Question 1

What is zkSync (ZK)?

Accepted Answer

zkSync (ZK) is a layer 2 scaling solution for Ethereum designed by Matter Labs. It leverages zero-knowledge rollups (zk-rollups) to enhance transaction throughput and reduce costs while maintaining security and decentralisation. By aggregating multiple transactions into a single proof, zkSync significantly decreases the data load on the Ethereum mainnet, resulting in lower transaction fees and faster processing times. zkSync aims to provide a scalable, efficient, and user-friendly platform for Ethereum users and developers.

Question 2

What is zkSync (ZK) used for?

Accepted Answer

zkSync (ZK) is used for various purposes within the Ethereum ecosystem, including:

1. **Transaction Scaling:** By batching transactions into a single proof, zkSync enables higher transaction throughput and lower fees compared to the Ethereum mainnet.
2. **Decentralised Finance (DeFi):** It supports DeFi applications, facilitating activities like trading, lending, and borrowing with improved efficiency and reduced costs.
3. **NFT Marketplaces:** zkSync's low fees and fast transactions make it suitable for NFT minting, buying, and selling, enhancing the user experience.
4. **Payments:** The platform supports cost-effective micropayments, making it ideal for applications requiring frequent small transactions, such as subscriptions and in-app purchases.
5. **Token Transfers:** zkSync allows for quick and inexpensive ERC-20 token transfers, benefiting overall network usability.

Question 3

Who created zkSync (ZK)?

Accepted Answer

zkSync was developed by Matter Labs, a company focused on solving Ethereum’s scalability issues through advanced cryptographic techniques. The key members of the Matter Labs team include:

- **Alex Gluchowski:** Co-Founder and CEO
- **Zoé Gadsden:** Chief Operating Officer (COO)
- **Anthony Rose:** Chief Technology Officer (CTO)
- **Geoffrey Thompson:** General Counsel

Question 4

How does zkSync (ZK) work?

Accepted Answer

zkSync employs a zk-rollup mechanism to achieve scalability. The process includes:

1. **Batching Transactions:** Multiple transactions are grouped into a batch off-chain.
2. **Generating Proofs:** A cryptographic proof, known as a zk-SNARK, is generated for the batch, certifying the validity of all transactions within it.
3. **On-Chain Verification:** This proof is then submitted to the Ethereum mainnet, where it is verified, ensuring all transactions are correct.
4. **State Updates:** Upon verification, the Ethereum mainnet updates its state to reflect the batched transactions.

This method significantly reduces the data that needs to be processed on-chain, thus lowering fees and increasing throughput.

Question 5

Security and Decentralisation

Accepted Answer

zkSync maintains high security and decentralisation standards by adhering to Ethereum’s security model. The use of zk-rollups ensures that transactions are cryptographically verified before being included on-chain, eliminating the need for trusted intermediaries. This approach preserves Ethereum's security guarantees while enabling higher transaction capacity and lower costs.
