[0037] refer to figure 1 As shown, the first embodiment of the present invention proposes a blockchain system based on node authority control. In this embodiment, the blockchain system 2 may include, but is not limited to, a plurality of first-type blockchain nodes 22 and at least one second-type blockchain node 24 that can communicate with each other through a blockchain network And at least one third type block chain node 26. It should be pointed out that, figure 1 Only the blockchain system 2 is shown with nodes 22-26, but it should be understood that greater or fewer components may alternatively be implemented.

[0038] In this embodiment, the first type blockchain node 22 may be a mining machine node, the second type blockchain node 24 may be an access node, and the third type blockchain node 24 may be an access node. Node 26 may be a wallet node. The wallet nodes include lightweight wallet nodes and full wallet nodes. Such as figure 2 Shown is a schematic diagram ...

[0045] refer to image 3 As shown, the second embodiment of the present invention proposes a blockchain node authority control method. In this embodiment, according to different requirements, image 3 The order of execution of the steps in the flowcharts shown may be changed, and certain steps may be omitted. The method includes the following steps:

[0046] Step S100, a first-type blockchain node 22 receives an access request from another blockchain node.

[0047] Specifically, the first type blockchain node 22 can establish a communication connection with other first type blockchain nodes 22 or second type blockchain nodes 24 via a blockchain network. When other blockchain nodes need to establish a communication connection with the first type blockchain node 22, an access request is sent to the first type blockchain node 22.

[0048] Step S102, the first-type blockchain node 22 determines the node type of the other blockchain nodes according to the first identifier in th...

[0058] refer to Figure 4 As shown, the third embodiment of the present invention proposes a blockchain node authority control method. In this embodiment, the steps S200-S210 of the blockchain node authority control method are similar to the steps S100-S110 of the second embodiment, the difference is that the method further includes steps S212-S224.

[0059] The method includes the following steps:

[0060] In step S200, a first-type blockchain node 22 receives an access request from another blockchain node.

[0061] Step S202, the first type blockchain node 22 determines the node type of the other blockchain nodes according to the first identifier in the saved first whitelist and the second identifier in the second whitelist. If the other blockchain nodes belong to the first type of blockchain nodes 22, step S204 is executed. If the other blockchain nodes belong to the second type of blockchain nodes 24, step S208 is executed.

[0062] Specifically, a first white list and...

Abstract

The invention discloses a blockchain node authority control method, which is applied to a blockchain system including first-type blockchain nodes, second-type blockchain nodes and third-type blockchain nodes. The method includes the following steps: after a first-type blockchain node receives an access request of another other blockchain node, determining a node type of the other blockchain node according to a first identifier in a first whitelist and a second identifier in a second whitelist; according to the node type, verifying whether the signature of the other blockchain node is legal byusing a first public key in the first whitelist or a second public key in the second whitelist respectively; and if the signature is legal, establishing a communication connection with the other blockchain node in response to the access request. The invention also provides a blockchain system and a storage medium. Thereby, the security of blockchain transaction data can be effectively guaranteed.

Description

technical field [0001] The invention relates to the technical field of block chains, in particular to a block chain node authority control method, a block chain system and a storage medium. Background technique [0002] Blockchain (Blockchain) technology has the characteristics of decentralization and information cannot be tampered with. Using blockchain technology can realize transaction events involving multiple parties (such as transfer transactions, payment transactions, etc.). For example, if Bank A and Bank B conduct a transaction on the blockchain, all other nodes on the blockchain will know the transaction, and other participants can participate in confirming the accuracy of the transaction to prevent information tampering. Furthermore, the blockchain is essentially a distributed database based on smart contracts, and the information on the blockchain will be shared to all nodes by the P2P (Peer-to-peer, peer-to-peer) network. [0003] However, in the existing block...
