Efficient Cross-Chain Transaction Processing on Blockchains

Blockchain has received great attention in academia and industry due to its decentralization immutability. From the perspective of transaction processing, blockchain is a distributed shared ledger database with characteristics decentralization, traceability, transparency. These features ensure security blockchain’s reliability. However, because network requires complex consensus verification between users, it causes problems such as high cost data exchange low system throughput. Such are aggravated when executing cross-chain transaction, particularly important atomicity isolation transactions across blockchain. Considering this, this paper, we propose processing flow EOVPC efficient based on version control. Different from existing approaches locking, optimistic which updated can be used immediately, rolling back procedure that guarantees atomicity. We conducted extensive experiments, show our improve throughput success rate significantly.
