Diagram illustrating a modular blockchain with separate consensus, execution, and data availability layers

The rise of modular blockchain designs has transformed the scalability and architecture of decentralized networks. Unlike monolithic chains, modular blockchains separate consensus, execution, and data availability into specialized layers. Among these, the Data Availability Layer (DAL) plays a critical role in ensuring that blocks can be securely verified and reconstructed by all participants without overwhelming … Read more

Zero-Knowledge Rollups vs Optimistic Rollups: Performance Benchmarks

March 29, 2026February 25, 2026 by Panji Yudian

Technical comparison of zero-knowledge rollup and optimistic rollup blockchain scaling architecture

Layer 2 rollups have become the dominant scaling strategy for Ethereum-class blockchains. Among them, Zero-Knowledge (ZK) rollups and Optimistic rollups represent two fundamentally different trust and performance models. Both dramatically reduce Layer 1 congestion—but their real-world behavior diverges in latency, cost structure, security assumptions, and developer ergonomics. Understanding the benchmark differences is essential for choosing … Read more
