| 摘 要： | 传统的基于主/从的数据处理框架容易受到主节点的单点故障和性能瓶颈的影响。相比之下, 区块链系统采用去中心化的框架, 能够聚合海量的计算资源。提出了一种基于区块链的数据处理框架, 利用区块链的优点来解决中心化框架的缺点。在所提出的框架中, 区块链存储任务信息, 采用的有用工作共识证明共识机制使节点能够使用其计算资源处理任务, 同时竞争领导者(将待处理的任务分派到区块链)。模拟表明, 所提出的框架在吞吐量和任务响应时间方面优于集中式框架。

| Abstract: | Conventional master/slave-based data processing frameworks are vulnerable to single point of failure and performance bottlenecks of the master node. In contrast, blockchain systems adopt a decentralized framework and are capable of aggregating enormous computing resources. A blockchain-based data processing framework is proposed that utilizes the advantages of the blockchain for solving the drawbacks of the centralized framework. In this framework, the blockchain stores the task information and the adopted proof of useful work consensus enables nodes to process tasks using their computing resources, while competing for the leader (who dispatches pending tasks to the blockchain). Extensive simulations show that the proposed framework is better than the centralized framework in terms of the throughput and the task response time. |
