The new Ethereum chain started less than a month ago, and since then, it became the fourth biggest network with PoS consensus. It’s come from the USD-value, locked for the mining. The first three spots belong to Polkadot, Cardano, and Tezos, but ETH2.0 growing really fast, the pedestal isn’t far.
Proof of stake mining consumes way less energy than the PoW, Bitcoin’s method. The community looking for better scaling of Ethereum, with the new chain. A bigger stake-amount means bigger network security, but it may decrease the level of adoption, usability, and velocity of the cryptocurrency. What are locked, that is locked, it not move, not transact, don’t do anything, only for more reward. But this may become a senseless repeated loop for network members. The “stake for the more stake” sounds cool, but the clear final goal is missing.
