IOTA (MIOTA) Enables Starfish Consensus, Targets Scalability
IOTA (MIOTA) has officially deployed its Starfish consensus protocol on the Mainnet, introducing a groundbreaking approach to network reliability and scalability. The v1.21.1 release, which launched on April 28, 2026, upgrades the protocol to version 24 and integrates Starfish, a leaderless Byzantine Fault Tolerant (BFT) system designed to address bottlenecks in Directed Acyclic Graph (DAG)-based consensus mechanisms. At its core, Starfish aims to solve a critical issue in DAG structures: dissemination. Traditional consensus often focuses on validators reaching agreement, but Starfish emphasizes how information is shared efficiently within the network. Without proper synchronization, validators cannot certify data or maintain progress, especially under high load or partial network failures. Starfish addresses this through an innovative mix of “push” and “pull” strategies for data sharing, striking a balance between efficiency and latency. Why Starfish Matters Starfish represents a major step forward for IOTA‘s ambition to power real-world applications, such as global trade and enterprise systems. Unlike traditional blockchain solutions, which often face scalability challenges or high energy consumption, Starfish leverages IOTA’s DAG structure to enable parallel transaction processing and high throughput. One of the protocols key features is its separation of metadata from transaction payloads. Metadata, which contains essential consensus data like references and votes, is
