The Alpha release is one of several next milestones for Nuggets. The company has promised to release an Android Alpha version in the coming weeks and integrate the payment function within months.

"Using blockchain technology, we’ve developed a platform that will revolutionise the way we store personal data and make transactions online,” says Alastair Johnson, the chief executive officer and co-founder of Nuggets. “Nuggets is all about giving consumers the chance to take back control of their data. Our Alpha offers the chance to become one of the very first people to do so.”

“We’re really looking forward to gathering feedback on the Alpha, and using that to show businesses how they can win back consumer confidence after the numerous data breach scandals of the past year,” he concludes.

So far, the platform has been opened up a limited batch of iOS users who entered a whitelist, with thousands of applicants already waiting to enjoy the perks of the alpha version. Accepted users will be able to download the Alpha, test the onboarding process, experiment with the login feature and provide feedback.
