We wish you a happy meal with the Ethereum London Hard Fork. It is an update of the Ethereum network and an important intermediate building block on the way to "Ethereum 2.0", where the basic mechanism of the Ethereum blockchain is to be changed from the cost- and energy-intensive "Proof of Work" mechanism to the so-called "Proof of Stake" mechanism, which is to work much more cost-effectively, scalably and quickly.
