The Future of Ethereum

Ethereum’s transition to the proof-of-stake protocol, which enables users to validate transactions and mint new ETH based on their ether holdings, is part of a significant upgrade to the Ethereum platform. Previously called Eth2, this upgrade is now referred to only as Ethereum. However, Ethereum now has two layers. The first layer is the execution layer, where transactions and validations occur. The second layer is the consensus layer, where attestations and the consensus chain is maintained.

The upgrade added capacity to the Ethereum network to support its growth, which will eventually help to address chronic network congestion problems that have driven up gas fees.

To address scalability, Ethereum is continuing development of "sharding." Sharding will divide the Ethereum database amongst its network. This idea is similar to cloud computing, where many computers handle the workload to reduce computational time. These smaller database sections will be called shards, and shards will be worked on by those who have staked ETH. Shards will allow more validators to work at the same time, reducing the amount of time needed to reach consensus through a process called sharding consensus.19
