Security, privacy, and genuineness are fundamental requirements for secure data sharing in the digital age. Blockchain technology has a distributed and unchangeable nature that handles these worries by using encryption techniques like digital signatures and hashing. It removes middlemen and lowers the possibility of data breaches by automating access control and guaranteeing that data is shared in a secure environment. Moreover, blockchain does not allow third-party to do any authorized changes or modifications to the existing network. This helps to build trust among stakeholders. This study suggests how blockchain can be used in various industries along with the comparative analysis of traditional data sharing methods and existing data sharing solutions.
