step S2: the core node set is provided with one and only current leader node; the prior leader node periodically broadcasts announcement information about the core node set to all other core nodes so that all core nodes maintain the same core node set information;

step S3: the current leader node selects a core node which meets the set constraint condition as an alternative node; other core nodes except the prior leader node and the alternative node are candidate nodes;

the prior leader node broadcasts alternative node information to all other core nodes, and the core node selected as the alternative node sets the self state as the alternative state;

the candidate node continuously keeps the candidate state of a new leader in the permission chain after the candidate node is prepared to take part in the election of the consensus algorithm leader of the existing leader node;

step S4: when the prior leader detects that the preset period expires, sending a switching message to the alternative node; the alternative node receives the switching message and sends switching confirmation information to the current leader node, the current leader node is converted into a candidate node, the alternative node is converted into a new leader node, and the new leader node sends leader announcement information to all the candidate nodes; the new leader node selects a new alternative node according to the step S3;

step S5: if an abnormal event occurs and the alternative node cannot receive the announcement message of the current leader node within a certain time, the alternative node is automatically switched into a new leader node; the new leader node sends leader announcement information to all candidate nodes; the new leader node selects a new candidate node according to step S3;

step S6: the candidate nodes continuously monitor the announcement information of the current leader node and the alternative nodes in the permission chain, if the announcement information of the current leader node and the alternative nodes is not monitored in the set time, one or more candidate nodes change the self state into the participation state and further change the self state into the participation node;

step S7: the method comprises the steps that a participating node broadcasts own election declaration to other core nodes in a permission chain, wherein the election declaration is an advertisement message comprising node capacity and node state, and the permission chain selects a new leader node from the participating node;

any core node receiving the election declaration checks whether one election node is suitable to become a leader node or not according to a preset strategy or rule, or checks which election node is more suitable to become the leader node, and then replies confirmation information supporting the election of the node to each election node, or replies rejection information not supporting the election of the node to each election node, or replies voting support to all the election nodes to become the new leader node;

if one candidate node receives the confirmation information of more than 2/3 core nodes in the candidate node set, the candidate node is automatically converted into a leader state and becomes a new leader node, and the dropped candidate node automatically converts the self state into a candidate state and back into a candidate node;

the new leader node checks the current core node set information, announces the core node set information according to step S2, and selects an alternative node according to step S3.

Wherein, the constraint conditions are set as follows: and selecting the core node ranked at the first position as the alternative node according to a preset strategy or rule. Such as priority order, weighted queuing, or derived function results from node capability information. The node capability includes CPU speed, memory size or storage space size, etc.
