After 3 months of building, we are excited to release an upgraded version of the Scroll Pre-Alpha Testnet. Our previous version onboarded over 10k users to test our bridge and demo forks of dapps like Uniswap. We'd like to thank the community for their helpful feedback on our UI/UX, and we are working hard to scale up our proving infrastructure to support the 100K+ users on our waitlist.

Scroll is an EVM-equivalent zkRollup to scale Ethereum. Technically speaking, Scroll is built upon two major pieces. The core piece is the zkEVM, which is used to prove the correctness of EVM execution in Layer 2. We have been building it in the open with the Privacy and Scaling Explorations group at the Ethereum Foundation for over a year. But to turn the zkEVM into a full zkRollup on the Ethereum, we also need to build a complete L2 architecture around it.

To scale Ethereum with our zkEVM-based zkRollup, we have designed Scroll based on a set of technical principles which uphold Scroll's core values. This post lays out these principles and how they relate to our broader design for Scroll.

After over a year of building our zkEVM-based zkRollup in close collaboration with the PSE (Privacy and Scaling Explorations) group at the Ethereum Foundation, we are releasing the pre-alpha version of Scroll for external testers! In the spirit of building in the open with the community, we have prioritized getting community feedback quickly with this initial release.

We believe that decentralized computing platforms will play a crucial role by upholding and promoting principles representing the broader community.
