How to scale Ethereum horizontally?

Ethereum is hard to scale because of its fixed gas limit per block, which restricts the number of transactions that can be processed.

This leads to network congestion, slower transaction speeds, and higher gas fees, negatively impacting the user experience and hindering widespread adoption.

There are 3 ways to horizontally scale Ethereum

☝️Solution 1: layer 2s and rollups

These include optimizing transaction processing speed and introducing layer 2 solutions, which operate on top of the Ethereum blockchain and share its security model.

Rollup technologies like Validiums and Plasmas are also being explored. They bundle multiple transactions into a single one on the main chain, significantly improving scalability.

🧮Solution 2: pre-compliers

A new development in this area is the introduction of pre-compilers such as

L1 sandbox call
L1 delegate call
L1 call

These pre-compilers enable L2 nodes to interact more efficiently with Ethereum's data layer.

This development allows for faster and more efficient processing of transactions and data, opening new pathways for scaling and enhancing the Ethereum ecosystem.

⚡️Solution 3: Booster rollups

These rollups operate by executing transactions on L2 as if they were on Ethereum's main chain.

This involves mirroring L1 contracts on L2, which simplifies DApp development and reduces the fragmentation across various L2 solutions.

This approach not only enhances scalability but also maintains the security and decentralization of the Ethereum network.
