In the context of digital currencies, what are the main differences between zk and optimistic rollup?
2 answers
- Dec 26, 2021 · 3 years agozk rollup and optimistic rollup are both scaling solutions for digital currencies, but they differ in their approach to transaction verification. Zk rollup uses zero-knowledge proofs to bundle multiple transactions into a single proof, while optimistic rollup assumes transactions are valid and only challenges them if proven otherwise. Zk rollup offers stronger privacy and scalability, but optimistic rollup is more lightweight and flexible. Both solutions have their advantages and are being actively explored and implemented in the digital currency space.
- Dec 26, 2021 · 3 years agoIn the context of digital currencies, zk rollup and optimistic rollup are two different approaches to scaling and improving transaction throughput. Zk rollup uses zero-knowledge proofs to bundle multiple transactions into a single proof, which is then verified on the main chain. This approach ensures privacy and scalability but requires more computational resources. On the other hand, optimistic rollup assumes transactions are valid by default and only challenges them if necessary. This reduces the computational overhead but introduces a small possibility of fraud. Both zk rollup and optimistic rollup have their advantages and trade-offs, and their suitability depends on the specific needs of the digital currency ecosystem.
