[0062] refer to figure 2 , figure 2 It is the first embodiment of the anti-attack method of the block chain super node of the present invention, and the anti-attack method of the block chain super node includes the following steps:

[0063] Step S10, determining a trusted node in the local area network where the super node is located, wherein the super node and the trusted node are in the same blockchain;

[0064] In the present invention, the execution subject is the anti-attack device of the block chain super node, which can be regarded as a node in the block chain.

[0065] The public chain community of the blockchain will select some blockchain addresses and generate a private key corresponding to the blockchain address. If a node in the blockchain contains a private key, it can be used as a super node of the blockchain. It should be noted that each node will vote on the blockchain address based on the public chain community to select the blockchain address correspondi...

Abstract

The present invention discloses an anti-attack method of a blockchain super node. The method comprises the following steps of: determining trusted nodes in a local area network where a super node is located, wherein the super node and the trusted node are located in the same blockchain; and disconnecting the point-to-point communication connection between the other nodes in the blockchain, and establishing the point-to-point communication connection between the trusted nodes, wherein the super node obtains and sends information through the trusted node. The present invention further disclosesan anti-attack device of a blockchain super node and a blockchain system. The blockchain information safety is high.

Description

technical field [0001] The present invention relates to the technical field of block chains, in particular to a block chain system and a block chain super node attack prevention method and device. Background technique [0002] Blockchain is a new application model of computer technologies such as distributed data storage, point-to-point transmission, consensus mechanism, and encryption algorithm. [0003] There are multiple nodes in the blockchain, and super nodes can be selected among these nodes. The super node is the basis for the stable operation of the blockchain network. If the IP of the super node is exposed, the super node will be vulnerable to network attacks, resulting in low information security of the blockchain. Contents of the invention [0004] The main purpose of the present invention is to provide a block chain system and a block chain super node attack prevention method and device, aiming at the problem of low information security of the block chain. ...
