Key Takeaways
- ZKsync is a Layer-2 scaling solution for Ethereum, leveraging zero-knowledge rollups (zk-rollups) and zero-knowledge proofs (ZKPs) to enhance transaction speed and reduce costs.
- The ZKsync airdrop allocated 17.5% of its total token supply to active users and ecosystem contributors.
- Compared to optimistic rollups, ZKsync offers superior security and faster transaction settlements due to its cryptographic proofs.
Introduction
Blockchain scalability remains a critical challenge, often causing slower transactions and higher fees as networks grow. Zero-knowledge (ZK) technology presents a viable solution. This article explores ZKsync’s architecture, its advantages over optimistic rollups, and its native ZK token distribution.
What Is ZKsync?
ZKsync is an Ethereum Layer-2 protocol that processes transactions off-chain using zk-rollups, bundling them into batches for efficiency. Think of it as adding an express lane to a congested highway—relieving pressure on Ethereum’s mainnet while maintaining security.

How Does ZKsync Work?
1. Transaction Aggregation
ZKsync batches hundreds of transactions off-chain, minimizing Ethereum’s workload.
Example: Like a postal service bundling letters for bulk delivery instead of handling each individually.
2. Zero-Knowledge Proofs (ZKPs)
Each batch is validated via ZKPs, which confirm transaction validity without revealing details.
Analogy: Proving you know a password by answering questions—without ever saying the password itself.
3. On-Chain Verification
Proofs are submitted to Ethereum for final approval, ensuring tamper-proof record-keeping.
ZK Token: Governance and Utility
- Governance: Holders delegate voting power to influence protocol upgrades.
- Delegation: Tokens can be assigned to any address (self or third-party) to activate voting rights.
Note: ZK tokens launched on Binance on June 17, 2024, with a seed tag for early adopters.

FAQs
1. How do I check my ZKsync airdrop eligibility?
Visit the official claim site and enter your wallet address.
2. What’s the difference between zk-rollups and optimistic rollups?
ZKsync uses ZKPs for instant finality; optimistic rollups rely on dispute periods.
3. Can I delegate ZK tokens to multiple addresses?
No—delegation is per-wallet and non-splittable.
4. Why was the ZKsync airdrop controversial?
Critics cited insufficient Sybil attack prevention and unequal distribution.
5. Is ZKsync secure?
Yes—its ZKP-based validation ensures tamper-proof transactions.
Conclusion
ZKsync combines ZK technology and EVM compatibility to scale Ethereum efficiently. With faster settlements than optimistic rollups and a community-driven airdrop, it’s a standout Layer-2 solution.
