In the world of cryptocurrency, layer-2 scaling solutions act as essential partners to congested blockchains, addressing high costs and inefficiencies. This dynamic defines the relationship between Ethereum and its underlying network, zkSync.
But what is zkSync beyond the hype? How does it function, and is it truly the revolutionary layer-2 solution it’s touted to be? Let’s explore.
The Origins of zkSync
Launched in 2020 by co-founders Alex Vlasov and Alex Gluchowski, zkSync began as a project rooted in mathematics, blockchain liberty, and engineering. The team spent three years developing zkSync 1.0, followed by zkSync 2.0 (dubbed "baby-alpha") two years later.
Today, over 100 projects operate within its ecosystem, leveraging its ZK-rollup technology for faster, cheaper transactions.

Is zkSync a Blockchain?
No—zkSync is a layer-2 protocol, not a standalone blockchain. It functions as a scalability enhancer for Ethereum, processing transactions off-chain before bundling them into a single proof for the mainnet. Think of it as a high-speed train running parallel to Ethereum’s highway.
How Does zkSync Work?
zkSync relies on ZK-rollups (Zero-Knowledge rollups) to:
- Batch transactions off-chain.
- Generate cryptographic proofs (SNARKs/STARKs).
- Submit proofs to Ethereum for verification.
Unlike Optimistic Rollups (which assume transactions are valid unless challenged), ZK-rollups prove validity instantly, reducing delays and costs.
Key Advantages of ZK-Rollups
✅ Lower fees (up to 100x cheaper than Ethereum).
✅ Faster throughput (~3,000 TPS).
✅ Enhanced security (Ethereum-level finality).
Benefits of zkSync
1. Reduced Gas Fees
Transactions cost fractions of a cent, making microtransactions viable.
2. High-Speed Transactions
Processes thousands of TPS vs. Ethereum’s ~15 TPS.
3. Multi-Token Fee Payments
Pay fees in ETH, USDC, or other supported tokens.
4. Seamless Bridging
Use the zkSync Era Bridge to transfer assets between Ethereum ↔ zkSync.
5. Scalability
Supports mass adoption for dApps, DeFi, and NFTs.

Challenges & Drawbacks
1. Technical Complexity
ZK-proofs require advanced cryptography, posing a learning curve for developers.
2. Controversies
Critics highlight concerns over centralization risks and governance token distribution.
3. Unique Programming Language
Developers must learn Zink, diverging from Ethereum’s Solidity.
How to Use zkSync
- Set Up a Wallet (MetaMask, Trust Wallet).
- Bridge Assets via the official zkSync bridge.
- Interact with dApps (SyncSwap, CrowdSwap, etc.).
zkSync on CrowdSwap
CrowdSwap has integrated zkSync to offer:
- Cross-chain swaps.
- Liquidity farms (e.g., CROWD/ETH).
- Decentralized exchanges (CrowDEX, SyncSwap).
The merger unlocks lower fees, faster trades, and expanded DeFi opportunities.
Final Takeaways
zkSync is a game-changer for Ethereum, delivering:
✔ Cheaper transactions.
✔ Blazing-fast speeds.
✔ Scalability for Web3.
As adoption grows, expect more dApps, bridges, and innovations to emerge.
