具体实施方式
这里将详细地对示例性实施例进行说明，其示例表示在附图中。下面的描述涉及附图时，除非另有表示，不同附图中的相同数字表示相同或相似的要素。以下示例性实施例中所描述的实施方式并不代表与本说明书一个或多个实施例相一致的所有实施方式。相反，它们仅是与如所附权利要求书中所详述的、本说明书一个或多个实施例的一些方面相一致的装置和方法的例子。
需要说明的是：在其他实施例中并不一定按照本说明书示出和描述的顺序来执行相应方法的步骤。在一些其他实施例中，其方法所包括的步骤可以比本说明书所描述的更多或更少。此外，本说明书中所描述的单个步骤，在其他实施例中可能被分解为多个步骤进行描述；而本说明书中所描述的多个步骤，在其他实施例中也可能被合并为单个步骤进行描述。
图1是一示例性实施例提供的一种示例环境的示意图。如图1所示，示例环境100允许实体参与区块链网络102。区块链网络102可以为公有类型、私有类型或联盟类型的区块链网络。示例环境100可以包括计算设备104、106、108、110、112和网络114；在一实施例中，网络114可以包括局域网(Local Area Network，LAN)、广域网(Wide Area Network，WAN)、因特网或其组合，并连接至网站、用户设备(例如计算设备) 和后端系统。在一实施例中，可以通过有线和/或无线通信方式访问网络114。
在某些情况下，计算设备106、108可以是云计算系统的节点(未显示)，或者每个计算设备106、108可以是单独的云计算系统，包括由网络互连并作为分布式处理系统工作的多台计算机。
在一实施例中，计算设备104～108可以运行任何适当的计算系统，使其能够作为区块链网络102中的节点；例如，计算设备104～108可以包括但不限于服务器、台式计算机、笔记本电脑、平板电脑计算设备和智能手机。在一实施例中，计算设备104～108可以归属于相关实体并用于实现相应的服务，例如该服务可以用于对某一实体或多个实体之间的交易进行管理。
在一实施例中，计算设备104～108分别存储有区块链网络102对应的区块链账本。计算设备104可以是(或包含)用于提供浏览器功能的网络服务器，该网络服务器可基于网络114提供与区块链网络102相关的可视化信息。在一些情况下，计算设备104可以不参与区块验证，而是监控区块链网络102以确定其他节点(譬如可以包括计算设备106-108)何时达成共识，并据此生成相应的区块链可视化用户界面。
在一实施例中，计算设备104可接收客户端设备(例如计算设备110或计算设备112)针对区块链可视化用户界面发起的请求。在一些情况下，区块链网络102的节点也可以作为客户端设备，比如计算设备108的用户可以使用运行在计算设备108上的浏览器向计算设备104发送上述请求。
响应于上述请求，计算设备104可以基于存储的区块链账本生成区块链可视化用户界面(如网页)，并将生成的区块链可视化用户界面发送给请求的客户端设备。如果区块链网络102是私有类型或联盟类型的区块链网络，对区块链可视化用户界面的请求可以包括用户授权信息，在生成区块链可视化用户界面并发送给请求的客户端设备之前，可以由计算设备104对该用户授权信息进行验证，并在验证通过后返回相应的区块链可视化用户界面。
区块链可视化用户界面可以显示在客户端设备上(例如可显示在图1所示的用户界面116中)。当区块链账本发生更新时，用户界面116的显示内容也可以随之发生更新。此外，用户与用户界面116的交互可能导致对其他用户界面的请求，例如显示区块列表、区块详情、交易列表、交易详情、账户列表、账户详情、合约列表、合约详情或者用户对区块链网络实施搜索而产生的搜索结果页面等。
图2是一示例性实施例提供的一种概念架构的示意图。如图2所示，该概念架构200包括实体层202、托管服务层204和区块链网络层206。例如，实体层202可以包括三个实体：实体1、实体2和实体3，每个实体都有各自的交易管理系统208。
在一实施例中，托管服务层204可以包括每个事务管理系统208对应的接口210。例如，各个事务管理系统208使用协议(例如超文本传输协议安全(HTTPS)等)通过网络(例如图1中的网络114)与各自的接口210通信。在一些例子中，每个接口210可以提供各自对应的交易管理系统208与区块链网络层206之间的通信连接；更具体地，接口210可与区块链网络层206的区块链网络212通信。在一些例子中，接口210和区块链网络层206之间的通信可以使用远程过程调用(Remote Procedure Calls，RPCs)而实现。在一些例子中，接口210可以向交易管理系统208提供用于访问区块链网络212的API接口。
如本文所述，区块链网络212以对等网络的形式提供，该对等网络包括多个节点214，这些节点214分别用于对块链数据所形成的区块链账本216进行持久化；其中，图2中仅示出了一份区块链账本216，但区块链网络212中可以存在多份区块链账本216或其副本，比如每一节点214可以分别维护一份区块链账本216或其副本。
需要指出的是：在本说明书中所描述的交易(transaction)，是指用户通过区块链的客户端创建，并需要最终发布至区块链的分布式数据库中的一笔数据。其中，区块链中的交易，存在狭义的交易以及广义的交易之分。狭义的交易是指用户向区块链发布的一笔价值转移；例如，在传统的比特币区块链网络中，交易可以是用户在区块链中发起的一笔转账。而广义的交易是指用户向区块链发布的一笔具有业务意图的业务数据；例如，运营方可以基于实际的业务需求搭建一个联盟链，依托于联盟链部署一些与价值转移无关的其它类型的在线业务(比如，租房业务、车辆调度业务、保险理赔业务、信用服务、医疗服务等)，而在这类联盟链中，交易可以是用户在联盟链中发布的一笔具有业务意图的业务消息或者业务请求。
图3是一示例性实施例提供的一种跨链用权方法的流程图。如图3所示，该方法应用于跨链中继，所述跨链中继分别连接至少一条存证区块链、至少一条用权区块链；所述方法可以包括以下步骤：
步骤302，接收用权区块链针对权利应用业务发起的确权请求。
在一实施例中，跨链中继用于在用权区块链与存证区块链之间实现中继功能，使得 用权区块链能够通过该跨链中继对存证区块链进行访问，从而实现了用权区块链与存证区块链之间的对接。同时，基于跨链中继所实现的中继功能，使得用权区块链、存证区块链分别与跨链中继对接，而并非由用权区块链与存证区块链之间直接对接，可以根据实际需求对接入跨链中继的用权区块链、存证区块链进行增加或减少，因而整个系统具有极佳的可扩展性。
在一实施例中，当用权区块链向跨链中继发起确权请求时，具体应当为该用权区块链上的至少一个区块链节点向跨链中继发起该确权请求。例如，区块链客户端可以基于用户指示而向用权区块链上的至少一个区块链节点发送请求指令，使得该至少一个区块链节点可以向跨链中继发起相应的确权请求；再例如，区块链客户端可以向用权区块链上的至少一个区块链节点提交一笔交易提案，使得该交易提案在通过共识并被执行时，可以向跨链中继发起上述的确权请求；又例如，区块链客户端可以向用权区块链上的至少一个区块链节点提交一笔交易提案，使得该交易提案在通过共识并被执行时，可以调用智能合约，该智能合约可用于自动向跨链中继发起上述的确权请求，且该智能合约可以进一步根据存证区块链反馈的权利归属数据而确定是否执行相关操作，比如在权利归属数据表明目标权利归属于目标对象时，才允许相关操作顺利执行，否则终止相关操作。
步骤304，读取存证区块链上存证的权利归属数据。
在一实施例中，存证区块链用于对权利归属数据进行存证，该权利归属数据用于记录相关权利的归属情况；以图书版权为例，可以记录图书版权与所有者之间的映射关系，比如某一用户A拥有图书B的版权、某一企业C拥有图书D的版权等。由于存证区块链采用分布式数据库技术，即若干区块链节点共同维护统一的区块链账本，并且区块链账本所含的区块之间实现为具有内容相关性的块链结构，使得存证区块链的区块链账本具有公开、不可篡改的特性，以便于实现安全可靠的存证功能。
在一实施例中，除了上述的图书版权之外，本说明书中的权利还可以包含其他类型，比如歌曲版权、电影版权、软件著作权、专利权、不动产权等，本说明书并不对此进行限制。
步骤306，根据所述权利归属数据对所述确权请求进行响应，以使所述用权区块链根据响应结果对所述权利应用业务进行处理。
在一实施例中，跨链中继可以根据所述权利归属数据，判断所述确权请求中指示的目标权利是否归属于目标对象，并将判断结果返回所述用权区块链。换言之，用权区块 链接收到的响应结果包含上述的判断结果，使得用权区块链可以据此对权利应用业务进行处理。
在一实施例中，跨链中继可以获取所述权利归属数据，并将所述权利归属数据返回所述用权区块链，以由所述用权区块链判定目标权利是否归属于目标对象。换言之，用权区块链可以获得权利归属数据，使得该用权区块链上的区块链节点可以基于该权利归属数据确定目标权利是否归属于目标对象，而跨链中继仅用于获取权利归属数据并提供至用权区块链。
相应的，图4是一示例性实施例提供的另一种跨链用权方法的流程图。如图4所示，该方法应用于用权区块链上的区块链节点，所述用权区块链连接至跨链中继，所述跨链中继还连接至少一条存证区块链；所述方法可以包括以下步骤：
步骤402，针对权利应用业务向所述跨链中继发起确权请求，以使所述跨链中继读取存证区块链上存证的权利归属数据并根据所述权利归属数据对所述确权请求进行响应。
在一实施例中，跨链中继用于在用权区块链与存证区块链之间实现中继功能，使得用权区块链能够通过该跨链中继对存证区块链进行访问，从而实现了用权区块链与存证区块链之间的对接。同时，基于跨链中继所实现的中继功能，使得用权区块链、存证区块链分别与跨链中继对接，而并非由用权区块链与存证区块链之间直接对接，可以根据实际需求对接入跨链中继的用权区块链、存证区块链进行增加或减少，因而整个系统具有极佳的可扩展性。
在一实施例中，当用权区块链向跨链中继发起确权请求时，具体应当为该用权区块链上的至少一个区块链节点向跨链中继发起该确权请求。例如，区块链客户端可以基于用户指示而向用权区块链上的至少一个区块链节点发送请求指令，使得该至少一个区块链节点可以向跨链中继发起相应的确权请求；再例如，区块链客户端可以向用权区块链上的至少一个区块链节点提交一笔交易提案，使得该交易提案在通过共识并被执行时，可以向跨链中继发起上述的确权请求；又例如，区块链客户端可以向用权区块链上的至少一个区块链节点提交一笔交易提案，使得该交易提案在通过共识并被执行时，可以调用智能合约，该智能合约可用于自动向跨链中继发起上述的确权请求，且该智能合约可以进一步根据存证区块链反馈的权利归属数据而确定是否执行相关操作，比如在权利归属数据表明目标权利归属于目标对象时，才允许相关操作顺利执行，否则终止相关操作。
在一实施例中，存证区块链用于对权利归属数据进行存证，该权利归属数据用于记录相关权利的归属情况；以图书版权为例，可以记录图书版权与所有者之间的映射关系，比如某一用户A拥有图书B的版权、某一企业C拥有图书D的版权等。由于存证区块链采用分布式数据库技术，即若干区块链节点共同维护统一的区块链账本，并且区块链账本所含的区块之间实现为具有内容相关性的块链结构，使得存证区块链的区块链账本具有公开、不可篡改的特性，以便于实现安全可靠的存证功能。
在一实施例中，除了上述的图书版权之外，本说明书中的权利还可以包含其他类型，比如歌曲版权、电影版权、软件著作权、专利权、不动产权等，本说明书并不对此进行限制。
步骤404，根据所述跨链中继返回的响应结果，对所述权利应用业务进行处理。
在一实施例中，跨链中继可以根据所述权利归属数据，判断所述确权请求中指示的目标权利是否归属于目标对象，并将判断结果返回所述用权区块链。换言之，用权区块链接收到的响应结果包含上述的判断结果，使得用权区块链可以据此对权利应用业务进行处理。
在一实施例中，跨链中继可以获取所述权利归属数据，并将所述权利归属数据返回所述用权区块链，以由所述用权区块链判定目标权利是否归属于目标对象。换言之，用权区块链可以获得权利归属数据，使得该用权区块链上的区块链节点可以基于该权利归属数据确定目标权利是否归属于目标对象，而跨链中继仅用于获取权利归属数据并提供至用权区块链。
在一实施例中，用权区块链上的区块链节点可以根据所述响应结果生成确权信息，所述确权信息表明目标权利归属于目标对象；然后，该区块链节点可以向所述用权区块链提交对应于所述权利应用业务的区块链交易，所述区块链交易中包含所述确权信息。例如，未包含确权信息的区块链交易将无法通过共识；再例如，通过在区块链交易中包含确权信息，使得该确权信息被作为该区块链交易能够成功执行的先决条件之一；又例如，通过在区块链交易中包含确权信息，可以作为该区块链交易的有效性证明之一，而未包含确权信息的区块链交易将被确定为无效交易。
在一实施例中，用权区块链的区块链节点可以向该用权区块链提交对应于所述权利应用业务的区块链交易，所述区块链交易包含对智能合约的调用信息，以通过所述智能合约执行所述区块链交易；相应地，该区块链节点可以通过调用所述智能合约，向所述 跨链中继发起所述确权请求；以及，该区块链节点可以向所述智能合约提供所述响应结果，以由所述智能合约根据所述响应结果执行所述区块链交易，比如智能合约可以在响应结果表明目标权利归属于目标对象时执行区块链交易所指示的交易操作，否则避免执行该交易操作。
需要说明的是：在本说明书中所描述的交易(transaction)，是指用户通过区块链的客户端创建，并需要最终发布至区块链的分布式数据库中的一笔数据。其中，区块链中的交易，存在狭义的交易以及广义的交易之分。狭义的交易是指用户向区块链发布的一笔价值转移；例如，在传统的比特币区块链网络中，交易可以是用户在区块链中发起的一笔转账。而广义的交易是指用户向区块链发布的一笔具有业务意图的业务数据；例如，运营方可以基于实际的业务需求搭建一个联盟链，依托于联盟链部署一些与价值转移无关的其它类型的在线业务(比如，版权业务、租房业务、车辆调度业务、保险理赔业务、信用服务、医疗服务等)，而在这类联盟链中，交易可以是用户在联盟链中发布的一笔具有业务意图的业务消息或者业务请求。
为了便于理解，下面以图书版权的用权场景为例，结合图5对本说明书的技术方案进行详细说明。
图5是一示例性实施例提供的一种跨链用权系统的示意结构图。如图5所示，该系统可以包括：一条或多条存证区块链、一条或多条用权区块链和至少一个跨链中继，例如存证区块链可以包括区块链511、512、513和514，用权区块链可以包括区块链531、532和533，跨链中继可以包括中继521、522。
区块链511～514用于对权利归属数据进行存证；在图书版权的场景中，权利归属数据用于表明图书版权的归属情况，比如某一图书版权T1归属于用户UA、另一图书版权T2归属于企业UB等，这些权利归属数据可能由于隐私要求(譬如不同区块链用于存证不同隐私需求级别的权利归属数据)、业务隔离(譬如个人业务与公司业务、教育类图书业务与科技类图书业务等)、参与方联盟(譬如不同联盟分别采用不同的存证区块链，每一存证区块链仅存储相应联盟的参与方所提供的权利归属数据)等原因而分别存证于不同的存证区块链。区块链511～514上的区块链节点可以分别对被提交的版权数据进行共识，并将通过共识的版权数据以诸如键值对(key-value)或本说明书并不限制的其他任意形式保存为相应的权利归属数据，使得权利归属数据被记录于相应区块链的区块链账本中，从而对权利归属数据进行存证。因此，当跨链中继521或522从区块链511～514的区块链账本中读取权利归属数据时，可以确保该权利归属数据所描述的图书 版权的归属情况真实有效，使得用权区块链可以据此处理相关权利应用业务。
如上文所述，跨链中继521-522用于实现区块链511～514与区块链531～533之间的数据连接，使得区块链531～533可以经由跨链中继521-522对区块链511～514所存证的权利归属数据进行访问，以用于确定对相关权利应用业务的处理方式。而作为用权区块链的区块链531～533等，用于根据实际业务需求而通过跨链中继521-522对区块链511～514所存证的权利归属数据进行访问。其中，取决于隐私需求、业务需求、参与方隔离需求等原因，使得用权区块链的数量可以为如图5所示的多个(如区块链531～533)，当然本说明书并不对此进行限制。
举例而言，假定企业UX与用户UA约定：由企业UX向用户UA支付一定的资产凭证，以获得对用户UA绘制的画作K的图书版权的使用授权。譬如企业UX侧的工作人员可以对计算设备540进行操作，使得该计算设备540可以向区块链532中的区块链节点532a提交一笔交易提案，该交易提案针对用户UA所持有的画作K而发起，用于在确定用户UA拥有画作K的图书版权后，向用户UA支付数额为i的资产凭证。
区块链节点532a可以在区块链532中发布该交易提案，使得该交易提案在区块链532中得以执行。由于交易提案需要完成2步操作：第一步用于验证用户UA拥有画作K的图书版权，第二步用于由企业UX向用户UA支付数额为i的资产凭证，那么可以预先定义一智能合约并使得该交易提案对该智能合约进行调用，使得该智能合约可以自动高效、不受外界影响地完成上述2步操作。
例如，智能合约可以向跨链中继521或522发起确权请求，该确权请求用于请求验证用户UA是否拥有画作K的图书版权。如果智能合约将确权请求发送至跨链中继521，那么跨链中继521可以根据相关技术中的跨链技术(如侧链技术、公证人技术等，本说明书并不对此进行限制)，读取区块链511～514所存证的权利归属数据，从而根据该权利归属数据来验证用户UA是否拥有画作K的图书版权。其中，当画作K的图书版权的归属情况被记录于区块链511或512的区块链账本时，由于图5中的跨链中继521与区块链511-512直接连接，因而跨链中继521可以直接读取区块链511-512存证的权利归属数据、验证用户UA是否拥有画作K的图书版权；当画作K的图书版权的归属情况被记录于区块链513或514的区块链账本时，由于图5中的跨链中继521并未与区块链513-514直接连接，因而跨链中继521可以通过与跨链中继522之间的数据通道，读取区块链513-514存证的权利归属数据，以验证用户UA是否拥有画作K的图书版权，当然也可以由跨链中继522验证用户UA是否拥有画作K的图书版权并将验证结果告知 跨链中继521。
无论是读取权利归属数据并据此验证用户UA是否拥有画作K的图书版权，或者直接获得跨链中继522返回的验证结果，总之跨链中继521可以获得相应的验证结果，并向上述的智能合约返回相应的验证结果。相应的，智能合约可以在验证结果表明用户UA拥有画作K的图书版权时，完成上述的第二步操作，即由企业UX向用户UA支付数额为i的资产凭证，譬如使得企业UX对应的区块链账户减少数额为i的资产凭证、使得用户UA对应的区块链账户增加数额为i的资产凭证。当然，如果验证结果表明用户UA未拥有画作K的图书版权，智能合约可以拒绝执行上述的第二步操作，比如可以判定该第二步操作执行失败。
可见，由于采用如图5所示“存证区块链-跨链中继-用权区块链”的系统结构，使得存证区块链、用权区块链仅需分别考虑与跨链中继之间的连接，而无需考虑存证区块链与用权区块链之间的直接对接，因而当存证区块链或用权区块链需要发生增减变化时，能够便捷地实施相应的配置操作，使得系统具有极大的可扩展性。
