Blockchain Based Customer Intelligence Sharing – (Rizico) Qorus Banking Innovation Awards 2021 - Winner

Blockchain technology, whose popularity has increased rapidly today, has started to be used frequently in the financial sector. Vakif Participation Bank's R&D Center has accumulated knowledge on this technology with various research studies and project ideas have been developed on issues where inadequacy in the current technology has been identified. One of the most fundamental issues of banking is the collection of loans, and the first condition to ensure that loans are collected without delay is to provide the right loan to the right customer. During the credit evaluation phase, the most critical data that will shed light on the allocation authorities are obtained through intelligence inquiries. Intelligence data is usually obtained from central institutions such as the Risk Center and the credit bureau. However, the data provided by these authorities cannot currently meet all the needs. In this study, limit, risk and collateral information, which is the subject of intelligence, will be shared with banks thanks to the blockchain infrastructure. A bank adds the intelligence information of a customer to which it has made a loan in detail in the appropriate format, to the blocks in the blockchain network. This data is instantly visible on other networks. If this customer wants to work in another bank, he can access this information by being included in the blockchain network. In this context, every bank that wants to access intelligence information is also expected to be a network that provides data. The sum of the intelligence information added by each bank is made available to all banks involved in the blockchain network. This total data is kept synchronously on each bank's side separately.
