Composability between Ethereum Layer 1 and 2

Onchain composability with layer 2 solutions poses some challenges. Doing things offchain is great for scalability, but how do you connect onchain interactions with offchain logic? We want our ZK Rollup exchanges to be part of the composable Ethereum ecosystem.

Loopring and Chainlink Fireside Chat

Last week, Loopring’s Chief Architect, Brecht Devos, sat down to chat with Chainlink’s Johann Eid and Rory Piant in a live video chat. They spoke about ZK Rollups, DEX scaling, and the use of Chainlink oracles to secure a component of LRC staking. The video can be found here.

Loopring Testing Phase 1: Data Recap

On December 18, 2019, we started to work with WeDEX to test the integration of Loopring Protocol v3, the Lightcone relayer, and WeDEX’s front-end on Ethereum mainnet. This is the deep dive data and analysis.

Chainlink and Loopring Collaborate on Oracles for zkRollup DEX Protocol

Chainlink and Loopring are pleased to announce our collaboration across several oracle integrations in Loopring’s v3 zkRollup DEX protocol. The first of which is live on Ethereum mainnet: a faithful LRC/ETH price feed for DEX owners to anchor their LRC economic security staking.

Loopring 2020 Development Roadmap

As each year draws to a close, Loopring releases the R&D roadmap for the coming year. This supports transparency and allows the community to obtain a greater understanding of the plan. Equally important, it forces us to think hard about the future and to reach consensus on the plan.

LRC Opens Golden Staking Window

Loopring Foundation is staking its own LRC. We’ve created a “golden staking window” which opens now and will close at the end of January of 2020. This window can be beneficial to LRC holders.

We Take 'The Ultimate Non-Custodial Test'

Our foremost duty is towards user sovereignty & security — ensuring that Loopring-based DEXes can never access user funds, nor prevent users from accessing their own funds. Even if Loopring (the team, the foundation, anything) shut down or became malicious, it would not matter.

DEXes Rising: Next Chapter, High Performance Orderbook Exchanges on Ethereum

DEXes on Ethereum have hit their stride. Recent growth has been concentrated in on-chain, curve/ reserve based DEX models. With advances in layer 2 such as zkRollup, the next cycle will see scalable & secure orderbook DEXes take root on Ethereum, allowing for true non-custodial trading, not swapping

Loopring Starts zkSNARK Trusted Setup Multi-Party Computation Ceremony

We will start the phase 2 ceremony on top of the 11th round of phase 1. We will do an additional phase 1 contribution with a random beacon using the Bitcoin block hash at block height 602168 as announced beforehand on Twitter. The resulting data will form the base for Loopring’s phase 2.

Loopring Open Sources its zkSNARK Circuit Code

Loopring has just open-sourced the circuit repository for protocol 3.0: protocol3-circuits. The repository contains 6 circuits. We have set up a 500K LRC bounty program to reward those who identify bugs in our circuits.

LRC Utility in Loopring 3.0

LRC plays a big role in 3.0, and it mostly comes down to staking — staking to reap rewards, secure exchanges, and reduce fees.

Loopring 3.0 Overview: From A to zkSNARKs

This post is meant to provide a quick overview of how Loopring 3.0 works, and how we use zkSNARKs to enable scalable, secure DEXs. For a deep dive, you can check out the full design doc on GitHub.

Loopring Protocol 3.0 Design Doc

We are thrilled to share with you the design of Loopring Protocol 3.0. Our current implementation achieves 450 trades per second without on-chain (Ethereum) data-availability and 80trades per second with on-chain data-availability.

Loopring Protocol 3.0: zkSNARKs for Scalability

Fast, trustless, token trading. Not an oxymoron anymore. It’s with great excitement that today we unveil the design of our newest, fastest, and most forward-looking protocol, Loopring Protocol 3.0.

Oedax: Loopring’s Open-End Dutch Auction Exchange Model

We introduce an enhanced Dutch Auction-based exchange model, Oedax, that allows both buyers and sellers to participate after an auction starts. In this post, we outline the design of such an exchange model and analyze some of its properties.

Loopring’s Uni-Directional Order Model (UDOM)

Loopring Protocol introduced an innovative way of modeling orders, which I called the Unidirectional Order Model, or UDOM for short. As you can notice in our whitepaper, UDOM makes it easier to express order-rings in a clean and concise way.
