摘要： 电子仓单是供应链物流流转过程中的重要凭证，电子仓单及其背后的仓储过程信息必须是可信且不可修改的，而传统数据库技术无法有效解决这一问题.针对仓储物流中物联网的特点，利用区块链技术设计了区块链系统以存储电子仓单及相关物联网信息的总体框架，并设计了基于信誉度的共识算法.基于Bitcoin源码设计了可以存储各种信息以及适合交易运算的底层区块存储系统，并且设计了可以交易电子仓单以及存储仓储信息的交易算法.实验证明了该系统的有效性和可行性.

关键词: 电子仓单, 信誉度, 共识算法, 信息存储, 交易算法

Abstract: Warehouse receipt is an important voucher in the supply-chain logistics circulation. The basic requirement is that the electronic warehouse receipts and its warehouse process information are credible and non-modifiable, but the traditional database technology cannot solve these issues. In this paper, based on blockchain technology, the overall framework for storing electronic warehouse and related IoT information is proposed, and a consensus algorithm-based credit degree is designed. Based on the source code of bitcoin, an underlying blockchain storage system is re-designed to store various information and to be suitable for trading operations. The trading algorithm that can trade warehouse and store storage information is redesigned. Finally, experimental results show the system has good effectiveness and practicability.

Key words: electronic warehouse, credit degree, consensus algorithm, information storage, trading algorithm
