Bi-Weekly

The last two weeks have been super exciting for us: Loopring 3.0 beta4 will finally complete deployment early next week. Loopring will be Ethereum’s first zkRollup DEX protocol enforcing on-chain data availability. We are ready to roll!

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

We have been preparing the multiparty computation ceremony required for Loopring 3.0’s trusted setup. We have completed and are testing the code for our ceremony (a.k.a., phase 2),

We’ve been at Ethereum Devcon in Osaka, continued protocol and Lightcone development, as well as a slew of operations activities.

We have been testing the Lightcone relayer cluster, and identifying and fixing bugs. Lightcone’s integration testing and stress testing will remain our top priority in the coming months.

Happy Mid-Autumn Festival! We hope you have enjoyed some delicious mooncakes.

Over the past two weeks, we have been testing the off-chain proof generation performance and cost, and have achieved very satisfactory results. We have also been busy in Berlin with Blockchain Week, learning from the great ecosystem there, and sharing Loopring developments in some talks.

Loopring v3 beta3 has been deployed on Ethereum mainnet. We have made another 15% TPS improvements from the last update and we expect the throughput without data availability to break 10,000 TPS after Istanbul fork. The v3 smart contract & ZKP circuit audits have begun by SECBIT team.

We have completed all planned features in the Loopring v3 beta3 release, including a much-simplified fee model to reduce the constraints in the settlement circuit, and an address whitelist mechanism to support customizable whitelisting logics.

We started to develop the beta3 version of the Loopring Protocol 3.0, which will greatly increase the throughput and reduce the cost per settlement. We are excited to share some preliminary results in this bi-weekly update.

Last week we released the second beta of Loopring 3.0 — beta2. This version has been repeatedly tested and is very stable. In the coming week, we will release a bug bounty for this.

Starting next week, Loopring will shift its engineering focus from protocol development to relayer development to ensure the launch of our first v3 public beta in Q4, 2019.

We managed to complete the development of a new fee model and further optimize the throughput of our zero-knowledge proof-based Loopring protocol and made remarkable progress on the relayer implementation.

We are doing something wonderful with Loopring v3.We have been working on a new fee model and a staking system for Loopring v3. These are being developed specifically for the strength of Loopring v3.

Major protocol 3.0 improvements, LRC token contract upgrade completed, and Blockchain Week New York kicks off.

We open-sourced the Lightcone relayer — a Loopring backend matching system. A relayer is the off-chain component that hosts orders, matches them, and submits them to the Loopring protocol smart contracts for settlement.

We released Loopring Protocol 3.0! Using zkSNARKs to achieve much higher throughput of 450 trades/second on Ethereum without on-chain data availability, and 80 trades/second with on-chain data availability. Past versions of Loopring achieved only ~2 trades/second!

We have made excellent progress on Loopring 3.0, Oedax, and Lightcone relayer implementation. We’ll open source all of them soon in Q2.
