Understanding Layer-2 Solutions on Ethereum

Ethereum, the second-largest cryptocurrency by market capitalisation, has been a cornerstone of the blockchain ecosystem since its inception. However, as the network has grown, so too have its limitations, particularly in terms of scalability and transaction costs. This is where Layer-2 solutions come into play. These solutions aim to enhance the Ethereum network by addressing its inherent limitations without compromising on security or decentralisation.

What Are Layer-2 Solutions?

Layer-2 solutions are protocols built on top of the Ethereum blockchain (Layer-1) to improve its performance. They aim to increase transaction throughput and reduce fees, making the network more efficient and user-friendly. These solutions operate by offloading some of the computational work from the main Ethereum chain, thereby alleviating congestion and lowering costs.

Types of Layer-2 Solutions

There are several types of Layer-2 solutions, each with its own unique approach to solving Ethereum’s scalability issues. The most prominent types include:

• State Channels: These allow participants to conduct multiple transactions off-chain, with only the final state being recorded on the Ethereum blockchain.
• Plasma: A framework for creating scalable applications by offloading transactions to child chains.
• Rollups: These bundle multiple transactions into a single transaction, which is then recorded on the Ethereum blockchain.
• Sidechains: Independent blockchains that run parallel to the Ethereum mainnet, allowing for faster and cheaper transactions.
