Cambridge Blockchain has developed a world-class digital identity and personal data sharing product based on a combination of leading information system technologies and emerging enterprise blockchain technology. The Cambridge Blockchain solution brings massive efficiencies to enterprises for B2B and B2C applications by creating strong, reusable digital identities and enabling user-controlled, privacy-protecting and regulatory-compliant sharing of personal data. Our product is a distributed application deployed in a microservices framework and incorporates a blockchain component based on smart contracts. Cambridge Blockchain is currently piloting and developing the solution for two applications, (1) a B2C application that allows businesses to rapidly engage with customers while remaining in compliance with data privacy regulations, with a large European trust services provider and, (2) a cross-border customer onboarding application for a global European bank. Both these applications represent a class of unmet needs critical to streamline the functioning of a large, increasingly digital economy.
