description: The topic of the final qualifying work: âA distributed fault-tolerant system for collecting data from the blockchain networkâ. This work is devoted to the study of available solutions that solve the problem of collecting data from the blockchain network, comparing them and highlighting the shortcomings that we will correct in the process of developing our own data collection system. Tasks that were solved during the work:Examine some existing systems and highlighting their shortcomings. Development of a fault-tolerant distributed architecture. Development of the system based on the built architecture. Deploying the systemÂ As a result of the work, an architecture using a factor model was developed, which is well suited for our task. A distributed fault-tolerant system was developed in the Java programming language using the Akka library. The system was also deployed using Docker containerization and tested with tests that were built on dedicated cases
