ShuttleCross: an Efficient Cross-Chain Smart Contract Invocation Framework

Cross-chain smart contract invocation enables interoperability among different blockchain service platforms. With the growing demand for cross-chain services, the performance of cross-chain smart contract invocations is becoming increasingly important. However, current cross-chain smart contract invocation technologies suffer from long latency and high abort rates. In this paper, we present ShuttleCross, an efficient cross-chain smart contract invocation framework, which ensures the atomicity and serializability of cross-chain transactions. ShuttleCross employs a hybrid concurrency control protocol to reduce the high abort rates caused by read-write conflicts of concurrent cross-chain transactions. Furthermore, ShuttleCross adopts a read-write separation strategy to accelerate cross-chain transaction execution by executing read-only function invocations off-chain. Our experimental results demonstrate that ShuttleCross significantly improves the performance of cross-chain transaction execution.
