Zero Knowledge Rollups

Zero-Knowledge (ZK) rollups represent an advanced cryptographic technique ensuring transaction validity through minimal information, thus prioritizing privacy without compromising on speed or cost-efficiency. Unlike Optimistic rollups, which necessitate a holding period for funds pending dispute resolution, ZK-rollups facilitate quicker access to withdrawn funds. This method employs sophisticated ZK-proof cryptography to achieve its objectives, making it a superior choice for enhancing transaction privacy and efficiency.

ZK-rollups offer superior speed and security compared to Optimistic rollups, though they are significantly more complex. Currently, existing ZK-rollups are designed for specific functions, such as NFT swaps or cryptocurrency transfers, limiting their versatility.
