Enhancing Payment Authentication and Security for Sports Facility Booking Using Blockchain Technology

The research investigates crucial difficulties in sports facility booking platforms that stem from payment security issues along with authentication weakness points. The conventional booking systems experience difficulties including payment frauds and data breaches together with unclear transaction records. Our blockchain security solution targets sports facility booking applications to resolve the current security challenges. A combination of smart contracts alongside decentralized authentication and cryptographic security components improves payment integrity according to our framework. The system uses collective Ethereum smart contracts together with Flutter graphical elements linked to Firebase database systems for back-end operations. Our blockchain framework on LineUp shows superior security strength through comparison with traditional security paradigms. The research which does not reveal statistical data has achieved substantial security improvements in booking transactions for sports facilities while creating better user trust and fewer payment fraud cases and operational performance enhancements for digital sports bookings.
