在该思路的引导下,本方案实施例提供了以下可行的实施方案。
实施例一
本申请实施例给出一种资产管理方法。具体的,请参考图1,该方法包括以下步骤:
S102,根据资产转移合约,在区块链上生成数字化智能合约。
该步骤在实现时,合约双方签订的资产转移和约可以上传至区块链,然后,在区块链上通过对该资产转移合约做数字化处理,并将得到的数字化智能合约写入区块链,生成一条新的区块链条。
在区块链技术领域,智能合约特指基于预定事件触发、不可篡改、自动执行的计算机可读指令。区块链上的节点可以通过调用智能合约实现各种交易。
其中,根据智能合约的创建方式以及功能的不同,通常将智能合约分为两种类型。一种是系统内置智能合约,其特点是在区块链节点创建后即存在并可提供服务;另一种是用户外置智能合约,其特点是由用户通过调用区块链节点的API接口所创建的新的智能合约。本申请实施例所涉及的智能合约可以上述两种方式实现。
S104,当满足智能合约的资产转移条件时,对资产借贷用户进行资产状态异常检测。
其中,资产转移条件可以是合约双方签订的,如双方约定何时执行资产转移;或者,也可以是根据系统预设的规则提前配置好的,如针对双方未明确规定何时执行资产转移的场景,可以通过二者签订的数字化合约进行预设规则的处理,得到一个明确的资产转移条件,需注意,该资产转移条件还需合约双方确定认可才可执行。
在一个实现场景中,资产转移条件可以包括但不限于:资产转移时刻。
举例说明,若和约双方约定为在每个月的15日上午8时整执行资产转移,那么,每月15日上午8时整为资产转移时刻,只需当前时刻达到该资产转移时刻,就满足资产转移条件;反之,则不满足。此为合约双方约定的场景。
又例如,若合约双方约定为在每个月的15日执行资产转移,但是,并未规定具体的资产转移时刻,基于此,可以根据预设的规则,自动确定每月的15日上午9时进行资产转移,那么,该时刻被合约双方确认后,则作为该数字化智能合约的资产转移时刻,当当前时刻达到该资产转移时刻,就满足资产转移条件;反之,则不满足。此为根据系统预设的规则提前配置的一种应用场景。
可以理解的是,资产转移条件除达到资产转移时刻之外,还可以包括其他方面。例如,资产借贷用户的资产额度达到预设阈值等。
本申请实施例中,当智能合约的资产转移条件未被满足时,可以不做处 理,持续监控。反之,当判断出满足该资产转移条件时,则执行S104步骤中的异常检测步骤。并且,基于S104的检测结果不同,执行S106A或者执行S106B。
S106A,若所述资产借贷用户的资产状态异常,对资产借贷用户进行异常标记,并在区块链上进行全网广播。
本申请实施例中,异常标记是为了根据异常标记情况对资产借贷用户进行及时处理。
或者,
S106B,若所述资产借贷用户的资产状态正常,根据智能合约,对资产借贷用户的账户执行资产转移。
以下,对上述各步骤的实现方式进行具体说明。
本申请实施例中,考虑到资产借贷的实质为资产转移,因此,S104步骤中对智能合约的资产借贷用户进行资产状态异常检测主要为对资产状态的检测。基于此,本申请实施例给出以下两种不同的实现方式:
第一种方式,获取资产借贷用户的账户余额,从而,当账户余额小于智能合约规定的资产转移额度时,检测到资产借贷用户的资产状态异常。
这种实现方式简便易行,能够在账户余额小于资产转移额度时,即自动确认该资产借贷用户的资产状态异常。实现方式简便可行,具有较强的可操作性。
第二种实现方式,获取资产借贷用户的账户余额,从而,当账户余额小于智能合约规定的资产转移额度时,调取资产借贷用户在预设时间区间内的账户流水,进而,当账户流水异常时,检测到资产借贷用户的资产状态异常。
这种实现方式主要在资产借贷用户临时周转故障时,即使当前获取到的账户余额小于资产转移额度,也为其提供进一步的检测确认步骤,即通过账户流水来对此进行确认。基于此,当账户流水异常,则确认其资产状态异常,对其执行S106A的处理;反之,若账户流水正常,则确认该资产借贷用户可 能出现临时资金周转故障,则可以通过提示资产接待用户在指定时长内填补其账户月至满足资产转移额度即可。基于此,进一步的,若其在指定时长内无法填补,则可进一步确认其资产状态异常。
这种实现方式能够在当前账户余额不足时,调取一定时长内,如一年、6个月等的流水记录,从而,对当前余额不足的状态进行进一步异常判断,在一定程度上避免判断失误的可能性。
基于上述两种方式的检测判断,可以确定资产借贷用户的资产状态,基于此,一方面,在执行S106A时,请参考图2,S106A可以包括如下步骤:
S106A2,若所述资产借贷用户的资产状态异常,对资产借贷用户进行异常标记,并在区块链上进行全网广播。
除此之外,如图2所示,还可以包括以下步骤:
S106A4,对资产借贷用户进行异常标记的数目进行累计求和,得到累计异常次数。
S106A6,当累计异常次数达到预设的次数阈值,冻结资产借贷用户的资产转移权限。
S106A8,对资产借贷用户的资产转移权限已冻结的事件,在区块链上进行全网广播。
也就是说,当某一资产借贷用户进行异常标记的累计次数过多,则对此采取惩罚措施,以冻结其账户,避免被不发分子或资产借贷用户的恶意转账行为,进一步提高资产的安全性。
以及,进一步考虑到资产转移合约的双方涉及资产转移交易,因此,除对资产借贷用户进行处理之外,还可以包括以下步骤:
输出资产借贷用户的资产状态异常的提示信息至资产接收账户,以便于资产接收账户及时处理。
例如,在个人向银行的借贷系统,当确定个人账户出现账户异常时,则 通知银行该个人账户异常,以便于银行在接收到提醒时进一步采取相应的调查或处理措施。
如此,通过对资产接收账户进行提示,也能够方便资产接收账户及时对异常情况进行处理,基于此,也能够进一步依赖于合约签订双方对资产进行人工干预,提高资产安全性。
另一方面,当检测到资产状态正常时,则可以通过区块链的共识算法构建状态机系统,从而,通过状态机系统来监控并实现该数字化智能合约的高效运行。
具体的,状态机系统会自动根据该数字化智能合约规定的资产转移条件进行判断,主要用以判断该资产转移条件是否被满足。
就与此,当检测到资产借贷用户的资产状态正常时,执行S106B的资产转移步骤,在具体实现时,可以参考如下实现方式:
S106B2,根据智能合约的计算机执行代码,由区块链的共识算法构建出资产转移状态机。
S106B4,通过资产转移状态机,对资产借贷用户的账户执行资产转移。
其中,本申请实施例中,基于资产转移的实现是基于区块链的交易方法实现的。而对于一个交易而言,需要系统中所有的交易节点对此次交易进行确认并达成共识,才能判断此次交易是否成功,这样就可以保证交易的安全性。系统中所有的交易节点均是平等的。因此,将交易的信息广播到系统中所有的交易节点,然后每个交易节点对交易信息进行确认并给出确认结果。
因此,当完成一个交易时,需要所有的交易节点均对此次交易进行验证确认并且使得所有的交易节点之间均达成共识。因此,接收其他的所有的交易节点所返回的确认结果,并根据共识算法来判断交易是否成功。也即是说,共识算法是指在交易时,根据所有的交易节点所返回的结果来计算得出结果,并判断结果是否满足系统的预设条件,才能判断出交易是否成功。
若所有的交易节点达成共识,即交易成功,则执行交易;反之,若所有的交易节点未达成共识,即交易失败,则取消交易即可。这样可以保证交易的安全性,就像现有技术中通过委托第三方来对交易进行验证、监督的一样。一旦,某个交易中的一方出现问题,就可以依据该区块链中的记录来证明该交易的有效性,从而避免用户损失。
另外,共识算法可采用现有的算法来完成,比如拜占庭容错算法(PBFT,Practical Byzantine Fault Tolerance)、Ripple共识证明算法、Bitshares算法、权益证明算法、工作证明量算法(POW,Proof of Work)、股权证明机制算法(POS,Proof of Stake)、授权股权证明机制算法(DPOS,Deletegated Proof of Stake)等。
基于共识算法,就可以在区块链上构建虚拟机,作为区块链上实现智能合约、开源的底层系统,能够按照智能合约规定的条件来执行该智能合约。
基于上述资产管理方法,本申请实施例还提供了一种计算机非易失性可读存储介质,包括:计算机可读指令,当计算机可读指令被运行时用以执行如实施例一任一项所述的资产管理方法。
