Blockchains: Practical Approaches

Originally proposed for Bitcoin, Ethereum and other digital currencies, blockchain technology is now the most innovative framework for decentralized data management. This technology has not yet revealed its full potential to transform all economic and social processes. Its characteristics, interpreted and implemented in practice, are about to have their revolutionary impact on the possibilities for safe, fair and objective digitalization of the physical environment. The purpose of this paper is to present some general and specific aspects in research on applications of blockchain technology in intelligent agriculture. The main elements of the technology, popular definitions, focus areas in risk management concepts and the implications for internal audit and control procedures in companies that adopting blockchain in intelligent agriculture are briefly discussed. In summary, an algorithm for selecting of blockchain platforms and an algorithm for text mining in the domain of plant genetic resources are presented. A blockchain-based approach to modelling a supply chain in smart crop production is proposed, which is illustrated with a conceptual example of blockchain architecture and smart contract functions design. The future development of this study will focus on detailed analysis of existing blockchain standards, improving descriptions of functional levels in the supply chain network model and blockchain architecture design.
