All other embodiments that can be made by one skilled in the art based on the embodiments in the present application in light of the present disclosure are within the scope of the present application.

The terms "first," "second," "third," "fourth," and the like in the description and in the claims of the present application and in the above-described drawings (if any) are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the application described herein are capable of operation in sequences other than those illustrated or described herein. Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.

The terms referred to in this application are explained first:

block chains: the blockchain is a distributed ledger, distributed over computer nodes, that records all transactions that occur over the network. The uplink refers to recording information needing uplink, such as transfer records, orders, data distribution tables and the like, on a block. The blocks are one storage unit, and all communication information of each block node within a certain time is recorded. The blocks are linked through random hashing (also called hashing algorithm), the next block contains the hash value of the previous block, one block is connected with one block successively along with the expansion of information exchange, and the formed result is called a block chain.

A block chain as a Service (BaaS) platform: the method is a block chain open platform which is used for embedding a block chain frame into a cloud computing platform, providing a convenient and high-performance block chain ecological environment and ecological matching service for developers by using the deployment and management advantages of cloud service infrastructure, and supporting the business expansion and operation support of the developers. The BaaS platform packages the block chain technology combination, and modularizes the block chain technology combination into the functions of common host management, block chain network management, channel management, intelligent contracts, block chain browser management, block chain monitoring, certificate management, user management and the like, when a user needs to perform uplink storage and query on a block chain, the functions are connected only through interfaces such as an Application Programming Interface (API) and a Software Development Kit (SDK), and the like, so that the block chain BaaS platform can be directly used for performing intelligent contract uplink storage and query.

Virtualizing the BaaS platform: and performing virtualization management on the Baas platforms of various alliance chains and chain virtualization management based on software definition, and finally providing a platform for unifying external service capability.

The terminal equipment: refers to an apparatus that inputs programs and data to a computer or receives a result of processing by the computer via a communication facility. The terminal equipment is usually set in a convenient place where it can be connected with remote computer by means of communication equipment, and is mainly formed from communication interface control device and special-purpose or selected input and output device. The terminal device includes, but is not limited to, means for communicating via a data connection/Network and/or via a Wireless interface, such as a communication means for a cellular Network, a Wireless Local Area Network (WLAN). The terminal device has sending, receiving and inputting functions, is provided with a display, can be a desktop computer or other intelligent terminals such as a notebook computer, and the embodiment of the application does not limit the specific form of the terminal device and can be determined according to actual requirements.

The blockchains are mainly divided into public, federation, and private chains. There are, among others, a number of heterogeneous types of federation chains in the prior art. And for each alliance chain, a corresponding BaaS platform is arranged, and a user can carry out intelligent contract chain storage and inquiry on the alliance chain through the corresponding BaaS platform. That is, a user can only use a certain type of federation chain according to the usage rule of the federation chain, and perform intelligent contract uploading and certification and query on the federation chain through the BaaS platform corresponding to the federation chain. When a user needs to use another type of alliance chain, the corresponding BaaS platform needs to be replaced, and the usage rules of each type of alliance chain are different, so when the user replaces the another type of alliance chain, the usage rules of the alliance chain need to be replaced, and the usage process of the alliance chain by the user is complicated.

Aiming at the problems in the prior art, the inventor finds that if a virtualized BaaS platform capable of being in butt joint with various types of alliance chains to call various types of alliance chains exists, the technical problem that a user is complicated in the using process of the alliance chains can be solved in the process of researching intelligent contract chain storage and inquiry on the block chains through a block chain BaaS platform. The centralized management and control and unified service of various alliance chains are achieved through the virtualization BaaS platform, no matter which block chain meets the use requirements of users, the block chains can be in butt joint with the corresponding block chains through the virtualization BaaS platform by adopting the same rule, and the process that the users use the alliance chains is simpler and more convenient. Based on the inventive concept, the data processing scheme based on the block chain in the application is designed.

The block chain-based data processing scheme of the present application is explained in detail below.

Fig. 1 is a schematic view of an application scenario of the data processing method based on a block chain provided in the present application, and as shown in fig. 1, the application scenario may include: the terminal device 101, the virtualized BaaS platform 102, BaaS platforms corresponding to multiple types of federation chains (fig. 1 shows three BaaS platforms, which are a BaaS platform 103, a BaaS platform 104, and a BaaS platform 105, respectively), and at least one block chain (fig. 1 shows four block chains, which are a block chain 106, a block chain 107, a block chain 108, and a block chain 109, respectively). The BaaS platform 103, the BaaS platform 104 and the BaaS platform 105 are BaaS platforms corresponding to three different types of block chains; the BaaS platform 103 may be any one of a starfire chain BaaS platform, a long-safety chain BaaS platform, a super-chain BaaS platform, and a communication chain BaaS platform, the BaaS platform 104 may be any one of a starfire chain BaaS platform, a long-safety chain BaaS platform, a super-chain BaaS platform, and a communication chain BaaS platform, and the BaaS platform 105 may be any one of a starfire chain BaaS platform, a long-safety chain BaaS platform, a super-chain BaaS platform, and a communication chain BaaS platform. Illustratively, the BaaS platform 103 may be a starfire chain BaaS platform, the BaaS platform 104 may be a unicom chain BaaS platform, and the BaaS platform 105 may be a long-chain BaaS platform. The

blockchains

106 and 107 may be blockchains corresponding to the BaaS platform 103, the blockchain 108 may be blockchain corresponding to the BaaS platform 104, and the blockchain 109 may be blockchain corresponding to the BaaS platform 105.

For example, in the application scenario shown in fig. 1, when a user wants to perform uplink storage on a blockchain, a request message including uplink requirement information is sent to the virtualized BaaS platform 102 through the terminal device 101. The virtualized BaaS platform 102 acquires the block chain 106 matched with the uplink demand information according to the request information sent by the terminal device 101, and then the virtualized BaaS platform 102 sends a feedback message including the first identifier of the first block chain to the terminal device 101. After receiving the feedback message sent by the virtualized BaaS platform 102, the terminal device 101 generates an uplink request according to the information to be uplink and the first identifier, which are input by the user, and sends the uplink request to the virtualized BaaS platform 102.

The virtualized BaaS platform 102 receives an uplink request sent by the terminal device 101, and determines the BaaS platform 103 corresponding to the block chain 106 based on the first identifier. The virtualized BaaS platform 103 forwards the uplink request to the BaaS platform 103.

The BaaS platform 103 receives the uplink request forwarded by the virtualized BaaS platform 102, and performs an uplink operation, that is, an operation of writing information to be uplink into the block chain 106.

Based on the above process, when the user has any uplink requirement, the user can directly send request information including uplink requirement information to the virtualized BaaS platform through the terminal device, and after the virtualized BaaS platform obtains the target block chain matched with the uplink requirement information, the terminal device sends the uplink request including the target block chain to the virtualized BaaS platform so as to complete uplink operation. That is, the user uses any type of alliance chain and is in butt joint with the virtualized BaaS platform, and the BaaS platform does not need to be replaced; and because the user uses any type of alliance chain to be in butt joint with the virtualized BaaS platform, the user uses any type of alliance chain and adopts the same rule, so that the process of using the alliance chain by the user is simpler and more convenient, and the use experience of the user is improved.

It should be noted that fig. 1 is only a schematic diagram of an application scenario provided in the embodiment of the present application, and the embodiment of the present application does not limit actual forms of various devices included in fig. 1, nor limits an interaction manner between the devices in fig. 1, and in a specific application of a scheme, the configuration may be set according to actual requirements.

It should be noted that the following specific embodiments may be combined with each other, and the same or similar concepts or processes may not be described in detail in some embodiments.

Fig. 2 is an interaction diagram of a first embodiment of a data processing method based on a block chain according to the present application. Referring to fig. 2, the data processing method based on the blockchain specifically includes the following steps:

step S201: the terminal equipment receives uplink requirement information input by a user.

When a user needs to perform uplink storage on a block chain, the user inputs uplink requirement information on terminal equipment, and the terminal equipment generates a request message according to the uplink requirement information input by the user.

In a specific embodiment, the terminal device displays a visual interface, and a plurality of selectable parameter information is displayed in the visual interface, and the plurality of selectable parameter information belongs to the parameter information in the parameter information set. The parameter information in the parameter information set may be divided into different categories, for example, the number of block transactions and the required capacity of the block may be one category of parameter information, and the number of consensus nodes and the consensus policy of the block chain may be one category of parameter information. The user determines the required parameters according to the uplink requirement, and the terminal equipment can obtain uplink requirement information according to the parameter information selected by the user. Wherein the plurality of selectable parameter information may include at least two of:

block transaction number: the maximum value of the transaction number which can be stored in the block can be 100 or 200, and the transaction number of the block is not specifically limited in the embodiment of the application and can be selected according to actual conditions;

required capacity of the block: the block may be a maximum capacity for a deposit transaction, the number of block transactions is related to the required capacity of the block, and illustratively, one transaction is about 250 bytes, and 1M may accommodate 4000 transactions. The required capacity of the block may be 99MB or 50MB, and the required capacity of the block is not specifically limited in the embodiment of the present application and may be selected according to actual situations.

Optionally, the visual interface may further include a "done" icon, and after the user has selected the desired parameter, the "done" icon is clicked. The terminal equipment obtains uplink demand information according to the parameter information selected by the user and generates a request message based on the uplink demand information.

In another embodiment, the terminal device is provided with physical keys. And when the user finishes selecting the required parameters, operating the physical key. The terminal equipment obtains uplink demand information according to the parameter information selected by the user and generates a request message based on the uplink demand information. The physical key can be operated for a preset time length after being pressed for a long time, or can be operated for clicking the physical key, or can be operated for a preset number of times after clicking the physical key.

Step S202: the terminal equipment sends a request message to the virtualized BaaS platform, wherein the request message comprises uplink demand information of a user; the virtual BaaS platform is in communication connection with a plurality of BaaS platforms of various alliance chains.

After the terminal equipment generates a request message according to uplink demand information input by a user, the terminal equipment sends the request message including the uplink demand information of the user to the virtualized BaaS platform. Optionally, the terminal device may send the request message to the virtualized BaaS platform through interfaces such as an API and an SDK. Wherein, the request message includes uplink requirement information of the user.

The virtual BaaS platform and the BaaS platforms corresponding to the various alliance chains can be in communication connection through interfaces, namely the virtual BaaS platform is in communication connection with the BaaS platforms. Wherein at least one block chain can be included under each type of federation chain.

Optionally, the various types of federation chains include, but are not limited to, at least two of the following federation chains: a star fire chain, a communication chain, a Changan chain and a super chain. For example, the blockchain 106, the blockchain 108, and the blockchain 109 in fig. 1 may be three different types of blockchains among a starfire chain, a communication chain, a long-ampere chain, and a super chain. Blockchain 107 may be the same type of blockchain as blockchain 106.

Step S203: the virtualized BaaS platform acquires a first block chain matched with the uplink demand information.

After the terminal equipment sends the request message including the uplink demand information to the virtualized BaaS platform, the virtualized BaaS platform receives the request message including the uplink demand information sent by the terminal equipment. And the virtualized BaaS platform acquires a first block chain matched with the uplink demand information according to the request message containing the uplink demand information.

In one implementation, the first blockchain is one blockchain of multiple types of federation chains corresponding to the multiple BaaS platforms.

In another implementation, block chains matched with the uplink demand information do not exist in the various types of alliance chains corresponding to the BaaS platforms, and at this time, the first block chain is a block chain matched with the uplink demand information and built according to the uplink demand information.

Step S204: and the virtualized BaaS platform sends a feedback message to the terminal equipment, wherein the feedback message comprises a first identifier of the first block chain.

After the virtualized BaaS platform acquires the first block chain matched with the uplink demand information, a feedback message can be sent to the terminal equipment through the interface, wherein the feedback message comprises a first identifier of the first block chain.

Optionally, the first identifier is a unique ID of the first block chain.

It should be noted that, in the embodiment of the present application, the first identifier is not specifically limited, and may be selected according to actual situations.

Optionally, in step S202, the request message sent by the terminal device to the virtualized BaaS platform may further include indication information for indicating a second block chain, where the second block chain may be a block chain that the terminal device wishes to use and is specified by the user, and after the virtualized BaaS platform acquires the first block chain matched with the uplink requirement information and before the virtualized BaaS platform sends the feedback message to the terminal device, the virtualized BaaS platform determines, according to the indication information, whether the second block chain is the same as the first block chain.

When the second blockchain is the same as the first blockchain, the feedback message further includes first reminding information correspondingly, and the first reminding information is used for reminding the user that the second blockchain is the same as the first blockchain.

Optionally, when the second blockchain is different from the first blockchain, the feedback message further includes second reminding information, and the second reminding information is used to suggest to the user to use the first blockchain for uplink operation. Optionally, the second reminding information is further configured to remind the user that the second block chain is different from the first block chain.

When the user specifies the block chain, the request message further includes indication information for indicating the second block chain. And the virtualized BaaS platform determines whether the second block chain indicated by the user is the same as the first block chain which is acquired by the virtualized BaaS platform and matched with the uplink demand information or not according to the indication information contained in the request message. According to the method and the device, the user can know whether the block chain which the user wants to use is consistent with the first block chain which is acquired by the virtualized BaaS platform and matched with the uplink requirement information, and the accuracy of selecting the used block chain by the user is ensured while the user requirement is fully considered.

Step S205: the terminal equipment sends a chaining request to the virtualized BaaS platform, wherein the chaining request comprises a first identifier and information to be chained.

When a user needs to perform uplink storage on a block chain, the user sends an uplink request to the virtualized BaaS platform through the terminal equipment, wherein the uplink request comprises a first identifier and information to be uplink. Optionally, the information to be uplink includes uplink data and a second identifier corresponding to the uplink data.

For example, when the video information needs to be subjected to uplink storage, the uplink data in the to-be-uplink information may include video data, video shooting time, name of the device shooting the video, and the like. When a contract needs to be certified for uplink, the uplink data in the information to be uplink may include the hash value of the contract.

Step S206: and the virtualized BaaS platform sends a chaining request to the first BaaS platform of the first block chain so as to write the information to be chained into the first block chain.

The virtual BaaS platform receives an uplink request sent by terminal equipment, determines a first block chain matched with uplink demand information according to a first identifier in the uplink request, and stores a corresponding relation between the BaaS platform and the block chain. And the virtual BaaS platform determines the BaaS platform corresponding to the first block chain according to the corresponding relation, so that the virtual BaaS platform determines the first BaaS platform of the first block chain. And the virtualized BaaS platform sends a chaining request from the terminal equipment to the first BaaS platform of the first block chain so as to write the information to be chained into the first block chain.

In the data processing method based on the block chain provided in this embodiment, after receiving uplink requirement information input by a user, a terminal device sends a request message including the uplink requirement information of the user to a virtualized BaaS platform. The virtual BaaS platform acquires a first block chain matched with the uplink demand information according to the request message, and sends a feedback message including a first identifier of the first block chain to the terminal equipment. The terminal equipment sends a chaining request comprising a first identifier and information to be chained to the virtualized BaaS platform, and the virtualized BaaS platform sends the chaining request to the first BaaS platform of the first block chain, so that the information to be chained is written into the first block chain.
