Embodiment 1
[0096] Please refer to figure 1 , Embodiment 1 of the present invention is:
[0097] The present invention provides a block chain heterogeneous consensus method with high security, comprising the following steps:
[0098] S0: preset first attribute list A={A 1 ,A 2 ,A 3}, that is, three attribute identification values A are preset in the first attribute list A 1 ,A 2 ,A 3 ;Default second property list B={B 1 ,B 2 ,B 3}, that is, the preset three attribute identification values B in the second attribute list B 1 ,B 2 ,B 3 ;
[0099] Determine whether there is a newly added node in the blockchain, and if so, assign an identification value from A and B to obtain the first identification value and the second identification value; according to the first identification value and the second identification value, all The above-mentioned newly added nodes are assigned to the slices with corresponding serial numbers;
[0100] The identity value of the attribute is A 1...
Embodiment 2
[0134] Please refer to figure 2 , the second embodiment of the present invention is:
[0135]The present invention provides a block chain heterogeneous consensus terminal with high security, including a memory, a processor, and a computer program stored on the memory and operable on the processor, when the processor executes the computer program Implement the following steps:
[0136] S0: preset first attribute list A={A 1 ,A 2 ,A 3}, that is, three attribute identification values A are preset in the first attribute list A 1 ,A 2 ,A 3 ;Default second property list B={B 1 ,B 2 ,B 3}, that is, the preset three attribute identification values B in the second attribute list B 1 ,B 2 ,B 3 ;
[0137] Determine whether there is a newly added node in the blockchain, and if so, assign an identification value from A and B to obtain the first identification value and the second identification value; according to the first identification value and the second identificati...

Abstract
The invention provides a block chain heterogeneous consensus method with high safety and a terminal. In each round of consensus, The first decision node of the block is screened out by screening out the decision nodes of each slice, and the sub-message blocks generated by the decision nodes corresponding to the slice are verified by the nodes in the slice. The first decision node receives the sub-message blocks only after the sub-message blocks are divided into slices and no less than a preset number of nodes are verified to pass the blocks. And the sub-message blocks sent by the decision nodes of each slice is verified by the decision nodes, and the verified sub-message blocks is merged to obtain the merged message blocks, and the message blocks are sent to the decision nodes of each slice for verifying respectively, when the number of verified sub-message blocks is greater than a preset number threshold value, indicating that the message blocks are verified to be passed; The invention solves the problem that when a hacker attacks a node of a slice in a block chain, the block decision-making is seriously faulted, and the safety of the block chain is improved.
Description
technical field [0001] The invention relates to the technical field of block chains, in particular to a block chain heterogeneous consensus method and terminal with high security. Background technique [0002] The consensus mechanism is one of the core technologies of blockchain. The consensus mechanism is a mechanism for users who do not trust each other to reach trust in the blockchain, and it is the basis for record transmission, verification, and replication in the blockchain. The current consensus mechanism mainly includes Proof of Work (PoW), Proof of Stake (PoS), Delegated Proof of Stake (DPoS) and Practical Byzantine Fault Tolerance (PBFT) And the deformation of these 4 consensus mechanisms. Of course, the new distributed ledger technology, such as the new distributed ledger technology represented by Directed Acyclic Graph (DAG), has its own consensus mechanism. Existing consensus mechanisms are more or less problematic. For example, the PoW consensus mechanism h...
