Situational digitalization of commodity-money circulation

A model of situational digitalization of the commodity-money circulation system is proposed, where the specifications of goods, payments, and other components of the system are represented by encrypted digital codes. The management of commodity-money circulation is carried out through the systems of mandatory and orienting requirements fixed in situational digital contracts that determine the relationships between customers and suppliers. The implementation of each contract is represented by the situations defined there. Data defining the portraits of situations are supplied by digital twins serving the contract. These data are going to the input of the contract program executed on the computer devices of the contracting parties. The movement of goods and payments is accompanied by the documentary supported movement of the corresponding codes. Each operation is reflected in the memory of the digital system of recording the values of property rights, represented by a set of unified accounts of suppliers and customers. Multicurrency accounts are opened and programmatically controlled by the online services of the regulating bank. For each commodity, the transaction can be made in any currency from the list which is the intersection of the sets of currencies allowed by the regulating banks of the states to which the transaction parties belong.
