The architecture of BRICS Pay envisions a more centralized structure within individual countries while maintaining a decentralized approach on an international scale. High-speed deployment, scalability, decentralization, and interoperability are achieved through the creation of distributed networks for transmitting both payment information and liquidity.
The system's core topology is a decentralized star-topology, represented as a connected graph with subgraphs—payment networks within each country. Participants in the settlement system can connect to various vertices (nodes) of transactions. These subsystems (subgraphs) represent existing or prospective payment systems, with local settlement banks located at the centers of these subgraphs. Each country may have multiple such banks. Additionally, within the implemented topology of BRICS Pay, participating banks can establish direct relationships with other foreign banks or another financial institutions.
