Overview

• ZKsync rolled out the Atlas upgrade to its ZK Stack on October 6, positioning it as production-ready infrastructure.
• Atlas integrates the Airbender proving system to provide sub-second confirmations targeting roughly one-second finality.
• A new high-performance sequencer is rated for 25,000 to 30,000 transactions per second to overcome throughput bottlenecks.
• The upgrade supports semi-public enterprise chains that remain Ethereum-compatible, enabling private control alongside access to public liquidity.
• Following the announcement, the ZK token gained about 7% intraday and over 20% on the week, as the team highlighted prior security hardening after a roughly $5 million breach and ecosystem growth that includes co-leading a $19 million round for Grvt.
