Feniks.Finance is a new financial blockchain based system, created on a fundamentally new concept, capable of scaling its speed as needed and adding new functionality. Feniks. Finance can be used as an international banking system for information transfer and payment execution. The first version of Feniks.Finance will be able to handle payments and storage of users' funds. Namely, the banking transactions labeled in the SWIFT system with MT103 as payment sent and MT202 as a receipt and crediting of the payment to the account. The next step in the development of the system will be a 700 group of SWIFT operations, namely documentary transactions better known as guarantees and letters of credit. The introduction of the 500 group, that is, the operation with securities, suggests that an exchange will appear in our network. The technical characteristics of Feniks.Finance will be decisive, as none of the solutions we studied can in fact provide the speed of 50,000 transactions per second, which are necessary in order to create real competition with the current financial and payment systems.
