Blockchain making houses safer
-
Blockchain technology developed to guarantee the value of cryptocurrencies such as Bitcoin and Ethereum is now being adopted by engineers as a way to fight off the risk of a hacker breaking into the connected appliances of today’s smart homes.
In recent years, domestic appliances smart enough to automate tasks ranging from ordering Christmas gifts to turning on thermostats have spread to millions of homes across Europe.
Puzzle
'Blockchain is a piece of software that essentially crowd-sources oversight,’ said Augusto. ‘It works by giving lots of computers one piece of a puzzle that can only be solved as a joint effort.’
Whereas cryptocurrencies use blockchain to check that no two people spend the same coin, the GHOST project is adapting the software and exploiting it to make sure that no outsiders tamper with the list of cyber threats hosted on its gateways.
GHOST partners have designed their gateways to record encrypted information on all other gateways in their network. To trick the blockchain, a hacker would have to commandeer half the machines in the network.
