附图说明
为了更清楚地说明本发明实施例中的技术方案,下面将对实施例描述中所需要使用的附图作简要介绍,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,对于本领域的普通技术人员来讲,在不付出创造性劳动的前提下,还可以根据这些附图获得其他的附图。

图7为本发明实施例提供的一种计算设备的硬件结构示意图。
具体实施方式
为了使本发明的目的、技术方案和优点更加清楚,下面将结合附图对本发明作进一步地详细描述,显然,所描述的实施例仅仅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它实施例,都属于本发明保护的范围。
图1为本发明实施例所适用的系统架构。参考图1所示,该系统架构可以包括客户端100、服务器200和区块链平台300。
客户端100和服务器200可以通过网络与区块链平台连接。
需要说明的是,上述图1所示的结构仅是一种示例,本发明实施例对此不做限定。
基于上述描述,图2示例性的示出了本发明实施例提供的一种基于区块链的数字资产有效期处理的方法的流程,该流程可以由基于区块链的数字资产有效期处理的装置执行。
如图2所示,该流程具体包括:
步骤201,在数字资产发放时,获取资产有效期以及发放日期时间戳和到期日期时间戳。
通过NTP(Network Time Protocol,网络时间协议)获取国家授时中心的时间同步区块链网络中各个节点的系统时间,以保证数据存放在区块链上的 时间具有可信性。
机构在数字资产发放时,设置资产有效期,在生成交易信息时自动生成发放日期时间戳及到期日期时间戳。
步骤202,根据所述资产有效期以及发放日期时间戳和到期日期时间戳,生成具有有效期属性的交易信息。
具体的,可以将资产有效期、发放日期时间戳和到期日期时间戳,写入该数字资产的交易信息,其中,交易信息中还包括修改日期时间戳。
在交易信息中预留了修改日期时间戳属性,该时间戳为从国家授时中心获取到的标准时间。
上述资产有效期以及发放日期时间戳和到期日期时间戳都写入交易信息,也就是区块链中的区块。
与现有的交易信息的区块存储记录(如图3所示)有区别的是,在区块体增加了发放时间、到期时间和更改时间,如图4所示。其中,发放时间标志资产生命周期开始时间,和资产消费操作时的优先级。到期时间标志积分到期时间,供智能合约校验。更改时间存储有效期发生更改的时间。
也就是说,为了在区块链中完成有效期的操作,需要对传统区块链上存储的交易信息内容进行设计,添加数字资产发放到用户时间、数字资产到期时间及修改时间。
步骤203,将所述具有有效期属性的交易信息存储至区块链。
在产生上述具有有效期属性的交易信息后,就可以将该交易信息进行共识后存储在区块链中。
在将具有有效期属性的交易信息存储至区块链之后,还可以获取修改资产有效期的指令,根据修改所述资产有效期的指令,对资产有效期进行修改,并将修改日期时间戳存储至所述区块链。
也就是说,若相应的机构需要对相应的资产进行修改有效期操作,则机构通过客户端调用实现编写好的更新操作的智能合约,在交易信息上添加修改日期时间戳,并修改相应有效期时间戳。
还可以定时校验到期日期是否已经到达资产有效期,若是,则执行到期操作,并将删除数字资产交易信息存储至所述区块链。
例如,可以设计相关智能合约,校验到期时间是否已经达到有效期限制,若达到则执行到期操作,添加删除资产交易信息。
相应的,可以在服务器中设计相应定时程序,通过SDK(Software development kit,软件开发工具)调用到期处理智能合约,定期执行到期数字资产的到期操作。
相应的区块链节点进行共识,即各个节点上运行智能合约对数字资产到期操作的相关信息进行验证,通过校验到期日期是否符合,则对到期操作进行共识。
在相应到期操作记录生成区块时,连接到区块链中,相应用户手中的数字资产也即宣告失效,用户无法使用。
为了保证用户能够在有效期之内尽可能的应用自己的积分,在设置时,为每笔交易信息设置优先级,也就是发放日期时间戳设有优先级。该优先级通过发放日期有效期进行标注,资产发放日期早的,则优先级高。也就是说,优先级是根据资产发放日期确定的。
为了更好的解释本发明实施例下面将通过具体的实施场景来描述基于区块链的数字资产有效期处理的流程。
如图5所示,该实施例采用以Fabric为数字积分底层区块链平台,其上部署数字积分到期操作的智能合约,修改积分有效期的智能合约,采用Go语言实现校验到期日期、相应积分到期操作记录、上链等功能。
交易信息采用图4中所示的具备有效期属性的记录,SDK采用基于开源Fabric SDK自主研发的工具,相比原始SDK,使用起来更加方便,快捷。服务器中的定时程序使用Java语言编写。
基于该系统架构,数字积分到期操作及修改有效期的步骤如下:
1、通过NTP获取国家授时中心的时间同步区块链网络中各个节点的系统时间。
2.启动服务器中的定时程序,调用连接区块链平台的SDK工具,校验相关证书完成调用;
3、SDK调用区块链网络中的负责积分有效期校验的智能合约,智能合约校验交易信息的信息,校验积分到期日期是否已到,若满足到期校验,完成相关的删除操作,此处所指删除指在区块链中增加相应删除操作记录,并非将原有区块链中的记录进行删除。
4、各节点进行共识,若校验完成,则步骤3中生成的交易信息,打包成区块,连接到区块链上。
5、用户在使用积分进行消费时,平台将会根据交易信息中的积分的发放时间先后设立优先级,优先使用先发放的将要到期的积分。
6、数字积分平台用户执行消费操作时,则不会再显示已过期积分记录。
7、机构需要进行展期操作时,需通过机构通过自己的客户端提出展期申请,区块链相应的证书校验系统,校验提起申请的客户端是否满足,若满足,则调用修改有效期智能合约,进行相关修改有效期操作。
8、区块链各节点进行校验,若校验通过,则具备修改日期属性的交易信息,将上传至区块链进行保存。
9、修改有效期后的积分,则按新的有效期进行相关积分有效期校验。
本发明实施例还提供了另一种实施场景下数字资产有效期处理的流程,在本发明实施例中,采用以以太坊为网络会员期限存证底层区块链平台,其上部署网络会员到期操作的智能合约,修改会员有效期的智能合约,采用solidity语言实现校验网络会员到期日期、相应会员到期操作记录、上链等功能。
交易信息采用结构如图4中所示的具备有效期属性的会员记录,但此处由于是网络会员,因此对应字段应为“给某用户开通某网站会员多少天”。SDK采用以太坊SDK。服务器中的定时程序使用Java语言编写。
基于此系统架构,网络会员到期操作及修改有效期的步骤如下:
1、通过NTP获取国家授时中心的时间同步区块链网络中各个节点的系统 时间。
2、启动服务器中的定时程序,调用连接以太坊区块链平台的SDK工具,校验相关证书完成调用;
3、SDK调用区块链网络中的负责网络会员有效期校验的智能合约,智能合约校验交易信息的信息,校验会员有效期是否已到,若到完成相关的删除操作,此处所指删除指在区块链中增加相应删除操作记录,并非将原有区块链中的记录进行删除。
4、区块链各节点进行共识,若校验完成,则将步骤3中生成的交易信息,打包成区块,连接到区块链上。
5、网络会员用户执行相应会员权限时,即步骤4中对应的会员权限,则用户将不再能使用。
6、如网站会员发行机构如视频网站需要进行修改会员有效期操作时,需机构通过自己的命令行客户端提出修改会员有效期申请,区块链相应的证书校验系统,校验提起申请的客户端是否满足,若满足,则调用修改有效期智能合约,进行相关修改有效期操作。
7、区块链各节点进行校验,若校验通过,则具备修改日期属性的交易信息,将上传至区块链进行保存。
8、修改会员有效期后的用户,则按新的会员有效期进行会员权限校验。
本发明实施例可以保证机构对于发放到用户手中的数字资产到期操作的可靠性。由于到期操作通过设置定时任务操作区块链网络内智能合约完成,避免了人为的干预;每笔数字资产从发放到用户手中起就具备了有效期属性,避免了积分流通过程中发行机构任意篡改数字资产有效期的可能;若是机构需要中途修改相应有效期,则相应的修改记录也会被记录在区块链上。另外由于数字资产的到期操作在区块链中完成,保证了数字资产完整生命周期在账本中都是可查的,确保了可信任性。
