Is Ethereum 2.0 complete?

Ethereum 2.0, also known as Serenity, represents a major upgrade to the Ethereum network. It aims to improve scalability, security, and sustainability by transitioning from a Proof of Work (PoW) to a Proof of Stake (PoS) consensus mechanism and introducing sharding. The upgrade process has been divided into multiple phases, with the initial phases focusing on the launch of the Beacon Chain and the implementation of sharding. However, the full completion and rollout of Ethereum 2.0 are still ongoing, with various development teams working on different components of the upgrade.
