What is ZKsync?
ZKsync is a zkRollup on Ethereum that proves every operation with zero-knowledge proofs. Fees depend on L1 gas prices because pubdata is published to Ethereum. Batches wait an execution delay of at least 3 hours, cut from 21 hours by ZIP-4, so full finality is about 3 hours.
ZKsync pros and cons
- Full finality in about 3 hours, not 7 days
- Execution delay gives time to freeze the protocol if a bug is exploited
- Node code public under Apache-2.0
- Opcode pricing differs from Ethereum, e.g. keccak256 costs more
- L2 fees move with volatile L1 gas prices
- Validator role is controlled by the team behind a time lock
