Modular Blockchains & Data Availability Layers: How Celestia/EigenLayer Reshape L2/L3 Design

Blockchain networks have seen rapid adoption across industries. In 2025, the business value generated by blockchain is expected to reach $176 billion. Projections estimate this will climb to over $3 trillion by 2030.

Yet, scaling remains a major challenge. Bitcoin and Ethereum process only 7 and 30 transactions per second. In comparison, Visa handles nearly 24,000 transactions per second. This gap underscores the importance of scalability.

To solve this, the industry is moving away from monolithic blockchains. Modular blockchains have gained traction as a promising alternative. These architectures divide consensus, execution, and data availability into separate layers. In doing so, they promise higher throughput, lower costs, and custom blockchain solutions.

Pioneers like Celestia and EigenLayer are leading this evolution. Their advances in data availability and restaking are redefining Layer 2 and Layer 3 development. This trend opens the door to new blockchain development services and blockchain as a service models.

Mindfire Solutions stands ready to help enterprises leverage these innovations. As a trusted provider of custom blockchain development services, Mindfire Solutions delivers scalable, secure, and future-ready blockchain solutions for the evolving digital marketplace. 

With that being said, let’s get started.

Understanding Modular Blockchains

Modular blockchains represent a significant breakthrough in the structure of blockchain networks. Instead of having one network handle everything, modular blockchains divide core tasks. This includes dividing tasks such as transaction execution, consensus, and data availability into distinct layers.

How it Differs from Monolithic Blockchains 

This approach is different from monolithic blockchains. In a monolithic system, every node carries out all responsibilities. This structure limits scalability and flexibility as the network grows.

By specializing in each layer, modular blockchains overcome these bottlenecks. Developers can optimize each layer for its specific purpose. For example, one layer might focus on maximizing transaction speed, another on reaching consensus efficiently, and yet another on scalable data storage.

This architecture brings improved performance, security, and adaptability. Businesses benefit from faster transaction processing, lower fees, and more options for integration. Scalable systems like these are fueling demand for advanced blockchain development services.

Monolithic blockchains struggle to upgrade, but modular solutions make it easier to add or improve components. This flexibility means rapid innovation and the ability to deploy custom blockchain development services tailored to unique business needs.

Data Availability Layers: The Foundation

Data availability is central to every blockchain network. It guarantees that transaction data is published and accessible to all network participants. Without reliable access to this data, validators cannot confirm transaction legitimacy, and the chain's security can be compromised.

Why Data Availability Layers Matter

Traditional blockchains handled data availability, transaction execution, and consensus within a single layer. This monolithic approach causes bottlenecks and high costs, particularly as the number of transactions grows.

With modular blockchains, a dedicated data availability layer ensures all raw transaction data is reliably stored and easily accessible. These layers allow execution and consensus to focus on their specific functions, driving efficiency.

How This Separation Helps

This separation brings real benefits to custom blockchain development. Execution layers, such as rollups, post their data to the data availability layer, allowing nodes to verify transactions without downloading the entire chain. The result: faster settlement, lower costs, and scalable blockchain solutions.

Platforms like Celestia specialize in this model. By offloading data storage and availability from Layer 1, new projects and businesses unlock higher throughput and robust, cost-effective blockchain as a service offerings.

Celestia and EigenLayer: Reshaping the Landscape

Celestia

Celestia pioneers the concept of a dedicated data availability layer for modular blockchains. Instead of handling execution, Celestia provides scalable, secure data availability for other blockchains and rollups.

Celestia’s breakthrough is data availability sampling (DAS). DAS lets lightweight nodes verify data without downloading entire blocks. As more nodes join, blockspace and network throughput increase rapidly while costs drop. According to recent analyses, Celestia can lower data availability costs by up to 95% compared to traditional approaches.

EigenLayer

EigenLayer advances the landscape with restaking. It enables projects to reuse staked assets, strengthening network security for Layer 2 and Layer 3 systems. By pooling security and decentralization, EigenLayer helps new chains or rollups access robust protection without starting from scratch.

The synergy between Celestia and EigenLayer drives major changes for blockchain development services. With lower barriers to entry, businesses are deploying custom blockchain development services faster and more securely than before.

Together, these platforms usher in a new era of blockchain as a service. Organizations can streamline L2/L3 development, achieve horizontal scaling, and manage costs while unlocking new revenue models previously out of reach with legacy, monolithic blockchains.

Case Study: Digital Vault System

A Canadian financial services client approached Mindfire Solutions seeking a secure and user-friendly solution for digital asset protection. The challenge was to construct a robust system to safeguard digital identities, manage complex asset portfolios, and honor personal digital wishes in unforeseen events.

The Groundwork

Mindfire Solutions developed a Digital Vault System based on a modular blockchain architecture. The backend leveraged Rust and Node.js, while React.js powered the frontend. For secure data flow and event handling, the team used Kafka and Ceph for distributed storage. Infrastructure tools included Docker, Kubernetes, and AWS, ensuring solutions were scalable and highly available.

The Result

This Digital Vault System exemplifies the power of custom blockchain development services. By architecting the solution using modular principles, Mindfire Solutions enabled seamless scalability and fast adaptation to changing requirements. Dedicated layers managed data storage, transaction flows, and user permissions. These decisions enhanced both cost-efficiency and security.

Mindfire Solutions’ approach delivered not only a secure digital vault for end users but also a future-ready product for the client’s evolving needs. The project underlines Mindfire’s capability to deliver blockchain as a service solutions at enterprise scale: solutions that are robust, modular, and tailored for regulated industries.
