Embodiment Construction

[0037] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0038] The solution of the embodiment of the present invention is mainly as follows: when a transaction request for node change is received in the blockchain network, the node first packs the transaction request into a block, and then the consensus module and the network module compare the block Networking and consensus are carried out so that each node in the blockchain network can obtain the block, and then each node executes the transaction process of the block in the virtual machine, so as to trigger the frame callback of the contract according to the executed transaction process, Finally, the contract-based framework callback updates the node configuration list to change nodes in the node configuration list, thereby realizing the dynamic change of nodes in the blockchain network. In order to solve the relatively ...

Abstract

The invention discloses a block chain node dynamic change method, a system thereof and a computer readable storage medium, wherein the method comprises the following steps that: when receiving a transaction request of a node change in a block chain network, the nodes package the transaction request into a block; a consensus module and a network module perform consensus and networking to the blockto enable each node in the block chain network to obtain the block; the nodes respectively execute the transaction process of the block in the virtual machine to trigger a framework callback of a contract based on the executed transaction process; and a node configuration list is updated based on the framework callback of the contract to change the nodes in the node configuration list. The invention is capable of realizing dynamic change of the nodes in all types of block chains, so that the change scenario of the nodes is richer and the change mode is more flexible.

Description

technical field [0001] The present invention relates to the technical field of block chains, in particular to a method, system and computer-readable storage medium for dynamically changing block chain nodes. Background technique [0002] The existing blockchain node consensus methods mainly include Proof Of Work (POW), Proof of Stake (POS), Delegated Proof of Stake (DPOS) and available Byzantine Fault Tolerance (Practical Byzantine Fault Tolerance, PBFT) and other algorithms. [0003] Among them, the PBFT algorithm does not support the dynamic change of nodes. The joining and exit of nodes requires the termination of services to modify the global configuration, and the way of changing nodes is relatively limited. However, POW, POS and DPOS algorithms, although they can dynamically change nodes, are only applicable to public chain scenarios, not consortium chain scenarios, and the dynamic change scenarios of nodes are relatively limited. Contents of the invention [0004]...
