The Ethereum ecosystem has selected a long-term roadmap known as Ethereum 2.0, also known as the Ethereum upgrades. Three fundamental steps make up Ethereum 2.0, and two of them are already finished:
The transition of Ethereum from a proof-of-work to a proof-of-stake mechanism began with the Beacon Chain. Before PoS was introduced to the ecosystem, a test was conducted to make sure it was a viable future strategy for Ethereum's blockchain.
The Beacon Chain was launched after the Ethereum Merge. PoS and PoW coexisted before the Merge, but it served the aim of doing away with PoW.
The final improvement on the Ethereum roadmap is sharding. However, it is not projected to be completed until 2023. Ethereum Sharding places a greater emphasis on scalability and promoting network involvement than the earlier stages, which were more concerned with security and sustainability.
