Today PoW and PoS blockchains have conflicting interests between miners/validators and network users. Users would benefit from faster and cheaper transactions, but in general, this will increase costs to miners and validators, reducing their profits. A version of this conflict came up during Bitcoin’s Blocksize War, where some argued to increase the amount of data in a mined Bitcoin block, theoretically making transactions faster and cheaper. The corresponding cost for miners would be higher with bigger blocks, but fees would be lower. Who won out?
Bitcoin Mining Is an Oligopoly, and Proof-of-Stake Isn’t Any Better
