The upgrade represents a major technical leap for Ethereum, offering significant improvements in speed, cost, and integration between layers. ZKsync, a leading layer 2 scalability solution, revealed that Atlas can achieve over 15.000 transactions per second (TPS), with completion in about one second and virtually zero fees.

According to Alex Gluchowski, co-founder of ZKsync, these impressive results are “just a small part of the story.” The main change lies in how Atlas redefines communication between Ethereum and its layer 2 networks, enabling smoother and more efficient interoperability.

Before its launch, each Layer 2 network—such as Arbitrum, Base, and ZKsync Era—needed to maintain its own liquidity reserve, leading to capital fragmentation and operational delays. With Atlas, this structure is replaced by a unified model, where Ethereum becomes the liquidity core for all associated networks.

This innovation allows transactions between Layer 2 to be completed in about one second and transfers between Layers 1 and 2 to occur in record time, drastically reducing confirmation time and costs.

Furthermore, the new system favors the advancement of institutional investors and real-world asset (RWA) projects, which require efficiency and security in financial operations. Funds that previously took days to move can now be settled almost instantly on Ethereum.

Buterin highlighted that ZKsync's progress reinforces Ethereum's role as a global base for financial settlements: “ZKsync has been doing valuable and underrated work in the Ethereum ecosystem. I'm excited to see this coming from them!”, he stated.

Atlas symbolizes a crucial advancement for Ethereum, making it more scalable, faster, and better prepared to support the growth of DeFi applications and high-performance institutional transactions.
