本申请由交易所、第三方权威机构、保险公司及监管方的节点搭建区块链网络，所有信息记录在区块链上，用户在交易所节点提供的信用系统应用中发起交易请求，通过第三方权威机构基于用户信息对用户进行信用评价后，用户可以在交易所发起携带贷款类型及需求信息的借款请求，保险公司评估是否承保，在保险公司确认承保且风控审核通过后，交易所形成正式合约，通过信用系统应用发布正式合约，供资方查阅，如果资方确定投资，则根据该正式合约及资方的投资信息生成相应的贷款合同，贷款合同生效后，用户可在交易所提现贷款款额，本申请构建信贷借款的区块链网络，提供一种安全、可信度高的信贷借款方法，简化贷款操作、缩短整体的贷款时效并节约用户的贷款成本。
本申请还提供一种基于区块链的借贷运行方法，如图3所示，图3为本申请基于区块链的借贷运行方法一实施例的流程示意图，该基于区块链的借贷运行方法包括以下步骤：
步骤S1，在预先搭建的区块链网络中，交易所节点的信用系统应用接收携带用户信息及授权信息的交易请求，通过智能合约将该用户信息及授权信息记录在区块链账本中；
其中，用户在交易所节点的信用系统应用中注册，向交易所节点发起交易请求，提交用户信息及授权信息，用户信息包括个人基本信息、个人需要背书的信用资产信息，授权信息为交易所节点与区块链中的其他节点两两之间是否授权使用数据的信息。
在本申请的所有实施例中，非隐私信息(例如，授权信息)采用密文上传；隐私信息(例如，用户信息)采用利用私钥加密后记录进区块链账本中。
步骤S2，第三方权威机构节点基于该用户信息对用户进行信用评价， 通过智能合约将进行信用评价后的信用评分记录在该区块链账本中；
第三方权威机构节点从区块链账本中得到用户信息，根据用户信息进行用户征信评价，并提供一个基础版信用评分，该信用评分决定用户的初始身价，第三方权威机构节点发起交易，通过智能合约将用户的信用评分上链，记录在区块链账本中，所有节点可以得到该数据。
在一实施例中，为了提高可信度，第三方权威机构节点基于该用户信息对用户进行信用评价的步骤包括：
对用户进行身份验证：获取公安部门中与该用户信息中的身份证号码相同的用户的待验证信息，将该用户信息与该待验证信息进行匹配，以进行身份验证；若身份验证通过，则查询该用户的个人征信纪录，根据该个人征信纪录生成所述信用评分。
其中，将该用户信息与该待验证信息进行匹配时，应将身份证号码、姓名、性别、家庭情况、个人职业信息等进行一一匹配，以及将用户的生理特征信息进行匹配，例如，使用人脸识别技术，通过获取用户当前的人脸图片，并在公安部下载用户的存档图片，两者进行二维人脸识别，以进行身份认证。
其中，在根据该个人征信纪录生成所述信用评分之后，由其他的三方机构对用户的信用资产进行背书。例如，房交所确认用户的房产信息真实有效，且未进行抵押，并返回结果给第三方权威机构节点；又如，若用户为学生，则教育部会对学生所在的学校以及学籍信息进行背书，并返回结果给第三方权威机构节点。
步骤S3，所述信用系统应用接收用户发起的携带贷款类型及需求信息的借款请求，若该用户的信用评分大于等于预定的信用评分，则通过智能合约将该贷款类型及需求信息记录在该区块链账本中，并将该贷款类型及需求信息推送至保险公司节点；
其中，贷款类型包括非公益性贷款及公益性贷款。非公益性贷款需要还 款，公益性贷款不需要还款。
其中，信用评分必须满足设定要求才能发起借款请求，具体的程度由交易所的风控部以及信用审核部决定。本实施例中信用评分大于等于预定的信用评分才能发起借款请求。最大贷款金额只有在信用评价之后才能被认可。在交易所挂交易的时候，不允许超出最大贷款金额。
本实施例中，若该用户的信用评分大于等于预定的信用评分，则交易所节点基于预定的信用评分与最大贷款金额的关联关系，确定该用户的信用评分对应的最大贷款金额，通过智能合约将该最大贷款金额记录在该区块链账本中。
其中，用户在信用系统应用发起借款请求，可承诺在一定的时限内，付出一定的代价(利息)，利用信用资产换取额度内的款额，该借款需求实际上对应了各种以信用评价为标准将自身打包的产品。
对于非公益性贷款，需求信息例如为：企业主A，我在天府广场有一套房(房交所背书认证)，因资金周转情况，寻求一笔20万的资金，为期1年，提供年华利率8％。
对于公益性贷款，需求信息例如为：学生B，我是一个在校大学生(教育部背书认证)，因为家庭情况比较困难，寻求一笔5000的资金缴学费，为期1年，无法提供利息。
步骤S4，所述保险公司节点在分析该贷款类型及需求信息后，若确认承保，则基于该用户信息、信用评分及需求信息形成基础合约，以由风控对该基础合约进行审核，并在审核通过后，通过智能合约将该基础合约及审核通过的信息记录至该区块链账本中；
其中，交易所节点将数据写入区块链后，保险公司节点会定时扫描区块链获取新区块中的贷款类型及需求信息。在确定承保后，形成基础合约，风控基础合约进行审核，审核通过后该基础合约及审核通过的信息记录在区块 链中。
步骤S5，所述交易所节点基于该基础合约及审核通过的信息形成正式合约，在所述信用系统应用中发布该正式合约，供资方查阅，并通过所述信用系统应用接收资方的投资信息，根据该正式合约及资方的投资信息生成相应的贷款合同，通过智能合约将该贷款合同记录在所述区块链账本上；
其中，由交易所节点基于基础合约及审核通过的信息形成正式合约，该正式合约在所述信用系统应用中发布，资方在交易所节点的信用系统应用中查看或接收正式合约，给出借贷结果。若资方同意投资，则资方在信用系统应用中输入投资信息，该投资信息包括投资人基本信息、是否投资的信息。然后，根据正式合约及资方的投资信息生成相应的贷款合同，贷款合同包括了用户信息、第三方权威机构、资方的投资信息、担保方、借款利率、投资利率及其他服务明细等。
在一实施例中，为了对整个信用贷款的的过程进行监管，还包括：监管方节点发起查看所述贷款合同的交易请求，以对基于所述贷款合同的贷款过程进行监管，防止有不法的贷款交易出现。
步骤S6，若该用户在交易所提现基于该贷款合同的款额，则交易所节点将该用户提现款额的提现信息通过智能合约记录在所述区块链账本上。
其中，贷款合同生效后，资方通过个人钱包充值，将充值后的资金通过交易所报盘到资金池。用户通过交易所提现贷款合同的款额，这些信息都记录在区块链中。同时区块链还可以赋予用户和资方挖矿资格，并可在资金使用过程中，用户和资方可根据时间、资金等因素以挖矿的形式产生积分奖励。
在一实施例中，在上述实施例的基础上，若所述贷款类型为非公益性贷款，如图4所示，则所述步骤S6之后，还包括：步骤S107，所述交易所节点的信用系统应用在接收用户发起的按时还款请求后，获取还款信息，若该还款信息与所述贷款合同中记录的还款约定信息一致，则通过智能合约将本 次还款信息记录在所述区块链账本上。
其中，用户履行贷款合同，在还款日在交易所节点的信用系统应用中发起还款交易请求，交易所节点接收到请求后，用户根据贷款合同并通过交易所还款，用户将资金充值到个人钱包，由交易所定时到用户的个人钱包里面进行划扣，将资金划扣至资方的个人钱包。当用户的所有款项还完后，交易所产生交易记录、履约记录、合同完成记录，信息记录至区块链。其中，该记录包括：还款计划、还款记录、资金分配明细。
在另一实施例中，在上述实施例的基础上，若所述贷款类型为非公益性贷款，如图5所示，则所述步骤S6之后，还包括：步骤S207，所述交易所节点的信用系统应用在接收用户发起的提前还款请求后，获取还款信息，若该还款信息与所述贷款合同中记录的还款约定信息一致，则生成补充协议，则通过智能合约将本次还款信息及该补充协议记录在所述区块链账本上。
本实施例与上一实施例不同的是，用户进行了提前还款，提高应用灵活性。交易所节点接收到请求后，在原有贷款合同的基础上，生成补充协议。其中，补充协议包括：提前还款的金额、日期、对还款计划的修正。当用户的所有款项还完后，交易所产生交易记录、履约记录、合同完成记录，信息记录至区块链。其中，该记录包括：还款计划、还款记录、资金分配明细。
在一实施例中，所述步骤S6之后，还包括：若该用户在交易所提现基于该贷款合同的款额，则所述交易所节点基于所提现的款额降低所述最大贷款金额，通过智能合约将降低后的最大贷款金额记录在该区块链账本中；
在该用户还款完成后，所述交易所节点恢复该用户的最大贷款金额，并根据所述正式合约及本次还款信息提高该用户的最大贷款金额，通过智能合约将提高后的最大贷款金额记录在该区块链账本中。
进一步地，用户及资方都可以通过资产证明自身的信用价值的提升，例如资方投资的总额为多少，对应的信用价值提升了多少；借款方借款的总额 度是多少，对应的信用价值提升了多少。对于借款方来说，如果信用价值提升了，那么最大贷款金额相应也提高了。
