  The consensus algorithm used in blockchain networks has a direct impact on their scalability. Different consensus algorithms have different requirements in terms of computational power, network bandwidth, and storage capacity. For example, the proof-of-work (PoW) consensus algorithm used in Bitcoin requires miners to solve complex mathematical puzzles, which requires a significant amount of computational power. This limits the scalability of the network as the number of transactions increases. On the other hand, the proof-of-stake (PoS) consensus algorithm used in Ethereum 2.0 allows validators to create new blocks based on the amount of cryptocurrency they hold. This approach reduces the need for computational power and can potentially increase the scalability of the network. However, it also introduces other challenges such as the potential for centralization. Overall, the choice of consensus algorithm plays a crucial role in determining the scalability of blockchain networks.
