zk Rollups and Optimistic Rollups are both scalability solutions for blockchain networks, designed to improve transaction throughput and reduce costs.
zk Rollups (Zero-Knowledge Rollups) aggregate multiple transactions into a single proof, known as a zero-knowledge proof, which is then verified on the main chain. This approach ensures high security and privacy, as the proof validates all transactions without revealing their details. zk Rollups offer immediate finality and lower latency, making them ideal for applications requiring high confidentiality and efficiency.
Optimistic Rollups aggregate transactions off-chain and submit a batch to the main chain with an assumption of correctness. Any disputes are resolved through a challenge period where incorrect transactions can be contested. This method can be more flexible and easier to implement but involves a delay due to the challenge period, potentially impacting finality and transaction speed.
Both solutions enhance scalability but differ in their approaches to security and transaction finality.
