Abstract

The invention is suitable for the technical field of distributed networks, and provides a consensus method of distributed node equipment, node equipment, a distributed network and a medium. The consensus method comprises the following steps: numbering transaction information sent by a client in a trusted execution environment, broadcasting the transaction information and the number value of the transaction information to each slave node device; submitting the transaction information when confirmation information for the number value returned by the first preset number of slave node devices is received; generating the confirmation information when the slave node equipment determines that the serial number value of the transaction information is not occupied by other transaction information; generating consensus information for the number value based on a first preset number of pieces of confirmation information in the trusted execution environment, and broadcasting the consensus information to each slave node device, wherein the consensus information is used for indicating the slave node equipment to submit the transaction information after the slave node equipment confirms that the consensus information is valid, the communication complexity is low, and the situation that nodes are disable in the consensus process can be avoided.

Description

technical field [0001] The present application belongs to the technical field of distributed networks, and in particular relates to a consensus method of distributed node devices, node devices, distributed networks and computer-readable storage media. Background technique [0002] The consensus algorithm is the basis for maintaining consistency between each node device in the distributed network. With the rapid development of distributed network technology, existing technologies have proposed different consensus algorithms for different distributed networks. For example, a Crash Fault Tolerance (CFT) consensus algorithm is proposed for a distributed network containing faulty nodes, and a Byzantine Fault Tolerance (Byzantine Fault Tolerance) consensus algorithm is proposed for a distributed network containing faulty nodes and malicious nodes. [0003] The consensus process and communication complexity between node devices corresponding to different consensus algorithms are d...
