Since July 2020, as different DEX such as Uniswap and Sushiswap developed increasingly fast, together with the prosperity of the overall supporting ecosystem, DeFi has quickly become the absolute trending topic in the investment market. All financial products are trying their best to look for their decentralized alternative solutions. Under this background, the on-chain derivatives trading has become an inevitable trend. However, restricted by the low efficiency, poor timeliness and high gas of existing oracle solutions in the market, derivatives trading can only be carried out with strict limitations currently. The market demand for blockchain oracles that have higher performance and stronger stability is increasing exponentially and has never been as high as today. Therefore, we decide to design and develop a new oracle protocol that has strong usability, high performance and supports cross-chain interactions, so that it can provide organic soil to the DeFi industry which supports upgraded complexity and diversity of Dapps.
