摘　　要：针对区块链以预言机为中介、与链下数据交互效率低这一问题,提出了一个基于Schnorr门限签名的区块链预言机方案.该方案在Schnorr门限签名的基础上结合线性秘密共享算法对多签名进行聚合;同时采用多预言机获取物理世界的数据信息,实现了从预言机到区块链高效、高可靠性的数据传输.分析及实验表明,该方案具备较好的安全性及性能.A blockchain oracle scheme base on Schnorr threshold signatures is proposed to address the inefficiency of blockchain interactions with off-chain data when using oracles as intermediaries.The scheme aggregates multiple signatures based on the Schnorr threshold signature combined with the linear secret sharing algorithm.Additionally,it employs multiple oracles to obtain data information in the physical world,and achieves efficient and highly reliable data transmission from the oracle to the blockchain.The analyses and experiments demonstrate that the scheme offers good security and performance.
