Kritika Sharma, Naveen Kumar, Rajesh Kumar Kaushal · 2023
With its decentralised, secure, and transparent solutions, blockchain technology has become a paradigm-shifting force in a variety of industries. This comprehensive review moves around the complex world of blockchain applications, thoroughly classifies each type, analyses current issues, and looks ahead to potential future applications. The study, which spans industries including finance, healthcare, supply chain, and more, highlights how blockchain has the power to completely transform data management, transparency, and trust. The public, private, consortium, hybrid blockchain types are all systematically categorised in the study and each is suited to a different set of needs. The assessment highlights how blockchain's architecture can transform sectors that previously relied on middlemen by emphasising decentralised consensus methods. Key considerations include issues with interoperability, scalability, data privacy, and regulatory compliance. Based upon current literature in the field, the study emphasises the urgent necessity for comprehensive research and innovative approaches in order to address these gaps and facilitate the appropriate implementation of blockchain technology. This analysis gives a complete summary of the uses, problems, and future trajectories of this omnipotent technology. It serves as a necessary guide for researchers, practitioners, and policymakers, as they navigate the growing influence of blockchain.
