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 ...
