Blockchain technology can completely transform sports, including athlete smart contracts and data management, fan interaction, betting, ticketing, and legitimacy. It can make safe, clear ticketing processes, authenticate sports collectibles, and establish fan loyalty programs. Athlete contracts and payments can be automated via smart contracts, and blockchain-based loyalty schemes can potentially reward fans with digital tokens. Blockchain technology can enhance sports in terms of player identity, scouting, performance, and dynamic price. Though more creative uses are starting to emerge, general adoption is still in its early stages, despite its promise. With this background in mind, a survey was created based on earlier research approved by an ethics commission to examine sports experts' perceptions of the advantages of blockchain in sports performance. Through the use of SEM Smart PLS and a cluster analysis, the research validated the hypothesis that in Romania the implementation of Blockchain Apps in sport fosters trust in blockchain benefits and improves the national and European athlete performance.
