Description

一种区块链网络的账号处理方法、装置、设备及存储介质
本申请要求在2018年7月18日提交中国专利局、申请号为201810790459.4的中国专利申请的优先权，该申请的全部内容通过引用结合在本申请中。
技术领域
本申请实施例涉及区块链技术领域，例如涉及一种区块链网络的账号处理方法、装置、设备及存储介质。
背景技术
现有区块链网络，按照其节点规模、共识机制和运行场景，可大致分为三种类型，即公链、联盟链和私链。各种类型的区块链网络，其都是用于生成、存储、和运行一条独立的区块链，能够处理相应的事务，存储事务数据到区块中。每条区块链所基于的区块链网络由多个节点参与，节点上部署有运行区块链技术所需的共识机制、智能合约、激励机制、以及加密算法等所需数据。通常，为了区块链的正常运行，需要节点提供算力，因此会通过发行数字货币并进行分配，来奖励节点参与区块处理和存储。同时，数字货币也可以作为区块链中事务请求处理的对象，且通常存储在区块链的账号中，典型的是比特币对应的区块链网络，比特币不仅作为对矿工节点的激励，还参与到各种交易事务中。
随着区块链技术的快速发展，区块链技术的应用场景已经不限于数字货币交易了，例如，人们不满足于仅在一个独立区块链中运行事务，或者，不再满 足于仅使用数字货币作为交易的对象或媒介，产生了不断翻新事务模式的需求，传统的区块链的类型以及区块链中的账号功能已经无法适应多种场景的需求。
发明内容
以下是对本文详细描述的主题的概述。本概述并非是为了限制权利要求的保护范围。
本申请实施例提供一种区块链网络的账号处理方法、装置、设备及存储介质，以使区块链网络以及区块链的账号功能能够与更多及更复杂应用场景的需求相匹配。

请求获取模块，用于获取与链账号关联的账号事务请求，其中，所述链账号归属于区块链；
合约写入模块，用于从所述账号事务请求中获取账号智能合约，将所述账号智能合约写入区块中，其中，所述账号智能合约用于在被执行时对所述链账号中的链元素进行操作。
第三方面，本申请实施例还提供了一种计算机设备，所述计算机设备包括：
一个或多个处理器；

具体实施方式
下面结合附图和实施例对本申请作进一步的详细说明。可以理解的是，此处所描述的具体实施例仅仅用于解释本申请，而非对本申请的限定。
另外还需要说明的是，为了便于描述，附图中仅示出了与本申请相关的部分而非全部内容。在更加详细地讨论示例性实施例之前应当提到的是，一些示例性实施例被描述成作为流程图描绘的处理或方法。虽然流程图将各项操作(或步骤)描述成顺序的处理，但是其中的许多操作可以被并行地、并发地或者同时实施。此外，各项操作的顺序可以被重新安排。当其操作完成时所述处理可以被终止，但是还可以具有未包括在附图中的附加步骤。所述处理可以对应于方法、函数、规程、子例程、子程序等等。
实施例一
图1是本申请实施例一提供的一种区块链网络的账号处理方法的流程图，本实施例可适用于区块生成节点根据智能合约对账号进行处理的情况，该方法可以由区块链网络的账号处理装置来执行，该装置可以由软件和/或硬件的方式来实现，并一般可集成在承担区块链网络节点功能的计算机设备中，区块链网络节点可以是具有区块处理权限的区块生成节点。如图1所示，该方法包括如下操作：
S110、获取与链账号关联的账号事务请求，其中，所述链账号归属于区块链。
其中，链账号可以是归属于区块链的一个账号，可以用于管理区块链中用于交易的媒介，例如数字货币或其他可以用于交易的物品等元素。链账号与现有的区块链网络中账号的区别是，可以不受用户的控制和管理，而是由智能合 约规定其操作。账号事务请求可以是区块链网络节点发起的，用于请求建立链账号的事务请求，或者也可以是请求变更链账号或进行链账号内元素操作的事务请求。元素操作一般可包括转入和转出的处理。账号事务请求用于包含或生成能够控制链账号的账号智能合约，账号智能合约被写入区块中，保证其可靠执行。
在本实施例中，可以将区块生成节点作为链账号创建者在区块链网络中创建链账号。相应的，区块生成节点首先需要获取链账号关联的账号事务请求并进行处理。链账号是归属于区块链的，其中，区块链可以是区块链网络中的一条区块链，也可以是多条区块链。区块链网络中的多条区块链可以以平行链的方式存在。
需要说明的是，在现有的区块链领域主要包括用户账号和联盟账号。其中，用户账号可以是用户自己的账号，用户与区块链网络中的节点没有严格的对应关系。也即，一个用户可以对应几个节点，一个节点也可以承载几个用户，且节点和用户之间没有固定的对应关系。用户可以通过自己的公钥和私钥管理自己的账号数据，例如，管理用户账号里的数字货币。用户可以用自己账号里的数字货币进行交易、支付手续费、进行奖励及提供冻结资金等任何操作。联盟账号可以是多人统一管理和使用的一个账号。联盟账号若想进行交易及奖励等涉及数字货币的操作，需要联盟中所有成员的同意，或大比例成员同意才能控制联盟账号的数字货币操作。联盟账号通常可以应用在联盟链中，归属于公司或机构等组织。由此可见，现有区块链网络中，账号通常可以由一个或多个用户进行管理和控制。
然而，如果区块链网络中不止存在一条区块链，而是存在多条平行链。平 行链在创建或运行的过程中，也需要一些涉及到账号中数字货币的事务。但是现有的用户账号或联盟账号无法完全匹配平行链对数字货币操作的需求。例如，创建平行链时，区块链网络中的节点由于不确定是否能够获取收益而不愿意参与并提供算力。为了鼓励节点参与创建平行链，可以由平行链创建者提供一定的数字货币奖励金进行激励。可是，由于平行链创建者对自己的用户账号或联盟账号有绝对的控制权。因此，一旦平行链创建者需要变更时，或者平行链创建者对提供的奖金反悔时，无法保证激励一定到位。
在本实施例中，可以通过在区块链网络中设置链账号，来避免用户的绝对控制权。链账号可以用于存储链元素，且链账号可以不受任何用户的控制和管理。链账号是公开透明的且没有私钥，其账号操作只能通过链账号创建时绑定的账号智能合约来控制。因此，链账号相对于现有的账号来说具备足够的公信力，能够保证对网络节点激励的有效性和可靠性。
区块链的链账号以及其账号智能合约，可以写入该条区块链本身的区块中，例如写入创世区块中。另外，也可以写入其他区块链的区块中，由其他区块链的节点来监督另一条区块链的链账号的执行。
在本申请的一个实施例中，获取与链账号关联的账号事务请求可以包括：获取创建链账号、变更链账号或链账号操作的提案事务请求；对所述提案事务请求进行处理，并根据其他区块链节点的投票结果，发起包括链账号和链账号智能合约的创建账号事务请求、变更账号事务请求或账号操作事务请求，作为所述账号事务请求，其中包括有账号智能合约。
其中，创建链账号的提案事务请求可以是区块链网络节点发起的，用于创建链账号的事务请求；变更链账号的提案事务请求可以是区块链网络节点发起 的，用于更改链账号相关信息的事务请求，如变更账号名称等；链账号操作的提案事务请求可以是区块链网络节点发起的，用于对链账号进行相关操作的事务请求，如重置账号输出规则等。提案事务请求一般适用于在链账号的区块链已经在先存在，而后创建、变更或操作链账号的情况。提案事务请求需要得到其他节点的投票支持，才能够确定账号智能合约。
创建账号事务请求可以是区块生成节点发起的，用于创建链账号或链账号智能合约的事务请求；变更账号事务请求可以是区块生成节点发起的，用于变更链账号或链账号智能合约相关信息的事务请求；账号操作事务请求可以是区块生成节点发起的，用于对链账号或链账号智能合约进行相关操作的事务请求。
在本实施例中，区块链网络中的节点在需要创建、变更或操作链账号时，可以在区块链网络中发起相应的提案事务请求。区块生成节点接收到提案事务请求后，即可对提案事务请求进行处理。示例性的，区块生成节点可以采用提案-投票的方式来处理提案事务请求，接收其他节点对提案事务请求中的相关内容的投票结果，以确定提案事务请求是否通过。例如，在投票的截止时间内，如10分钟，如果区块生成节点接收到设定比例(如2/3)数量的节点反馈的投票结果为同意，则可以确定对提案事务请求进行后续处理。区块生成节点可以根据提案事务请求的具体内容在区块链网络中重新发起相应的事务请求，以对链账号或链账号智能合约进行创建、变更或操作等处理。区块生成节点可以根据提案事务请求中规定的设定的智能合约模块进行选择和编辑，从而对账号智能合约进行更改。或者，区块生成节点还可以直接根据提案事务请求的相关内容生成满足需求的新的账号智能合约。
在本申请的一个实施例中，所述链账号的地址为自然语义字段。
其中，自然语义可以包括但不限于各类语言的词汇、字母或短句等。
在本实施例中，由于链账号不受用户的控制和管理，只要能够被节点所识别即可。因此无需对链账号设置固定长度的公钥地址和对应的私钥，可以采用自然语义字段对链账号的地址进行命名，如采用可读的英文单词等。
S120、从所述账号事务请求中获取账号智能合约，将所述账号智能合约写入区块中，其中，所述账号智能合约用于在被执行时对所述链账号中的链元素进行操作。
其中，账号智能合约可以是用于规定链账号在区块链网络中执行和运行过程的智能合约。链元素可以是链账号中用于转移的媒介，如数字货币或其他物品等。
在本实施例中，区块链网络节点需要创建链账号时，可以在区块中写入链账号的地址，同时将绑定链账号的账号智能合约作为一个账号事务请求在区块链网络中发布。区块生成节点接收到账号事务请求后，可以获取账号智能合约，并将获取的账号智能合约写入区块中。在链账号的运行过程中，可以由区块生成节点回溯历史区块，以获取链账号对应的账号智能合约，并基于账号智能合约来针对链账号进行各种操作。
本申请实施例通过获取与链账号关联的账号事务请求，从账号事务请求中获取账号智能合约，将账号智能合约写入区块中，以使区块生成节点在执行账号智能合约时，可以根据账号智能合约中的相关规定对链账号进行处理，其中，链账号归属于区块链，按照账号智能合约中的规定对链账号进行操作，无需依赖于用户对账号的操作，为区块链技术以及账号功能提供了适应多种场景需求的方式，使区块链网络以及区块链的账号功能能够与更多及更复杂应用场景的 需求相匹配。
实施例二
图2是本申请实施例二提供的一种区块链网络的账号处理方法的流程图，本实施例以上述实施例为基础进行具体化，在本实施例中，给出了获取与链账号关联的账号事务请求的具体实现方式，以及，从所述账号事务请求中获取账号智能合约，将所述账号智能合约写入区块中的同时，或之后的具体操作。相应的，如图2所示，本实施例的方法可以包括：
S210、获取平行链创建节点发起的基础链事务请求作为账号事务请求，其中，所述基础链事务请求中包括所创建的平行链的部署数据、指定输出账号和所述平行链绑定的链账号。
其中，基础链是一种区块链，可以用于在各种独立的区块链之间建立联系。基础链可以与对应的平行链进行关联，用于辅助创建平行链、管理平行链、辅助平行链进行数据交换。例如，基础链可以用于在现有的彼此独立的区块链之间建立联系，使得区块链中的数据交互不再局限于一条单独的区块链，使得价值的流动范围不再局限于一条单独的区块链。也即，基础链可以对整个区块链网络中的运行参数进行管理和监督。基础链事务请求可以是基础链网络中一段时间内发生的交易请求或其他待处理的事务请求。
平行链也是一种区块链，与基础链是相对的概念。平行链具有一般区块链的所有属性，同时，可能会基于基础链去建立、被管理以及进行数据交换。平行链可以是由基础链派生而成的，或者也可以是与基础链具有对等地位和功能，相互辅助建立、管理和数据交换。平行链可以有一条，也可以存在多条。其中， 多条平行链之间可以彼此独立，不相互影响，或者，两条平行链之间也可以是互为基础链和平行链的关系。平行链创建节点可以是创建平行链创世区块的网络节点，其也部署有基础链的数据，所以可以发起基础链事务请求。部署数据可以是区块链中数据层、网络层、共识层、激励层、合约层和应用层对应的数据，如数据区块、时间戳、传播机制、验证机制、发行机制、算法机制、智能合约或可编程货币等数据。在平行链的创世区块中也可以写入对应的智能合约，用于后续平行链中的区块生成节点，能够执行该智能合约。平行链中的智能合约，可规定由平行链配合基础链共同对链账号进行操作。例如，平行链的智能合约，规定平行链网络节点在发现满足设定条件时，向基础链发起基础链事务请求，请求基础链网络节点进行处理。基础链事务请求可以是请求基础链网络节点对链账号的链元素进行转移操作。指定输出账号可以是用于向其他账号输出链账号中链元素的账号。
通常，基础链是先于平行链建立和运行的，其具有更高的公信力和号召力，其价值更得到大家的认可。所以平行链的节点可以利用基础链节点的公信力和号召力来借助愿意提供算力的节点为其提供服务。
基础链和平行链可以组成超级链网络。在超级链网络中，基础链也可以是一条或多条。需要说明的是，参与基础链的所有节点和参与平行链的所有节点之间存在重叠关系。也即，参与平行链的至少部分节点与参与基础链的至少部分是相同的网络节点。在这些重叠的网络节点中，部署有其参与的区块链的所有数据，即，既存储有基础链的部署数据，也存储有平行链的部署数据，还同时存储有基础链和平行链的区块本身。由于同时部署有不同区块链的数据，所以这样的网络节点可以生成不同区块链的事务请求，以及还可以本地查询到不 同区块链中的事务数据，方便其进行跨链事务处理。
另外还需说明的是，基础链和平行链可以采用相同或不同类型的数字货币进行激励，且基础链和平行链的网络节点用于存储数字货币的账号可以同时存储多种不同类型的数字货币，每个区块链中的数字货币都可以与账号进行交互，如转入或转出数字货币。区块链起到激励作用的不限于数字货币，也可以是其他由账号管理的元素。
在本实施例中，链账号可以用于建立基础链和平行链之间的关联。也即，链账号可以用于对参与平行链的节点提供激励。具体的，可以由基础链网络的其中任意一个节点作为平行链创建节点，发起创建平行链创世区块的基础链事务请求，也即，平行链创建节点可以将平行链的创世区块的内容作为一个基础链的事务请求，请求基础链网络节点写入基础链的区块中，由此，基础链可以对平行链的创世区块进行监管和回溯。平行链的创世区块的内容可以参考现有区块链的创世区块的内容建立。例如，写入平行链的共识机制、激励机制、发行的数字货币以及智能合约的模板等部署数据，除此之外，还可以在平行链的创世区块中规定相应的指定输出账号和平行链绑定的链账号。并且，平行链的创世区块可以控制平行链的后期运行。由此可见，平行链创建节点在创建平行链时，即可在发起的基础链事务请求规定对参与平行链建立的节点的激励规则。
S220、从所述账号事务请求中获取账号智能合约，将所述账号智能合约写入区块中，其中，所述账号智能合约用于在被执行时对所述链账号中的链元素进行操作。
S230、执行所述账号智能合约，将指定输出账号中的基础链元素转移到所述链账号中。
在本实施例中，可以将基础链事务请求中的指定输出账号中包括的基础链元素转移到链账号中，作为链账号中的链元素凭借基础链的价值发挥激励作用。
在本申请的一个实施中，所述账号智能合约用于在被执行时对所述链账号中的链元素进行操作可以包括下述至少一种：
当账号智能合约被执行时，由其他账号将链元素输入所述链账号中；
当账号智能合约被执行时，按照账号智能合约中规定的规则，从链账号将链元素转移到区块链的其他账号中。
在本实施例中，账号智能合约被执行时可以执行以下功能：
首先，区块链网络中的已有账号，如用户账号和联盟账号，向链账号输入初始数量的链元素。如果区块链网络是超级链网络，则通常情况下可以由平行链创建节点所持有的账号向链账号中输入初始数量的链元素。其中，向链账号输入的链元素可以是基础链或平行链中已经布局存在的链元素。在一实施例中，鉴于基础链具有足够的公信力，可以将基础链中流通的链元素输入链账号中，以避免其他节点不认可链元素的价值，起不到激励作用。
其次，链账号在运行过程中，可以按照账号智能合约中规定的规则，从链账号将链元素转移到区块链的其他账号中。示例性的，平行链创建节点在创建平行链时，可以从链账号按照账号智能合约中的规则，向参与平行链创建的节点对应的账号转移一定量的链元素。如，采用平均分配的方式将链账号中设定数量的链元素平均分配给参与平行链创建的节点对应的账号。
在本申请的一个实施中，所述账号智能合约中规定的规则可以包括下述至少一种：
对于设定数量历史区块的区块生成节点，按照算力贡献规则进行设定数值 链元素的分配；
对于区块链网络中的节点，按照平均规则进行设定数值链元素的分配。
其中，设定数量可以是根据实际需求设定的数值，例如10、20或50等，本实施例对此并不进行限制。算力贡献规则可以是人为规定的，用于衡量提供算力的强弱程度的节点所占有权重值或排序等。例如，在前5个区块生成节点中，各个区块生成节点提供的算力的权重值为0.1、0.2、0.3、0.2和0.2，或者在前5个区块生成节点中，各个区块生成节点提供的算力由强到弱的顺序依次为：区块生成节点1、区块生成节点3、区块生成节点2、区块生成节点5以及区块生成节点4。设定数值同时可以是根据实际需求设定的数值，例如100或200等，具体需要依据区块链中包括的链元素的总量进行适应性设定，本实施例对此同样不进行限制。链元素的分配比例可以是针对区块链网络节点所制定的，用于分配链元素的比例值。通常在区块链的运行过程中，会为每个区块的区块生成节点奖励一定的数字货币，即分配数字货币。通常会随着区块的数量增多，而有一定的衰减。在分配链元素时可以参照链数字货币的分配比例，进行相应比例的分配。平均规则可以是为所有参与平行链的节点平均分配的方式。
在本实施例中，账号智能合约中规定的规则可以包括以下几种情况：
首先，可以依据区块生成节点的数量以及算力贡献规则对区块生成节点分配设定数值的链元素。当区块链网络为超级链网络时，基础链网络节点可以通过执行账号智能合约，查询本地存储的平行链中的区块数据以获取平行链中区块生成节点信息。示例性的，如果将比特币作为基础链元素，且当平行链网络中区块生成节点的数量每达到10个时，则可将100个比特币按照10个区块生成节点提供算力的强弱程度进行分配。如果10个区块生成节点提供的算力的权 重值分别为0.05、0.1、0.15、0.1、0.1、0.2、0.05、0.1、0.05和0.1，则为10个区块生成节点分别分配5、10、15、10、10、20、5、10、5和10个比特币。
当然，也还可以直接按照平均规则对区块链网络中的节点分配设定数值的链元素。示例性的，当区块链网络为超级链网络时，平行链中总共存在15个节点，可以将300个基础链中的比特币平均分配给15个节点，每个节点分配到20个比特币。
需要说明的是，图2仅是一种实现方式的示意图，S220与S230之间并没有先后顺序关系，可以先实施S220，再实施S230，也可以两者并行实施。
采用上述技术方案，通过获取平行链创建节点发起的基础链事务请求作为账号事务请求，从账号事务请求中获取账号智能合约，将账号智能合约写入区块中，以使区块生成节点在执行账号智能合约时，可以根据账号智能合约中的相关规定对链账号进行处理，其中，链账号归属于区块链，且按照账号智能合约中的规定对链账号进行操作，无需依赖于用户对账号的操作，为区块链技术以及账号功能提供了适应多种场景需求的方式，使区块链网络以及区块链的账号功能能够与更多及更复杂应用场景的需求相匹配。
