We are getting close to deploying Loopring 3.0 on Ethereum mainnet. The Lightcone relayer is also making significant progress.

All our blog posts and updates are also released on https://loopring.org.

Research & Development


We made a change to how ring-settlements are validated in the circuits. This change increases the flexibility of the protocol, giving the relayer a lot more freedom in how and in what sequence orders can be matched. Of course, we still enforce the requirements as specified in the order.

Work was finished on the software needed to run phase 2 of the trusted setup. Phase 2 builds on phase 1 of the trusted setup, but phase 2 is, in contrast to phase 1, circuit-specific. Both phases of the trusted setup are needed to make sure our circuits are secure. A lot of code for doing the trusted setup already exists for Bellman, and we wanted to make use of that. We decided to make some minor changes to libsnark/ethsnarks so that the data generated by the Bellman trusted setup code is compatible with our libsnark code. Once we got that working, we kicked off the Loopring’s phase 2 ceremony which is specifically for the circuits we need in protocol v3. Five people have already contributed, and more people are scheduled to participate in the coming weeks!

We also started work on a tailored smart wallet for use with Loopring v3 exchanges. More details will be shared about this once we’re further along in development.

SECBIT has delivered its security audit report for Loopring 3.0. Our engineers have studied the report and improved the protocol based on the findings in the report. More information regarding the report will become available next week.

With the completion of the third-party security audit, we only need to wait for five more people to finish their trusted setup MPC computation before we can deploy the protocol to Ethereum mainnet.

We are almost there…

Lightcone Relayer

The relayer team has completed a third major infrastructure refactoring, the last one before the initial launch. They are testing the integration of sub-modules and adding more tests. The overall progress is in sync with our schedule.

A new fee management module is also code-complete. The module will support fee configuration for each account. The team has also adopted the Service Mash technology to balance load among multiple microservices of the same type.

After this refactoring, Lightcone’s reliability and performance will be noticeably improved. The relayer cluster will also support users to make deposits immediately after submitting account creation requests without any waiting. The average deposit-handling time will likely halve.

The team has added alarm monitoring on the VM level, the process level, and the log level; they have also enabled push notifications through Alibaba’s DingDing service.

DEX Frontend

We have enabled the web app to fetch specific data through WebSocket and added multiple-language support.

Note: Web-based app development is no longer our focus. WE’ll, however, provide technical consulting and support to WeDEX and other future partners.
