Cronos has successfully completed a major performance upgrade to its EVM mainnet, achieving sub-second block times and solidifying its position among the top 10 fastest blockchains globally. This milestone marks a transformative leap in network efficiency, enabling real-time decentralized applications across DeFi, AI, and digital payments.
Effective July 3, 2025, the Cronos EVM mainnet now produces blocks in under one second—down from a previous average of 5.6 seconds. This 10x improvement in block time dramatically enhances transaction finality, throughput, and user experience, setting a new standard for high-performance Ethereum Virtual Machine (EVM)-compatible chains.
With instant finality and ultra-low latency, Cronos is now optimized for next-generation use cases that demand speed and reliability. Developers can build high-frequency trading platforms, real-time gaming economies, and AI-driven smart contracts with confidence in the network’s responsiveness.

Powering Speed Through Parallel Execution
The breakthrough in block time is made possible by BlockSTM, a parallel execution engine introduced during the recent Pallene upgrade. Unlike traditional sequential transaction processing, BlockSTM allows multiple transactions to be executed simultaneously within a single block, significantly boosting computational efficiency.
This technology, originally developed by Mysten Labs and adapted for Cosmos-based chains like Cronos, enables the network to maximize hardware utilization and reduce bottlenecks. When combined with increased block production frequency, the result is a seamless, high-throughput environment where transactions are confirmed almost instantly.
Developers benefit from reduced wait times, predictable gas costs, and smoother integration with front-end interfaces—critical advantages for applications requiring real-time feedback loops.
Key Benefits of the Upgrade
The combined effect of BlockSTM and accelerated block production delivers tangible improvements across the ecosystem:
- Higher transaction throughput (TPS): The network can process more transactions per second without congestion.
- Near-instant finality: Users experience immediate confirmation, essential for payment systems and interactive dApps.
- Improved developer experience: Faster feedback loops streamline testing and deployment.
- Lower latency for on-chain interactions: Ideal for AI agents, automated trading bots, and live gaming environments.
These enhancements align with Cronos’ broader vision of building a scalable, affordable, and developer-friendly blockchain infrastructure ready for mass adoption.
Strategic Focus on Performance and Accessibility
This speed upgrade follows a series of strategic optimizations aimed at improving accessibility and usability. In June 2025, Cronos implemented a 10x reduction in base gas fees, making it significantly cheaper to deploy and interact with smart contracts. This dual focus on low cost and high speed positions Cronos as an attractive platform for startups and enterprises alike.
Moreover, the network is actively preparing for the rise of autonomous AI agents—software entities that can execute on-chain actions independently. With sub-second finality and efficient execution, Cronos provides the ideal environment for these agents to operate reliably at scale.
Real-World Adoption and Financial Integration
Cronos has already demonstrated strong traction beyond technical benchmarks. In collaboration with Crypto.com, it became the first blockchain to enable direct crypto funding of prepaid cards, bridging the gap between digital assets and everyday spending.
A key feature supporting this integration is Auto-Harvest, which automatically converts DeFi rewards into fiat currency to top up user cards. This innovation simplifies the user journey, allowing individuals to earn yield on-chain while enjoying seamless off-chain utility.
Such use cases exemplify Cronos’ mission: to make self-custody in Web3 easy, safe, and practical for the next billion crypto users.
The Cronos Ecosystem: Three Chains, One Vision
Cronos operates a multi-chain architecture designed to serve diverse needs within the decentralized economy:
- Cronos EVM: An Ethereum-compatible chain built on the Cosmos SDK, ideal for DeFi and dApp development.
- Cronos POS: A Cosmos-based proof-of-stake chain optimized for payments and NFTs.
- Cronos zkEVM: A high-performance Layer 2 network secured by Ethereum, offering scalability without sacrificing security.
Together, these chains support over $6 billion in user assets and have processed more than 100 million transactions since launch. The ecosystem benefits from strong backing by Cronos Labs, a Web3 accelerator focused on nurturing innovation in DeFi, GameFi, and developer tooling.
