Blockchain, or BC, is a cryptographic system that allows for the immutable storing of transaction records across various places. This is one of the key reasons why so many businesses are thinking about incorporating blockchain technology into their IT architecture. Even though BC-based systems are used in a range of business solutions, concerns about privacy, scalability, performance, and accessibility persist. Permissioned Blockchain (PBC) frameworks offer a safe way to store sensitive information. The primary goal of this research is to look into the scalability and possible growth of big private blockchain platforms. Every platform was assessed using a variety of roles and success indicators. Businesses may evaluate which private blockchain solution is best for them by conducting extensive research on the benefits and drawbacks of each platform.
