E-commerce blockchain consensus mechanism for supporting high-throughput and real-time transaction

Abstract

Transactions may be altered, which leads to low credibility of transactions that restricts the rapid development and popularization of E-commerce. Although blockchain can ensure high stability and credibility of data, existing solutions still have some significant scalability barriers, such as low-throughput and high-latency. To improve credibility, this paper presents an e-commerce blockchain consensus mechanism (EBCM). EBCM does not rely on computing power and token but with the same level of security and credibility as Nakamoto consensus. Meanwhile, EBCM achieves real-time transaction and high-throughput. By introducing validation blockchain, we can ensure transactions cannot be altered. In order to realize high-throughput and real-time transaction, this paper constructs a two-layer blockchain. EBCM has been compared with Bitcoin in performance, and demonstrates better on throughput, latency.
