Detailed ways

As we all know, the main application scenario of the blockchain is data storage, and the data stored in the blockchain cannot be tampered with. Therefore, at present, almost all business parties will store at least part of their business data in the blockchain when they conduct business with the help of the blockchain.

In other words, for almost all business parties, although the actual business is very different, there is a general requirement for storing business data. However, each business party needs to develop its own business data storage when developing smart contract code. Way of code.

In one or more embodiments of this specification, on the one hand, it is considered that the general requirement of business data storage can be refined, and on the other hand, it is considered that the configuration of the data storage mode can be reflected in a structured data table. Therefore, Develop an automated contract program (or automated contract tool) for use by different business parties. The automated contract program has a built-in data sheet template. The business party can fill in the data sheet template, complete the configuration of the business data storage method, and then automate the contract According to the preset template parsing rules, the program automatically parses the data table template configured by the business party into a smart contract code and returns it to the business party, so the business party does not need to develop this part of the code.

The technical solutions provided by the embodiments of this specification will be described in detail below with reference to the accompanying drawings.

Fig. 1 is a schematic flow chart of a method for generating smart contract codes provided by an embodiment of this specification, which includes the following steps: S100: Provide a set of data table templates to a business party.

The subject of execution of this plan is the automated contract program, and the business party can install the automated contract program on its own computer equipment (such as computers, mobile phones, and tablets) for use.

The automated contract program has a built-in data table template collection (including at least one data table template). The automated contract program can provide a visual interface to the business party, display the data table template collection to the business party, and prompt the business party to Fill in the data sheet template.

When the data table template collection includes more than one data table template, the business party can select one of the data table templates to fill in, or select all the data table templates to fill in.

In the embodiment of this specification, the data table template set includes at least a first data table template. The first data table template includes a feature name field, a feature type field, and a feature description field, and is used to configure the The storage method of the business data of the blockchain.

Of course, as will be further mentioned later, the first data table template may also include more other fields.

S102: Receive at least one set of entry parameters input by the business direction in the first data table template.

Table 1 exemplarily gives a first data table template:

Feature name field	Feature Type Field	Feature description field
To	To	To
To	To	To
To	To	To

Table 1

Table 2 exemplarily shows another first data table template:

Feature name field

Feature Type Field

Feature description field

Table 2

The business party can select a blank entry in the first data table template for input, and each blank entry is used to configure the storage of the characteristics of a certain dimension of the business data.

For Table 1, a number of blank entries have been reserved for the business side to input. For Table 2, the business side can manually add blank entries before inputting.

The "input" mentioned in this article refers to the way the business party fills in the first data sheet template, which can be to enter the field value, or the voice input field value, or in the drop-down menu corresponding to each blank cell Select the field value.

In short, each set of entry parameters input to the first data table template includes a field value corresponding to each field of the first data table template, which is used to characterize the dimension of the business data submitted by the business party. Feature name, feature type, and feature description.

For example, suppose the business party is an e-commerce platform that specializes in selling artworks, and it wants to submit each order data generated in the business to the blockchain for storage. For this reason, when the e-commerce platform uses the automated contract program for configuration, the first data table template can be configured as follows:

Feature name field	Feature Type Field	Feature description field
table	Art	Artwork
art id	String	Artwork logo
art size	String	Artwork size
art type	String	Type of artwork
art owner	String	Art owner

table 3

Among them, table refers to the entire order data, which can be regarded as the table identifier of Table 3, which is the order data of the artwork, so the feature type is the artwork (Art). Art id refers to the identification of the artwork in the order data, art size refers to the size of the artwork, art type refers to the type of artwork (such as painting, sculpture), and art owner refers to the owner of the artwork.

S104: According to the preset template parsing rules, the data table template set after the entry parameters are inputted is parsed into smart contract codes and provided to the business party.

When only the first data table template is included in the data table template set, after the business side completes the configuration of the first data table template, the automated contract program can complete the configuration of the first data table according to the preset template parsing rules The template is parsed into smart contract code and provided to the business party. In practical applications, when a business submits a transaction encapsulated with business data to the blockchain network, the transaction calls the smart contract code, and based on the smart contract code, the business data is defined by the user through the first data table template Storage method for storage.

Through the method shown in Figure 1, an automated contract program is developed for the business side to use. The automated contract program can provide the business side with a data sheet template, so that the business side can configure the business data storage method according to their own needs, and then automate The contract program can automatically generate smart contract code according to the configuration of the business party. Through the embodiments of this specification, because different business parties often have requirements for storing business data on the blockchain, and the requirements for storing business data can often be configured with data tables, a data table template can be developed for this general demand , So that different business parties can use the data table template to configure the storage mode of business data, instead of writing this part of the smart contract code, saving workload and improving efficiency.

In addition, in the embodiment of this specification, the first data table template may also include a function field for configuring at least one of the preset function sets for the business data submitted to the blockchain. For example, see Table 4:

Feature name field	Feature Type Field	Feature description field	Function field
To	To	To	To
To	To	To	To
To	To	To	To

Table 4

The preset function set is preset in the automated contract program and provides several preset functions. The business party can select one or more preset functions when configuring the first data table template, and then the contract code generated by the automated contract program is also included The code corresponding to the preset function selected by the business party will also be included.

For example, the preset function set may include at least one of the following functions: an authority control function, which is used to control access authority to business data; a log function, which is used to generate an operation log for business data; a traceability function, which uses Each business transaction containing business data submitted to the blockchain by the retrospective business party; the data display function is used to output and display business data in a specified display scheme; the trigger effective function is used to set the storage mode configured by the business party The effective time for storing business data.

It should be noted that the preset functions are generally configured with the overall business data as the granularity. Therefore, as shown in Table 3, usually only the first entry contains the field values of the preset functions, for example, see Table 5:

Feature name field	Feature Type Field	Feature description field	Function field
table	Art	Artwork	Access control, log
art id	String	Artwork logo	To
art size	String	Artwork size	To
art type	String	Type of artwork	To
art owner	String	Art critic	To

table 5

In addition, in the embodiment of this specification, the data table template set may also include a second data table template, and the second data table template includes a feature name field and an operation method field, which are used to configure the The operation mode of the business data of the blockchain.

Before parsing the data table template after the entry parameters into the smart contract code, at least one set of entry parameters entered by the business direction in the second data table template can be received; wherein, adding to the second data table template Each set of input parameters includes field values corresponding to each field of the second data table template one-to-one.

Wherein, the field value corresponding to the operation method field includes at least one of the following:

The field value used to characterize the data insertion operation (such as insert);

The field value used to characterize data modification operations (such as update);

Field values used to characterize data query operations (such as query);

The field value used to characterize the data deletion operation (such as delete).

In practical applications, on the one hand, the business party can submit a transaction encapsulated with business data to the blockchain network in order to call the smart contract code to store the business data in a "pre-defined storage method by the business party through the first data table template" On the other hand, after the business data is stored, the business party can also initiate an operation transaction to the blockchain network in order to call the smart contract code to insert, modify, query, delete and other operations on the stored business data (business Party through the pre-defined operation mode of the second data table template).

Table 6 exemplarily shows a second data table template:

Feature name field	Operation method field
To	To
To	To
To	To

Table 6

Since the business party generally inputs for the data table template set, and the first data table template and the second data table template in the data table template set are configured, of course there is an association relationship. In addition, in order to formally reflect the association between the first data table template and the second data table template, the second data table template may also be as shown in Table 7:

Associated table fields	Feature name field	Operation method field
To	To	To
To	To	To
To	To	To

Table 7

Among them, the associated table field may record the table identifier of the first data table template that has been configured.

In this way, corresponding to the configured first data table template shown in Table 3, the configured second data table template may be:

Feature name field	Operation method field
art id, artsize	insert
art owner	update
art id	query
art id	Delete

Table 8

or:

Associated table fields	Feature name field	Operation method field
table	art id, artsize	insert
To	art owner	update
To	art id	query
To	art id	Delete

Table 9

In addition, in the embodiment of this specification, there are multiple implementation manners for parsing the set of data table templates after the entry parameters are input into smart contract codes according to preset template parsing rules. An optional implementation manner is to generate a database schema description corresponding to the set of data table templates after input item parameters, and determine the smart contract code based on the schema description.

For example, for business data (orders) of a certain e-commerce platform, it can be configured by the business party through the first data table template into the following table structure:

{

orderId:string;//Order id

time:string;//Generation time

operatorId:string;//operator id

key:orderId;//table primary key

}

The schema description corresponding to the above table structure is:

namespace ContractTableManager;

table TableManager{

Orders:[Order];

}

table Order{

OrderId:string;

time:string;

operatorId:string;

}

root_type TableManager;

The automated contract program can analyze the structured data (that is, the data in the data table) according to the schema description, generate the code for calling the structured data interface, and then generate the code for calling the method of the interface. In the generated contract code, the operation methods configured by the business party can be used to call these interfaces to obtain data and perform operations.

In addition, in the embodiment of this specification, the automated contract program can also generate a test framework based on the set of data table templates after the entry parameters are entered and provided to the business party for testing the smart contract code. In this way, the business party There is no need to develop a test framework by yourself.
