The UK government is exploring the possibility of using blockchain technology to improve the accuracy and transparency of its recordkeeping.

In a blog post, Paul Downey of UK’s Government Digital Service explained how his team has been looking at ways to they can improve registers, possibly with blockchain.

“We’ve spent a lot of time looking at a large number of such lists, and what’s become apparent is that they’re all held and maintained quite differently,” Downey wrote. “That causes problems.”

Currently, the government has three different kinds of registers: open registers, which contain public data; closed registers that will ask users to pay a fee or provide a token before accessing the data; and the private registers that contain sensitive information.
