After mainframes, people computers, the internet, mobile communications, and social media, blockchain has been dubbed the sixth disruptive technology. For system decentralization, it is referred to as a distributed peer-to-peer (P2P) database enabler. There is a scalability issue that is a major roadblock to widespread Blockchain adoption. The goal of this study is to overcome the barriers that are preventing this technology from becoming as widely accepted as it was designed to be. This research provides the groundwork for an improved blockchain by identifying the right balance between block size and block interval, switching to a better consensus mechanism like PoS, and indicating sharding.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
