Because of the structure of representative governance, Bitcoin called the typical first generation is hard to upgrade. And PoW patterns could be influenced by Miners’ interest in mining profit, it harmed the concept of decentralization.
That comes from miners’ who provide computing power getting bigger. Ethereum rear up the problem of delaying speed from raise of dater process volume, and the problem of raising of the Gas fee the transfer commission.
Following first and second-generation main-net create a block using PoW pattern have the fundamental problem of computing power and overspending of electric source. So in Ethereum 2.0 try to transfer to the PoS pattern. But in November 2020 the problem is still unsettled.
PoS 3.0
