In view of the problems of high data storage cost, low time efficiency, and inability to prevent malicious oracle nodes from transmitting incorrect data, a blockchain oracle data transmission model based on threshold aggregation signature was proposed. Firstly, the signature and data were aggregated on an oracle, and a single interaction with the smart contract on the chain reduced the blockchain storage space overhead and communication load. Secondly, a threshold mechanism was added to the Schnorr aggregate signature to improve the efficiency of signature time. Finally, multiple oracles were used to collect data, and a point system was set up to elect a credible signature aggregation oracle to prevent the behavior of some malicious oracles and ensure the reliability of the data. The experimental results showed that the Schnorr threshold aggregation signature consumed less time than the BLS aggregation signature and the Schnorr aggregation signature without threshold mechanism, which enabled users to obtain off-chain data and transmit it more quickly.
