Daniel Wang: Loopring – A Scalable DEX Protocol Using ZK-Rollups

Decentralized exchanges have been around for some time, and various designs have been attempted. Although they provide a number of privacy and censorship resistance benefits, one of their pitfalls has been transaction throughput. However, recent advancements in Zero-Knowledge Proof-based scaling solutions is creating a new breed of scalable DEXes.

Loopring is a non-custodial DEX protocol that achieves high-throughput trading. It leverages ZK-Rollups to achieve upwards of 2,000 transactions per second with on-chain settlement. As an order book-based exchange, it sets itself apart from other DEXes like Uniswap and the Gnosis Protocol. However, users should keep in mind that the orderbook is centralized. Daniel Wang, Founder & CEO of Loopring, talks about why they decided to focus on DEXes and their plans beyond the current version 3.0.
