zkSync vs Optimism?
part 2

2. Transaction Finality:
zkSync: Transactions are validated quickly because ZK-proofs ensure instant finality on-chain.

Optimism: Transaction finality takes longer due to a 7-day challenge period to allow for fraud disputes.
3. Security:

zkSync: Provides instant and secure verification through ZK-proofs, with no need for challenge periods.
Optimism: Relies on the fraud-proof mechanism, meaning security is delayed during the challenge window.
4. Cost:

zkSync: Typically offers lower transaction fees due to its highly efficient proof system, though ZK-Rollups are more complex to implement.
Optimism: Has lower fees than Ethereum Layer 1, but may be slightly higher than zkSync due to on-chain data posting requirements.

zkSync stands out with its instant transaction finality thanks to ZK-proofs, providing security without delay. On the other hand, Optimism introduces a 7-day challenge period for transaction finality, potentially impacting security. When it comes to cost, zkSync generally offers lower fees, while Optimism, although cheaper than Ethereum Layer 1, may have slightly higher fees due to on-chain data posting. Choose wisely based on your priorities!
