This document describes a new platform called Blue Catalyst that Capgemini and R3 are bringing to market. Blue Catalyst is a distributed blockchain-based platform that enables consent-based sharing of sensitive customer and supplier data to streamline onboarding processes. It allows each legal entity to own and control a digital vault of information and securely share data with consent. This improves traceability, reduces duplication of efforts, and helps ensure compliance with regulations. Use cases discussed include know your customer (KYC) and know your supplier (KYS) onboarding as well as opportunities in supply chain finance.
