Performance Analysis of Public and Private Blockchains and Future Research Directions

Blockchain is growing rapidly and becoming popular to handle business needs over the globe. Smart contracts are one of the unique features of blockchain 2.0 which are disrupting the industry and creating new value for businesses that are looking for opportunities to grow in an untrusted environment. There are many blockchain platforms evolved for serving different purposes, but each has its own limitations and advantages. Due to the lack of performance analysis tools and a complete study comparing public and private blockchain platforms, the researchers are focusing more on analyzing performance and comparing results. Considering these aspects, there is a necessity to conduct a performance study and comparison of public and private blockchain platforms. Here in this work, the performance and scalability issues of blockchain platforms are presented and provided in detail study, future scope. This work compares the existing blockchain platforms’ performance and discusses their pros and cons, in terms of performance and scalability.
