ZKsync Era: A ZK Rollup For Scaling Ethereum

ZKsync Era is a layer 2 rollup that uses zero-knowledge proofs to scale Ethereum without compromising on security or decentralization. Since it's EVM compatible (Solidity/Vyper), 99% of Ethereum projects can redeploy without refactoring or re-auditing a single line of code. ZKsync Era also uses an LLVM-based compiler that will eventually let developers write smart contracts in C++, Rust and other popular languages.

Disclaimer

ZKsync Era has been through lots of testing and audits. Although it is live, it is still in alpha state and will go through more audits and bug bounty programs. We would love to hear our community's thoughts and suggestions about it! It is important to state that forking it now can potentially lead to missing important security updates, critical features, and performance improvements.

lib.rs:

ZK Stack node initialization framework.

This crate provides core abstractions that allow one to compose a ZK Stack node. Main concepts used in this crate are:

• WiringLayer - builder interface for tasks.
• Task - a unit of work that can be executed by the node.
• Resource - a piece of logic that can be shared between tasks. Most resources are represented by generic interfaces and also serve as points of customization for tasks.
• ZkStackService - a container for tasks and resources that takes care of initialization, running and shutting down.
• ZkStackServiceBuilder - a builder for the service.
