摘要
现有云制造平台系统中普遍存在信息孤岛、信任度低和用户隐私威胁等问题。区块链是一种由分布式数据存储、P2P传输、共识机制、数字签名和加密算法等计算机技术实现的分布式记账系统,具有去中心化、集体维护性、不易篡改、匿名性和可追溯性等特点,能够有效化解当前难题。为此提出了基于双链架构的云制造平台系统架构模型的构想,设计了一种基于区块链交易的信息记录与查询验真机制,提出了一种云制造平台上利用区块链交易的新思路。
In the existing cloud manufacturing platform systems,the information silosp henomenon,low trust and user privacy threat are common. The blockchain is a distributed accounting system realized by computer technology such as distributed data storage,point-to-point transmission,consensus mechanism,digital signature and encryption algorithm,etc. It is decentralized,collective maintenance,traceable and the information can hardly be tampered with,which can effectively solve the above problems. This paper proposed a architecture model of cloud manufacturing platform system based on double-chain architecture,designed a transfer information record/verification mechanism,and proposed a new way of using blockchain transaction on cloud manufacturing platform.
