’s house prices

Land accounts for 51% of the UK’s total net worth of £10.2 trillion, far more than in France (42%) or Germany (26%). Most of this, £4.1 trillion, is the value of the land our homes are built on – the buildings are worth a further £1.8 trillion.

From 2009 to 2017, the Office for National Statistics reckons that land held by households has risen by a compound annual growth rate of 5.9%. But that disguises huge local differences. I compared the latest June 2018 data from the Land Registry’s House Price Index to that of a decade earlier, and found that in 42 of the UK’s 217 top-tier local authority areas house prices have actually fallen in cash terms over the decade. They are marked pink and red on this map.

Cancer diets and tech giants: having cake and eating it

I recently worked with Jack Malvern at The Times on a news story on ketogenic diet apps that claim to help treat cancer (subscription required).

A ketogenic diet, which is very low in carbohydrates, can be used under medical supervision to treat children with epilepsy. But Cancer Research UK says there is no evidence it is effective in reducing the risk of people getting cancer or increasing survival rates.
