This essentially means that those who receive Ethereum’s Ether tokens as a reward for maintaining the network will be removed from the process in order to streamline transactions. Instead, Ethereum users can deposit their tokens to keep the network secure and earn rewards instead.

“With the proof-of-stake, you can achieve a multiple, significantly higher multiple, in transactions per second, which improves utilization and the possibilities for creating Ethereum,” Cuban told Shin. Recalling the latest cryptocurrency craze for NFTs (non-fungible tokens) as “just proof of concepts” of what smart contracts can do.

“I think in a couple of years Ethereum and maybe two or three other blockchains will have their place and those will be the winners,” the Cuban said, adding that he won’t be selling his Bitcoin but that he will be “a lot more owns “” Ethereum as Bitcoin.
