Answer: While Proof of Stake (PoS) may have helped in some ways, such as providing a more secure network and reducing the cost of transactions, it is not likely to have had a major impact on reducing transaction fees. This is because, even though PoS may reduce the need for miners, it does not necessarily reduce the amount of data that needs to be processed in order to complete a transaction. Therefore, the only way to significantly reduce transaction fees is to implement sharding, which will allow the network to process more transactions in parallel and reduce the amount of data that needs to be processed. This should lead to significantly lower transaction fees, as more transactions can be processed in the same amount of time.
