Abstract

Blockchain has penetrated in various fields, such as finance, healthcare, supply chain, and intelligent transportation, but the value exchange between different blockchains limits their expansion. Cross-chain technology, such as notary mechanism, enables asset exchanges between different blockchain networks. However, existing research still confronts problems such as single inherent value evaluation, collusion risk, credit evaluation and unreasonable resource allocation, making it difficult to ensure the security of cross-chain asset transactions. So this paper proposes a cross-chain asset trading scheme based on edge cloud storage to improve the reliability of notaries and the security of cross-chain value exchange. Firstly, introduce the entropy weight method to determine indicators and adopt multi indicator evaluation to reduce the risk of collusion between notaries and users; Secondly, design a multi-indicator credit evaluation method to improve the accuracy of the evaluation; Finally, design a new and old notary node share allocation method to improve the rationality of resource allocation.The experiment shows that the scheme designed in this paper can reduce the risk of collusion, more accurately screen out high credit nodes to act as notaries, and make resource allocation more reasonable.
基于边缘云存储的公证人跨链资产交易方案
区块链已渗透到金融、医疗、供应链、智能交通等各个领域,但不同区块链之间的价值交换限制了其扩展。公证机制等跨链技术实现了不同区块链网络之间的资产交换。但现有研究仍面临单一固有价值评估、串通风险、信用评估、资源分配不合理等问题,难以保证跨链资产交易的安全性。因此,本文提出了一种基于边缘云存储的跨链资产交易方案,以提高公证的可靠性和跨链价值交换的安全性。首先,引入熵权法确定指标,采用多指标评价,降低公证员与用户之间的串通风险;其次,设计多指标信用评价方法,提高评价的准确性;最后,设计新旧公证节点份额分配方法,提高资源分配的合理性。实验表明,本文设计的方案可以降低串通风险,更准确地筛选出高信用节点担任公证员,使资源分配更加合理。
