William Shatner, the famous Canadian artist who played Navy James T. Kirk in the legendary Star Trek saga, expressed his support for Ethereum and congratulated blockchain founder Vitalik Buterin for participating in the event. In particular, in his presentation, Shatner emphasized the environmental benefits of ditching proof-of-work consensus for proof-of-stake. As many studies have pointed out, especially analysts at the World Economic Forum, the energy consumption of Ethereum mining should be reduced by 99.5% because of the update. In addition, in the eyes of institutional investors, PoW with restrictions on cryptocurrency transactions should theoretically improve the status of ETH. Even so, the new problems of Ethereum, although the transition has enhanced very positive consequences, the Vitalik project has also encountered new problems. For example, in the first few days after September 15th, it was known that more than 40% of the PoS nodes in the Ethereum network were controlled by only 2 addresses, which caused many people to question the decentralization of the current blockchain. Another complication comes from your expectations, given the current sentiment in the digital currency space. This is about SEC Chairman Gary Gensler stating that ETH currently running on PoS can be considered a security. The official is right that PoS Ethereum is not mentioned in vain in consensus reasoning. Generating income by staking digital currency meets the Howey test to determine whether an instrument is a security, he said. ##Ethereum#Ethereum News
