zkSync: The First EVM-Compatible zkRollup Protocol

zkSync is a trustless protocol for scalable low-cost transactions on Ethereum. It's also the only zkRollup protocol which supports EVM smart contracts. Alex Gluchowski is co-founder of Matter Labs, and co-creator of zkSync. We spoke with Alex in depth about how the protocol works and the potential for a highly scalable transaction and application layer on Ethereum.

Topics:

• Alex's background and how he got into the crypto space
• An overview of existing Ethereum scaling solutions
• Difference between Optimistic Rollup and zkRollup
• Transferring funds to the zkSync Layer 2 and gas fees involved
• How the zkSync transaction sequencer works
• Withdrawing funds to Layer 1 and timescales involved
• How the procol deals with reorgs
• How block formation works on zkSync
