Loopring is a decentralised trading protocol built on the Ethereum blockchain. It leverages a technology known as Zero-Knowledge Rollups (zk-Rollups) to address the limitations of traditional and decentralised exchanges by providing an interoperable, efficient, and secure trading platform. The protocol is non-custodial, meaning users retain control over their assets, and it supports features like high throughput, low transaction costs, and off-chain order matching.
Loopring operates using Zero-Knowledge Rollups (zk-Rollups), which enable the protocol to bundle transactions off-chain and settle them on-chain, ensuring high transaction speeds and reduced costs. This technology enhances scalability while maintaining security and decentralisation. Loopring smart contracts on Ethereum manage trading rules and liquidity aggregation, ensuring secure and efficient exchanges. The system verifies transactions using zk-SNARKs, specifically the Groth16 proving system, ensuring that each transaction update is valid.
Loopring can be used in various sectors, such as:
Moreover, Loopring has partnerships with companies like Changelly for trading integration and Chainlink for oracle services, demonstrating its broad applicability within the DeFi ecosystem.
Loopring was founded in 2017 by Daniel Wang. It began with an ICO that raised $45 million worth of Ethereum. The protocol initially intended to expand on NEO and QTUM networks but later focused solely on Ethereum. Over the years, Loopring has released several updates, with the latest being Loopring 3.8, featuring advancements like zk-Rollup integration for high-speed transactions. Its market presence expanded with the launch of Loopring.io in 2020, a platform that blends AMM and order-book models. Efforts like integrating with Google Cloud and initiatives like Loopring Gaming highlight its continuous evolution and commitment to scalability and security.
