zkSync is Matter Labs' open-source ZK Rollup technology for scaling and adding privacy to Ethereum, including the ZK Stack framework for launching custom ZK chains, the Prividium private/permissioned rollup, and the Airbender RISC-V prover. This repository historically contains the ZKSync Lite (formerly zkSync 1.0) core, which is now deprecated, with the project's active development focused on the broader ZKsync protocol ecosystem.

Use cases

• scale ethereum transactions with zero-knowledge rollups
• launch a custom zk rollup chain on ethereum
• generate withdrawal proofs for deprecated zksync lite funds
• build privacy-preserving institutional blockchain applications
• prove rust or risc-v programs with a fast zkvm
• run low-gas eth and erc20 transfers on layer 2

When to choose

• you need zk rollup scaling or privacy for ethereum applications
• you want to launch a customizable app-chain inheriting ethereum security
• you need to independently withdraw funds from the deprecated zksync lite
• you need a high-performance open-source zk prover for risc-v programs

When to avoid

• you need a general-purpose blockchain unrelated to ethereum or zk proofs
• you want to build new functionality on zksync lite, which is deprecated
• you need a simple smart contract wallet without layer 2 infrastructure
• you cannot operate gpu or specialized proving infrastructure
