COMPARISON OF BLOCKCHAIN TECHNOLOGY AND DIRECTED ACYCLIC GRAPH DURING DATA STORAGE AND PROCESSING IN A DISTRIBUTED REGISTRY

Abstract

The technology of distributed registry, which revolutionary approach to recording and exchanging data between multiple data warehouses, is considered. The key features of distributed registry technology are highlighted and described. Particular attention is paid to blockchain technology and a directed acyclic graph. The principle of the operation of blockchain technology is described. All stages that go through transactions before they are added to the blockchain are graphically presented and described. All the main advantages of blockchain technology are described, and key network disadvantages are also presented. In describing the limitations of blockchain technology, real information was presented that confirms the existing flaws of this technology. Thanks to the optimized consensus mechanism, high scalability and the ability to carry out microtransactions, the technology of a directed acyclic graph is rapidly developing. The principle of operation of a directed acyclic graph is described and how the digraph differs from blockchain technology. The main advantages of a directed acyclic graph are described, which the digraph inherited from the blockchain and improved due to its structure. When comparing registers based on a directed acyclic graph and blockchain, interesting aspects of platforms can be identified. Despite the obvious similarities between paradigms, differences also persist. Based on the results, it becomes apparent that the future of distributed ledger technology is huge. Since a directed acyclic graph, due to its structure and advantages, has already overshadowed the blockchain architecture. The appearance of a directed acyclic graph will allow distributed registry technology to be introduced into all areas of activity on a global scale.
