A Systematic Review on Blockchain Scalability

Abstract

Blockchain is an exciting new technology that has garnered attention across multiple industries. This new technology offers several advantages, including decentralization, transparency, and immutability. However, several issues limit the effectiveness of this technology, such as scalability, interoperability, and privacy. A systematic review of blockchain scalability research was conducted using three primary databases: ACM, Science Direct, and IEEE. The review examined the state of the art in blockchain scalability, identifying the most important research trends and challenges. The solutions that have been established can be categorized into two main groups: those that pertain to block storage and those that pertain to the underlying blockchain mechanism. Numerous solutions were suggested for each main group. The most common proposed solutions for improving the scalability of blockchain networks in the literature are improving the consensus algorithm and using sharding. Most of the solutions were proof of concept and need more investigation in the future.

Discovering the Global Landscape of Agri-Food and Blockchain: A Bibliometric Review

“…The transparency alleviates concerns about food safety and authenticity [24]. Several studies have been conducted to address blockchain challenges and limitations such as scalability, data privacy, data accuracy, security, lack of regulations and adoption [25], [26], [27], [28], [29], [30]. However, additional research is required to explore the potential of blockchain technology in agri-food supply chains and to develop effective frameworks and models for its implementation.…”
