<ul data-eligibleForWebStory="true">IoTeX activated its v2.2 hard fork, achieving sub-three-second transaction finality on June 19.The upgrade brings a reduction in block time from 5 to 2.5 seconds, enhancing user experience.This development benefits latency-sensitive use cases like on-chain AI agents, DePIN networks, and DeFi.IoTeX aims for 2,000 transactions per second in future upgrades without compromising security.The upgrade is driven by enhancements to IoTeX’s Roll-DPoS consensus, including Optimistic Block Minting.Innovations ensure network operation under high load while maintaining decentralization.IoTeX introduced a timestamp-based staking contract (v3) for improved accuracy and user experience.Legacy v1 staking contracts are still supported with adjusted options.The v2.2 upgrade includes foundational updates for performance and reliability.IoTeX becomes the first decentralized Layer 1 to achieve sub-three-second finality without Layer 2 or centralized sequencers.The roadmap focuses on security-first scaling, with future upgrades exploring sub-second finality.Gas limits will remain conservative, and changes will be made cautiously after extensive testing.IoTeX Core v2.2 is live, aiming for instant finality and secure throughput for real-world applications.Users are encouraged to check the official GitHub release notes for technical details.Media Contact: press@iotex.io www.iotex.io
