Abstract: Since dual-middle platform architecture of “data and business” was first proposed, the efficiency of secure data interaction between middle platforms has become particularly important. This paper proposes an efficient interaction protocol, while ensuring data security and credibility with the help of a blockchain dual-chain structure, to optimize the efficiency of endogenous data interaction between middle platforms. By extracting the core threshold signature technology in the new protocol, the simulation experiment showed that the protocol reduced 42.1% of the overhead time used in the off-chain signature and on-chain verification processes compared with the method for traditional single signature and on-chain verification. The new protocol will have a positive impact on the integration of blockchain technology in the middle platform and on accelerating the overall adoption of the middle platform and blockchain.

Key words: dual-middle platform and dual-chain architecture, efficient data exchange protocol, off-chain threshold signature, on-chain verification signature, blockchain
