Shvachych: ORCID 0000-0002-9439-5511ENG: This paper shows that information and communication technologies, particularly the digital economy, reveal a huge range of opportunities. It was noted that its strengths, the reducing costs, increasing the level of security, and transparency of transactions drew the attention of various economic sectors. In this regard, for a clear and definite understanding of the problems under consideration, the author's definition of the digital economy, digital technologies in the economy, and "end-to-end" digital technologies in the economy were introduced. The paper highlights the most intensively developing main components of the digital economy: distributed ledger technologies (blockchain) and real option technologies. Research has shown that blockchain technology is one of the main directions for the digital economy development. As a decentralized data registry, the paper shows that blockchain technology is the most discussed and relevant topic in the digital economy. Its strengths are analyzed, such as cost reduction, high security, and transaction transparency applicable to various economic sectors. The main mechanisms of contradictions, arrangement, and implementation of blockchain technology are detailed with the author's approach to eliminating the identified contradictions.endigital economy"end-to-end" digital technologiesblockchain technologydata storageКПМ та ОТThesis
