Thereby, Proof of Stake improves blockchain scalability since the validation process is more efficient and gets rid of the power-consuming mining involved in Proof of Work, which contributes to slow transaction throughput in PoW systems. By a consensus mechanism, Proof of Stake reaches its efficiency by choosing validators in relation to the amount of cryptocurrency that has been staked, allowing for faster block creation and confirmation.
Scalability: PoS contributes much to scalability in that with its use, many validators can be supported on a network without noticeable performance degradation. This is because, unlike in the PoW mechanism where the resources of competing miners for block rewards in such a way lead to sluggish processing, PoS chooses validators randomly and thus limits unnecessary computational work. Streamlined processes mean faster transaction finality and higher throughput.
Another very important scaling improvement for PoS systems has been the concept of sharding, a technique that has something to do with splitting the blockchain into small pieces of shards, with each Shard able to process a set of transactions all simultaneously. Sharding is easier to realize under PoS because the distribution of validators across shards is much easier than miners under PoW. This kind of parallel processing of transactions significantly enhances the number of transactions per second that a PoS blockchain can handle.
Overall, PoS is more scalable than PoW because it allows faster transaction processing, greater validators, and techniques such as sharding that help further its throughput and efficiency.
