摘　　要：近年来,区块链作为一门新兴技术得到了广泛关注。但是,区块链技术离真正的投入使用还有相当长的一段路程需要走。目前,区块链无法投入生产的一个重要因素,是现存的区块链系统的低吞吐率无法满足现实生产的需要。例如,理论上,比特币是7 TPS,以太坊是15 TPS,而传统的中心化系统如VISA,支持上千的TPS。因此,分析限制区块链扩展性的主要因素,抽离出提高吞吐率的模型,并且针对每个方面进行具体分析,为以后的研究奠定基础。In recent years, blockchain has received extensive attention as an emerging technology. However, blockchain technology still has a long way to go before it is actually put into use. At present, an important factor that the blockchain cannot be put into production is that the low throughput rate of the existing blockchain system cannot meet the needs of real production. For example, in theory, Bitcoin is 7TPS, Ethereum is 15 TPS, and traditional centralized systems such as VISA support thousands of TPS. Therefore, the main factors that limit the scalability of the blockchain are analyzed, and the model for increasing the throughput rate is extracted. And each of the above aspects is specifically analyzed to lay the foundation for future research.
