Since the introduction of the Bitcoin solution, decentralized and distributed solution techniques have significantly evolved. Techniques such as Hirected Acyclic Graphs (DAG), Hashgraph, and Holochain, encompassing blockchain technology, have begun to be evaluated under distributed ledger technologies and applied in nearly every field. One of the extensive application areas of distributed ledger technology is the sports industry, which can benefit from its capabilities in numerous areas, including athlete data management, sports event management, and the financing of sports. In this study we propose methods based on NFT and Ordinal Theory that can be used in athlete data management, sport event management, sports collectibles and products, and sports copyright protection. Sample tests were conducted for both methods, and the results were compared.
