Compare to other mentioned consensus algorithms, PoA sustains fast transactions. The main objective of PoA was that barely validators have the fundamental right to commend the contracts along with new-fangled blocks. A node becomes a validator only when the node receives a high reputation score. Compared to other PoS and Pow, PoA is more vigorous because validators authenticate every transaction or contract with high integrity. If not, nodes are attached with negative status. More importantly, a solitary validator cannot grant any two successive blocks, preventing confidence from being central.
