specific Embodiment approach

[0037] There are four nodes A, B, C, and D in the blockchain network, and the simulated E node joins the blockchain network after obtaining a CA certificate offline.

[0038] Such as image 3Shown: First, E-node obtains ECert and RCert offline, then selects A-node as the introducer, configures the configuration file and starts it, A-node verifies the CA certificate of E-node and sends back the whole network connection information, E-node then Apply to establish a connection with the entire network node to join the consensus network. The existing four nodes pass the 2f+1 consensus authentication and then connect back to the E node. After confirming that N-f existing nodes have established a connection with themselves, the E node starts Recovery and waits for the Recovery to be completed. You can apply to join the blockchain network by broadcasting on the entire network.

Abstract

The invention discloses a dynamic node management method realized based on a BFT consensus algorithm. The management method comprises the following steps: a new node obtains the admission and participation consensus qualification of a block chain network through offline certificate acquisition on the block chain network, and requests the connection to the existing node of the whole network so as to successfully join in the consensus after the verification is passed; when requesting to exit the block chain network, one node requests the exiting to the whole network, and successfully exits the block chain network after each node administrator agrees the exiting. The specific step of newly adding the node is as follows: the new node acquires the connection information of the whole network after passing the introducer node connection by taking the CA certificate, and then joins in the block chain network through the whole network consensus and the accomplishment of the synchronization of the new node. The specific step of deleting the node is as follows: the node in opt-out broadcasts the exit request to the whole network, each node administrator agrees to the exiting and broadcasts the deletion of the exiting node to the whole network; when the whole network consensus agrees to the node exiting, the respective connection is updated, and the connection with the opt-out node is interrupted, and the node is cleared from the block chain network.

Description

technical field [0001] The invention relates to a decentralized blockchain CA certificate system, in particular to a dynamic node management method based on a BFT consensus algorithm. Background technique [0002] Blockchain technology, blockchain is a new type of decentralized protocol that can safely store digital currency transactions or other data, information cannot be forged and tampered with, and transaction confirmation on the blockchain is shared by all nodes on the blockchain Completed, the consensus algorithm guarantees its consistency. A public ledger is maintained on the blockchain. The public ledger is visible to any node on the storage block, thus ensuring that it cannot be forged and tampered with. [0003] The BFT consensus algorithm of the traditional blockchain does not have the function of dynamic node management. Although BFT has many improvements and variants, most of them are for the guarantee of consensus consistency and usability enhancement. The exp...
