The invention relates to the field of cloud computing, in particular to a block chain protocol processing device, a processing method and a block chain.

In current industry-level project collaboration across vendors, processes, ownership of application data is a number of organizations that belong in the entire collaboration link. The distributed storage of data of the block chain, and all transaction signatures and verification mechanisms can well solve the trust problem among a plurality of structures, so that all data on the block chain are real and credible. In order to properly manage data on the blockchain, the collaborators need to write special intelligent contracts. At present, there are Remix, ethfile, Truffle, etc. in more commonly used upper layer intelligent contract Integrated Development environments (IDE for short), and there are ether houses, fabics, EOS, etc. in more popular implementations of the bottom layer block chain.
In the Development of the current intelligent contracts, an Integrated Development Environment (IDE) at an upper layer and a blockchain network are tightly coupled, that is, a certain IDE can only debug and compile the intelligent contracts on a specific blockchain network. Therefore, IDE and blockchain network fragmentation cannot be considered when making technology selection.
For different blockchain network types, the following two approaches are mainly adopted in the prior art to solve the above problems:
1. rewriting an existing intelligent contract IDE, wherein the overhead of the mode is basically equal to that of rewriting the existing intelligent contract IDE so as to adapt to the new blockchain network type; even if the rewriting is completed, a developer needs to independently maintain a copy of the intelligent contract IDE, and the secondary migration cost of the new function of the original intelligent contract IDE is extremely high;
2. the method of rewriting the nodes of the block chain network to adapt to the intelligent IDE has strong aggressivity to codes of the nodes of the block chain, damages the original stability of the nodes, and basically cannot be realized for the noninductive and lossless updating and upgrading of the existing nodes in the production network, so the method is not suitable for the production environment.

Detailed Description
The following detailed description of embodiments of the invention refers to the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating embodiments of the invention, are given by way of illustration and explanation only, not limitation.
In the development of the current intelligent contract, the intelligent contract IDE and the blockchain network are tightly coupled, and the communication protocols used by the intelligent contract IDE and the blockchain network are consistent, so that the intelligent contract IDE and the blockchain network cannot be split into consideration when technology selection is performed.
Specifically, as shown in fig. 1A, in the blockchain network a, the nodes directly communicate using the protocol a, the intelligent contract IDE a communicates with the nodes in the blockchain network a using the protocol a, and a developer first writes the intelligent contract in the IDE a, generates a bytecode after the intelligent contract is compiled, and deploys the bytecode to the network a. As shown in fig. 1B, the intelligent contract IDE B and the blockchain network B are developed in the same manner. Taking the interaction relationship between the mainstream Remix IDE and the ethernet blockchain network shown in fig. 3 as an example, since the Remix IDE is originally part of the ethernet project and compatibility with other blockchain networks is not considered, the Remix IDE communicates with the ethernet nodes using the jsonrpc protocol, and each ethernet node also exposes a calling interface to the Remix IDE using the jsonrpc protocol, i.e., the Remix IDE and the ethernet network are tightly coupled, i.e., the input parameters and the output parameters of the corresponding interfaces configured for the same calling request in the Remix IDE and the ethernet network are completely consistent.
If the protocol used by the intelligent contract IDE is different from the protocol of the underlying blockchain network, the intelligent contract IDE does not have cross-platform properties, e.g., the intelligent contract IDE B cannot run on the blockchain network a, and vice versa. For example, in the development of the blockchain network super-link, the main remixtide needs to be migrated to the blockchain network super-link, but the migration process cannot be directly realized because the communication protocols used by the remixtide and the super-link are not consistent.
Specifically, although the implementation manners of different blockchain networks are various, the technologies adopted by these blockchain networks have certain similarities in core concepts, such as Block (Block), Transaction (Transaction), Account (Account), Token (Token), and the like. However, the intelligent contract IDE is not intended for the complex underlying logical implementation of these concepts, but only focuses on the interface invocation of these concepts, and the interfaces on which the intelligent contract IDE relies heavily are: a) and account inquiry: a list of accounts that the IDE may use; b) account balance inquiry: how many tokens are available for a particular account; c) query of blockchain base state: inquiring the latest block ID, the block-out time and the like; d) transaction release: issuing the compiled intelligent contract to a specific block chain network, or executing specific call on the block chain network; e) and inquiring a transaction result: inquiring whether a certain transaction is successful or not and the output result.
For example, taking the interaction process between the Remix IDE and the blockchain network super-link as an example, the Remix IDE uses jsonrpc protocol to communicate with the ethernet node, and the blockchain network super-link uses grpc protocol to expose the call interface to the Remix IDE, as shown in fig. 5. Specifically, an account balance inquiry and transmission interface of the RemixIDE adopts a jsonrpc protocol, namely an Etherhouse address is used as an input parameter and an output parameter; and a grpc protocol adopted by an account balance inquiry interface of the block chain network super chain is that a super chain address is used as an input parameter and an output parameter. Because the protocols adopted by the two interfaces are inconsistent, the communication between the remix ide and the block chain network super chain cannot be directly realized, namely the account balance inquiry process cannot be realized.
Aiming at the defect of tight coupling between an intelligent contract IDE and a block chain network in the prior art, the block chain protocol processing device provided by the invention has the core view of shielding the difference of protocols and interfaces between the IDE and the block chain network so as to decouple the interactive calling of the intelligent contract IDE and the block chain network. The processing device adopts an adapter design mode, and can match the interface of the intelligent contract IDE with the interface in the block chain network, so that the originally incompatible interfaces can work together.
Fig. 3 is a block chain protocol processing apparatus according to an embodiment of the present invention. As shown in fig. 3, the block chain protocol processing apparatus 100 may include: a first interface conversion module 10, configured to convert an input parameter of a first interface 1 into an input parameter of a second interface 2 in a block chain based on a first mapping relationship between the input parameter of the first interface 1 and the input parameter of the second interface 2 in an intelligent contract integrated development environment, where the first interface 1 and the second interface 2 are both configured to implement a call request; and a second interface conversion module 20, configured to convert, based on a second mapping relationship between the output parameter of the second interface 2 and the output parameter of the first interface 1, the output parameter of the second interface 2 corresponding to the call request into the output parameter of the first interface 1.
Taking the interaction process between the Remix IDE and the blockchain network hyperchain as an example, the Remix IDE calls the first interface 1 through jsonrpc, and the input parameter list of the first interface 1 is (param)1，param2，…,paramn) The output parameter is listed as (out)1,out2,…,outm) Wherein, the input parameter and the output parameter are both expressed in a Taifang address mode; the block chain network super chain calls a second interface 2 through a grpc protocol, and an input parameter list of the second interface 1 is (param)1′,param2′,…,paramx') and the output parameter list is (out)1′,out2′,…,outy') wherein the input parameters and output parameters are represented by means of hyperchain addresses. Wherein, the input parameter and the input parameter may be different in type (e.g., shape, character string or date, etc.) and/or sequence.
Specifically, the following explains and explains the procedure of processing the blockchain protocol between the account balance query sending interface of the Remix IDE and the account balance query interface of the blockchain network hyperlink, which is involved in the execution of the account balance (e.g., rmb) query request of the user.
The first case: the Remix IDE calls an account balance inquiry and sending interface through a jsonrpc protocol, an input parameter list of the account balance inquiry and sending interface is a name, the input parameter name is an Ethern address which substantially represents a user name, and the parameter type of the input parameter name is a character type; the output parameter list is "balance (RMB)"), the output parameter "balance (RMB)" is substantially an Etherhouse address representing account balance (RMB), and the parameter type of the output parameter "balance (RMB)" is integer. The method comprises the steps that account balance inquiry is realized on a block chain network super-link, the block chain network super-link calls an account balance inquiry interface through a grpc protocol, an input parameter list is an 'identity card number', the input parameter 'identity card number' is a super-link address which substantially represents a user identity card number, and the input parameter 'identity card number' is of an integer type; the output parameter list is "balance (RMB)"), the output parameter "balance (RMB)" is essentially a hyperlink address representing account balance (RMB), and the parameter type of the output parameter is integer.
And (3) processing a block chain protocol: a user initiates an account balance inquiry request, and after receiving the account balance inquiry request, the RemixIDE calls an account balance inquiry transmitting interface through a jsonrpc protocol; next, the account balance query sending interface calls the blockchain protocol processing apparatus 100, and the first interface conversion module 10 in the blockchain protocol processing apparatus 100 converts the input parameter ("name") of the account balance query sending interface of the remix ide into the input parameter ("identity card number") of the account balance query sending interface of the blockchain network super-link based on the first mapping relationship Map1 ("mapping relationship between name" - "identity card number"); then, the block chain network hyperchain calls an account balance inquiry interface through a grpc protocol, and the account balance inquiry interface acquires a calling result (account balance) corresponding to the calling request based on the converted input parameters; then, the account balance inquiry interface calls the blockchain protocol processing apparatus 100, and the second interface conversion module 20 in the blockchain protocol processing apparatus 100 converts an output parameter ("balance (rmb)") of the account balance inquiry interface corresponding to a call result into an output parameter ("balance (rmb)") of the account balance inquiry transmission interface based on the second mapping Map2 ("balance (rmb)" (ethernet address) - "balance (rmb)"); finally, the account balance inquiry transmitting interface returns the converted output parameter ("balance (RMB)") to the user. For other interfaces in the remix ide and the blockchain network hyperchain, similar methods can be used to complete the communication between the corresponding interfaces configured to implement the same call request, which is not described herein again.
The second case: the RemixIDE calls an account balance inquiry and sending interface through a jsonrpc protocol, an input parameter list of the account balance inquiry and sending interface is (name (Chinese)), the input parameter (name (Chinese)) is substantially an ether house address representing the Chinese name of a user, and the parameter type of the input parameter (name (Chinese)) is a character type; the output parameter list is "balance (RMB)"), the output parameter "balance (RMB)" is substantially an Etherhouse address representing account balance (RMB), and the parameter type of the output parameter "balance (RMB)" is integer. The method comprises the steps that account balance inquiry is realized on a blockchain network super-link, the blockchain network super-link calls an account balance inquiry interface through a grpc protocol, an input parameter list is (name (English)), the input parameter (name (English)) is a super-link address which substantially represents an English name of a user, and the parameter type of the input parameter (name (English)) is a character type; the list of output parameters is "balance (dollars)", which is essentially a hyperlink address representing the account balance (dollars), and the parameter type of the output parameter is integer.
For the processing procedure of the blockchain protocol in the second scenario, reference may be made to the processing procedure of the blockchain protocol in the first scenario, which is not described herein again.
The first mapping relationship Map1 between the input parameters and the second mapping relationship Map2 between the output parameters of the two interfaces may be determined manually, or may be determined by a screening module, a first mapping relationship establishing module, and a second mapping relationship establishing module, which are described below.
In the above embodiment, although the RemixIDE and the blockchain network hyperchain cannot directly interact, the "session" between the two can be translated by the blockchain protocol processing apparatus 100. Assuming that the interface set on which the Remix IDE depends is a, which includes function modules (or functions) { a1, a2, …, an }, and the interface set of the hyperchain is B, which includes function modules { B1, B2, …, bm }, the block chain protocol processing apparatus 100 is implemented by using the interface set B to simulate the interface set a, so that the Remix IDE still assumes that the interface set is a taifang network, as shown in fig. 5.
The first mapping relation and the second mapping relation can be determined by a screening module, a first mapping relation establishing module and a second mapping relation establishing module. As shown in fig. 4, the device 100 for processing a block chain protocol may further include: a screening module 30, configured to traverse an interface set of a block chain to screen the second interface corresponding to the first interface; a first mapping relationship establishing module 40, configured to establish the first mapping relationship according to the input parameter of the first interface and the input parameter of the second interface; and a second mapping relationship establishing module 50, configured to establish the second mapping relationship according to the output parameter of the first interface and the output parameter of the second interface. Wherein the second interface may include: a functional block or a combination of functional blocks.
For an account balance query request initiated by a user, an account balance query sending interface configured for implementing the request in the remixtide is a function module a1, when the function module a1 calls the blockchain protocol processing apparatus 100, the screening module 30 in the blockchain protocol processing apparatus 100 traverses the interface set of the blockchain network hyperchain, checks whether there is a function module therein cooperating with the function module a1 to implement the request, and if there is a function module b1, the first mapping relation establishing module 40 is based on an input parameter (param) of the function module a11,param2,…，paramn) And the input parameter (param) of the function block b11′,param2′,…,paramx'), establishing a first mapping Map1 between the input parameters of the two modules; and the second mapping relation establishing module 50 outputs a parameter (out) based on the function module a11,out2,…,outm) And the output parameter (out) of the function block b11′,out2′,…，outy') a second mapping Map2 between the output parameters of the two modules is established.If not, interface b 1' configured to fulfill the account balance inquiry request is simulated by a combination of multiple function modules, or by a combination of multiple function modules and adding a new interface (i.e., business logic).
For example, for a request issued by a transaction (e.g., a transfer) initiated by a user, the transaction sending interface configured to implement the request in the remix ide is function module a1, when function module a1 calls the blockchain protocol processing apparatus 100, the screening module 30 in the blockchain protocol processing apparatus 100 traverses the interface set of the blockchain network hyperchain, checks that there is no function module b1 cooperating with function module a1 to implement the request, but function module c1 can implement the transaction generating function and function module d1 can implement the transaction executing function, that is, the issuance of the transaction can be implemented by the combination of function module c1 and function module d1 (equivalent to the transaction issuing interface). The input parameter list of the function module a1 is (transfer account "," amount "," user signature "), the input parameters" transfer account "," amount "and" user signature "substantially represent the ether house address of the transfer account, the transfer amount and the user signature, and the parameter types of the input parameters are character type, integer type and character type respectively; the output list is the 'transaction number', the output parameter 'transaction number' is the Ethern address which essentially represents the transaction number, and the parameter type of the output parameter is character type. The input parameter list of the function module c1 is (transfer account, amount, user signature), the input parameters ' transfer account, amount ' and user signature ' are essentially hyperlink addresses representing transfer account, transfer amount and user signature, and the parameter types of the input parameters are character type, integer type and character type respectively; the output parameter list is ("transaction to be executed"), the output parameter "transaction to be executed" is essentially a hyperlink address representing the transaction to be executed, and the parameter type of the output parameter is a custom type. The input parameter list of the function module d1 is ("transaction to be executed"), the input parameter "transaction to be executed" is essentially a hyperlink address representing the transaction to be executed, and the parameter type of the input parameter is a custom type; the output parameter is the 'transaction number', the output parameter 'transaction number' is essentially a hyperlink address representing the transaction number, and the parameter type of the output parameter is character type.
For this case, the first mapping relationship establishing module 40 establishes a first mapping relationship Map1 between the input parameters of the two modules (i.e. the mapping relationship between the house ethernet addresses and the hyperlink addresses representing the transfer accounts, amounts and user signatures) based on the list of input parameters of function module a1 ("transfer account", "amount", "user signature") and the list of input parameters of function module c1 ("transfer account", "amount", "user signature"); and the second mapping relationship establishing module 50 establishes a second mapping relationship Map2 (i.e. a mapping relationship between the ethernet address representing the transaction number and the hyperlink address) between the output parameters of the two modules based on the output parameter ("transaction number") of the function module a1 and the output parameter ("transaction number") of the function module d1, that is, on the hyperlink side of the blockchain network, the input parameters of the function module (e.g. the function module c1) which executes the tasks for the first time are the input parameters of the second interface 2 according to the order of executing the transaction releases; the output parameter of the function module that finally executes the task (e.g., function module d1) is the output parameter of the second interface 2. The processing procedure of the blockchain protocol for transaction issuance is described in detail below.
In the above process of checking whether there is a function module that can implement the user request matching with the function module a1, the filter module 30 may check the function description about the function module in the interface document; if the document is missing, the definition of the function module (such as the function signature) is checked.
After the first mapping relationship and the second mapping relationship are established, the mapping relationships may be stored for subsequent use. Thus, as shown in fig. 5, the block chain protocol processing apparatus may further include: a database 60 for storing the first mapping relationship and the second mapping relationship. The database 60 may be a lightweight key-value pair database (level DB) that enables light and fast storage of mapping relationships.
In the process of executing the account balance inquiry request of the user, the block chain protocol processing device needs to determine the information of the block chain network to be connected, can smoothly complete the connection between the block chain protocol processing device and the block chain network, and executes the protocol conversion between the intelligent contract IDE and the block chain network and the calling process corresponding to the request. As shown in fig. 5, the block chain protocol processing apparatus may further include: and a file loader 70 for loading the blockchain to be connected. In addition, the file loader 70 may also be used to load other configuration files of the local user, for example, public and private key files of the user test account; and/or for signing transactions to verify that they are legitimate (e.g., a certificate for a blockchain network, which is allowed to execute only if the certificate is legitimate).
Each blockchain network needs to be configured with a unique client for defining an interface between nodes of the blockchain network to allow communication between the nodes using the defined interface. As shown in fig. 5, the block chain protocol processing apparatus 100 may further include: and the client 80 is used for defining and realizing the interface of the blockchain network. For example, for a blockchain network hyperchain, the client 80 specifies its interface as one that employs the grpc protocol. The client 80 may send the output result of the first interface conversion module 10 to the super link node of the blockchain network without processing; similarly, the output result of the block chain network hyperlink node may be sent to the second interface conversion module 20 without processing. Of course, the first interface conversion module 10 and the second interface conversion module 20 can directly communicate with the blockchain network hyperlink node.
In particular, the process of executing a transaction (e.g., a transfer) issue request is explained and illustrated in detail using the interaction diagram between the blockchain network hyperchain and the Remix IDE shown in fig. 5 as an example.
The first mapping relation Map1 and the second mapping relation Map2 (see the above content in detail) are determined in advance by the screening module 30, the first mapping relation establishing module 40 and the second mapping relation establishing module 50 (not shown), and the first mapping relation Map1 and the second mapping relation Map2 are stored in the database 60.
In the case that the first mapping Map1 and the second mapping Map2 are stored in advance, a user initiates a request for issuing a transaction (e.g., a transfer), and after receiving the request, the Remix IDE calls a transaction issuing and sending interface through a jsonrpc protocol; then, the transaction issuance dispatch interface calls the blockchain protocol processing device 100, and the first interface conversion module 10 in the blockchain protocol processing device 100 converts the input parameters ("transfer account", "amount", "user signature") of the transaction issuance dispatch interface into the input parameters ("transfer account", "amount", "user signature") of the function module c1 in the transaction issuance interface, which is responsible for transaction generation task, based on the first mapping Map1 (i.e., the mapping between the etherhouse address and the hyperlink address representing the transfer account, amount and user signature); then, the client 80 receives the input parameters of the function module c1 and forwards them to the function module c1 of the blockchain network hyperchain without processing, and based on the converted input parameters, the function module c1 outputs the transaction to be executed; then, the function module d1 in the transaction issuing interface, which is responsible for the transaction execution task, executes the corresponding transaction issuing and obtains the call result (transaction number) corresponding to the request based on the transaction to be executed; then, the client forwards the call result to the second interface conversion module 20 in the blockchain protocol processing apparatus 100 without processing, and based on the second mapping Map2, the second interface conversion module 20 converts the output parameter ("transaction number") corresponding to the call result of the transaction issue interface of the blockchain network hyperchain into the output parameter (transaction number) of the transaction issue sending interface of the Remix IDE; and finally, the transaction issuing and sending interface of the Remix IDE returns the converted output parameters to the user.
In summary, the present invention creatively converts the input parameters of the first interface for implementing the call request in the intelligent contract IDE into the input parameters of the corresponding second interface in the blockchain through the first mapping relationship, and converts the output parameters of the second interface corresponding to the call request into the output parameters of the first interface through the second mapping relationship, so as to shield the difference of the protocol and the interface between the intelligent contract IDE and the blockchain network, thereby economically and effectively implementing the decoupling of the interactive call of the intelligent contract IDE and the blockchain network, and is suitable for the production environment.
