Layer 3 (L3) blockchain solutions are gaining increasing attention for their potential to address scalability and interoperability challenges faced by existing Layer 1 (L1) and Layer 2 (L2) networks. Here are some of the top Layer 3 blockchains to watch out for in 2024:

1. Celestia

Celestia is a modular blockchain network designed to facilitate the deployment and execution of decentralized applications (dApps) at scale. It ensures the security of the blockchain by using a Proof of Stake (PoS) consensus mechanism and enabling the creation of modular execution environments called Celestia Clusters.

Celestia is backed by reputable investors like Polychain Capital and Andreessen Horowitz (a16z).

2. Cosmos Hub

While technically a Layer 1 blockchain, the Cosmos Hub serves as the central hub for the Cosmos ecosystem, facilitating interoperability between various Layer 1 and Layer 2 blockchains through its Inter-Blockchain Communication (IBC) protocol. The Cosmos Hub is expected to play a crucial role in enabling cross-chain communication and interoperability within the Layer 3 ecosystem.

3. Polygon Avail

Polygon Avail is a Layer 3 blockchain solution built on top of the Ethereum and Polygon networks. It aims to provide scalable and secure execution environments for decentralized applications, leveraging Polygon's existing infrastructure and Ethereum's robust security model. Polygon Avail is designed to offer high throughput, low latency, and cost-effective transactions.

4. Starknet

Starknet is a decentralized Layer 3 blockchain built on top of Ethereum, utilizing ZK-Rollup technology for scalability and privacy. It enables developers to deploy and execute smart contracts with enhanced performance and lower transaction costs compared to Ethereum's main chain. Starknet has gained significant traction and is supported by projects like Immutable X and Argent.

5. Metis

Metis is a Layer 3 blockchain solution designed to provide scalability, security, and interoperability for decentralized applications. It leverages Optimistic Rollup technology to achieve high throughput and low transaction costs while inheriting Ethereum's security guarantees. Metis aims to facilitate the development and deployment of Web3 applications across various domains.

The blockchain space is gaining attention from the tech community, developers are actively building, and users need speed and scalability - that's what layer 3 solutions aim to provide.
