  • The team behind Open finance protocol Synthetix joined up with Ethereum layer-2 research group Optimism for a demo built on the Optimistic Virtual Machine (OVM)
  • OVM is the virtual machine for the Optimistic Rollup, an Ethereum Layer-2 scaling solution
  • The demo demonstrated how the new setup can reduce oracle update latency by 37.5 times and exchange latency by 75 times

Open finance protocol Synthetix and research group Optimism have teamed up to launch a new demo for Optimistic Rollup, taking another step towards developing a full-fledged Ethereum Layer-2 scaling solution.

The two-week demo utilizes Optimistic Virtual Machine (OVM) – the virtual machine that Optimism built for its Optimistic Rollup solution – to test the smart contract scalability of the layer-2 solution. However, deposit and withdrawal from Ethereum mainchain to the OVM on layer 2 is not available at this time.

As previously reported by The Block, Optimism's OVM is integrated with the same tooling and smart contract languages as those used on the Ethereum mainnet, allowing developers to deploy smart contracts on the Layer-2 solution as they appear on Layer 1. This feature is very attractive to Synthetix, as OVM can transfer all of the protocol's smart contracts from Layer 1 to Layer 2 without requiring any change, Synthetix CTO Justin J Moses told The Block.

"On L2, Synthetix can update its price oracle more frequently, which means they do not have to temporarily halt transactions like they do on L1. We've found cheap oracle updates to be an unexpectedly major benefit of L2 for DeFi," Optimism CEO Jinglan Wang told The Block.

Synthetix is the second-largest Open Finance protocol by total locked value, per DeFi Pulse. Optimism, on the other hand, recently received a $3.5 million seed round from Paradigm and IDEO CoLab Ventures, after it successfully showcased the feasibility of Optimistic Rollup in a demo last October in collaboration with decentralized exchange Uniswap.

However, different from the October demo that required custom codes, the Synthetix demo did not need any special code and can be generally deployed with other DeFi protocols.

“We did have to do a lot of debugging but there’s nothing special we built for Synthetix," said Wang.

According to Optimism, the Synthetix demo could achieve a 37.5 times reduction in oracle update latency and a 75 times reduction in transaction delay, compared to the 15 second average transaction time on the Ethereum mainnet. It also demonstrates how oracle-and exchange-related gas prices can be reduced by 27.2 times and 143 times, respectively.

As part of the demo, the two startups also launched a trading competition to stress test the OVM. Traders generating the highest returns will be rewarded up to 15,000 SNX, worth around $11,442.

Next, the Optimism team plans to combine the OVM full node from the Optimistic Rollup demo with the backend from Unipig, in order to deploy "a fully Ethereum compatible Layer 2 protocol," an Optimism blog post stated.

Synthetix, meanwhile, plans to be live on Optimism's Layer 2 solution once it is deployed on the Ethereum mainnet, according to founder Kain Warwick.
