发明背景
通常来说，区块链技术是一种全新的分布式基础架构与计算方式，其利用块链式数据结构来验证与存储数据，利用分布式节点共识算法来生成和更新数据，利用密码学方式保证数据传输和访问的安全，以及利用由自动化脚本代码组成的智能合约来编程和操作数据。区块链网络是去中心化的网络，是一种P2P(Peer-to-Peer)网络。区块链网络中不存在中央化的服务和层级结构，每个节点都是对等的节点，各个节点共同提供网络服务。区块链网络中的节点既是客户端，还是服务器。
在现有技术中，在区块链服务器正常运行时，通常将区块链服务器的电源输出电压维持在预设的固定电压值，并没有针对电源输出电压的优化机制。然而，电源输出电压过高会浪费功耗，而过低可能导致区块链服务器的算力及稳定性受到影响。

实施方式
为使本申请的目的、技术方案和优点更加清楚，下面结合附图对本申请作进一步的详细描述。
为了描述上的简洁和直观，下文通过描述若干代表性的实施方式来对本申请的方案进行阐述。实施方式中大量的细节仅用于帮助理解本申请的方案。但是很明显，本申请的技术方案实现时可以不局限于这些细节。为了避免不必要地模糊了本申请的方案，一些实施方式没有进行细致地描述，而是仅给出了框架。下文中，“包括”是指“包括但不限于”，“根据……”是指“至少根据……，但不限于仅根据……”。由于汉语的语言习惯，下文中没有特别指出一个成分的数量时，意味着该成分可以是一个也可以是多个，或可理解为至少一个。
申请人发现，在现有技术中，通常将区块链服务器的电源输出电压维持在预设的固定电压值。这至少具有如下缺点：固定电压值过高会浪费功耗，固定电压值过低可能导致区块链服务器的算力及稳定性受到影响。因此，将电源输出电压维持在既可以保证算力及稳定性，还节约功耗的目标电压值是亟需的技术手段。
基于上述分析，图1为根据本申请实施方式的电源电压控制方法的示范性流程图。
如图1所示，该方法包括：
步骤101：基于第一数值与第二数值的比值，确定电压确定参数，其中，所述第一数值为区块链服务器中处于工作状态的核的数目，所述第二数值为所述区块链服务器中的核的总数目。
本步骤中，电压确定参数是指用于后续确定区块链服务器的电源的目标电压值的参数。
在一个实施方式中，该方法还包括：基于区块链服务器中的芯片数以及每个芯片所包含的核数，确定第二数值。
在一个实施方式中，该方法还包括：向区块链服务器中的所有核，分别发送计算任务，统计执行计算任务以返回指定随机数的核，将统计出的核的数目确定为第一数值。
其中，指定随机数可以为只被使用一次的任意随机数或非重复的随机数，具体指符合Nonce难度要求的随机数。例如，返回结果为Nonce(其全称为Number used once或Number once)，返回的Nonce符合虚拟货币挖掘的难度要求，每个Nonce都是核执行遍历操作后得到的结果。
比如，假定区块链服务器中包含300个相同类型的芯片，且每个芯片包含600个核，则第二数值为：300*600＝180000，即共有180000个核。
当区块链服务器启动后，先经历升频阶段，再进入芯片频率不变的工作状态。向工作状态的区块链服务器中的所有核，分别发送计算任务。然后，统计执行计算任务以返回Nonce的核，将执行计算任务以返回Nonce的核的数目确定为第一数值。例如，区块链服务器中的控制板向180000个核分别下发计算任务，并统计执行计算任务以返回Nonce的核有170000个，则区块链服务器中处于工作状态的核的数目为170000，即第一数值为170000。
在一个实施方式中，可以将第一数值与第二数值的比值，确定为电压确定参数。此时，电压确定参数为区块链服务器中处于工作状态的核的数目与区块链服务器中的核的总数目的比值。也就是：电压确定参数＝(区块链服务器中处于工作状态的核的数目)/(区块链服务器中的核的总数目)。比如，第一数值为170000，第二数值为180000，电压确定参数＝(170000/180000)＝0.944。
在另一个实施方式中，以第一数值与第二数值的比值为计算因子，针对该计算因子执行数学运算(比如，乘以固定系数或除以固定系数，等等)以确定出电压确定参数。
在区块链服务器的工作状态下，第二数值通常是固定不变的，第一数值可以发生变化。可以持续检测第一数值与第二数值的实时比值，以作为电压确定参数的实时值。
以上示范性描述了确定第一数值、第二数值和电压确定参数的典型实例，本领域技术人员可以意识到，这种描述仅是示范性的，并不用于限定本申请实施方式的保护范围。
步骤102：基于电压确定参数，确定区块链服务器的电源的目标电压值。
在这里，目标电压值为区块链服务器的电源输出电压的理想值。目标电压值可以保证算力及稳定性，还节约功耗。
申请人经过大量研究，确定电压确定参数与区块链服务器的电源电压之间具有映射关系。而且，区块链服务器包含latch(锁存器)芯片或非latch芯片时，电压确定参数与电源电压之间的映射关系会有不同。latch是一种在异步时序电路系统中对输入信号电平敏感的单元，用来存储信息。在数据未锁存时，锁存器中输出端的信号随输入信号变化，就像信号通过一个缓冲器；一旦锁存信号有效，数据被锁存时，输入信号不起作用。当区块链服务器采用非latch芯片时，通常可以克服芯片漏电问题；当区块链服务器采用latch芯片时，通常具有芯片漏电问题。
图2为根据本申请实施方式的包含非latch芯片的区块链服务器的电压确定参数与电源电压的映射关系示意图。
区块链服务器10、区块链服务器11和区块链服务器12分别采用不同规格的非latch芯片，而且区块链服务器10、区块链服务器11和区块链服务器12分别处于升频阶段后的工作状态(芯片频率不变)。可见，当电源电压较小时，区块链服务器10、区块链服务器11和区块链服务器12的电压确定参数随着电源电压的增大而提升，具体提升方式可以为线性提升或非线性提升，本申请实施方式对此并无限定。
在图2中，当电源电压增大到大于点A时，区块链服务器10的电压确定参数将不再随着电源电压的增大而提升，而是保持不变；当电源电压增大到大于点B时，区块链服务器11的电压确定参数将不再随着电源电压的增大而提升，而是保持不变；当电源电压增大到大于点C时，区块链服务器12的电压确定参数将不再随着电源电压的增大而提升，而是保持不变。
因此，点A处的电源电压即为区块链服务器10的目标电压；点B处的电源电压即为区块链服务器11的目标电压；点C处的电源电压即为区块链服务器12的目标电压。
图3为根据本申请实施方式的包含latch芯片的区块链服务器的电压确定参数与电源电压的映射关系示意图。
区块链服务器20、区块链服务器21和区块链服务器22分别采用不同规格的latch芯片，而且区块链服务器20、区块链服务器21和区块链服务器22分别处于升频阶段后的工作状态(芯片频率不变)。可见，当电源电压较小时，区块链服务器20、区块链服务器21和区块链服务器22的电压确定参数随着电源电压的增大而提升，具体提升方式可以为线性提升或非线性提升，本申请实施方式对此并无限定。
当电源电压增大到大于点A时，区块链服务器20的电压确定参数将不再随着电源电压的增大而提升，而是先保持不变，然后随着电源电压的继续增大而
下降。当电源电压增大到点B时，区块链服务器21的电压确定参数将不再随着电源电压的增大而提升，而是先保持不变，然后随着电源电压的继续增大而下降；当电源电压增大到点C时，区块链服务器22的电压确定参数将不再随着电源电压的增大而提升，而是先保持不变，然后随着电源电压的继续增大而下降。
因此，点A处的电源电压即为区块链服务器20的目标电压；点B处的电源电压即为区块链服务器21的目标电压；点C处的电源电压即为区块链服务器22的目标电压。
在一个实施方式中，步骤102包括：以预定的电压调节步长(比如，10毫伏)，逐步增加电源的电压值；当电压值增加到电压确定参数保持不变或开始下降时，以电压调节步长，逐步降低电压值；当电压值降低到电压确定参数开始下降时，将电源的当前电压值与单个的电压调节步长的求和结果，确定为目标电压值。这个实施方式可以适用于包含非latch芯片或latch芯片的区块链服务器。
举例(1)：当区块链服务器包含非latch芯片时，比如以图2中的区块链服务器10为例进行说明。无论区块链服务器10的电源的当前电压值为多少，以预定的电压调节步长(比如，10毫伏)，逐步增加电源的电压值；当电压值增加到电压确定参数保持不变时(此时可能刚到达点A或已经过了点A)，以电压调节步长，逐步降低电压值；当电压值降低到电压确定参数开始下降(此时到达点A的前一个点)时，将电源的当前电压值与单个的电压调节步长的求和结果，确定为目标电压值。
举例(2)、当区块链服务器采用latch芯片时，比如以图3中的区块链服务器20为例进行说明。无论区块链服务器20的电源的当前电压值为多少，以预定的电压调节步长(比如，10毫伏)，逐步增加电源的电压值；当电压值增加到电压确定参数保持不变时(此时可能刚到达点A，或已经过了点A但尚未到达电压确定参数的下降区间)时，以电压调节步长，逐步降低电压值；当电压值降低到电压确定参数开始下降(此时到达点A的前一个点)时，将电源的当前电压值与单个的电压调节步长的求和结果，确定为目标电压值。
举例(3)、当区块链服务器采用latch芯片时，比如以图3中的区块链服务器21为例进行说明，无论电源的当前电压为多少，以预定的电压调节步长(比如，10毫伏)，逐步增加电源的电压值；当电压值增加到电压确定参数开始下降时(此时已到达电压确定参数的下降区间，即已经过了G点)，以电压调节步长，逐步降低电压值；当电压值降低到电压确定参数开始下降(电压确定参数经历了先增加、再保持不变，最后开始下降的阶段)时，认定此时到达点B的前一个点，将电源的当前电压值与单个的电压调节步长的求和结果，确定为所述目标电压值。
因此，本申请实施方式直接以增加电源的电压值的调节方式，确定目标电压值，降低了确定目标电压值的难度。
优选地，步骤102还包括：记录区块链服务器在启动后升频阶段中的电压确定参数的最大值；将最大值确定为目标值。
后续，本申请实施方式通过将电压确定参数与目标值进行比较，可以简化目标电压值的确定过程。
图4为根据本申请实施方式的包含非latch芯片的区块链服务器的电压确定参数与芯片频率的映射关系示意图。
在图4中，区块链服务器30、区块链服务器31和区块链服务器32分别采用不同规格的非latch芯片，而且区块链服务器30、区块链服务器31和区块链服务器32分别处于启动后的升频阶段(电源的输出电压不变)。可见，当芯片频率较小时，区块链服务器30、区块链服务器31和区块链服务器32的电压确定参数持续为最大值。当芯片频率继续增大到点D后，区块链服务器30的电压确定参数将开始降低；当芯片频率增大到点E后，区块链服务器31的电压确定参数将开始降低；当芯片频率增大到点F后，区块链服务器32的电压确定参数将开始降低。
因此，点D处的电压确定参数被记录为启动后升频阶段中的电压确定参数的最大值，即为针对区块链服务器30、与电压确定参数进行比较的目标值；点E处的电压确定参数被记录为启动后升频阶段中的电压确定参数的最大值，即为针对区块链服务器31、与电压确定参数进行比较的目标值；点F处的电压确定参数被记录为启动后升频阶段中的电压确定参数的最大值，即为针对区块链服务器32、与电压确定参数进行比较的目标值。
图5为根据本申请实施方式的包含latch芯片的区块链服务器的电压确定参数与芯片频率的映射关系示意图。
在图5中，区块链服务器40、区块链服务器41和区块链服务器42分别采用不同规格的latch芯片，而且区块链服务器40、区块链服务器41和区块链服务器42分别处于启动后的升频阶段(电源的输出电压不变)。可见，当芯片频率较小时，区块链服务器40、区块链服务器41和区块链服务器42的电压确定参数随着芯片频率的增大而提升。提升方式可以为线性提升或非线性提升，本申请实施方式对此并无限定。
当区块链服务器40的芯片频率增大到大于点A时，区块链服务器40的电压确定参数将不再随着芯片频率的增大而提升，而是在区间[A，D]内先保持不变，并且过D点后随着芯片频率的增大而下降。当区块链服务器41的芯片频率增大到大于点B时，区块链服务器41的电压确定参数将不再随着芯片频率的增大而提升，而是在区间[B，E]内先保持不变，并且过E点后随着芯片频率的增大而下降。当区块链服务器42的芯片频率增大到大于点C时，区块链服务器42的电压确定参数将不再随着芯片频率的增大而提升，而是在区间[C，F]内先保持不变，并且过F点后随着芯片频率的增大而下降。
因此，点D处的电压确定参数被记录为启动后升频阶段中的电压确定参数
的最大值，即为针对区块链服务器40、与电压确定参数进行比较的目标值；点E处的电压确定参数被记录为启动后升频阶段中的电压确定参数的最大值，即为针对区块链服务器41、与电压确定参数进行比较的目标值；点F处的电压确定参数被记录为启动后升频阶段中的电压确定参数的最大值，即为针对区块链服务器42、与电压确定参数进行比较的目标值。
上述详细描述了确定区块链服务器的目标值的具体方式，下面描述基于电压确定参数与目标值的比较过程，确定目标电压值的具体过程。
在一个实施方式中，步骤102包括：当电压确定参数等于目标值时，以预定的电压调节步长，逐步降低电源的电压值；当电压值降低到电压确定参数开始下降时，将电源的当前电压值与单个的电压调节步长的求和结果，确定为目标电压值。这个实施方式可以适用于包含非latch芯片或latch芯片的区块链服务器。
可见，当电压确定参数等于目标值时，可以判定电压值可能偏高，因此直接执行降压调节过程，无需再执行升压调节过程。
举例(1)：当区块链服务器包含非latch芯片时，比如以图2中的区块链服务器10为例进行说明。如果当前的电压确定参数等于目标值时，可以认定当前的电源电压必然大于或等于A点时的电压，因此直接执行降压调节过程。降压调节过程具体包括：以电压调节步长(比如，10毫伏)，逐步降低电源的电压值；当电压值降低到电压确定参数开始下降(此时到达点A的前一个点)时，将电源的当前电压值与单个的电压调节步长的求和结果，确定为目标电压值。
举例(2)、当区块链服务器采用latch芯片时，比如以图3中的区块链服务器20为例进行说明。如果当前的电压确定参数等于预定的目标值时，可以认定当前的电压必然大于或等于A点时的电压，因此直接执行降压调节过程。降压调节过程具体包括：以电压调节步长(比如，10毫伏)，逐步降低电压值；当电压值降低到电压确定参数开始下降(此时到达点A的前一个点)时，将电源的当前电压值与单个的电压调节步长的求和结果，确定为所述目标电压值。
在一个实施方式中，步骤102包括：当电压确定参数小于预定的目标值时，以预定的电压调节步长，逐步增加电源的电压值；当电压值增加到电压确定参数保持不变时，将电源的当前电压值减去单个的电压调节步长的结果，确定为目标电压值；当电压值增加到电压确定参数开始下降时，以电压调节步长，逐步降低电压值，当电压值降低到电压确定参数先增加、再保持不变、继而开始下降时，将电源的当前电压值与单个的电压调节步长的求和结果，确定为目标电压值。
可见，当电压确定参数小于预定的目标值时，可以判定当前电压值位于电压确定参数的下降或上升区间，而排除位于电压确定参数不变区间的情形，因此可以基于下降或上升区间，针对性地确定目标电压值。这个实施方式可以适用于包含非latch芯片或latch芯片的区块链服务器。
举例(1)：当区块链服务器包含非latch芯片时，比如以图2中的区块链服务器10为例进行说明。如果当前的电压确定参数小于预定的目标值时，可以认定当前的电压必然小于A点时的电压，因此直接执行升压调节过程。升压调节过程具体包括：以电压调节步长(比如，10毫伏)，逐步增加电压值；当电压值增加到电压确定参数保持不变(此时到达点A的后一个点)时，将电源的当前电压值减去单个的电压调节步长的结果，确定为目标电压值。
举例(2)、当区块链服务器采用latch芯片时，比如以图3中的区块链服务器21为例进行说明。如果当前的电压确定参数小于预定的目标值时，可以认定当前的电压必然不处于区间[B，G]内。首先，以预定的电压调节步长，逐步增加电源的电压值；当电压值增加到电压确定参数保持不变(即到达区间[B，G])时，此时到达点B的后一个点，将电源的当前电压值减去单个的电压调节步长的结果，确定为目标电压值；当电压值增加到电压确定参数开始下降时(即过了G点)，以电压调节步长，逐步降低电压值；当电压值降低到电压确定参数先增加(即回到G点的过程)、再保持不变(即从G点到B点的移动过程)，继而开始下降(此时到达点B的前一个点)时，将电源的当前电压值与单个的电压调节步长的求和结果，确定为目标电压值。
步骤103：控制所述电源输出电压的值为所述目标电压值。
因此，区块链服务器的电源可以将输出电压维持在目标电压值，既可以保证算力及稳定性，还节约功耗。
