Modular Blockchain
Modular blockchain is a design paradigm that separates the core functions of a blockchain—such as execution, consensus, data availability, and settlement—into distinct, specialized layers or modules. This contrasts with monolithic blockchains, where all functions are tightly integrated into a single layer. The approach aims to improve scalability, flexibility, and efficiency by allowing independent optimization and innovation of each component.
Developers should learn about modular blockchains when building decentralized applications (dApps) that require high throughput, low latency, or custom functionality, as they enable horizontal scaling and reduce bottlenecks. It's particularly useful in scenarios like gaming, DeFi, or enterprise solutions where performance and adaptability are critical, as seen in projects like Celestia or Ethereum's rollup-centric roadmap.
