Ethereum layer 2 scalability solutions

What Does the Top 10 Ethereum Layer-2 Scaling Solutions Contribute to the Web3 Realm in 2024?

In the ever-evolving blockchain landscape, many layer-2 blockchain solutions are gradually showcasing themselves in the market. These solutions mainly resolve Ethereum’s scalability challenges and embody a multifaceted approach to addressing network scalability and transaction diversity challenges.

This blog delves into the basics of layer-2 blockchain networks with a list of top Ethereum layer 2 scalability solutions in 2024.

Understanding Layer-2

Layer-2 technology encompasses scaling solutions aimed at alleviating congestion by utilizing secondary blockchains. These secondary blockchains extend the main network’s capabilities while inheriting the primary blockchain’s security assurances.

Theoretically, layer-2 solutions have unlimited capacity, enabling substantial reductions in transaction fees and enhancements in processing speeds, thereby augmenting the overall efficiency of layer-1 networks.

How Does Layer-2 Function?

Layer-2 technology utilizes “rollups” to aggregate and process transactions within the environment before transmitting the updated data to the mainnet. This approach alleviates the Ethereum network from individually processing numerous DeFi transactions, as the computation is delegated to layer 2.

What are the Different Types of Layer-2 Solutions?

While various Ethereum Layer 2 scaling solutions exist, rollups are the most prevalent choice currently employed. Rollups streamline multiple transactions into a unified entry recorded on the primary Ethereum blockchain. These rollups come in two main types, including:

Optimistic Rollups

Optimistic rollups operate on the assumption of transaction validity but allow for challenges if doubts arise. A fault-proof mechanism is employed for scrutiny in cases of suspected invalid transactions.

Zero-knowledge Rollups

Zero-knowledge rollups utilize off-chain processing to bundle and compute numerous transactions, generating cryptographic proof. Subsequently, this compressed data is transmitted to the Ethereum mainnet as evidence of their legitimacy.

While Optimistic Rollups leverage economic incentives and game theory to validate transactions, Zero-Knowledge (zk) Rollups utilize cryptographic proofs to ensure security and privacy.

Top 10 Layer-2 Ethereum Scaling Solutions You Should Look Out in 2024

Among the diverse blockchain networks, there are some highly capable Ethereum-focused layer-2 solutions for scalability, including:


  • Arbitrum improves transaction speed and efficiency by shifting processing to a secondary blockchain while staying linked to the Ethereum mainnet.
  • It also simplifies the deployment of Ethereum-compatible smart contracts, streamlining the migration of dApps and DeFi protocols and alleviating the Ethereum network’s burden.
