Blockchain node detection method and device, equipment and medium

Abstract

The invention provides a blockchain node detection method. The blockchain node detection method comprises the steps that an injector manager intercepts a first request message which is sent by a blockchain first node and is used for obtaining a current service state; the injector manager determines a first scene operation used for simulating an abnormal working state according to the first requestmessage; and the injector manager injects the first scene operation into the first node, so that the first node detects whether the first node can work normally when the first scene operation is executed. The invention further provides a blockchain node detection device, computer equipment and a medium. A request message that the first node acquires the current service state is intercepted through an injector manager; the first scene operation is injected into the first node, so that the first node executes the first scene operation to obtain the current service state, the service state of the first node can be accurately regulated and controlled through the injector manager, and detection of the nodes in the blockchain is executed.

Description

technical field [0001] The present invention relates to the field of electronic technology, and more specifically, to a block chain node detection method, device, equipment and medium. Background technique [0002] Users can initiate transactions through the client, and all transaction information recorded in the transaction will be packaged into a block for storage. With the continuous expansion of transactions, each block is linked to each other to form a blockchain, which is also called a ledger. The blockchain is an open network ledger, and the blockchain can include multiple blocks (Block). Blockchain has many forms, for example, it can include public chain, private chain and alliance chain. [0003] The blockchain is composed of interconnected blocks, and a block is composed of multiple nodes with computing power. Since each node adopts a distributed algorithm, it is necessary to use a set of consensus algorithms to ensure consensus between each node, such as Practi...

In the prior art, node state switching is mainly triggered by controlling external resource abnormalities to realize the simulated detection of the blockchain, for example, by simulating network abnormalities, CPU abnormalities, or memory abnormalities. However, only external resource abnormalities are used to detect Triggering the switching of node status, it is difficult to accurately and clearly detect in which scenario the node is switching. For example, it is impossible to detect the result of an abnormal external resource, that is, the node is switching from the leader node to the follower node. Or switch from a follower node to a leader node
