标题： Maximizing Blockchain Performance: Mitigating Conflicting Transactions through Parallelism and Dependency Management

摘要： 尽管区块链最初在加密货币领域获得了关注，但随着增强数据安全的需求日益迫切，其广泛应用正在超越传统的应用场景。 尽管区块链提供了一个安全的网络环境，但它也伴随着一些权衡问题，包括高延迟、低吞吐量以及交易失败率的增加。 导致这些挑战的一个关键问题是“冲突交易”的管理不当，通常被称为“竞争”。 当区块链中的多个待处理交易相互冲突时，就会产生竞争状态。 这种情况会加剧网络延迟，浪费系统资源，并最终导致吞吐量下降和交易失败率上升。 为了解决这一问题，本文提出了一种新的区块链方案，该方案结合了交易并行性和智能依赖管理器，旨在减少区块链网络中冲突交易的发生。 在有效性和效率方面，实验结果显示，我们的方案不仅缓解了冲突交易带来的挑战，而且在交易成功率、吞吐量和延迟方面均优于现有的并行和非并行 Hyperledger Fabric 区块链网络。 将我们的方案与 Hyperledger Fabric 集成似乎是在实际应用中提升区块链网络整体性能和稳定性的有前景的解决方案。 显示英文摘要

摘要： While blockchains initially gained popularity in the realm of cryptocurrencies, their widespread adoption is expanding beyond conventional applications, driven by the imperative need for enhanced data security. Despite providing a secure network, blockchains come with certain tradeoffs, including high latency, lower throughput, and an increased number of transaction failures. A pivotal issue contributing to these challenges is the improper management of "conflicting transactions", commonly referred to as "contention". When a number of pending transactions within a blockchain collide with each other, this results in a state of contention. This situation worsens network latency, leads to the wastage of system resources, and ultimately contributes to reduced throughput and higher transaction failures. In response to this issue, in this work, we present a novel blockchain scheme that integrates transaction parallelism and an intelligent dependency manager aiming to reduce the occurrence of conflicting transactions within blockchain networks. In terms of effectiveness and efficiency, experimental results show that our scheme not only mitigates the challenges posed by conflicting transactions, but also outperforms both existing parallel and non-parallel Hyperledger Fabric blockchain networks achieving higher transaction success rate, throughput, and latency. The integration of our scheme with Hyperledger Fabric appears to be a promising solution for improving the overall performance and stability of blockchain networks in real-world applications.
