Having lower block rewards may not seem to directly affect the validation process of a blockchain network, but it can have a positive impact on the network in the long run. By lowering the block rewards, more developers may be attracted to the network. This is because the lower rewards will make it easier for developers to join the network without having to invest large amounts of money to compete with miners for the block rewards. Additionally, the lower rewards will also make it easier for the network to attract more developers, which can lead to more innovation and development of the network. Ultimately, this can lead to a more secure and efficient network, which will benefit everyone involved.
