Driven in part of the rapid growth of consortium blockchain applications, blockchain interoperability becomes extremely essential to exchange transactional data among decentralized applications. To ensure the data integrity of transactions, the state-of-the-art studies of the blockchain interoperability apply data locks, which however severely decrease system efficiency. To boost interoperability performance, this paper proposes a novel approach based on multi-version concurrency control to parallelize interoperable transactions, which aims high transaction processing throughput while ensuring data integrity. The experimental evaluation with the Smallbank benchmark shows that the proposed method achieves up to 4x performance increase (in terms of processed transactions per second, TPS) compared with the existing methods, and moreover, it decreases the average latency with 58%.
