Example

[0036] First embodiment

[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, multiple first-type blockchain nodes 22 and at least one second-type blockchain node 24 that can be communicatively connected to each other through a blockchain network And at least one third type blockchain node 26. It should be pointed out that figure 1 Only the blockchain system 2 with nodes 22-26 is shown, but it should be understood that more or fewer components can be implemented instead.

[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 The node 26 may be a wallet node. The wallet nodes include lightweight wallet nodes and full wallet nodes. Such as figure 2 As shown, it is a schematic struct...

Example

[0044] Second embodiment

[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 needs, image 3 The execution order of the steps in the flowchart shown can be changed, and some steps can be omitted. The method includes the following steps:

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

[0047] Specifically, the first-type blockchain node 22 may establish a communication connection with other first-type blockchain nodes 22 or second-type blockchain nodes 24 through a blockchain network. When other blockchain nodes need to establish a communication connection with the first type blockchain node 22, they send an access request 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 stor...

Example

[0057] The third embodiment

[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, except 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 other blockchain node.

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

[0062] Specifically, a first white...

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...
