In digital asset trading, blockchain oracles play a crucial role. This paper proposes a novel oracle price feed framework to address the significant price deviations and high maintenance costs associated with oracles in digital asset trading. This framework employs off-chain data to cleanse on-chain exchange price information, effectively preventing abnormal price deviations of assets. Simultaneously, by increasing the deviation threshold for passive price feeds, the frequency of passive feeds is reduced, lowering the cost of uploading off-chain data to the blockchain and thereby decreasing the maintenance costs of the oracle.

摘要

In digital asset trading, blockchain oracles play a crucial role. This paper proposes a novel oracle price feed framework to address the significant price deviations and high maintenance costs associated with oracles in digital asset trading. This framework employs off-chain data to cleanse on-chain exchange price information, effectively preventing abnormal price deviations of assets. Simultaneously, by increasing the deviation threshold for passive price feeds, the frequency of passive feeds is reduced, lowering the cost of uploading off-chain data to the blockchain and thereby decreasing the maintenance costs of the oracle.
