Loopring Bi-Weekly Update — 12/22/2018

Our security audit for Loopring Protocol 2.0 has successfully completed, and we have deployed 2.0! We will publish a separate post reviewing all of 2.0 functionality shortly. Our mobile apps saw meaningful updates, including a contact list for addresses. These past 2 weeks also saw a few updates on how Loopring is working with cross-chain projects for interoperability.

Protocol

The security audit for protocol 2.0 is complete. The report can be found here: (http://loopring.org/resources/loopring_protocol_v2_audit_report_EN.pdf).

Shortly afterwards, we deployed protocol 2.0 to main net (https://github.com/Loopring/protocol2/blob/23bbb4e567d0ae32bf370c86a061d7adf145782a/deployment.md)!

In the coming days, we will provide an overview of exactly what 2.0 enables — from a technical POV, as well as a feature and user-facing POV.

The bug and optimization bounty program we launched in late October ended. We approved one optimization proposal that gave a minor reduction in gas consumption.

We finished work updating our code base to Truffle 5.0 with solidity 0.5 and web3 1.0. The final release version of Truffle fixed all stability issues we had with the beta releases.

We also continued our research for the next protocol release (more information will be released shortly in our updated 2019 roadmap).

Relay

Lightcone (Relay 2.0)

We have completed the first stage of our Lightcone Relay roadmap.

It includes submitting orders, canceling orders, matching orders, order book, trade history and other critical components. We have spent time on testing the relay to improve quality and performance. In addition, we have implemented JSON RPC. We have also modularized Ethereum interface to make it easy to use in the client.

Our new relay architecture is shaping up to be a formidable piece of our puzzle, and we are optimistic it will be a differentiator among DEXs, more closely emulating CEX performance.

Frontend & Product

iOS & Android

We have implemented the same features in the iOS and Android apps over the past two weeks, so we’ll combine the developments into one section this time.

After working with SECBIT for a long time, we have completed the security audit of the iOS and Android apps. The audit covered three areas, (1) common risks in application, (2) digital wallet assets security, (3) server-side application security.

The assessment has shown that our apps have no critical security risks. Even if an Android phone grants root access, our Android app can still provide good security protection. Audit reports are posted here:

https://loopring.org/resources/Loopr_Android_Security_Audit_Report_EN.pdf(Android English)

We have implemented a contacts feature where users can store Ethereum addresses corresponding to their friends and peers. Users can add a name and note to each address. It makes it much easier for users to manage addresses. Users can also search addresses by name and note in the contact list view.

Another important feature is that users can now claim LRN airdrop in the homepage every day.

We have also improved many UI components. One of them is the new ‘version release’ notification being displayed when a new version of the app is released. You don’t have to get notifications from social media anymore.
