What is zkSync?
zkSync is a Layer 2 protocol built on zk-Rollup technology, offering scalable and low-cost payments on Ethereum. It combines zk-Rollup and zkPorter to achieve optimal security while drastically reducing transaction fees. Currently, zkSync handles 20,000 TPS, with plans to exceed 100,000 TPS in its upcoming 2.0 release.

How Does zkSync Work?
What Are Rollups?
Rollups bundle transactions off-chain and submit proofs to Ethereum for validation. Two primary types exist:
- Optimistic Rollups: Assume validity unless challenged.
- zk-Rollups: Use cryptographic proofs (SNARKs) for instant validation.
zk-Rollups Explained
zk-Rollups process transactions off-chain, generating a SNARK proof to validate data without revealing details. This proof is submitted to Ethereum, ensuring:
- Lower gas fees (storage happens off-chain).
- Faster processing (10x more efficient than Optimistic Rollups).
Using zkSync
- Connect Your Wallet: Use MetaMask or other supported wallets.
- Deposit Funds: Transfer ETH or tokens via exchanges/bridges.
- Transact: Send tokens with minimal fees (payable in ERC-20 tokens).
zkSync Ecosystem Drivers
Top Projects
- SyncSwap: Decentralized exchange with efficient swaps.
- ZeroLend: Largest lending market on zkSync.
- Maverick: Low-cost liquidity solutions.
- Tevaera: Multi-genre gaming platform.
Bridges
- ZKsync Portal Bridge: Secure asset transfers between Ethereum and zkSync.
- Orbiter Finance: Cross-chain rollup protocol.
Paymasters
Special accounts that subsidize transaction fees, enabling gasless transactions via ERC-20 tokens.
FAQ
Is zkSync secure?
Yes! zk-Rollups use advanced cryptography to maintain Ethereum-level security.
How do zk-Rollups compare to Optimistic Rollups?
zk-Rollups are faster, cheaper, and more scalable due to SNARK proofs.
Can I use zkSync for DeFi?
Absolutely. Projects like SyncSwap and ZeroLend are already live on zkSync.
Conclusion
zkSync is revolutionizing Ethereum scalability with its zk-Rollup technology, offering 20,000+ TPS, low fees, and robust security. As adoption grows, zkSync is poised to become a cornerstone of Layer 2 solutions, enabling seamless DeFi, gaming, and cross-chain interoperability.
