zkSync implements changes following congestion

zkSync, a Layer 2 scalability solution based on ZK-rollup technology, has begun implementing fundamental improvements to address the challenges stemming from congestion on the Ethereum network. With the increasing adoption of dApps, tokens, and DeFi applications, optimizing performance and accessibility has become a critical priority.

Background: A rapidly saturating ecosystem

In early 2025, zkSync experienced activity spikes that caused delays, higher fees, and difficulties for developers deploying contracts. The community called for urgent adjustments to uphold the efficiency promised by ZK-rollup solutions.

Updates rolled out by zkSync

Starting in Q2 2025, zkSync introduced several technical and structural enhancements:

Protocol Version 28 (June 2025)

• Cryptographic function optimization: improvements to ecMul, ecAdd, and modexp for faster and more efficient calculations.
• Reduced computational costs for complex smart contracts.

zkSync Gateway

• Launch of an optional aggregation layer that facilitates interoperability across zkSync-based networks.
• Improved traffic management and transaction redistribution.

Extended EVM Compatibility (April 2025)

• Developers can now deploy standard Ethereum smart contracts without additional adaptations.
• Greater integration with tools like Hardhat, Foundry, and MetaMask.

Strategic goals for 2025

The zkSync team has set ambitious objectives to shape the future of its ecosystem:

• Surpass 10,000 TPS (transactions per second) to compete with traditional solutions and newer Layer 1 chains.
• Lower transaction fees to USD 0.0001, democratizing access to DeFi and NFTs.
• Enhance privacy and security through stronger ZK proofs and confidential computation models.

Implications for developers and users

These enhancements aim not only to relieve congestion but also to expand zkSync’s appeal as a development platform:

• Lower latency and improved end-user experience.
• Incentives to build more sophisticated dApps without exceeding gas budgets.
• Easier migration for existing projects from Ethereum or other Layer 2 chains.

zkSync is positioning itself as a key pillar in Ethereum’s new era of scalability. Its technical approach and long-term vision could mark the beginning of a more efficient and accessible blockchain infrastructure for everyone.
