Mark Cuban is ‘very bullish’ on the upcoming Ethereum ‘merge.’

$Ethereum(ETH.CC)$
After the merge, Ethereum’s crypto mining would become obsolete, which would substantially reduce Ethereum’s environmental impact. The supply of new Ether would also likely decline, because fewer coins are expected to be issued. Additionally, blockchain security against potential attack is supposed to improve. And institutional investment in the Ethereum network is expected to increase.
Two key updates post-merge, according to Cuban
To Cuban, the merge is important for two key reasons.
First, he mentioned the importance of Ethereum going to proof of stake. Ethereum currently relies on what’s known as proof of work, under which miners must complete complex puzzles to validate transactions. This process requires a huge amount of computer power and is often criticized due to its environmental impact. With the planned upgrade to proof of stake, users would be able to validate transactions according to how many coins they contribute, or stake. In return for staking more coins, users have a higher likelihood of being chosen to validate transactions on the network and earn a reward. Currently, Ethereum has both proof-of-work and proof-of-stake chains running in parallel. While both have validators, only the proof-of-work chain currently processes users’ transactions. Once the merge is complete, Ethereum's blockchain will shift fully to the proof-of-stake chain, called the Beacon Chain, making mining obsolete.As a result, it’s predicted that Ethereum’s energy consumption will be cut by 99%.
Second, Cuban said he’s interested in less Ether issuance after the merge, and how “that will possibly make it deflationary.”
