This new release marks a significant leap toward onboarding institutional investors and corporations onto blockchain systems, bridging the gap between traditional finance and public blockchain ecosystems through advanced cryptographic technology.
What the Atlas Upgrade Brings
According to ZKsync’s official statement, the Atlas upgrade introduces a next-generation sequencer capable of processing between 25,000 and 30,000 transactions per second (TPS) , a major improvement in throughput for real-time blockchain applications such as financial transactions and gaming.
Atlas also integrates a new proof system called Airbender, which enables transaction finality in under one second. This advancement eliminates one of the biggest hurdles for large-scale institutional blockchain adoption: latency and network performance.
Despite these performance gains, Atlas retains full compatibility with Ethereum-based applications, meaning enterprises can seamlessly deploy custom, compliance-ready blockchain networks while still interacting with existing decentralized applications (dApps).
Rising Institutional Demand for Blockchain
The timing of the Atlas upgrade aligns with growing institutional demand for blockchain-based financial infrastructure, particularly as tokenized assets and blockchain settlement systems gain global traction in 2025. Financial institutions are increasingly looking for solutions capable of processing high transaction volumes at the speed required for real-world finance, such as cross-border payments and cryptocurrencies transfers.
ZKsync’s semi-public blockchain model directly addresses this need by enabling companies to build Ethereum-connected private or semi-open chains, balancing regulatory compliance with the transparency and liquidity benefits of public blockchains.
Modularity and Enterprise Flexibility
Atlas’s modular architecture allows institutions to tailor their blockchain deployments without compromising on security or transparency.
Use cases include tokenized real-world assets, settlement systems, identity management, and institutional financial infrastructure.
Every operation is secured through zero-knowledge cryptography, ensuring verifiable integrity while giving enterprises control over key parameters like transaction visibility and execution logic.
This upgrade follows ZKsync’s growing list of strategic partnerships with major financial players such as Deutsche Bank, and enhances cross-chain interoperability across networks built with ZK Stack, a critical step toward realizing the company’s long-term vision known as “The Elastic Network.”
