Description
技术领域
本发明属于金融技术领域,具体涉及一种基于区块链的供应链金融领域。
背景技术
在我国,中小微型企业在国民经济中占有绝对主体地位,对促进就业、发明创造以及GDP的增长发挥着重要的推动作用。但由于自身企业规模的限制,中小微型企业在日常经营过程中,常常会出现融资难题,长久以来,一直是阻碍其健康发展的绊脚石。供应链金融的出现,可以为企业提供资金支持,保障中小微型企业的健康运营。但是由于信息不透明,在提供金融服务的时候,常常会出现融资企业资质不足、动产重复质押、空单质押、物流企业监守自盗等众多问题,极大地影响了供应链金融的发展。
发明内容
本发明为解决中小微型企业融资难和供应链金融存在的信息不透明的问题,提供一种基于区块链的供应链金融架构,降低产业链中任一企业的信用风险,使得总体风险可控。
具体为:
步骤1、与金融机构建立电子合约,约定合约履行条件;
步骤2、采集产业链上下游各个环节的企业信息和贸易信息,并进行代码化处理;
步骤3、对所述信息进行操作处理,利用区块链的去中心化方式分步记录产业链上下游企业的每一笔交易信息,并针对所有交易信息依次建立各区块;
步骤4、通过哈希算法结合公私密钥签名认证方法对每一笔交易信息加盖时间戳;
步骤5、对最后一次区块的函数值进行验证是否满足程序约定的条件,如果满足,自动执行合约的相关交易,如果不满足,则不执行合约的相关交易。
进一步的,步骤2中记录的每一笔交易信息都予以完整的记录且由全金融机构和产业链上下游各个环节的接收。
进一步的,可以糅合产业链交易中的物联网信息,借助物理传感器记录货物的物流、仓储信息,并实施反馈。
附图说明
图1是基于区块链的供应链金融增信方法图,附图标记1为供应商、2为生产商、3为销售商、4为金融机构、5为供应商管理、6为生产商管理、7为销售商管理、8为金融机构管理、9为信息流、10为区块链智能合约平台。
具体实施方式
下面结合说明书附图对本发明做进一步说明:
实施例1
步骤1、与金融机构建立电子合约,约定合约履行条件;
步骤2、采集产业链上下游各个环节的企业信息和贸易信息,并进行代码化处理;
步骤3、对所述信息进行操作处理,利用区块链的去中心化方式分步记录产业链上下游企业的每一笔交易信息,并针对所有交易信息依次建立各区块;
步骤4、通过哈希算法结合公私密钥签名认证方法对每一笔交易信息加盖时间戳;
步骤5、对最后一次区块的函数值进行验证是否满足程序约定的条件,如果满足,自动执行合约的相关交易,如果不满足,则不执行合约的相关交易。
进一步的,步骤2中记录的每一笔交易信息都予以完整的记录且由全金融机构和产业链上下游各个环节的接收。
进一步的,可以糅合产业链交易中的物联网信息,借助物理传感器记录货物的物流、仓储信息,并实施反馈。
以上所述实施例的各技术特征可以进行任意的组合,为使描述简洁,未对上述实施例中的各个技术特征所有可能的组合都进行描述,然而,只要这些技术特征的组合不存在矛盾,都应当认为是本说明书记载的范围。
以上所述实施例仅表达了本发明一些示例性实施例,其描述较为具体和详细,但并不能因此而理解为对本发明专利范围的限制。应当指出的是,对于本领域的普通技术人员来说,在不脱离本发明构思的前提下,还可以做出若干变形和改进,这些都属于本发明的保护范围。因此,本发明专利的保护范围应以所附权利要求为准。
