The world has not yet come up with a single recipe for fighting corruption. But thanks to constant progress, anti-corruption strategies are replenished with effective innovation mechanisms. The global experience of using blockchain opens up new prospects for eliminating corruption in the world. Blockchain is an opportunity not only to modernize outdated functional systems, but also to apply new, more effective means of combating corruption and cybercrime. One of the main advantages of the blockchain is that all network participants have a register of transaction data. Therefore, if someone decides to hide, delete or change their recalculations in the accounting book, then copies of these transactions still remain in tens of thousands of other users and the system immediately accesses them. Therefore, a few minutes will be enough to solve the issues of detecting a crime. Today, it is worth highlighting 3 types of widespread use of blockchain technology in the fight against corruption: identity verification, asset registration and tracking of monetary transactions. For example, you can check the purpose of money transfers in real time, see salary payments, and compare prices among suppliers. Like any type of crime, corruption in human society cannot be completely excluded. However, decentralized platforms functioning on blockchain technology, already today, firstly, can directly bring together the customer and the executor, and secondly, all the conditions agreed upon by the participants can then be easily verified (thus, it will be impossible to imperceptibly inflate the price when using blockchain). Blockchain technology is in demand because it creates an unprecedented degree of trust in information in relationships between individuals and public organizations, or between the state, people and private institutions.

The DDS middleware provides powerful support for data dissemination in the distributed real-time and embedded (DRE) systems, and supports multiple transport protocol (e.g. TCP, UDP and Multicast) that affect the end-to-end quality of service (QoS) properties (e.g. latency, jitter and reliability).In order to evaluate the performance of the transport protocol and then evaluate the affection on the DDS middleware QoS, this paper first briefly compares the common DDS implementations, and then presents performance evaluation and analysis of the transport protocol in OpenDDS with different environment configurations, at last presents the conclusion.

Refining and petrochemical processing facilities utilize various process control applications to raise productivity and enhance plant operation. Client–server communication model is used for integrating these highly interacting applications across multiple network layers utilized in distributed control systems. This paper presents an optimum process control environment by merging sequential and regulatory control, advanced regulatory control, multivariable control, unit-based process control, and plant-wide advanced process control into a single collaborative automation platform to ensure optimum operation of processing equipment for achieving maximum yield of all manufacturing facilities. The main control module is replaced by a standard real-time server. The input/output racks are physically and logically decoupled from the controller by converting them into distributed autonomous process interface systems. Real-time data distribution service middleware is used for providing seamless cross-vendor interoperable communication among all process control applications and distributed autonomous process interface systems. Detailed performance analysis was conducted to evaluate the average communication latency and aggregate messaging capacity among process control applications and distributed autonomous process interface systems. The overall performance results confirm the viability of the new proposal as the basis for designing an optimal collaborative automation platform to handle all process control applications. It also does not impose any inherent limit on the aggregate data messaging capacity, making it suitable for scalable automation platforms.
