The national banking group of South Korean banks will launch a customer ID verification powered by blockchain technology in July. The new “BankSign”, is a blockchain-based identity verification platform that will enable retail domestic banks to improve a 20-year old verification system with digitization in both online and mobile banking. The platform is built on on top of Nexledger, a private enterprise cloud computing platform developed by Samsung SDS – the IT subsidiary of South Korea’s biggest conglomerate, Samsung.
