Detailed Description

In order that those skilled in the art will better understand the technical solutions in this specification, a clear and complete description of the technical solutions in one or more embodiments of this specification will be provided below with reference to the accompanying drawings in one or more embodiments of this specification, and it is apparent that the one or more embodiments described are only a part of embodiments of this specification, not all embodiments. All other embodiments, which can be made by one or more embodiments of the present disclosure without inventive faculty, are intended to be within the scope of the present disclosure.

Example 1

Referring to fig. 1, a schematic diagram of steps of a data operation method based on a plurality of state organization modes on a blockchain is provided in an embodiment of the present disclosure, it should be understood that the method is applied to the blockchain, and an execution subject of the method may be a data operation device based on a plurality of state organization modes on the blockchain, and the device may be deployed in a blockchain network through an intelligent contract, and may specifically be a virtual machine executing the intelligent contract. The data manipulation method may include the steps of:

step 102: and determining the operation content and the mounting point of the data operation based on the received data operation request.

It should be understood that the operation content includes not only specific operation data, but also the operation type of the present operation. The operation types at least comprise: read operations, write operations, compute hash operations, snapshot restore operations.

The data operation request may be sent by a terminal outside the blockchain network, or may be sent by a node device in the blockchain network.

The data operation request may carry the operation content required by the current data operation and the mounting point corresponding to the state organization mode used by the current data operation. That is, the user can select different state organization modes to perform data operation according to the way of adding the mounting point in the data operation request according to the own requirement.

Step 104: and calling matched operation interfaces from an interface set configured on the blockchain in advance based on the operation content.

In the embodiment of the present specification, the interface set may be configured by: based on different operation types, abstractly defining a set of operation interfaces corresponding to each operation type; and respectively mounting a plurality of state organization modes maintained by the blockchain for each operation interface under a default root directory.

In concrete implementation, a set of public interfaces can be virtually generated according to different operation types, and a series of operation methods which need to be met in different state organization modes are abstracted. As shown with reference to Table 1, there are listed 5 common interfaces, read operations, write operations, computational hash operations, snapshot operations, and snapshot recovery operations. Each operation type is also defined with an interface function, and a description of each interface.

TABLE 1

The path corresponding to the read operation is, for example, 0xabcd/0x1 in mpt example and table_name/index/x_key in mysql example. The way of computing the root hash is not limited, but the root hash must also be changed if any of the values change.

It should be understood that each state organization may implement these interfaces, and the specific implementation is not limited. But must meet basic functional requirements such as writing a value to a particular path and then reading that path, the same value will be obtained. Taking a snapshot and then resuming the snapshot, the state must remain unchanged. Wherein a separate micro-service may be provided for each state organization.

Step 106: and inquiring a state organization mode requested by the operation from a preset operation registry of the blockchain based on the mounting point.

Firstly, there is a root state organization mode, which also implements the aforementioned interfaces, but is provided by default by the chain itself, and the mount point defaults to/root. Under the root directory, an operation registry is implemented. Referring to table 2, names of state organization schemes, mount points, micro-service information, and the like corresponding to data operations are recorded therein. It should be understood that table 2 only shows a partial state organization, but also includes other types of state organization, which are not listed here. Any of the operations described in the operation registry may be used in the blockchain network.

Name of the name	Mounting point	Microservice information
			Mpt	/root/mpt	ip:port
Mysql	/root/mysql	ip:port

TABLE 2

Wherein the operation registry and the contracts of the operation registry can be realized in the form of native contracts.

In the embodiment of the present disclosure, the preset operation registry is obtained by registering under a root directory by sending a transaction. When the method is specifically implemented, the corresponding micro-service can be operated, then the registration is carried out under the catalog in a transaction sending mode, and the loading action is completed after the transaction is uplink, namely the registration is completed.

It should be appreciated that the registry of operations completed by registration may be updated, e.g., by adding or deleting state organization patterns therein. Therefore, the system can adapt to various requirements.

Thereafter, when executing step 106, a state organization manner matching with the items mounted by the mounting points may be queried from the preset operation registry based on the mounting points determined in step 102.

Step 108: and calling an operation method corresponding to the state organization mode in the operation interface.

An implementation scheme is that when the operation type of the operation content is a read operation and/or a write operation, the operation content further comprises an operation path;

step 108 is specifically performed as:

and firstly, cutting the mounting points from the operation path based on the determined state organization mode to obtain a relative path.

And secondly, calling an operation method corresponding to the state organization mode under the operation interface by taking the relative path as a parameter, and obtaining an operation return value.

Taking a read operation as an example, the intelligence is about in the process of executing in the virtual machine, if it is required to read a value in one operation path, such as/root/mpt/0 xabcd/0x1.

(1) The read operation interface of the root directory is called.

(2) And inquiring the corresponding specific state organization mode from the registry under the root directory.

Wherein, the query and the matching find mpt, the corresponding mounting point is/root/mpt, and the micro service information is ip: port.

(3) And cutting the operation path to obtain a relative path 0xabcd/0x1 after the mounting point path is removed.

(4) The read interface of the corresponding micro service is called mpt with the corresponding path 0xabcd/0x1 as a parameter to obtain a return value.

(5) And returning the return value to the virtual machine as the return value of the root directory read operation, namely the value to be read at this time.

In the embodiment of the present specification, the writing operation is similar, and will not be described here again.

In another implementation manner, when the operation type of the operation content is a hash operation, step 108 may be specifically performed as: calling a root hash method of each mounting point in a computing root hash interface; and hashing each root hash value with the content under the root directory to obtain a final state hash value.

In particular, when transactions in each block are completed and operations on states are completed, a state_root hash of the entire world state needs to be calculated. The blockchain may invoke a root_hash operation of the root directory. In root_hash implementation of the root directory, a root_hash method of each mounting point is called according to the registry, and a corresponding root_hash is obtained. And then, carrying out hash on the root_hash and the content stored in the root directory, so as to obtain a final state_root.

Snapshot and snapshot recovery, are also similar recursive operations. The blockchain may invoke a corresponding method of the root directory. The internal implementation of the method can recursively call the corresponding method of each instance mounted below while the related operation of the root directory is completed. The snapshot generated file may be placed in a designated directory. This directory is initially set as a configuration parameter for the blockchain. Recovery from the snapshot is also read from the specified directory. It should be appreciated that the principles of snapshot and snapshot recovery operations are similar to those described above for read and write operations and for computing hash operations, and are not described in detail herein.

It should be understood that, in this specification, a plurality of state organization manners are registered in the preset operation registry of the blockchain, where the plurality of state organization manners at least includes some or all of the following: merck compressed prefix tree, sparse merck tree, and relational database. Other state organization schemes that may be used in blockchain technology may also be included, and are not specifically recited herein.

Through the technical scheme, the interface set is preconfigured in the blockchain, the blockchain can simultaneously support a plurality of state organization modes based on the plurality of state organization modes which are registered through mounting, and when a data operation request is processed, a matched operation interface can be called based on the determined operation content and mounting point of the data operation, and an operation method corresponding to the state organization mode is called in the operation interface. Therefore, a plurality of state organization modes are supported on the blockchain at the same time, so that a user can flexibly select according to own business requirements.

the query module 206 queries a state organization mode requested by the operation from a preset operation registry of the blockchain based on the mounting point;

and a method calling module 208, for calling the operation method corresponding to the state organization mode in the operation interface.
