附图说明
为了更清楚地说明本发明实施例中的技术方案,下面将对实施例中所需要使用的附图作简单地介绍,显而易见地,下面描述中的附图仅仅是本发明的一些实施例,对于本领域普通技术人员来讲,在不付出创造性劳动性的前提下,还可以根据这些附图获得其他的附图。

具体实施方式
在对贷款产品的控制和管理研究中发现,不同的贷款产品对贷款流程的要求不同,比如A产品对应的贷款流程是先进行风控审核,审核通过之后进行网签,B产品对应的贷款流程则是先进行网签,网签成功之后再进行风控审核。 如此情况下,需要针对不同的贷款产品进行单独的产品开发,这样一来极大的增加了开发成本,降低了开发效率。为了解决这一问题,本申请实施例提出了一种基于区块链的信息处理方法、装置以及区块链网络,区块链在接收到终端发送的针对目标交易产品的交易请求时,对该交易请求进行验证。若验证通过了,区块链获取用户的区块链账户中的用户信息,并获取目标交易产品的产品标识对应的智能合约,然后根据用户信息和智能合约生成交易合同,并更新交易合同包括的交易流程的执行状态,实现了针对不同交易产品,根据智能合约生成并更新交易合同,降低了开发成本,提高了交易处理的效率。
下面将结合本发明实施例中的附图,对本发明实施例中的技术方案进行清楚、完整地描述,显然,所描述的实施例是本发明一部分实施例,而不是全部的实施例。基于本发明中的实施例,本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例,都属于本发明保护的范围。
参见图1,为本发明实施例提供的一种基于区块链的信息处理方法应用的系统架构图。如图1所示的基于区块链的信息处理系统可包括终端10、区块链20和支撑服务器30,需要说明的是该交易处理系统可以应用在贷款领域以实现贷款控制,也可以应用在如物流、公司之间业务处理流程等方面。其中,终端10可以是手机、平板电脑、以及笔记本电脑等便携式设备,或者也可以是台式电脑等非便携式设备。区块链20中可包括多个节点,多个节点之间相互协作实现基于区块链的信息处理;支撑服务器30可以包括多个不同类型的支撑服务器,可用于执行不同的交易流程比如风控审核支撑服务器、网签审核支撑服务器等。
如果一个用户40想要通过上述的基于区块链的信息处理系统进行一笔交易,比如贷款交易,首先用户40可针对目标交易产品向终端10输入操作指令。需要说明的是,目标交易产品可以是终端提供给用户选择的多个交易产品中任意一个,该操作指令用于提示终端10根据该操作指令生成交易请求,并将该交易请求发送给区块链20。可选的,用户40输入的操作指令可以是在终端10预设区域的触摸操作指令、滑动操作指令、按压操作指令等,比如终端10提供一个交易产品选择界面,该交易产品选择界面中包括至少一种交易产品,用户可以通过在终端中点击目标交易产品所在区域即可实现向终端10输入操作 指令。或者,用户40输入的操作指令也可以是针对终端10的预设区域输入的语音指令。需要说明的是,用户40针对交易产品输入操作指令的方式可以是终端10提供一个产品选择界面,该界面中包括至少一种交易产品,然后用户40从多个交易产品中确定一个想要进行交易的目标交易产品,接着点击该目标交易产品所在区域或者按压该交易产品所在区域。
可选的,用户40在针对目标交易产品向终端10输入操作指令之前,用户40可在基于区块链的信息处理系统中进行注册;然后用户40在终端10上登录注册账号即可向终端10输入操作指令。可选的,用户40在交易系统中注册包括:用户40首先向终端10发送注册请求,该注册请求中包括用户信息;终端10接收到注册请求之后,将该注册请求发送给区块链20;区块链20可根据注册请求中包括的用户信息对注册请求进行验证;若验证通过,区块链20则为该用户在区块链20中创建用户的区块链账户。其中,用户40可以是个人也可以是企业。如果用户40为个人时,用户40向终端发送的注册请求中包括的用户个人信息可以为个人的姓名信息和身份信息,区块链20对注册请求进行验证可以是对个人的身份进行验证;如果用户40是企业时,注册请求中包括的用户信息可以是企业纳税人识别号、企业法人等,区块链20对注册请求进行验证可以是对企业的法人以及纳税识别号进行验证。
终端10接收到用户40输入的操作指令之后,可根据该操作指令生成交易请求,该交易请求中可包括用户的区块链账户的签名信息和交易产品对应的产品标识。可选的,交易信息中包括的交易产品对应的产品标识可以是终端10根据用户的操作指令获取到的,比如用户的操纵指令为点击选择交易产品A,则终端可获取到交易产品A对应的产品标识。可选的,交易信息中包括的用户的区块链账户的签名信息的生成方式可以为:终端10接收到用户40的操作指令之后,获取输入该操作指令的用户的区块链账户,然后可利用哈希函数处理该区块链账户,得到区块链账户的摘要信息;进一步的,终端10使用区块链账户的私钥对该摘要信息进行签名,最后得到用户的区块链账户的签名信息。
综上可知当用户40想要通过终端10输入针对目标交易产品的操作指令时,首先用户40需要在终端10中进行登录,可选的,用户40可以使用用户 40的区块链账户在终端10中进行登录,或者可以使用与该区块链账户相关联的账号进行登录。在一种可行的实施方式中,用户40的区块链账户可以是用户40在向终端10针对目标交易产品输入操作指令之前,区块链20根据用户40的注册请求为其创建的。在另一种可行的实施方式中,用户40的区块链账户也可以是用户40通过终端10输入了针对目标交易产品的操作指令后,区块链20根据用户40的操作指令为用户40创建的。然后,终端10可根据用户40的登录信息获取到用户的区块链账户;终端10在获取到区块链账户之后,可以为区块链账户生成区块链账户的签名信息。进而,终端10根据目标交易产品的产品标识和用户的区块链账户的签名信息生成交易请求,并将该交请求发送至区块链20,以便于区块链20可以根据该交易请求生成交易合同。
区块链20接收到终端10发送的交易请求之后,首先可对该交易请求进行验证;如果验证通过,则获取用户的区块链账户中包括的用户信息。可选的,区块链20可以根据交易请求中包括的用户的区块链账户的签名信息对该交易请求进行验证,一种可行的验证方式可以为:区块链20从本地数据库中查找到与交易请求中包括的用户区块链账户的签名信息相关的区块链账户,并获取该区块链账户的公钥;然后利用区块链账户的公钥对区块链账户的签名信息进行解密,得到区块链账户的摘要信息;接着,区块链20对在本地数据库中获取到区块链账户进行哈希运算,得到一个摘要信息;将两次得到的摘要信息进行比较:如果两次得到的摘要信息相同,说明该交易请求是由上述用户40发送的,并且未经过篡改。可以理解的,区块链20通过对交易请求中包括的用户的区块链账户的签名信息进行验证,保证了该交易请求的真实性和合法性。
区块链20对交易请求验证通过,获取到用户的区块链账户中的用户信息之后,可以根据交易请求中包括的产品标识,获取交易产品对应的智能合约。在一种可行的实施方式中,区块链20可根据产品标识获取到交易产品对应的智能合约的账户地址,然后在该账户地址中获取到目标交易产品对应的智能合约。在一种可行的实施方式中,区块链20也可以先根据交易请求中的产品标识获取智能合约,然后再对交易请求进行验证。
区块链20根据上述得到的智能合约和用户信息生成针对目标交易产品的交易合同,并更新交易合同包括的交易流程的执行状态。在一种可行的实施方 式中,智能合约中包括交易产品的交易流程、产品标识、还款方式以及费率中的一种或多种。可选的,区块链20根据用户信息和智能合约生成交易合同,包括:根据交易流程、产品标识、还款方式以及费率中一种或者多种以及用户信息生成交易合同。
在一种可行的实施方式中,区块链20更新交易合同包括的交易流程的执行状态,包括:获取交易合同中当前进行到的目标交易流程的执行状态;在该执行状态为未执行的情况下,向目标交易流程对应的支撑服务器30发送执行请求;接收支撑服务器30响应于该执行请求发送的针对目标交易流程的执行结果;根据执行结果更新交易合同中目标交易流程的执行状态。也就是说,区块链20检测当前交易合同中正在进行的流程的执行状态;如果执行状态为已执行,则可忽略该交易流程,继续检测交易合同中包括的下一个交易流程;如果执行状态为未执行,则向当前交易流程对应的支撑服务器30发送执行请求,以使得支撑服务器30开始执行该交易流程,最后根据执行结果更新交易合同中该交易流程的执行状态。
可选的,上述支撑服务器30的对目标交易流程的执行结果可以有两种:一种是支撑服务器30执行目标交易请求之后确定目标交易流程的执行结果为符合预设执行状态更新条件;另一种是支撑服务器30确定目标交易流程的执行结果为不符合预设执行状态更新条件。在一种可行的实施方式中,区块链20根据执行结果更新交易合同中包括的交易流程的执行状态,包括:若执行结果符合预设执行状态更新条件,则将交易合同中目标交易流程的执行状态由正在处理更新为已完成。在另一种可行的实施方式中,若执行结果为不符合预设执行状态更新条件,则生成目标交易流程执行失败的提示消息。
综上的基于区块链的信息处理方法应用的系统中区块链20对接收到的交易请求进行验证,在验证通过的情况下获取交易请求中包括的用户的区块链账户中的用户信息,然后根据交易请求中包括的产品标识获取交易产品对应的智能合约;进一步的,根据用户信息和智能合约生成了交易合同,并实时监测并交易合同中交易流程的执行状态,实现了根据不同的交易产品的智能合约生成并更新针对交易产品的交易合同,降低了开发成本,提高了交易处理的效率。
参见图2,是本发明实施例提供的一种基于区块链的信息处理方法的示意 流程图,如图2所示的基于区块链的信息处理方法可包括:
S201、区块链接收终端发送的针对目标交易产品的交易请求。
其中,交易请求中可包括用户的区块链账户的签名信息和目标交易产品的产品标识,目标交易产品可指终端提供的供用户选择的所有交易产品中的任意一个。可选的,终端在向区块链发送针对目标交易产品的交易请求之前,包括:终端接收到用户针对目标交易产品输入的操作指令,比如用户的点击操作、按压操作或者滑动操作等;然后根据上述操作指令,终端获取到用户的区块链账户信息和目标交易产品的产品标识;终端可以对用户的区块链账户进行哈希运算,然后通过区块链账户的私钥对其进行签名,生成区块链账户的签名信息;终端将区块链账户的签名信息和目标交易产品的产品标识一同包括在交易请求中发送给区块链。可选的,目标交易产品的产品标识可以是在开发产品阶段确定好的。
在一种可行的实施方式中向终端输入操作指令的用户可以是个人,也可以是非个人,非个人包括企业和渠道方,渠道方可以理解为个人用户可以用来间接申请交易的企业,比如消费者在营业厅购买手机,营业厅可以在取得消费者同意的情况下向区块链申请贷款交易,那么营业厅就可以理解为渠道方。同样的,超市、商场以及其他在区块链中注册的企业都可以理解为渠道方。在一种可行的实施方式中,如果用户是个人和企业,终端根据用户的输入操作指令生成的交易请求中可包括用户的区块链账户的签名信息和产品标识;如果用户是渠道方,终端根据用户输入的操作指令生成的交易请求中除了包括用户的区块链账户的签名信号和产品标识之外,还可包括消费者个人信息和采购信息。
S202、区块链对交易请求进行验证,若验证通过则获取用户的区块链账户中的用户信息。
可以理解,区块链对交易请求验证是为了验证该交易请求的真实性和合法性,也即验证发起该交易请求的用户是否为合法用户,以及该用户的区块链账户是否被篡改过。可选的,区块链对交易请求验证可以是根据交易请求中包括的用户的区块链账户的签名信息对交易请求进行验证:如果对区块链账户的签名信息验证通过,则表明该交易请求是真实的合法的。区块链接收到终端发送的交易请求中包括的区块链账户的签名信息可以是终端利用哈希函数对区块 链账户进行哈希运算得到区块链账户的摘要信息之后,再利用区块链账户的私钥对得到的摘要信息进行签名得到的。
区块链对区块链账户的签名信息进行验证的过程可以是:区块链可根据区块链账户的签名信息在区块链中找到用户的区块链账户并可获取到区块链账户的公钥;利用区块链账户的公钥可解密区块链账户的签名信息,得到解密后的区块链账户的摘要信息;然后区块链可将从数据库找到的用户的区块链账户进行哈希运算,得到运算的区块链账户的摘要信息;区块链将运算得到的区块链账户的摘要信息与解密后的区块链账户的摘要信息对比,如果两者完全一样,则确定交易请求验证通过。
S203、区块链根据产品标识,获取目标交易产品对应的智能合约。
可选的,区块链根据产品标识获取目标交易产品对应的智能合约可行的方式可以是:区块链在区块链中找到与产品标识对应的智能合约的账户地址,然后获取该智能合约的账户地址中的智能合约。在一种可行的实施方式中,产品开发初期,区块链可以根据不同的产品需求文档创建不同的交易产品,如此得到的各个交易产品中包括了与该交易产品对应的需求以及产品标识;区块链可再根据每个交易产品中包括的需求为每个交易产品生成智能合约;然后区块链可以为每个智能合约创建一个智能合约的账户地址,并将该账户地址存储在区块链的各个节点中。可以理解,通过此种创建智能合约账户地址的方法可以使得区块链只要知道产品标识就可以快速准确的从区块链中找到相应的智能合约。
S204、区块链根据用户信息和智能合约生成交易合同,并更新交易合同包括的交易流程的执行状态。
在一种可行的实施方式中,终端发送到区块链的交易请求是由于用户对终端输入了操作指令发起的,该用户可以指个人用户也可以企业和渠道方。如果用户是个人用户,则用户信息可以包括个人的身份信息、姓名以及其他基本信息;如果用户是企业和渠道方,用户信息可以包括企业的纳税人识别号以及企业法人等。
可选的,智能合约中可包括交易产品的交易流程、产品标识、还款方式以及费率中的一种或多种,其中,费率可包括利率、手续费率以及违约率中的一 种或多种。在一种可行的实施方式中,区块链根据用户信息和智能合约生成交易合同,可包括:区块链根据交易流程、产品标识、还款方式以及费率中的一种或多种以及用户信息生成交易合同。
在一种可行的实施方式中,区块链在接收终端发送针对目标交易产品的交易请求之前,基于区块链的信息处理方法还包括:区块链接收用户的注册请求,注册请求中包括用户的用户信息;若用户对注册请求验证通过,则区块链为用户创建区块链账户。在另一种可行的实施方式中,区块链为用户创建用户的区块链账户的方式也可以是当终端接收到用户输入的操作指令时,终端向区块链发送相关的注册请求,区块链完成对用户的验证并创建区块链账户。可选的,如上述步骤S201中用户可以是个人也可以是企业或者渠道方,如果用户是个人,则用户信息可能包括个人的姓名、性别、年龄、身份信息以及其他个人基本信息;如果用户是企业或者渠道方,则用户信息可能包括企业纳税人识别码和企业法人等信息。换句话说,只有在区块链上进行注册的个人或者企业才可以通过区块链生成针对目标交易产品的交易合同。
在一种可行的实施方式中,区块链在根据用户信息和智能合约生成交易合同之后,可检测交易合同中的各个交易流程的执行状态并更新执行状态。可选的,更新交易合同包括的各个交易流程的执行状态可以理解为通过某种方法使得当前未执行的流程执行状态由更新为已完成状态或者某个交易流程由已完成但出错的状态更新为正在进行二次验证的状态等。
本发明实施例中区块链对接收到的交易请求进行验证,在验证通过的情况下获取交易请求中包括的用户的区块链账户中的用户信息,然后根据交易请求中包括的产品标识获取交易产品对应的智能合约;进一步的,根据用户信息和智能合约生成了交易合同,并实时监测并交易合同中交易流程的执行状态,实现了针对不同交易产品,根据智能合约生成并更新交易合同,降低了开发成本,提高了交易处理的效率。
参见图3,是本发明实施例提供的另一种基于区块链的信息处理方法的示意流程图,如图所示3方法可包括:
S301、区块链接收终端发送的针对目标交易产品的交易请求。
S302、若区块链对交易请求验证通过,则获取用户的区块链账户中的用户 信息。
S303、区块链根据产品标识,获取目标交易产品对应的智能合约。
S304、区块链根据用户信息和智能合约生成交易合同。
可选的,步骤S301-S304中包括的一些可行的实施方式已经在图2所示的基于区块链的信息处理方法中具体描述,在此不再赘述。
S305、区块链获取交易合同中当前进行到的目标交易流程的执行状态。
可选的,区块链根据用户信息和智能合约生成交易合同之后,可实时监测交易合同中包括的交易流程的执行状态。可以理解的,交易合同中包括的各个交易流程是有先后执行顺序的,该执行顺序是由交易产品的特性决定的。比如交易产品A对应的交易流程的执行顺序为先风控审核再网签,交易产品B对应的交易流程的执行顺序为先网签再风控审核。也可以理解为,交易合同中交易流程是排队等待执行的,区块链获取交易合同中当前进行的目标交易流程的执行状态也即区块链获取当前排队队列中处于第一位置处的交易流程。
S306、在执行状态为未执行的情况下,区块链向目标交易流程对应的支撑区块链发送执行请求。
在一种可行的实施方式中,在S305步骤之后区块链判断目标交易流程当前所处的执行状态,执行状态可以包括“已完成”、“已审核”或者“未执行”、或者“等待执行”等。若区块链判断目标交易流程的执行状态为“已审核”,则可忽略该目标交易流程,继续监测下一交易流程;若区块链判断目标交易流程的执行状态为“未执行”,区块链向目标交流程对应的支撑服务器发送执行请求,以指示支撑服务器执行该目标交易流程。比如,区块链获取到的目标交易流程为风控审核,且目标交易流程的执行状态为未执行,则区块链向风控审核支撑服务器发送执行请求,以提示风控审核支撑服务区处理目标交易流程。
S307、区块链接收支撑服务器响应于执行请求发送的针对目标交易流程的执行结果。
S308、区块链根据执行结果更新交易合同中目标交易流程的执行状态。
在一种可行的实施方式中,在步骤S307中区块链接收到支撑服务器响应于执行请求发送的针对目标交易流程的执行结果之后,区块链根据执行结果更新交易合同中目标交易流程的执行状态,可包括:若执行结果符合预设执行状 态更新条件,则区块链将交易合同中目标交易流程的执行状态由正在处理更新为已完成。在另一种可行的实施方式中,还包括:若执行结果不符合预设执行状态更新条件,则区块链生成目标交易流程执行失败的提示信息。
换句话说,区块链接收到支撑服务器发送的执行结果后,对执行结果进行判断处理,即判断执行结果是否符合预设执行状态更新条件:如果执行结果符合预设执行状态更新条件,则区块链可对目标交易流程的执行状态进行更新;如果执行结果不符合预设执行状态更新条件,则区块链可不对目标交易流程的执行状态进行更新,并且区块链还可生成目标交易流程执行失败的提示信息,以便于后续对该目标交易流程进行其他处理。其中,预设执行状态更新条件可以是区块链为每个交易流程预先设定的,比如交易流程为风控审核时,对应的预设执行状态更新条件可以为风控审核通过,再如交易流程为网签时,对应的预设执行状态更新条件可以为网签通过。
举例来说,假设区块链获取到当前进行到的目标交易流程为风控审核,假设区块链为风控审核预设执行状态更新条件为风控审核通过。如果区块链判断风控审核流程未被执行,则可向风控审核对应的风控审核支撑服务器发送执行请求;风控审核支撑服务器接收到执行请求后,开始执行风控审核交易流程,并将执行结果返回给区块链;区块链接收到风控审核支撑服务器发送的执行结果之后,判断该执行结果是审核通过还是审核未通过;如果执行结果是审核通过,则区块链将风控审核交易流程由正在处理更新为已完成,并继续监测下一交易流程的执行状态,如果执行结果是审核未通过,则区块链生成风控审核执行失败的提示信息,用于提示用户可能导致风控审核失败的原因。若区块链接收到终端输入的重新审核请求或者终端输入的重新生成交易合同请求时,区块链重新向风控审核支撑服务器发送执行请求,或者区块链重新执行步骤S301-S308。
本发明实施例中区块链对接收到的交易请求进行验证,在验证通过的情况下获取交易请求中包括的用户的区块链账户中的用户信息,然后根据交易请求中包括的产品标识获取交易产品对应的智能合约;进一步的,根据用户信息和智能合约生成了交易合同,并实时监测交易合同中交易流程的执行状态;如果检测到目标交易流程未被执行,向目标交易流程对应的支撑服务器发送执行请 求,最后根据支撑服务器发送的执行结果更新目标交易流程,实现了针对不同交易产品,根据智能合约生成并更新交易合同,降低了开发成本,提高了交易处理的效率。
