Referring to FIG. 1, FIG. 1 is a schematic diagram of parallel link cross-link interactions using a link card and a cross-link platform. In fig. 1, each parallel chain 1 establishes connection with a cross-chain platform 3 through a chain card 2, so as to realize cross-chain functions such as data storage, data sharing, asset transfer and the like. The parallel chain 1 reports basic information to the cross-chain platform 3, and after receiving the basic information of the parallel chain 1, the cross-chain platform 3 sends a chain card corresponding to the basic information to the parallel chain 1 for installation.
In some embodiments, because different parallel chains may have different chain architectures, the cross-chain platform needs to send and install with the corresponding chain cards. For example, some parallel chains are suitable for IOS systems and some parallel chains are suitable for android systems. So that different types of chain cards can be provided according to different development languages. The data in the chain card sent to the parallel chain by the cross-chain platform is encrypted based on the public key of the cross-chain platform, the data is in Json format, and the parallel chain is installed after obtaining the decryption of the data in the chain card by the private key. By setting the data in the chain card to be in the Json format, the chain card is suitable for platforms of many different architectures after packaging, and has high universality. And by using asymmetric encryption algorithms, privacy of the cross-chain transaction can be ensured. Meanwhile, the cross-chain platform 3 supports an external supervision organization to set nodes to realize cross-chain operation supervision. The cross-chain platform 3 is used to implement cross-chain operations between multiple co/heterogeneous parallel chains. The cross-chain platform comprises: an application layer, cross-chain middleware, and an infrastructure layer. Wherein the application layer includes basic functions and cross-chain functions. The cross-chain functions include account cross-chain, data cross-chain, and asset cross-chain. The cross-chain middleware comprises functions of a chain card, transaction management, a message mechanism, privacy protection and the like. The chain card comprises a client installation package, a communication protocol, an encryption and decryption mechanism, cross-chain contract deployment, a main data standard, an interface using method and a permission authentication and monitoring mechanism. The infrastructure layer is mainly a cloud service and blockchain platform supporting cross-chain operation. A cross-chain intelligence contract is deployed in the blockchain platform. The cross-chain intelligent contracts include cross-chain rights authentication, cross-chain transaction monitoring, cross-chain transaction billing, cross-chain sharing applications, cross-chain message distribution, asset cross-chain processing and cross-chain message rollback mechanisms. Thus, the cross-chain platform provides better security and privacy when implementing multi-parallel chain cross-chain. When the chain card realizes data interaction between the parallel chains and the cross-chain platform, an asymmetric encryption algorithm is used, so that the privacy of the cross-chain transaction can be ensured. Meanwhile, each parallel chain can inquire the required data, and the cross-chain authority can be obtained in an application mode, so that the safety and the effectiveness of the cross-chain among the parallel chains can be ensured.
In some embodiments, preset contracts are installed in each of the parallel chains 1 and the cross-chain platform 3. Therefore, by installing the preset contracts, not only can the data among different blockchains be converted and shared, but also the data safety in the data cross-chain transmission can be ensured, thereby realizing the cross-chain functions of data storage, data sharing, asset transfer and the like.
In some embodiments, cross-chain rights authentication is used to issue identity credentials for parallel chains that pass identity authentication. And if the parallel chain is detected to have the identity certificate, determining that the parallel chain has the cross-chain authority. In the event that no identity certificate is detected for a parallel chain, then it is determined that the parallel chain does not have cross-chain rights. Cross-chain transaction monitoring is used to monitor and acquire all transaction cases related to cross-chains using chain cards. The cross-chain transaction accounting is used to account for both cross-chain transaction parties and cross-chain content. The cross-chain sharing application is used for aiming at parallel chains with data requirements, and a requirement party initiates an application to a provider by calling a cross-chain sharing application function so as to obtain the data provided by the provider. Cross-chain message distribution is used to lock, map, generate processes, etc., digital assets in the event that parallel chains initiate asset cross-chain operations. The cross-chain transaction rollback mechanism is used for triggering the cross-chain transaction rollback mechanism to roll back to the last cross-chain transaction node and account for when the parallel chain does not respond to the cross-chain transaction for a long time and the accounting action does not occur, until the cross-chain transaction publisher is rolled back to complete the closed loop of the cross-chain failure.
In some embodiments, the chain card implements cross-chain operations between parallel chains by providing the communication protocols, communication encryption and decryption mechanisms, cross-chain listening mechanisms, cross-chain master data standards, cross-link port calls, multi-language cross-chain intelligent contracts, and identity authentication required for the cross-chains.
In some embodiments, the architecture of the chain card includes basic services, cross-chain execution, and cross-chain applications.
In some embodiments, the base services include a cross-chain authentication mechanism module, a cross-chain communication setup module, an interface call module, a data compatibility module, an identity authentication module, a contract provision module, a privacy protection module, a communication security module, and a log service module.
The cross-chain verification mechanism module is used for verifying whether a cross-chain exists or not and verifying whether the cross-chain is valid or not. The cross-link communication establishment module is used for providing a communication protocol and performing communication encryption/decryption. Therefore, the security of data cross-link can be improved by carrying out communication encryption/decryption when the cross-link connection is established, and the privacy of users and the security of data transmission are protected. The interface calling module is used for calling the certificate storage interface and the unified data cross-chain interface. The data compatible module is used for providing a main data standard and performing data analysis by using a unified data analysis mode. Therefore, the problem that the cross-link transaction data is difficult to be compatible due to the difference of data uplink structures and the difference of data analysis methods caused by different structures can be avoided by unifying the data cross-link ports and the data analysis modes. The identity authentication module is used for carrying out account authentication and authority authentication. Thus, identity authentication, privacy protection, communication security and the like are performed, so that the same/different block chains can be ensured to conveniently realize the cross-chain operation in a safe environment. The contract providing module is used for carrying out authority authentication, transaction monitoring, cross-chain sharing, cross-chain certificate storage, asset processing, message distribution or transaction rollback and the like.
In some embodiments, the cross-chain execution includes a cross-chain transaction management module and a security mechanism module. The cross-chain transaction management module is used for performing cross-chain transaction monitoring, cross-chain transaction acquisition, cross-chain transaction checking, cross-chain transaction analysis, providing cross-chain transaction routing and acquiring cross-chain transaction logs. The security mechanism module is used for performing key management, transaction signature, privacy protection or security rollback and the like.
In some embodiments, the cross-chain application includes cross-chain transaction application, cross-chain transaction audit, cross-chain sharing management or cross-chain state management, and the like. In this way, the chain card module can provide cross-chain communication, cross-chain business operation, cross-chain rules and the like between the parallel chains and the cross-chain Hub platform. Because the chain card contains unified cross-chain communication protocols, main data standards, interface usage patterns and the like. After both sides of the cross-link requirement complete the installation of the link card, the link card can serve as a connecting medium for both sides to realize the monitoring and acquisition of the cross-link event. The two sides of the cross-link can support all types of cross-link scenes without paying excessive attention to the structure and the consensus characteristic of the cross-link and completing the pre-deployment of the cross-link according to the requirements of the chain card device. The chain card can open the data interaction channel and the technical support among the parallel chains, thereby realizing application scenes such as data storage, data sharing, asset circulation and the like.
