附图说明
图1是本发明实施例一提供的一种去中心化芯片研发交易数据存储方法的流程图；
图2是本发明实施例六提供的另一种去中心化芯片研发交易数据存储方法的流程图；
图3是本发明实施例七提供的一种去中心化芯片研发交易数据存储系统的示意图。
具体实施方式
为使本发明实施例的目的、技术方案和优点更加清楚，下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本发明的一部分实施例，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的前提下所获得的所有其他实施例，都属于本发明保护的范围。
实施例一
如图1所示，本发明实施例提供的一种去中心化芯片研发交易数据存储方法，可以包括以下步骤：
步骤101：对于交易节点集群中的任一交易节点，第一交易节点广播有针对一 芯片研发交易目标的至少一个芯片研发交易需求时，执行步骤102，其中，区块链上存储有针对所述芯片研发交易目标的智能合约，所述智能合约中记录有针对每一个所述芯片研发交易需求的交易执行触发条件。
步骤102：针对每一个所述芯片研发交易需求均执行：根据所述当前芯片研发交易需求的交易执行触发条件，在确定出所述第一交易节点和第二交易节点之间，发生有针对当前芯片研发交易需求的芯片研发交易时，根据所述智能合约，针对所述第一交易节点和所述第二交易节点执行相应交易操作，以获取针对所述芯片研发交易的交易数据、智能合约消息数据和芯片研发数据。
步骤103：利用分布式链下存储系统，存储预设时间段内获取到的所有芯片研发数据。
步骤104：利用所述区块链，存储所述预设时间段内获取到的所有交易数据和所有智能合约消息数据。
需要说明的是，交易记录的防篡改和芯片研发交易相关数据的可追溯是实现去中心化芯片研发交易模式的根本要求。本实施例中，区块链是实现集成电路去中心化组织研发模式和交易模式的核心关键。此外，考虑到芯片研发交易的实际应用需求和特点，提出基于智能合约的区块链来作为区块链架构。从而，实施例一提出同时基于区块链和智能合约来实现去中心化芯片研发交易模式。实施例一中，交易双方间的交易操作需以预先定好的智能合约为基础。
区块链技术可以通过分布式网络、时序不可篡改的密码学账本及分布式共识机制建立彼此的信任关系，利用智能合约来履行交易契约，通过去中心化的背书整合全球集成电路人才和产业资源。可见，对于去中心化芯片研发交易模式的实现，区块链是核心关键，可定制的自动强制执行的智能合约是执行保障和利益保障。
详细地，区块链技术可以通过密码学、点对点网络通信、共识算法、智能合约等多种技术的有效组合，构建数据存储、流转和处理的新型分布式计算架构，保障在不通过第三方中介机构信用背书条件下，实现数据的不易篡改、不易伪造、可追溯、可复核等目的。
详细地，智能合约是编程在区块链上的汇编语言。通常人们不会自己写字节 码，但是会从更高级的语言来编译它，例如用Solidity，与Javascript类似的专用语言。这些字节码可以给区块链的功能性提供了指引，因此代码可以很容易与它进行交互，例如转移密码学货币和记录事件。代码的执行是自动的，要么成功执行，或者所有的状态变化都撤消，甚至包括从当前失败的合约中已经发送或接收的信息，以避免出现合约部分执行的情况、对方不配合而无法逆转交易的情况等。
而在区块链环境中，由于智能合约的代码和状态都在区块链上，以使得所有人都可以看到智能合约，且智能合约不依赖某个特定的硬件设备，智能合约的代码可由所有参与共识的节点来执行。如此，从用户角度来讲，智能合约可被认为是一个自动担保账户，比如当特定的条件满足时，程序就会释放和转移资金。从技术角度来讲，基于架设在区块链上的智能合约，可以在区块链上运行特定的合约程序。
本实施例中，芯片需求企业可以快速地在平台上提出详细的开发和预算需求。其中，针对一个芯片研发交易目标，可以提出一个或多个芯片研发交易需求。芯片需求企业可以对应于区块链网络中的一交易节点，并由该交易节点在区块链网络中广播各个芯片研发交易需求。如此，各个其他交易节点均可接收到这一广播内容。在区块链网络中，可通过消息的广播来实现数据分享。
基于上述内容，交易节点可以为：具有共识权力的授权节点，不涉及区块构造过程但有区块读取权的普通节点，不涉及区块构造过程、没有区块读取权、具有交易权且能够读取与自身相关的交易信息的访客节点，中的任意一个。其中，授权节点可以包括从业单位节点和从业个人节点。
可见，访客节点、普通节点和授权节点均可以作为交易节点，以与其他交易节点间发生交易。其中，访客节点经授权可成为普通节点，普通节点经授权可成为授权节点，授权节点经授权可具有共识权而成为共识节点。平台的系统节点和具有共识权的授权节点即可组成共识节点集群。
本实施例中，可以由共识节点对两两交易节点间的交易进行实时监控。比如，在上述步骤102中，上述第一交易节点和上述第二交易节点间针对上述当前芯片研发交易需求而发生交易时，共识节点即可获取交易相关数据。获取到的数据主要用于进行链上和链下的分别存储，以记录这一交易相关数据。
两交易节点间发生交易时，交易节点会在区块链网络中广播这一交易信息，如此，共识节点即可实时获取每一次芯片研发交易的交易数据、智能合约消息数据和芯片研发数据。
详细地，交易数据可以为交易时间、交易双方信息等数据，数据量通常不大，可存储于区块链中。智能合约消息数据可以为，当前发生的交易在与智能合约相匹配时所产生的消息数据，比如当前次交易的时间符合智能合约中预先约定的时间这一数据，数据量通常不大，可存储于区块链中。芯片研发数据，可以包括研发出的阶段性产品，如设计图等，数据量通常较大，可存储于分布式链下存储系统中。
可见，本实施例中，数据层可以包括链上和链下两部分，其中链上部分可以是一个分布式区块链账本，是把区块串成链表的数据结构，链下部分可以是一个分布式存储系统。
详细地，区块链的基本技术特征就是，支持将一段时间内发生的交易整理成区块，区块间按照先后顺序以密码学方式链接起来，形成区块的链，该链在区块链网络参与节点间复制和共享，链上内容依据不同共识机制由参与节点组成的网络集体维护。通常情况下，区块链上的共识机制主要可以用来解决，由谁来构造区块以及如何维护区块链统一的问题。
本实施例中，对于区块链，交易是构成区块的主体内容，区块是区块链网络的数据组织单元，由链表来将区块进行串联，而哈希运算则是连接纽带。
本实施例中，对于链上部分，具体地，可以由共识节点将最近一段时间内的交易数据和智能合约消息数据打包成区块，新生成的区块按照发生的时间顺序链接到区块链上。将交易类似打包到区块中，变成不可篡改的交易，保证了交易的安全性，也就是对交易进行了确认。
实施例二
实施例二与实施例一基本相同，相同之处不再赘述，不同之处在于：该方法可以进一步包括：利用所述分布式链下存储系统，存储针对所述预设时间段内获取到的每一个芯片研发数据的目标哈希值；
所述步骤104，包括：生成新区块，其中，所述新区块的区块主体包括每一个 所述目标哈希值，以及所述预设时间段内获取到的所有交易数据和所有智能合约消息数据，所述新区块的区块头包括针对所述区块链中末位区块的哈希值、针对所述区块主体的哈希值和所述新区块生成时间的时间戳；基于所述时间戳，按照区块生成时间的先后顺序，将所述新区块链接到所述区块链上。
每一个区块都可以包括两部分，区块头和区块主体。其中，预设时间段内收集的交易数据和智能合约消息数据组成区块主体，区块主体中还可以包括该时间段内收集的各个芯片研发数据的目标哈希值。这一目标哈希值同样存在于分布式链下存储系统中，主要可作地址寻址之用，以方便可基于区块链而从分布式链下存储系统中快速查询到所需的芯片研发数据。
前一区块的哈希值可作为当前区块的头部信息。当前区块的头部信息还可以包括打包的那些交易数据和智能合约消息数据的哈希值。头部信息包括的时间戳可以用于区块间的排序。此外，在一种可能的实现方式中，头部信息还包括版本信息，与共识机制相关的信息等。对于与共识机制相关的信息，比如，可以为自主挖矿随机数、自主挖矿目标值或称挖矿难度。
实施例二中，可将芯片研发交易的交易数据及智能合约消息数据存储在区块链上管理，以达到可追溯防篡改的目的，可保证链的可靠运行、增强可监管性、提高区块的出块速度和稳定性。
本实施例中，对于链下部分，可将芯片研发交易涉及到的芯片研发数据作为链下数据存储到统一的分布式链下存储系统中。详细地，分布式链下存储系统可以包括云存储服务器，和/或，始终在线并稳定运行的系统节点。
详细地，对于云存储服务器来说，一个云存储服务器的节点将被用于存储非上链的业务数据。云存储服务器可以提供一个高吞吐量、内容寻址块存储模型以及内容寻址的超链接。平台中的资源、视频、文档等非结构化数据通过云存储服务器进行保存。用户的上传和下载操作经过应用服务器权限校验后，可以向云存储服务器进行操作请求。
实施例三
实施例三与实施例二基本相同，相同之处不再赘述，不同之处在于：该方法可以进一步包括：根据所述智能合约，在接收到一交易节点针对所述芯片研发交 易的任一芯片研发数据的获取请求时，向该交易节点反馈所述区块链上存储的所请求芯片研发数据的目标哈希值，以使该交易节点从所述分布式链下存储系统中获取反馈得到的目标哈希值对应的芯片研发数据。
详细地，芯片研发数据存储在链下存储服务器中时，为方便查询，链下存储服务器中同样会对应存储其哈希值，同上述目标哈希值，以作寻址地址之用。对应地，该目标哈希值会对应地存储在区块链中。以哈希算法为基础的文件地址，可为分布式的数据存储提供了最佳的安全保障。
详细地，当需要查询一芯片研发数据时，相应交易节点可广播这一数据查询请求，如此，共识节点即可根据智能合约，从区块链中找到该芯片研发数据的目标哈希值，以反馈给该交易节点。对应地，该交易节点即可根据反馈得到的哈希值，来获取到链下存储的该哈希值对应的芯片研发数据。
综上所述，本实施例可基于链上链下相结合的方式进行芯片研发交易数据的存储，以适用于存储较大数据量的芯片研发交易数据。
实施例四
实施例四与实施例一基本相同，相同之处不再赘述，不同之处在于：该方法可以进一步包括：接收每一个其他交易节点广播的针对所述当前芯片研发交易需求的竞标数据；确定广播目标竞标数据的所述第二交易节点中标，其中，所述目标竞标数据符合所述当前芯片研发交易需求的交易执行触发条件。
实施例四中，对于任一芯片研发交易需求来说，其他交易节点对应的芯片研发企业可自主竞标，并由中标的芯片研发企业负责该芯片研发交易需求的研发操作。中标的芯片研发企业所对应的交易节点即为上述第二交易节点。如此，本实施例中的交易节点，即可以为芯片研发交易需求方，也可以为芯片研发执行方。
详细地，芯片研发交易可以包括芯片的研发交易，也可以包括芯片的买卖交易等。交易发起方可以将自身的芯片研发交易目标在区块链网络中广播，以寻求交易接收方。
实施例五
实施例五与实施例四基本相同，相同之处不再赘述，不同之处在于：所述智能合约为实物交易合约、虚拟知识产权交易合约、授权合约、研发合约中的任意 一个；
所述实物交易合约包括：买方填写订单后进行费用支付；卖方确认收到费用支付的货款后进行实物发货；买方确认收到实物发货的货物后交易结束；
所述虚拟知识产权交易合约包括：买方经过内容预览并确认满意后进行费用支付；卖方确认收到费用支付的货款后，向买方提供下载地址和密钥；买方根据下载地址和密钥进行内容下载后交易结束；
所述授权合约包括：买方进行产品预览并确认满意后，签署保密协议；买方签署保密协议后进行产品试用；买方进行产品试用并确认满意后，签署产品授权合同并进行费用支付；卖方确认收到费用支付的货款后，授权买方进行使用；买方的产品授权使用到期后授权结束；
所述研发合约包括：雇主提出研发任务的各个研发产品的需求；雇员根据自身研发产品的需求设定研发方案及研发预算；雇主接受雇员的研发方案及研发预算后，雇员开展研发产品的开发；雇主确定开发出的研发产品满足需求后，向雇员支付研发费用；雇员确认收到研发费用后研发结束；
所述针对所述第一交易节点和所述第二交易节点执行相应交易操作，包括：在确定出所述第一交易节点和所述第二交易节点间发生的一交易，符合所述当前芯片研发交易需求的一达成交易触发条件时，基于所述区块链执行交易数据记录处理；在确定出所述第一交易节点和所述第二交易节点间发生的一交易，符合所述当前芯片研发交易需求的一解除交易触发条件时，基于所述区块链执行解除交易处理。
详细地，交易执行触发条件可以包括达成交易触发条件及接触交易触发条件。举例来说，当交易双方间的交易操作满足达成交易触发条件时，即可将生成的交易数据、智能合约消息数据等写入区块链，并执行智能合约中预设的达成交易时所需执行的交易操作，如转移交易资金等。当交易双方间的交易操作满足解除交易触发条件时，即可将生成的交易数据、智能合约交易数据写入区块链，并执行智能合约中预设的解除交易时所需执行的交易操作，如追偿已转移的交易资金等。
可见，智能合约作为一种链上代码，可以具有高效实时更新、准确执行、无人为干预、可分布式监督和仲裁、较低的运行成本等优点。基于智能合约将交易 双方直接联系在一起，而无中间商存在，从而避免高昂中介费用的存在。基于智能合约和区块链，可以保证所有交易和消息都得到应有的验证，保证交易的多样性、智能性、安全性和可扩展性，同时增强研发交易平台的可靠性、可监管性和稳定性。
由于芯片研发交易可以为研发交易、买卖交易等，如此，实施例五中的智能合约可以应用于多层次智能合约体系，以应对各种复杂的芯片研发交易和成品芯片的交易。
实施例六
如图2所示，以实施例一至实施例五为基础，实施例六提供了另一种去中心化芯片研发交易数据存储方法，以研发合约为例，可以包括以下步骤：
步骤201：对于交易节点集群中的任一交易节点，普通节点A广播有针对SoC(System on Chip，片上芯片系统)的3个芯片研发交易需求时，执行步骤202，其中，区块链上存储有针对SoC的研发合约，研发合约中记录有针对每一个芯片研发交易需求的交易执行触发条件。
例如，芯片研发交易需求方根据系统性能要求，通过研发合约提出3个芯片研发交易需求，即数字IP(Intellectual Property，知识产权)需求，模拟IP需求和射频IP需求。
详细地，研发合约里可以规定各个芯片研发交易需求最终需要达到的性能指标、接口标准、工艺参数等要求，以及交付的条件、形式、企业为开发每个芯片研发交易需求付出的报酬。
步骤202：针对每一个芯片研发交易需求均执行：共识节点C接收每一个其他交易节点广播的针对当前芯片研发交易需求的竞标数据。
需求发布以后，平台上所有用户，包括企业和个人，均可以以竞标的方式进行需求开发工作，最后只要提交的竞标数据满足研发合约的要求，都有机会在最终的竞标选择中胜出。
步骤203：共识节点C确定广播目标竞标数据的授权节点B中标，其中，研发合约目标竞标数据符合研发合约当前芯片研发交易需求的交易执行触发条件。
比如，研发合约中约定的交付形式可以是，满足性能指标要求前提下，最早 提交者胜出，那么系统提交时间最早的开发人员可中标，并将自动通过研发合约获得相应报酬。
再比如，以数字IP需求为例，研发合约中设定的数据IP需求的交易执行触发条件中，可以包括有竞标成功触发条件，如此，共识节点可以从所有竞标数据IP需求的竞标数据中，筛选出符合该竞标成功触发条件的每一个竞标数据，并基于预设排序规则对挑选出的竞标数据进行自动智能排序。如此，企业可以根据这一排序结果挑选出中标的竞标数据，并在区块链中广播中标结果。此后，共识节点即可根据数据IP需求的交易执行触发条件，对企业及中标者执行相应交易操作。比如，中标者的交易节点广播的最终产品符合预设的达成交易触发条件时，确定交易结束，并将相应交易信息数据写入区块链。
步骤204：共识节点C在确定出普通节点A和授权节点B之间发生的一芯片研发交易，符合一达成交易触发条件时基于区块链执行交易数据记录处理，或符合一解除交易触发条件时基于区块链执行解除交易处理，以获取针对芯片研发交易的交易数据、智能合约消息数据和芯片研发数据。
该共识节点C可以为所有共识节点中的任一共识节点。
详细地，交易双方的任一交易操作均可经预设智能合约的交易触发条件自动触发执行，对应交易数据以及智能合约消息数据写入区块链，无需再通过传统中心化的公司和组织来完成芯片的研发与交易。
步骤205：共识节点C利用分布式云存储服务器，存储预设时间段内获取到的所有芯片研发数据，以及针对预设时间段内获取到的每一个芯片研发数据的目标哈希值。
假设经所有共识节点共识后，由共识节点C具有记账权，故由共识节点C来生成新区块。详细地，共识节点C可以将需要链下存储的数据发送给分布式云存储服务器，以使其进行链下分布式存储。
步骤206：共识节点C生成新区块，其中，新区块的区块主体包括每一个目标哈希值，以及预设时间段内获取到的所有交易数据和所有智能合约消息数据，新区块的区块头包括针对区块链中末位区块的哈希值、针对区块主体的哈希值和新区块生成时间的时间戳。
步骤207：共识节点C基于时间戳，按照区块生成时间的先后顺序，将新区块链接到区块链上。
步骤208：共识节点D根据研发合约，在接收到普通节点E针对芯片研发交易的任一芯片研发数据的获取请求时，向普通节点E反馈区块链上存储的所请求芯片研发数据的目标哈希值。
假设研发合约中记录有，普通节点E具有针对该芯片研发交易的芯片研发数据的访问权，故任一共识节点，比如共识节点D在收到相应获取请求时，经研发合约，即可将其返回用于地址寻址的目标哈希值。
步骤209：普通节点E从分布式云存储服务器中获取反馈得到的目标哈希值对应的芯片研发数据。
