Could blockchain unlock the potential in IoT?

Much hyped blockchain may help bring desperately needed security to IoT

There aren’t many areas where blockchain isn’t tipped for success.

Blockchain is most famous for being the virtual ledger that records bitcoin payments, but outside of this specific cryptocurrency, its strength comes from its ability to keep data transactions accountable. “Blockchain computer technology has the potential to create an open and shared platform that billions of devices can use to interact,” explains Shaan Mulchandani, director of technology and security at engineering company, Aricent.

“One day an autonomous car might use the blockchain both to accept rental payments and to pay a pump for gas. Clearly such infrastructure needs to be secure as well as open, and blockchain can provide this too,” he says.

And this is why it may come into its own with the Internet of Things.
