Description

许可区块链的去中心化动态优化方法、系统、设备及介质 技术领域
本发明涉及区块链优化技术领域,尤其是涉及一种许可区块链的去中心化动态优化方法、系统、设备及介质。
背景技术
目前,有关动态区块链优化的方法逐年增多。区块链是复杂的动态系统,其性能特征受底层系统状态的影响。因此,这些有关动态区块链优化的方法旨在动态调整区块链系统的配置,以在遇到的各种系统状态下实现性能最大化。
但是由于区块链的理念是,单一实体不得控制区块链系统状态。系统参与者必须共同商定任何影响系统状态的操作。因此,进行动态区块链优化不能由单一机构处理。因为如果进行单点控制,恶意的或被破坏的中心化优化服务可以强制执行脆弱的配置,试图控制区块链系统或向区块链添加恶意交易。所以目前还是急需一种去中心化方法来实现动态区块链优化。

本发明的描述中,需要说明的是,除非另有明确的限定,设置、安装、连接等词语应做广义理解,所属技术领域技术人员可以结合技术方案的具体内容合理确定上述词语在本发明中的具体含义。
下面将结合附图对本发明的技术方案进行清楚、完整的描述,显然,以下所描述的实施例是本发明一部分实施例,并非全部实施例。
对本申请实施例进行进一步详细说明之前,对本申请实施例中涉及的场景进行说明,下面以一些实际例子说明本申请实施例的应用场景。
参照图1,图1描述了一个许可区块链系统的通用架构,包括中心化优化服务100、节点101、区块链102、事务处理池103、共识协议(数据)104、块生成器节点105和点对点网络106,该许可区块链系统的通用架构依靠中心化优化服务实现动态重配置。在该许可区块链系统中,节点101生成并向区块链系统广播交易。广播交易被块生成器节点105捕获,节点101有权参与共识过程,以得到共识协议104。在被纳入数据块之前,交易被认为是未经确认的,并存储在节点的事务处理池103中等待纳入。为了实现重新配置,系统依赖于中心化优化服务100,该服务定期观察系统状态,根据最新状态计算优化决策,并将其提供给中心化优化服务100。许可区块链是指通过许可网络运行的区块链系统。与任何人都可以匿名参与的无权限区块链系统相比,有权限区块链系统要求节点的身份必须经过身份验证服务的验证才能参与系统。本发明的许可区块链的去中心化动态优化方法适用于有权限的区块链系统。因此在本申请实施例中,区块链都默认为许可区块链。
参照图2,图2描述了本发明的许可区块链的去中心化动态优化方法如何应用于许可区块链系统,相对于许可区块链系统的通用架构,增加了优化链200、共识协议(优化)201、优化框架202和优化节点203,本申请的实施例均可应用于图2所描述的场景。
参照图3,在本发明的一些实施例中,提供了一种许可区块链的去中心化动态优化方法,包括:
步骤S100、获取许可区块链的系统状态。
步骤S200、构建优化节点、优化框架和优化链;其中,优化框架包括区块链配置优化算法;每个优化节点包括优化框架提供的一个实例。
需要说明的是,优化框架相当于一个黑盒,可以是一个完整的区块链优化解决方案,而区块链优化解决方案的核心为区块链配置优化算法。例如,一种基于深度Q学习(DQL)的优化算法,通过该协议可以对区块生产者、共识算法、区块大小和区块间隔进行优化。动态 调整,提高底层区块链的可扩展性,同时不影响系统的去中心化、延迟和安全性。集成时,每个优化节点将包含区块链配置优化算法的一个实例,其中,对于每个优化节点是否需要使用同一区块链配置优化算法,此处不作限制。参照图9,区块链配置优化算法还能包括《Performance Optimization for Blockchain-Enabled Industrial Internet of Things(IIoT)Systems:A Deep Reinforcement Learning Approach》、《Digital twin for dynamic management of blockchain systems》和《PBRL-TChain:A performance-enhanced permissioned blockchain for time-critical applications based on reinforcement learning》描述的区块链配置优化算法,同时对应的,不同区块链配置优化算法的输入和输出的数据类型可能不同,因此对应的优化块的区块结构不相同,此处优化块的区块结构相应会进行调整,对于区块结构此处不作限制。其中,《Performance Optimization for Blockchain-Enabled Industrial Internet of Things(IIoT)Systems:A Deep Reinforcement Learning Approach》收录于IEEE工业信息学汇刊,提出了一种基于深度Q学习的优化协议,通过该协议可以对区块生产者、共识算法、区块大小和区块间隔进行优化。动态调整,提高底层区块链的可扩展性,同时不影响系统的去中心化、延迟和安全性。《Digital twin for dynamic management of blockchain systems》是指基于数字孪生体的区块链系统动态管理系统,在arXiv中有收录相关的算法。《PBRL-TChain:A performance-enhanced permissioned blockchain for time-critical applications based on reinforcement learning》是指一种基于强化学习的针对时间关键型应用的性能增强许可区块链,常用于TChain这种基于区块链的底层公有链协议。由于举例算法均收录于英文期刊,因此输入(Input)和输出(Output)也通过英文期刊中的变量描述进行表达。
步骤S300、将系统状态输入实例生成对应的优化块;优化块包括通过区块链配置优化算法得到的优化系统配置信息。
步骤S400、通过每个优化节点对优化块进行共识验证,得到优化块的共识证明结果。
步骤S500、根据共识证明结果将优化块存储至优化链。
步骤S600、根据已存储优化块的优化链对许可区块链进行配置优化。
本方法首先通过许可区块链的系统状态对应地构建优化节点、优化框架和优化链,实现了一个良好的动态调整架构,能够实时根据许可区块链的系统状态进行调整,也适用于更多任务场景并易迁移;其次,通过实例生成对应的优化块,由于实例是通过优化框架提供的,因此相应的实例也是能够通过优化框架进行调整,通过实例能够实现不同许可区块链配置优化算法得到优化块,提高优化块生成的鲁棒性;然后通过每个优化节点对优化块进行共识验证,将每个优化节点进行优化块地决策,实现去中心化;再然后通过优化链存储优化块,方 便许可区块链调取优化块中的配置信息,同时也能通过优化链实现优化块的加密以及优化可追踪。最后根据已存储优化块的优化链对许可区块链进行配置优化,结合实现了动态许可区块链优化能力的同时保持去中心化关键属性的优势。
参照图4,在本发明的一些实施例中,将系统状态输入实例生成对应的优化块,包括以下步骤:
步骤S310、通过预设的提议者选择算法从所有优化节点选取得到提议者节点。
需要说明的是,从所有优化节点选取得到提议者节点,可以要求对每个优化节点进行轮询,还可以进行优化节点已选取次数等的阈值限定,此处不作具体限制。
步骤S320、将系统状态输入提议者节点对应的实例,计算得到优化块。
需要说明的是,通过实例进行区块链配置优化算法计算,会得到优化后的配置信息,将配置信息通过优化块存储。
通过提议者选择算法选取提议者节点,能够实现去中心化的效果。同时根据提议者选择算法的不同,适应更多的区块链任务场景以及不同维度的精度要求,提高优化块生成的安全性和效率。
参照图5,在本发明的一些实施例中,通过每个优化节点对优化块进行共识验证,得到优化块的共识证明结果,包括以下步骤:
步骤S410、通过提议者节点开启共识过程;共识过程使用预设的共识协议。
需要说明的是,本实施例中的共识协议是针对优化块的共识协议,即共识协议(优化)201。
步骤S420、将提议者节点以外的其他优化节点作为共识过程的验证者节点。
步骤S430、若验证者节点接收到优化块并且验证者节点验证优化块对许可区块链优化有效,修改共识证明结果为通过共识验证;若验证者节点在时间阈值内没有接收到优化块或者验证者节点验证优化块对许可区块链优化无效,修改共识证明结果为没有通过共识验证。
通过预设的共识协议,将提议者节点和其他优化节点均进行共识,保证去中心化的落实;同时通过验证者节点模拟验证优化块对许可区块链优化的有效性,进一步保障优化块的优化效果。
参照图6,在本发明的一些实施例中,通过验证者节点验证优化块对许可区块链优化有效或无效,包括以下步骤:
步骤S431、根据许可区块链的系统状态验证提议者节点的签名,并验证优化块的区块结构;若提议者节点的签名匹配并且优化块的区块结构正确,通过验证者节点使用优化块进行 配置优化得到优化结果。
需要说明的是,在成为提议者节点之前,作为优化节点就具有自身的签名,在成为提议者节点之后,变化的只有一些时间戳信息,而签名的哈希数据是不会变化的,因此可以通过验证提议者节点的签名是否匹配,来得到提议者节点的身份验证结果;同时优化块是通过实例进行区块链配置优化算法计算得到,因此优化块的信息是根据许可区块链拥有的配置决定的,因此优化块的区块结构也跟许可区块链拥有的配置相关,因此能够通过优化块的区块结构,来得到优化块的身份验证结果。最后提议者节点的身份验证结果和优化块的身份验证结果均通过后,通过验证者节点使用优化块进行配置优化得到优化结果,验证者节点使用优化块进行配置优化可以通过模拟验证器实现,此处不作具体限制。
步骤S432、对优化结果和提议者节点的优化块进行较准,若优化结果和优化块符合,优化块对区块链优化有效;否则优化块对区块链优化无效。
需要说明的是,优化结果相当于模拟结果,而优化块则存储了通过优化块理论得到的优化配置信息,如果优化结果和优化块的优化配置信息不符合,则很有可能优化块在传输中被恶意篡改,因此在本步骤中,需要对优化结果和优化块进行较准。
通过提议者节点的身份验证结果、优化块的身份验证结果和优化结果的多重验证,进一步保障优化块的安全性和有效性。
参照图7,在本发明的一些实施例中,根据共识证明结果将优化块存储至优化链,包括以下步骤:
步骤S510、检测共识证明结果。
步骤S520、若共识证明结果为通过共识验证,将共识证明结果对应的优化块存储至优化链。
根据共识证明结果判断是否存储优化块,能够节省一定的算力资源,同时也避免了无效优化块进行许可区块链的优化,浪费大量的算力资源。
参照图8,在本发明的一些实施例中,根据已存储优化块的优化链对许可区块链进行配置优化,包括以下步骤:
步骤S610、获取已存储优化块的优化链中的最新优化块。
步骤S620、对比最新优化块和许可区块链当前配置,若最新优化块和许可区块链当前配置不相同,通过最新优化块更新许可区块链。
需要说明的是,获取优化链中的最新优化块,可以在许可区块链进行每次交易之前或者在许可区块链每次交易结束后,还可以设置时间周期,此处不作具体限制。
通过实时监测优化链的最新优化块和许可区块链当前配置,保障许可区块链当前配置为最新优化块,提高许可区块链的吞吐量。
在本发明的一些实施例中,提议者选择算法包括round-robin算法和Sticky-proposer算法。
需要说明的是,提议者选择算法为round-robin算法时,提议者节点在每个优化块生成后更新,使得每个优化节点均会遍历成为提议者节点。提议者选择算法为Sticky-proposer算法时,一个提议者节点产生所有优化块,除非剩余的优化节点检测到错误或者恶意节点,则启动提议者节点更改投票,将投票结果指定的优化节点作为新的提议者节点。
根据round-robin算法和Sticky-proposer算法能够实现多种提议者选择方式,同时round-robin算法和Sticky-proposer算法为主流选择算法,能提供稳定且公正的选举方式。
参照图10,本发明的一个实施例,还提供了一种许可区块链的去中心化动态优化系统,包括区块链系统模块1001、去中心化动态优化模块1002、优化块生成模块1003、共识验证模块1004、优化链存储模块1005和区块链配置优化模块1006,其中:
