Blockchain technology is revolutionizing the sports industry by enhancing fan engagement, digital collectibles, and monetization opportunities for athletes and teams. Blockchain-based platforms enable fans to purchase and trade digital collectibles (NFTs) representing moments, jerseys, and memorabilia from their favorite athletes and teams. Smart contracts automate royalty payments and fan rewards, empowering athletes and content creators to monetize their digital assets and engage directly with their fan base. Projects like NBA Top Shot and Sorare are transforming sports fandom through blockchain innovation.
