It’s an exciting time in the blockchain world! Perhaps one of the most exciting concepts on the horizon are these new modular blockchains. Modular blockchains change the game in how we process blockchain work. Rather than doing everything from consensus to data availability to execution in the same place, they grouped these activities into distinct, highly specialized layers. This in turn enables scalability, flexibility, and efficiency to be magnified. GreedyChain.com takes you behind the scenes to help you discover the 5 modular blockchains to watch. These innovations are poised to be game changers well before 2025. No nonsense, just knowledge for smart people who want to get smarter.

What are Modular Blockchains?

Think of a monolithic blockchain as a Swiss Army knife. It has a deep toolbox, but it’s not necessarily the best tool for the job. A modular blockchain works more like a toolbox of specialized instruments. That’s because each tool is designed to advance a very particular purpose. Modular blockchains improve performance by dividing up important functions. They address consensus to agree on the blockchain’s state, data availability to make transactions accessible, and execution to process transactions fast and easily.

Why Modular?

In doing so, modular blockchains provide a diversity of key advantages over their monolithic counterparts. Scalability is a major one. Modular chains distribute the workload across several layers allowing them to support more transactions and users. They do all this while maintaining a high level of performance and security. Flexibility is another benefit. By using a modular architecture, developers can pick and choose the specific modules that best suit their needs, creating highly customized blockchain solutions. Modular designs increase system-wide efficiency. They free up specialized components to focus on what they do best, allowing the system as a whole to achieve faster transaction times and reduced operational costs.

How Does Modularity Work?

The core idea is simple: separate and conquer. In a modular blockchain, the base layer handles consensus and data availability. In parallel, different execution layers process transactions, usually as their own transaction pools. This separation of concerns lets every layer concentrate on doing the one thing it’s meant to do best, resulting in better performance and scalability.

Top 5 Modular Blockchains to Watch in 2025

Here’s GreedyChain.com's breakdown of the top 5 modular blockchains that are expected to make waves in 2025:

1. Celestia: The Data Availability Powerhouse

Celestia is at the forefront of developing and commercializing this idea of data availability sampling (DAS). Its priority is on just guaranteeing availability of transaction data and deferring execution to other layers. Celestia’s specialization is what enables it to achieve massive scalability, and to serve as a foundational layer for other modular blockchains.

Celestia’s modular architecture removes the complexity by separating the work of consensus, data availability, and transaction execution into independent layers. Its incentivized airdrop campaigns have resulted in explosive price appreciation and user onboarding, showing incredible community commitment. By zeroing in on data availability, Celestia lets users rapidly deploy their own sovereign and decentralized modular or rollup blockchains. This method cultivates new ideas and avoids the need to create a fresh consensus network from scratch.

2. Manta Network: Privacy-Focused Modular Chain

Manta Network is building a modular, application-specific blockchain that incorporates Celestia for data availability. It makes use of zkEVMs, or zero-knowledge Ethereum Virtual Machines, to execute. This powerful combination enables Manta to provide privacy-preserving smart contracts and decentralized applications (dApps).

Manta Network’s architecture unlocks Celestia for data availability with a zkEVM core execution engine, forming a modular system purpose-built for privacy. Through the unique use of zkEVM, Manta Network achieves extreme scalability and security, while offering a degree of privacy that goes beyond the public layer. The network’s modular architecture enables developers to create and deploy privacy-centric applications at scale with enhanced efficiency. This feature alone makes it a phenomenal option for enterprise-level projects that require discretion and heightened security.

3. Arbitrum: The Rollup Leader

Arbitrum Rollup-based Layer-2 scaling solution for Ethereum. It pools together thousands of transactions and sorts them within a batch, or “rollup,” which is eventually submitted back to the Ethereum mainnet. This greatly minimizes transaction costs and maximizes throughput.

Using rollup technology to increase both scalability and security, Arbitrum has quickly positioned itself as one of the top Layer-2 solutions. As it’s based on EVM, the Ethereum Virtual Machine, deploying existing smart contracts is easy for developers. This user-friendly experience fosters community participation and increases adoption. Enhanced Scalability & Throughput The Arbitrum Virtual Machine (AVM) is designed to maximize transaction processing efficiency, playing a pivotal role in the network’s overall performance and developer-friendly environment.

4. Optimism: Ethereum-Aligned Scaling

Optimism is yet another Layer-2 scaling solution that uses this same, rollup-centric architecture. Its stated purpose is to underpin a secure and interoperable ecosystem that’s easy for developers to build in, to enable decentralized applications on Ethereum and beyond.

Short for “scalar, or multiple,” rollups Optimism’s rollup-centric architecture increases scalability by processing transactions off-chain and then posting those transactions to Ethereum. Execution mainly happens over on Optimism, with final results transferred back over to Ethereum, alleviating congestion during the height of Ethereum’s mainnet. This execution environment enables a superior developer experience through a high level of Ethereum compatibility, with developers able to easily migrate and deploy their applications.

5. Berachain: Proof-of-Liquidity Innovation

Among these Berachain certainly has its differentiators, including a unique Proof-of-Liquidity (PoL) consensus mechanism. Rather than relying on a typical Proof-of-Stake model, Berachain gives incentives to users who chunk liquidity into the network. This encourages network participation and plays a meaningful role in keeping the blockchain secure and stable.

Unlike conventional Proof-of-Stake mechanisms, Berachain’s Proof-of-Liquidity (PoL) system rewards liquidity providers directly, making it one of the core characteristics that sets Berachain apart. Combined with its triple-token economy—which includes BERA (gas), BGT (governance), and HONEY (stablecoin)—this fosters an ecosystem built on equilibrium. This innovative approach fosters a more engaged and stable community, driving adoption and enhancing the overall functionality of the Berachain network. Coupled with a developer-friendly platform that makes deploying new smart contracts extremely simple, it further incentivizes community participation.

Diving Deeper: Key Aspects of Modular Blockchains

Let’s get into the details of what makes these modular blockchains tick:

Technology

Under the hood, each of these blockchains uses different technologies to get there. Celestia is a modular blockchain that specializes in data availability sampling, and MantaNetwork uses Celestia as a foundation combined with zkEVMs. Arbitrum and Optimism both use rollup technology, and Berachain has introduced a completely new Proof-of-Liquidity consensus mechanism.

Tokenomics

Tokenomics is one of the most important aspects underlying the success of any blockchain, layer 1 or otherwise. Berachain, for instance, employs a multi-token model with $BERA as the transactional token and $BGT as the governance asset. This intentional separation of joint utility and decision-making functions fosters a more equitable, flexible, and sustainable ecosystem. You have not received detailed tokenomics information for other chains in the above provided context. For investors, knowing the tokenomics of each project is key.

Community Engagement

In closing, investment in community engagement is critical to the development and success of any blockchain initiative. Celestia's incentivized airdrop campaigns and ME Network's testnet incentives are examples of how to drive participation and onboard new users. Developer-friendly platforms like Berachain and Arbitrum make it easy for developers to build and deploy dApps. These platforms improve community engagement by bringing new levels of collaboration and innovation to the process.
