What is it?
Modular blockchains separate the core functions of a blockchain (execution, consensus, data availability, settlement) into distinct layers or specialized chains. This design contrasts with monolithic chains like Ethereum that handle all functions on a single layer.
Why it’s trending:
✅ Boosts scalability by letting different layers optimize specific tasks
✅ Projects like Celestia (data availability), Fuel (execution), and Avail are gaining traction
✅ Supports rollups and Layer 2 solutions more efficiently
✅ Attracts developer interest for building next-gen dApps
Risks:
❌ Complexity in coordination between modular components
❌ New infrastructure = less-tested security assumptions
❌ May fragment liquidity and developer ecosystems
Conclusion:
Modular blockchains are gaining attention as a serious answer to the scalability trilemma. As Web3 applications demand better performance, this architecture could reshape the base layer of crypto.
