Abstract: Decentralized computing and blockchain technology play a significant role in the implementation of modern digital economy business models. The most noticeable trends in this economy are the diversification and convergence of platforms and services, which is often achieved through undesirable fragmentation of the overall IT landscape. Business solutions represented by different blockchain networks turn out to be poorly connected, data exchange between them is difficult. The search for ways to overcome barriers between different decentralized networks leads to an increase in the importance of cross-platform integration solutions, providing the necessary level of interoperability. Such solutions must be secure both in terms of confidentiality and fault tolerance. Below is a vision of the architecture of integration gateways using the ODAP-2PC protocol, which provides crash fault-tolerance for the integration of various networks. This architecture provides transparency of interaction, reliability and continuity of audit in digital asset exchange systems or payment systems with increased requirements for interoperability.
