ZKsync
ZKsync is a network of interoperable ZK Rollup chains providing scalable, privacy-preserving, and compliant blockchain infrastructure secured by cryptography.
Overview
ZKsync is a Layer 2 scaling and privacy solution built on zero-knowledge (ZK) rollup technology that inherits Ethereum's security guarantees. It enables businesses and developers to launch customizable, interoperable blockchains with cryptographic security, privacy, and compliance features. The platform supports both public and private chains connected through a shared Ethereum bridge, allowing seamless asset transfers and real-time settlement with low latency and high throughput. ZKsync's architecture ensures that funds are secured by smart contracts on Ethereum while computation and storage occur off-chain, validated by succinct zero-knowledge proofs.
The platform targets enterprises, financial institutions, and developers seeking scalable blockchain infrastructure with privacy and regulatory compliance. Key components include ZK Stack, an open-source framework for building enterprise-grade ZK blockchains; Prividium, a private permissioned ZK-Rollup designed for institutions requiring privacy and control; and ZKsync Connect, an interoperability protocol enabling atomic, privacy-preserving settlement across public and private systems. ZKsync also features Airbender, a high-performance RISC-V prover that delivers subsecond block proofs and low transaction costs.
Developers can build on ZKsync using standard Ethereum tools like Solidity, Hardhat, and Foundry without rewriting code. The platform offers modern onboarding primitives such as passkeys, smart accounts, and gasless transactions to improve user experience. ZKsync provides production-ready infrastructure with metrics, logs, tracing, and options for managed or self-hosted deployments. Its open-source codebase is extensively audited and battle-tested, supporting millions of zero-knowledge proofs in production. Adoption includes over 18 chains in the network, $4 billion+ total value locked (TVL), and 700 million+ transactions processed. Notable integrations include Deutsche Bank, UBS, Abu Dhabi Investment Authority, and tokenization platforms managing billions in assets.
To get started, developers can access comprehensive documentation, SDKs in JavaScript and Rust, and local development environments. The platform encourages collaboration through GitHub discussions, Discord, and community forums. Enterprises can engage with ZKsync's expert team for strategy, compliance, and deployment support to accelerate blockchain initiatives.
The Problem
Traditional blockchain networks face challenges scaling to meet enterprise demands for privacy, compliance, and high throughput. Existing Layer 2 solutions often lack interoperability, regulatory controls, or impose trust assumptions that limit institutional adoption.
The Solution
Key Features
ZK Rollup architecture
Off-chain computation with on-chain validity proofs ensures security and scalability without sacrificing decentralization.
Airbender prover
High-frequency, low-latency zero-knowledge proof generation enabling subsecond block finality and low transaction costs.
ZKsync Connect interoperability protocol
Atomic, privacy-preserving settlement across public and private blockchains to increase capital efficiency and reduce counterparty risk.
