Detailed Description

In order to make the technical solutions in the present specification better understood, the technical solutions in one or more embodiments of the present specification will be clearly and completely described below with reference to the accompanying drawings in one or more embodiments of the present specification, and it is obvious that the one or more embodiments described are only a part of the embodiments of the present specification, and not all embodiments. All other embodiments that can be derived by a person skilled in the art from one or more of the embodiments described herein without making any inventive step shall fall within the scope of protection of this document.

Example one

Referring to fig. 1, a schematic step diagram of a data operation method based on multiple state organization manners on a blockchain provided by an embodiment of the present specification is provided, 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 multiple state organization manners on the blockchain, and the device may be deployed in a blockchain network through an intelligent contract, and specifically may 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 an operation type of the operation. The operation types at least include: read operation, write operation, hash calculation operation, snapshot operation, and snapshot recovery operation.

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

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

Step 104: and based on the operation content, calling a matched operation interface from an interface set configured on the block chain in advance.

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

During concrete implementation, a set of common interfaces can be virtualized according to different operation types, so that a series of operation methods required to be met by different state organization modes can be abstracted. Referring to table 1, 5 common interfaces of read operation, write operation, compute hash operation, snapshot operation, and snapshot restore operation are listed here. Each operation type is also defined with interface functions, and a specification for each interface.

TABLE 1

Among them, the read operation corresponds to a path, such as 0xabcd/0x1 in the case of mpt and table _ name/index/x _ key in the case of mysql. The operation of computing the root hash is not limited in the manner in which it is computed, but if any one of the values changes, the root hash must also change.

It should be understood that each state organization may implement the interfaces described above, and the specific implementation is not limited. But must satisfy basic functional requirements such as writing a value to a particular path and then reading that path to obtain the same value. Taking a snapshot and then resuming the snapshot, the state must remain unchanged. Wherein a separate microservice may be provided for each state organization.

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

First there is a root state organization, which also implements the aforementioned interfaces, but is provided by the chain itself by default, with the mount point defaulted as a/root. Under the root directory, an operation registry is implemented. Referring to table 2, the name of the state organization mode, the mount point, the micro service information, etc. corresponding to the data operation are recorded. It should be understood that table 2 only shows a partial state organization, and also includes other types of state organizations, which are not listed here. All that is in the operation registry can be used in the blockchain network.

Name (R)	Hanging point	Micro service information
			Mpt	/root/mpt	ip:port
Mysql	/root/mysql	ip:port

TABLE 2

Wherein the operating registry and the contracts of the operating registry are implemented in the form of native contracts.

In the embodiment of the present specification, the preset operation registry is obtained by registering under the root directory by means of a transaction. During specific implementation, the corresponding micro-service can be operated, then registration is carried out under a follow-up catalog in a transaction issuing mode, and after the transaction is linked up, mounting action is finished, namely registration is finished.

It should be appreciated that the operational registry in which registration is complete may be updated, e.g., adding or deleting state organizations therein. Therefore, the device can adapt to various demand environments.

Thereafter, when step 106 is executed, a status organization mode matching the items mounted by the mounting point can be inquired from the preset operation registry based on the mounting point determined in step 102.

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

When the operation type of the operation content is a read operation and/or a write operation, the operation content also comprises an operation path;

step 108 is specifically performed as:

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

And step two, calling the 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 the read operation as an example, the intelligent agent is in the process of executing in the virtual machine, and if necessary, reads the value in an operation path, such as/root/mpt/0 xabcd/0x 1.

①, a read operation interface to call the root directory.

②, searching the registry under the root directory for its corresponding specific state organization mode.

The found result of the query and the matching is mpt, the corresponding mounting point is/root/mpt, and the micro-service information is ip: port.

③, the operation path is cut to obtain a relative path 0xabcd/0x1 after the mounting point path is removed.

④, calling the read interface of the micro service corresponding to mpt by taking the relative path 0xabcd/0x1 as a parameter to obtain a return value.

⑤, 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 embodiments of the present specification, the writing operation is similar to the operation, and is not described herein again.

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

In particular implementation, after the transaction in each block is completed and the operation on the state is also 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 the root directory root _ hash implementation, a root _ hash method of each mount point is called according to the registry to obtain a corresponding root _ hash. And then, hashing the root _ hash and the content stored under the root directory to obtain the final state _ root.

Snapshot and snapshot restore are also similar recursive operations. The blockchain may call a corresponding method of the root directory. The internal implementation of the method can make the relevant operation of the root directory and recursively call the corresponding method of each instance mounted below. The files generated by the snapshot can be placed in a specified directory. This directory is set as a configuration parameter for the block chain from the beginning. The recovery from the snapshot is also read from the specified directory. It should be understood that the principles of the snapshot and snapshot restore operations are similar to the principles of the read-write operations and the compute hash operations described above and will not be 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 block chain, and the plurality of state organization manners at least include some or all of the following: a merkel compressed prefix tree, a sparse merkel tree, and a relational database. Other state organization schemes that may be used in blockchain techniques may also be included and are not listed here.

According to the technical scheme, the interface set is pre-configured in the block chain, the block chain can simultaneously support multiple state organization modes based on the multiple state organization modes which pass the mounting registration, and when a data operation request is processed, the matched operation interface can be called based on the determined operation content and mounting point of the data operation, and the operation method corresponding to the state organization mode is called in the operation interface. Therefore, multiple state organization modes are simultaneously supported on the block chain, and a user can flexibly select the state organization modes according to the service requirement of the user.
