Optimized and Dynamic KYC System Based on Blockchain Technology

Systems that use blockchain technology to improve the know-your-customer (KYC) process have only been proposed at a conceptual level and all share certain attributes that make their adoption by financial institutions (FIs) very difficult. We propose and program a blockchain-based system that reduces and shares out among the financial institutions that work with a customer the costs of the KYC process and also makes it possible for FIs to dynamically update information related to customers and disseminates this information among participating FIs. Additionally, our system addresses some of the attributes that hinder the adoption of previously proposed solutions by FIs. The result is a programmed, stand-alone solution that can be implemented by FIs to reduce the cost of the KYC process without requiring any central instance to store the customer's data, and in which FIs share the initial costs of the KYC process as well as the running costs of keeping the information about customers up to date. Our system increases the levels of security and regulatory compliance in the KYC process and significantly reduces the cost of that process for all parties involved
