When working with Modular Blockchain, a blockchain architecture that splits consensus, data availability and execution into separate layers. Also known as layered blockchain, it lets each layer specialize and scale on its own.
In a modular setup, a Rollup, a scaling solution that bundles many transactions and posts a summary to a base chain sits on top of a Data Availability Layer, the part of the system that stores transaction data where everyone can read it quickly. Below that, the Execution Layer, the component that runs smart‑contract code and updates state handles the actual computation. Modular blockchain therefore encompasses rollups, requires a robust data availability layer, and relies on an execution layer to deliver final results. This split‑up design reduces bottlenecks because consensus can stay lightweight while execution and data storage scale independently.
Because the layers are separate, developers can pick the best tool for each job. Want ultra‑fast finality? Use an optimistic rollup on a cheap data availability network. Need privacy or zero‑knowledge proofs? Deploy a zk‑rollup that still feeds data to the same consensus layer. Traders notice lower fees and higher throughput, especially on busy networks like Ethereum, where modular solutions keep gas costs from exploding. The architecture also opens doors for cross‑chain bridges: a rollup on one chain can read data from another chain’s availability layer, making assets move smoothly without relying on a single monolithic blockchain.
Below you’ll find a curated list of guides, reviews and deep dives that show modular blockchain concepts in action. From wrapped tokens that live on rollups to DeFi platforms built on execution layers, each article gives practical steps, risk warnings and real‑world examples you can use right now.
