一种基于指纹存证协助的智能合约模型的设计

Design of an intelligent contract model based on fingerprint deposit certificate assistance

区块链技术作为分布式记账技术,为电网中多方交易提供了信任平台。由于数字信息易被复制和篡改,如何安全、可靠存储存证成为亟待解决的问题。为此,提出基于指纹存证协助的智能合约模型。将指纹存证和区块链相结合,充分发挥指纹存证的存证效率高、存储量小的特点。区块链端用于记录电网资产关键数据及其信息变更的HASH值,保证存证信息的真实可信。同时,采用环签名技术,进一步提高了存证信息的安全性。采用Solidate语言设计区块链智能合约模型,提升系统效率。经分析与实验表明,该模型提高了存证信息的安全性和系统吞吐量。

As a distributed accounting technology,blockchain technology provides a trust platform for multi-party transactions in the power grid.Since digital information is easy to be copied and tampered with,how to safely and reliably store the deposit certificate becomes an urgent problem to be solved.Therefore,an intelligent contract model based on fingerprint deposit certificate-assistance is designed in this paper.In the proposed model,the fingerprint deposit certificate and blockchain technology are combined in order to give full play to the characteristics of high storage efficiency and small storage capacity of fingerprint deposit certificate.The blockchain terminal is used to record the HASH value of the key data and information changes of the power grid assets to ensure the authenticity and credibility of the stored information.At the same time,the ring signature technology is adopted in the proposed model to improve the security of the information.The intelligent contract model of block chain is designed with Solidate language to improve system efficiency.The analysis and experiments show that the model improves the security and throughput of the system of the information.
