>"Ethereum development is reaching a new level of maturity. The gap between where Ethereum is currently located and its defined roadmap is rapidly closing. Now that we are at this stage, it is clear that Ethereum is developing a modular design architecture . The attributes that make the blockchain a “blockchain” are showing a trend of differentiation, so that each chain can realize its own optimal vision. In this article, we will explore the PoS (proof of equity consensus mechanism) , fragmentation (sharding) and how Rollups the modular design of the block chain, in order to achieve long-term vision Ethernet Square, and set up blocks for the future development of chain Set standards."
