Blockchain technology is transforming digital transactions by eliminating intermediaries, enhancing security, and improving trust through its decentralized and transparent ledger system. However, challenges such as scalability, regulatory concerns, and high energy consumption hinder its widespread adoption. This study analyzes the impact of blockchain on digital transactions through a mixed-method approach, including surveys and interviews with 200 participants and 20 industry experts. The findings reveal that 60% of participants from high-volume transaction sectors cite scalability as a major barrier, while 45% mention regulatory uncertainty as a deterrent. Despite these challenges, the study highlights opportunities for blockchain in enhancing efficiency, security, and transparency across industries. Collaborative efforts among stakeholders, continuous research and development, and education initiatives are crucial for overcoming these challenges and promoting blockchain adoption. The research emphasizes the need for clear guidelines, robust standards, and increased awareness to ensure the successful implementation of blockchain technology. By addressing these issues, organizations can leverage blockchain to achieve secure, transparent, and efficient digital transactions, ensuring competitiveness in the evolving digital landscape.Blockchain technology is transforming digital transactions by eliminating intermediaries, enhancing security, and improving trust through its decentralized and transparent ledger system.
