Blockchain technology has the potential to revolutionize the sports industry by enhancing athlete data management, automating smart contracts, improving ticketing security, and fostering fan engagement through innovative loyalty programs. Though more creative uses are starting to emerge, general adoption is still in its early stages, despite its promise. This study explores the impact of blockchain applications on team sports performance in Romania, focusing on their perceived benefits and applicability. A survey, validated by an ethics commission, was conducted among sports professionals to assess these impacts of technology on performance. For data analysis we have done a Structural Equation Modeling (SEM) with Smart PLS and a cluster analysis in SPSS 22.0. Results indicate that blockchain benefits significantly influence the adoption of blockchain applications, which, in turn, positively impact athletes’ performance at national and European levels. This study identifies key factors contributing to the implementation success of blockchain apps in sports and offers insights into the technology's broader potential for fostering transparency, efficiency, and competitive growth in the sports industry. This 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.
