Ethereum Constantinople Upgrade：

🌟Ethereum 2.0, which introduces a new consensus mechanism called Proof of Stake (PoS). This consensus mechanism replaces the Proof of Work (PoW) used in earlier versions and makes Ethereum_s network energy consumption lower than that of traditional PoW networks.

In addition to the new consensus mechanism, Ethereum 2.0 also introduces many other improvements, such as sharding technology, contract optimization, network protocol upgrades, etc., to further improve performance and security. The entire upgrade process is divided into multiple phases, with the current stage being the development and testing of the second phase, named "Mason". In the second half of this year, attention can be focused on coins in the L2 field, and currently Ethereum series is viewed as the leader in this area.
