zkSync Era: Zero-Knowledge Proofs for Ethereum Scaling
Learn about zkSync Era, a ZK rollup that offers Ethereum security with dramatically lower costs.
What Is zkSync Era?
zkSync Era is a Layer 2 ZK rollup built by Matter Labs. It uses zero-knowledge proofs to verify transaction batches, offering stronger security guarantees than optimistic rollups while maintaining EVM compatibility.
ZK vs. Optimistic Rollups
- Finality: ZK rollups have faster finality (no 7-day challenge period)
- Security: Mathematical proofs vs. fraud proofs
- Cost: ZK proof generation adds overhead but is improving rapidly
- Compatibility: zkSync supports most Solidity code with minor differences
Ecosystem
SyncSwap, Mute.io, SpaceFi, and ZKSwap are leading DEXs. The ecosystem is growing with DeFi, NFTs, and account abstraction use cases.
Account Abstraction
zkSync has native account abstraction (AA), enabling features like gasless transactions, social recovery, and batch operations — features that significantly improve user experience.
