Blockchain is the perfect medium for constant storage, information recording and command execution. However, on-chain networks cannot interact with trusted information spontaneously without assistance from external nodes. An oracle is just working as the decentralized bridge between blockchain and trusted information， allowing smart contracts to give response to external environment with no boundaries.Learn more
The current oracle solutions in the market can be divided into two types. One is to collect data off chain and conduct the validation on chain. The common drawbacks of these oracles include low efficiency, poor timeliness and high gas fee, so they can only operate properly but with restrictions when related assets are not time sensitive. Another type is to collect data that have been generated on chain, but it suffers seriously when the market shows continuous one-directional trend like now.Learn more
We designed our foundational architecture based on current cross-chain networks, which has introduced and modified based on the quoting system used by global top organizations in high-frequency automatic trading for single benchmark in multiple trading scenarios. Pledged asset quoting and arbitrage validation are used to build real-time quoting validation mechanism. In extreme situations, a price curve can be generated more smoothly by statistical hypothesis-testing, which has higher practical value for Dapps compared with existing oracle solutions.Learn more
The quoting efficiency of Paul Oracle is 5-10 times of that of existing oracles in the market, which can respond to the market change with the fastest speed.
Compared with the expensive network fee of smart contracts on Ethereum network, the cost on Paul Oracle is controlled to the minimum level.
Driven by both valid quote and hypothesis-testing effective deal quote mechanism. The double-mechanism design ensures its quoting stability under extreme situations.
We are working on supporting all high-performance public chains including BSC, HECO, SOL, etc. Final step is to integrate cross-chain protocol and launch cross-chain quoting.
