Extensible and secure consensus method and system, storage medium and intelligent terminal

Abstract

The invention belongs to the technical field of a distributed system consensus mechanism and a block chain public chain, and discloses an extensible and secure consensus method and system, a storage medium and an intelligent terminal, comprising three protocols of node registration, block generation and block synchronization; according to a node registration protocol, a new node generates initial information and initialized right information, generates a node registration transaction by using public information and right information, and then sends the node registration transaction to a consensus network for node registration to become a network node; according to a block generation protocol, a consensus node generates a node right share table and a random number to perform candidate election, then a candidate generates compressed candidate blocks and broadcasts the compressed candidate blocks, and other nodes verify candidate block information and then select the candidate blocks meeting conditions as leaders to generate blocks; according to the block synchronization protocol, an unsynchronized node calculates a current consensus round and verifies the legality of a received chain, and a chain is selected for synchronization by using a chain selection rule. The security attribute of the scheme is improved, and the expandability of the scheme is effectively improved.

Description

technical field [0001] The invention belongs to the field of distributed system consensus mechanism and block chain public chain technology, and in particular relates to an expandable and safe consensus method, system, storage medium, and intelligent terminal. Background technique [0002] Currently: Blockchain technology is a brand-new distributed infrastructure and computing paradigm built on a distributed peer-to-peer network, using chained data structures, consensus algorithms, cryptography and automated smart contracts to store and manage data , and ensure data security. The public chain is a blockchain network that does not require permission and has a large number of nodes. It has excellent features such as decentralization and trustlessness. Technical advantages. [0003] The consensus mechanism of a distributed system is an agreement and a solution for reaching a consensus on a certain problem among multiple peer nodes. The traditional distributed system consensu...

Problems solved by technology

[0007](1) The existing Ouroboros consensus scheme mainly focuses on the security of the public chain consensus scheme. The protocol also introduces an accurate clock for block generation to achieve cost higher

[0008](2) The existing Ouroboros does not consider the scalability of the scheme and the impact of the equity mechanism on the consensus scheme, making the scheme unsuitable for the actual situation of increasing performance requirements Application Scenario

[0009](3) The specific implementation of the existing Cardano requires more than a certain percentage of nodes to participate in the consensus, which actually violates the decentralized nature of the blockchain, making Cardano cannot fully become a decentralized public chain system

[0010]The difficulty of solving the above problems and defects is: it is difficult to reduce the solution’s dependence on third parties such as the global clock while ensuring the security of the solution; the design is complete and feasible with high scalability The new consensus scheme needs to consider many factors; the decentralized public chain system needs to balance the functions and functions of each node, and there are difficulties in system design
