在步骤S3中，还包括以下步骤：
S301：接收由所述中转单元发到所述第二区块链的所述中转信息，并验证所述中转信息；
S302：对所述中转信息进行解封，并读取所述通信信息以及所述通信信息的处理方法；
S303：执行所述通信信息的处理方法，以及将所述通信信息发送到目标节点；
如附图2，为所述信息处理系统的一种实施形式的示意图，其中包括所述第一区块链101、所述中转单元102以及所述第二区块链103；在更多的实施形式中，一个所述处理系统可以包括多于两条区块链，本实施例仅为说明所述处理系统的一种实施方式；
其中，所述第一区块链101包括节点111、节点112以及节点113；所述第二区块链103包括节点131、节点132以及节点133；其中，所述节点113与节点133连接到所述中转单元102；所述中转单元102可以为一个云端的计算系统，或者一个分布式计算系统，或者是一个运行有联盟链的分布式系统，在此不作规定；
进一步的，所述第一区块链101以及所述第二区块链103包括使用外部程序接口，提供用户与区块链节点的连接通道，用于接收用户的信息处理需求，以及接收处理后的信息；当用户连接到所述第一区块链101的节点并进行信息发送时，用户使用应用程序通过所述外部程序接口提供所述通信信息；其中所述通信信息可以包括所述通信信息的处理方法；
进一步的，如附图3，在步骤S1中，所述通信信息在所述第一区块链101中的处理流程示意图；其中所述第一处理单元、所述第一封装单元以及所述第一通信单元可以为运行于所述第一区块链101应用层上的自动化应用程序，或者可以为运行于所述第一区块链101合约层上的智能合约程序；
当在所述第一区块链101上的用户A需要与所述第二区块链103的某用户B进行通证的交易，则所述通信信息301可以被处理为如附图4所示的格式：
所述通信信息301包括：
源，即发送节点在所述第一区块链101中的地址；
类型，即该通信信息待处理的服务的类型；
时间戳，即所述通信信息发出的时间；
数据，即待处理的通证的区块链地址；
进一步的，对所述通信信息301的处理方法包括，响应在所述第二区块链103上的智能合约，获取指定的交易地址信息等；
进一步的，在步骤S101中，处理所述通信信息301从而获得所述事件包302；对所述事件包302生成所述事件序列号，可以用于今后对所述事件包302的真实性和完整性进行验证，包括用于在所述中转单元以及所述第二验证单元的验证环节中；
在步骤S101中，可以包括使用发送节点的私钥对所述事件包302进行加密，从而防止所述事件包被非法读取；
所述事件序列号的生成方式，在其中一些实施例中，包括通过将所述事件包302的完整代码进行哈希函数计算后，获得一个固定长度的第一哈希码；任何节点或者区块链组织可以在获得一个所述事件包302后，采用相同的哈希函数对所述事件包302进行哈希运算得到的第二哈希码，通过将所述第二哈希码与所述第一哈希码作比较，从而确认被传达的所述事件包302是否前后完全一致；
如附图5，进一步的，在步骤S102中，所述第一封装单元处理所述事件包302，将目标节点所在的区块链的网络地址，在本实施例中即所述第二区块链103的网络地址；并且加入目标节点在所述第二区块链103中的节点地址；将所述事件包302、目标区块链的网络地址以及目标点节的节点地址封装，获得所述封装包303；
如附图6，进一步的，在步骤S103中，将多个所述封装包合并在一个所述通信包304内；其中，一个所述通信包内可以发送到多个目标区块链的所述封装包；
通过以上实施方式，将信息的内容以及处理方式、信息的接收方信息以及多个信息进行分层次处理，有效隔离了信息在处理过程的各个环节，提高了信息处理的效率和安全程度。
实施例二：
本实施例应当理解为至少包含前述任意一个实施例的全部特征，并在其基础上进一步改进；
在所述第一区块链，由所述中转单元维护有若干个中转节点；所述第一区块链上的普通节点用于所述第一区块链上的一般信息记录；而由所述中转节点维护的所述中转节点，则用于记录所述中转节点已经完成中转的所述中转信息，以确认所述通信信息的处理和发送已经按照用户的需求进行处理；
其中，由于区块链的技术的原理，决定了区块链存在分叉的情况；区块链的分叉是指当由区块链内的共识机制发生改变时，与原生协议不相容时，部分反对新协议的节点遵循原有旧协议的共识，从而无法达成新协议的区块账本；然后各方各自延续自己认为正确的区块链，所以分成了两条链；该情况包括良性的区块链分叉，例如区块链的发起组织发布新的共识机制协议，由于非中心化的要求，节点进行选择是否执行新协议；或者，是区块链受到攻击，由攻击者发起了恶性分叉，从而窜改区块链以往数据并由此生成新的数据的区块；尤其对于维护节点较少的区块链，发生算力攻击的概率比较大，容错率也较低；因此本实施例包括优化所述中转节点生成所述中转信息的流程，其中包括对所述第一区块链的区块高度的验证；
由于区块的生成是按照特定时间周期性地生成新的区块，然而因为需要对区块数据进行共识认证，所以如附图6所示，在新的区块A生成后，并不是等待区块A被区块链完全确认完毕才生成后面的区块B、区块C……，而是在生成区块A的特定时间后即马上生成区块B；区块B的区块头内记录所述区块A的哈希信息；待区块A完成全链共识认证后，再去对区块B进行全链共识认证；
因此，如附图7若在区块B中发生分叉，后续生成了包括区块C和区块D所在的旧链，以及包括区块C´和区块D´的新链；后续的区块的生成则需要验证区块B中的区块账本数据，并以此决定跟随旧链或者新链；
因此提出在步骤S2中，所述中转单元需要确认当前待生成的所述中转区块的高度X，是否大于保存所述通信信息的区块高度Y；
若所述中转区块的高度X小于高度Y，即保存所述通信信息的区块保存于所述这，则所述中转单元需要验证所有从高度X+1到高度Y的所有区块的所述第一区块链的默克尔树信息，以确认区块从高度X+1到高度Y之间的所有区块已通过所述第一区块链上的所有节点的共识验证，并确认区块高度为Y的区块是否在最长链上；若区块高度为Y的区块为最长链上，则在区块高度为X的所述中转区块中生成所述中转信息；
若中转区块的高度X大于所述高度Y，则基于所述第一区块链的默克尔树信息，在所述中转区块生成所述中转信息；
使用以上验证方式，保证所述中转信息所传达的所述通信信息都通过所述第一区块链的共识认证，避免了由于分叉所造成的，传达了被窜改或者无法通过共识认证的通信信息。
实施例三：
本实施例应当理解为至少包含前述任意一个实施例的全部特征，并在其基础上进一步改进；
所述中转信息是根据目标区块链的网络地址从而生成的，因此同一个所述中转信息内包含的多个所述封装包都具有同一个区块链网络地址，而可能具有多个不同的节点地址；
因此，进一步的，在所述步骤S301中，所述第二验证单元包括验证所述中转信息是否由所述中转单元通过了步骤S2的区块验证过程；
进一步的，所述第二验证单元还包括验证所述中转信息中的所有目标节点地址是否均为所述第二区块链的节点地址；
进一步的，所述第二验证单元还包括向所述中转单元反馈验证过程中没有通过验证的部分，例如，具有错误目标节点地址的所述封装包；
在所述第二验证单元通过对所述中转信息的验证后，将所述中转信息提交到所述第二封装单元进行解封并读取内部多个所述封装包303所包含的所述事件包302内容；
所述第二处理单元执行根据多个所述事件包302的内容，执行所述通信信息301的处理方法，以及将所述通信信息301发送到目标节点。
在上述实施例中，对各个实施例的描述都各有侧重，某个实施例中没有详述或记载的部分，可以参见其它实施例的相关描述。
虽然上面已经参考各种实施例描述了本发明，但是应当理解，在不脱离本发明的范围的情况下，可以进行许多改变和修改。也就是说上面讨论的方法，系统和设备是示例。各种配置可以适当地省略，替换或添加各种过程或组件。例如，在替代配置中，可以以与所描述的顺序不同的顺序执行方法，和/或可以添加，省略和/或组合各种部件。而且，关于某些配置描述的特征可以以各种其他配置组合，如可以以类似的方式组合配置的不同方面和元素。此外，随着技术发展其中的元素可以更新，即许多元素是示例，并不限制本公开或权利要求的范围。
在说明书中给出了具体细节以提供对包括实现的示例性配置的透彻理解。然而，可以在没有这些具体细节的情况下实践配置例如，已经示出了众所周知的电路，过程，算法，结构和技术而没有不必要的细节，以避免模糊配置。该描述仅提供示例配置，并且不限制权利要求的范围，适用性或配置。相反，前面对配置的描述将为本领域技术人员提供用于实现所描述的技术的使能描述。在不脱离本公开的精神或范围的情况下，可以对元件的功能和布置进行各种改变。
综上，其旨在上述详细描述被认为是例示性的而非限制性的，并且应当理解，以上这些实施例应理解为仅用于说明本发明而不用于限制本发明的保护范围。在阅读了本发明的记载的内容之后，技术人员可以对本发明作各种改动或修改，这些等效变化和修饰同样落入本发明权利要求所限定的范围。
