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.
Research & Development
We ran some proof-generation benchmarking on AWS. The average cost per settlement turns out to be as low as $0.0021 USD, which is better than we initially expected.
*DA = (On-Chain) Data-Availability
We also ran a similar benchmark using GPUs. Comparing results on Nvidia GTX 1080 GPU and Intel i5–7500, the performance on GPU is twice as good as the performance on CPU. If we can migrate Fast Fourier Transforms to GPU, the performance is likely to be even better.
We have also implemented the Poseidon hash function in Java and EdDSA on the BabyJubjub curve.
We have completed the integration testing for deposit, withdrawal, and settlement requests. We fixed many bugs and verified the logic of each module. We have also re-implemented deployment automation to achieve faster deployment. We are now working on improving the relayer’s overall quality by performing even more testing, adding tracing and monitoring, and enabling one-click deployment.
We have integrated our Web-based DEX application with many Lightcone 2.0’s REST/WebSocket APIs, including those for deposit, withdrawal, and trading. There are more API integration and testing to be done.
