Research & Development

Loopring Protocol v3

We added improvements to protocol 3 that further reduces the data we have to send on-chain for data availability. In the circuits, we first transform the data into a format that can be compressed more easily. The data can then be compressed and sent on-chain. Our smart contract decompresses the data to make sure all necessary data is still available. How much this reduces the gas usage depends on the data and this will be further improved by optimizing the off-chain compressor and the on-chain decompressor (which can be versioned and upgraded without any changes to the protocol) and by optimizing for realistic data patterns. We expect this feature to improve the throughput with data availability even further.

We also did some improvements to the maintenance mode to provide more flexibility for the exchange owner and fixed a potential problem with the automatic distribution of tokens when token transfer consumes an unreasonable amount of gas.

Lightcone Relayer v2

We have completed all modules for an MVP that supports Loopring 3.0 (beta1) and have identified several areas for improvements. We have also begun to refactor code and design a production-ready architecture. We expect the new architecture will be ready in about two weeks after several scheduled brainstorming sessions among our backend engineers and technical advisors.

We are grateful for having help from Chao Ma, the former head of engineering at Alipay International. His expertise and experience are remarkable and his advice and feedbacks to our relayer design are exceptional.

Products

We have finished the majority of UI layout and styling for our DEX web app. We’ll start to code interactions by using a mock API service in the coming weeks.
