Referring to fig. 1, fig. 1 is a flowchart illustrating a cloud service-based blockchain construction method according to an exemplary embodiment of the present disclosure, where the cloud service-based blockchain construction method may be implemented by a server or a terminal device.
As shown in fig. 1, a method for building a blockchain based on cloud services according to an embodiment of the present disclosure includes the following steps S110, S120, S130, and S140, where:
step S110: and generating blocks according to the configuration information and creating a plurality of block chain nodes.
Step S120: and calling a target service from the cloud server according to the block and constructing a block chain channel through the target service.
Step S130: and calling a target node in the blockchain nodes to start an intelligent contract deployed in the blockchain channel.
Step S140: the intelligent contracts are synchronized into a plurality of blockchain nodes.
The following describes the steps in detail:
in step S110, the configuration information may include the number of domain names, each domain name, the sort service type, the number of consensus modules, the number of blockchain channels, each blockchain channel name, the number of intelligent contracts, the number of data nodes, the number of data access modules, and the number of secondary nodes.
In the exemplary embodiment of the present disclosure, the block generated according to the configuration information is a created block in the block chain, it should be noted that the block chain is composed of a plurality of connected blocks, each block records a transaction situation in the network for a period of time, and the block may be understood as an account page in the account book. The first block to be constructed earliest is called the founder block and has a unique ID number. Each subsequently created block, except the created block, contains two ID numbers, one being the ID number of the block itself and the other being the ID number of the preamble block. All blocks are connected in sequence through the front-back direction relationship among the ID numbers to form a block chain.
In an exemplary embodiment of the present disclosure, it should be noted that in a blockchain network, each computer participating in the network may receive the name of a blockchain node. In a network, all blockchain nodes are responsible for providing network services. The block link point can be a communication end point or a redistribution point of communication, and is linked to other nodes. Each blockchain node in the network is considered equal.
In step S120, one or more of the above-mentioned blockchain channels may be used, and the blockchain channels are used to connect the blockchain nodes. Optionally, after the blockchain channel is constructed by the target service, the method may further include the following steps: and configuring the block chain channel through the channel name, the node corresponding to the channel and the object corresponding to the channel in the configuration information, and synchronizing the configured block chain channel into a plurality of block chain nodes.

The cloud service is applied to the deployment implementation of the block chain system, so that the automatic deployment of the block chain can be realized, and the deployment cost of the block chain can be simplified. For example, the automatically deployed blockchain can be applied to a proof-deposit system, and since the proof-deposit data is not falsifiable, does not depend on the proof of a third-party organization, and has higher distributed storage security, the cost and difficulty of independent audit, real record management, and compliance with the proof-deposit rule are reduced compared with the traditional proof-deposit system.
In step S130, optionally, the terminal device or the server may receive the intelligent contract uploaded by the user, and further execute the intelligent contract that is deployed in the blockchain channel and is started by the target node in the calling blockchain node.

In an exemplary embodiment of the present disclosure, optionally, after synchronizing the smart contract into a plurality of blockchain nodes, the terminal device or the server may access the constructed blockchain network to the target application. For example, if the blockchain network is applied to a deposit system, the target application may be an application for tracing, an application for checking a main account, or an application for performing a digital asset transaction, and the embodiments of the present disclosure are not limited thereto.
