The ZKstack Atlas Upgrade Atlas isn’t just another upgrade, it’s what connects the entire @zksync OS together, making it easier for developers to build, deploy and scale modular ZK chains that actually talk to each other. It's the framework that makes rollups more flexible, more efficient and more interoperable, while keeping everything aligned with Ethereum’s core principles. To me, Atlas feels like the turning point where ZKsync moves from being a rollup to becoming an ecosystem builder for the next phase of Ethereum scaling. We’re not just talking performance, we’re talking maturity for the whole ZK ecosystem.
