ZK STACK'S ATLAS UPGRADE

Summary from the TLDR Crypto newsletter

ZKsync's Atlas upgrade for ZK Stack features a high-performance sequencer that achieves over 15,000 TPS with 500ms average transaction inclusion time, integration with Airbender (the world's fastest open-source RISC-V zkVM) for one-second block proofs, and native EVM support through a flexible architecture that allows multiple VM configurations. Performance benchmarks show 23,000 TPS for high-frequency oracle price updates, 15,000 TPS for stablecoin transfers at 0.5 gigagas per second, and 43,000 TPS for native ETH transfers at 0.9 gigagas per second, with proving costs dropping to approximately $0.0001 per ERC20 transfer. The upgrade enables one-second ZK finality where blocks are proved and verified by ZKsync Gateway at the network edge before settling to Ethereum within minutes, allowing counterparties to receive cryptographic execution assurance almost immediately without re-executing transactions or running full nodes. This architecture supports the vision of many sovereign chains forming a secure network where banks, enterprises, and public agencies operate private blockchain infrastructure while participating in an incorruptible network anchored to Ethereum's security and liquidity.
