description: Blockchain is considered one of the most disruptive technologies of our time and in the last 2 decades andhas drawn attention from research and industrial communities. Blockchain is basically a distributed ledger with immutable records, mostly utilized to perform the transactions across various nodes after achieving the mutual consensus between all the associated nodes. The consensus protocol is a core component of Blockchain technology, playing a vital role in Blockchain�s success, global emergence, and disruption capability.Many consensus protocols such as PoW, PoS, PoET, etc. have been proposed to make Blockchain more efficient to meet real-time application requirements. However, these protocols have their respective limitations of low throughput and high latency and sacrifice on scalability.These limitations have motivated this research team to introduce a novel review-based consensus protocol called Proof-of-Review, which is aimed to establish an efficient, reliable, and scalable Blockchain. The �review� in the proposed protocol is referring to the community trust on a node, which is entirely depending on the node�s previous behavior within the network which includes the previous transactions and interaction with other nodes. Those reviews eventually become the trust value gained by the node. The more positive the reviews the more trustworthyis the nodeto be considered in the network and vice versa. The most trustworthy node is selected to become the round leader and allows to publish a new block. The architecture of the proposed protocol is based on two parallel chains i.e. Transaction Chain and Review Chain. Both chains are linked to each other. The transaction chain stores the transaction whereas the review chain will store the reviews and be analyzed with an NLP algorithm to find the round leader for the next round. © 2021
