The intelligent agent creates an unprecedented digital currency form, namely the bitcoin, is unique in solving the problem of data consistency among a plurality of dynamic nodes under the condition of no central coordination, and shows the great value of the block chain technology. The block chain is used as a unique distributed database and has natural advantages of distributed safety, non-tampering, uniqueness, non-reversibility and the like. The characteristics of blockchain technology make more and more fields focus on the application of blockchains. In the field of internet of things, the block chain technology can be applied to ensuring the accuracy of data sources and the safe transmission and storage of data. Specific examples include, but are not limited to, the following application scenarios: the environmental data such as temperature, humidity, PM2.5 concentration and the like acquired by the environmental sensor in public places are transmitted and stored through the block chain, so that the data acquired by the meteorological bureau are safer and more reliable. Water meters, electric meters, gas meters and the like in the home are connected into a block chain network, and automatic payment of life resource consumption can be realized. The door lock of the house is accessed into the block chain network, the transfer of the door lock control right and the sharing of the house can be realized through the intelligent contract of the block chain, the delivery of rent is realized through the block chain network, and wider sharing economy is realized. Aiming at the application scenes, how to safely and efficiently realize the access of the Internet of things equipment with limited hardware resources to the blockchain network is a key problem.
Most of the internet of things edge devices are thin terminals with limited resources, and currently, the popular internet of things devices and data access modes are internet of things management platforms based on a cloud server and connected to centralized management, such as an aricloud internet of things platform and a Baidu cloud internet of things platform. In such a centralized management architecture model, the internet of things application lacks functions of auditing and auditable and also lacks a mechanism for independently verifying data integrity, privacy conditions, or reliability. This approach leads to problems of insecurity of data, easy tampering, data opacity, etc.
In order to solve the above problems, with the development of a block chain technology and the advantages of distributed security, inflexibility, traceability and the like, researchers provide that the internet of things equipment and data are directly accessed to a block chain network. At present, the mode of accessing the Internet of things equipment to a block chain is mainly a light node mode, and in the light node mode, the light node mode is realized by deploying light nodes at the Internet of things terminal. In the mode, the Internet of things equipment can be directly accessed to the block chain network service, and the method has good safety, but has the defect that the Internet of things equipment is required to have at least hardware conditions such as raspberry pi (Raspberry Pi), can not support a very common singlechip in the Internet of things terminal, and has great limitation.
The first embodiment:
in order to solve the problem that the application limitation is large due to the fact that a block chain access mode provided in the related art requires that an internet of things terminal has a strong hardware condition, the present embodiment provides a block chain service access method applied to a block chain service access system, as shown in fig. 1, the block chain service access system is a system architecture diagram of the block chain service access system provided in the present embodiment, and includes three major parts: the system comprises an internet of things terminal, a block chain proxy node service and a block chain network, wherein the internet of things terminal is provided with a Message construction client, the client can be preferably realized by adopting an MQTT (Message queue Telemetry Transport protocol) client, the block chain proxy node service comprises a plurality of SDK (Software Development Kit) proxy nodes, each SDK proxy node is provided with a Message proxy server and an SDK rear end, correspondingly, the Message proxy server can be preferably realized by adopting the MQTT server, and the block chain network is provided with a plurality of different block chain nodes.
As shown in fig. 2, which is a basic flowchart of the block chain service access method provided in this embodiment, the block chain service access method provided in this embodiment includes the following steps:
Specifically, the network protocol of this embodiment may be preferably implemented by using an MQTT protocol, which is a lightweight communication protocol based on a Publish/Subscribe (Publish/Subscribe) mode, and the protocol is constructed on a TCP/IP protocol. MQTT has the advantage of providing real-time reliable messaging services to remote devices with minimal code and limited bandwidth. As an instant messaging protocol with low cost and low bandwidth occupation, the MQTT is more suitable for the Internet of things thin terminal with limited hardware conditions.
In this embodiment, the hash algorithm and the digital signature verification algorithm of the corresponding blockchain system are implemented at the terminal node of the internet of things, a blockchain message can be directly constructed at a message construction client deployed at the terminal of the internet of things, and then the blockchain message is sent to the blockchain agent node through a network request.
Specifically, the blockchain network provides SDKs in various languages, including Go, Java, JavaScript, and the like, and the client needs to interact with the blockchain network service through the SDKs. The SDK operation needs certain hardware resource support, and general Internet of things equipment is difficult to meet requirements. In the system architecture design, the problem of the connection block chain service of the Internet of things thin terminal with limited hardware resources is solved by introducing a block chain SDK proxy node.
In this embodiment, the message proxy server may be an MQTT server, the block chain SDK proxy node deploys the MQTT server and a block chain SDK back end, the MQTT server may receive a block chain message sent by the internet of things terminal, and the block chain SDK back end sends the message to the block chain network, so that the block chain SDK proxy node serves as a bridge between the internet of things terminal and the block chain network.
Specifically, the internet of things terminal interacts with the blockchain network through the SDK proxy node to obtain blockchain services, and similarly, response data of the blockchain network is forwarded to the internet of things terminal through the blockchain proxy node.
As shown in fig. 3, which is a schematic flow chart of a method for allocating a blockchain proxy node provided in this embodiment, in an optional implementation manner of this embodiment, before the step of sending a blockchain message to the blockchain proxy node by using a preset network protocol, the internet of things terminal specifically includes the following flows:
301, the terminal of the internet of things sends a node allocation request to a blockchain network through an initial blockchain agent node;
and step 303, the blockchain network returns the node information of the target blockchain agent node to the internet of things terminal through the initial blockchain agent node.
Specifically, the registration intelligence contract of the present embodiment includes a plurality of legally registered blockchain proxy nodes. In practical applications, a device with limited terminal resources may connect to the blockchain SDK proxy service node to obtain information on the blockchain. The connection mode enables the IOT equipment to trust the proxy nodes to a certain extent, and if the proxy nodes are attacked by security, the proxy nodes can provide false blockchain information for the IOT equipment.
Therefore, the embodiment provides a dynamic selection mechanism for the block chain SDK proxy service node, which allows the internet of things device to obtain the block chain SDK proxy service node list instead of relying on a single trusted node. In a blockchain network, a system will deploy a registration contract for blockchain SDK proxy nodes, and any node that provides blockchain SDK proxy services will need to register through the registration of the intelligent contract (chain code). The whole communication will include the following stages: firstly, a service provider of any operation block chain SDK proxy node needs to register in a block chain SDK proxy node registration contract; secondly, the terminal node of the Internet of things interacts with the registration contract of the SDK proxy node of the block chain through the SDK proxy node of the initial block chain for the first time, and the contract selects one service node from the node list to return; and finally, the terminal of the Internet of things interacts with the block chain network through the newly acquired SDK proxy node to acquire the block chain service.
In this embodiment, a specific procedure for dynamically and securely selecting the proxy node is introduced as follows: a. the terminal of the Internet of things requests dynamic allocation of the agent nodes through the initial agent nodes and is used for interacting with the block chain network in subsequent services; b. the initial agent node requests to register an intelligent contract (chain code); c. registering contract dynamic allocation block chain SDK proxy nodes and returning the SDK proxy nodes to the initial proxy nodes; d. the initial proxy node transfers the distributed proxy node information to the Internet of things terminal; e. the terminal of the Internet of things requests block chain service through the newly distributed agent nodes; f. and connecting the newly distributed agent nodes with the block chain network to provide block chain transfer service for the terminal of the Internet of things.
With the increase of terminals of the internet of things which want to access the blockchain network, the blockchain SDK proxy node is used as an important transfer node, and the security and the performance of the blockchain SDK proxy node directly influence the security and the performance of the blockchain network accessed by the internet of things. The embodiment dynamically and safely selects the block chain agent node, avoids single-point faults and potential safety hazards of the fixed node, and can effectively improve the overall safety and performance of the system.
In addition, the present embodiment further describes an implementation algorithm of the above-mentioned registered intelligent contract, where the inputs of the algorithm are: without input, the output is: dynamically selecting a proxy node connection information; a. declaring a proxy node list chain code structure body, wherein the structure body attribute comprises a node name and a node connection address, the node name is used as the key value of the map, and the node connection address is used as the value of the map; b. compiling a node registration Register () method for registering qualified proxy nodes; writing a getRandomNode () method, and randomly returning to an agent node; c. the method comprises the following steps of realizing an Init () function and an Invoke () function of a chain code, wherein the Init () function is an interface which must be realized by the chain code, the processing logic when the chain code is initialized or upgraded is realized by the Init () function, and the logic which is processed when the chain code is called or inquired in operation is realized by the Invoke () function, namely, the Register () function and the getRandomNode () function are called; d. main () main function is implemented, and the shim.start () method is called in the main function.
Further, in an optional implementation manner of this embodiment, the method for acquiring a blockchain proxy node further includes: periodically counting performance parameters of a plurality of legally registered block chain agent nodes by a block chain network; and the blockchain network correspondingly records the security levels aiming at a plurality of legally registered blockchain agent nodes in the registered intelligent contract according to the performance parameters.
Correspondingly, the step of querying and registering the intelligent contract based on the node allocation request and determining the target blockchain proxy node in the blockchain network specifically includes: the block chain network inquires and registers an intelligent contract based on the node distribution request; and the blockchain network determines the blockchain agent node with the highest security level in the registered intelligent contract as the target blockchain agent node.
Specifically, in this embodiment, the dynamic allocation manner of the target blockchain agent nodes may be random allocation or regular allocation, and in order to ensure the security and performance of the allocated agent nodes to the maximum extent, the intelligent registration contract of this embodiment may track the historical performance of each agent node, and then give a certain security incentive to each agent node according to the performance, where the performance is positively correlated with the security level, and then allocate the agent node with the highest security level in the registration contract to the internet of things terminal according to the node allocation request.
Further, in another optional implementation manner of this embodiment, the step of determining the target blockchain proxy node by querying the registration intelligent contract based on the node allocation request in the blockchain network specifically includes: the method comprises the steps that a block chain network obtains a terminal attribute or a target request service attribute of an Internet of things terminal; the blockchain network inquires a registration intelligent contract based on the node allocation request, and determines a blockchain proxy node corresponding to the terminal attribute or the target request service attribute as a target blockchain proxy node. In other implementations, the blockchain proxy nodes may also be adaptively allocated according to the difference between the terminals of the internet of things requesting access to the blockchain service or the difference between services requested by the terminals of the internet of things, so as to meet the adaptability between the terminals or services and the nodes, and further ensure the performance of the blockchain service.
As shown in fig. 4, which is a flowchart illustrating a method for creating a blockchain SDK client provided in this embodiment, in an optional implementation manner of this embodiment, before the step of invoking the blockchain SDK client by the target blockchain proxy node and forwarding a blockchain message received by the message proxy server to a blockchain network, the method specifically includes the following steps:

In addition, the embodiment also takes a super account book block chain network as an example, provides a specific block chain service access implementation, and details of a communication method and a process of interaction between an internet of things terminal and the super account book network through a block chain SDK proxy service node will be described. Fig. 5 is a specific flowchart of the method for interacting the internet of things terminal and the super ledger block-chain network provided in this embodiment, and the detailed steps are as follows:
