The role of blockchain for increase trust on software components and services

Software components and services are the main building blocks for distributed software projects, enabling them to make software engineering really global. However, the trust for binary components or service is still an open question. Because the components and services are provided to the system without the possibility of the detailed inspection of its internals, global system integrators are walking on edge to approve such building blocks inside the system. In the times when software quality now is critically important (as the financial data), we need solutions as secure as those which are used to preserve financial data. In this paper, the authors discuss the main issues of the software components and services trust and to present the blockchain-based model of software metadata registration and retrieval to increase the trust for the software composition entities.
