Embodiment Construction

[0059] In the following description, in order to illustrate the solution of the present invention rather than limit it, specific details such as specific system structures and technologies are presented for a thorough understanding of the embodiments of the present invention. It will be apparent, however, to one skilled in the art that the present application may be practiced in other embodiments without these specific details. In other instances, detailed descriptions of well-known systems, devices, circuits, and methods are omitted so as not to obscure the description of the present invention with unnecessary detail.

[0060] The purpose of the present invention is to propose a safe and superviseable rights and interests proof method under the fragmented blockchain to solve the problems of non-interest, long-range and 51% attacks in PoS in the existing fragmented blockchain. The consortium chain supervision agent performs public chain node identity authentication and grants ...

Abstract

The invention discloses a safe and supervisible right proving method and system under a fragmented block chain. The method comprises the following steps: a new node requests to join a public chain, and a supervision server in a supervision alliance chain authorizes a block chain to register a certificate to authenticate the identity of the node; a user initiates a transaction, a supervision agent in a supervision alliance chain verifies the transaction, a consistency protocol based on PBFT is utilized to achieve a consistency sequence of effective transactions, and the transaction sequence is sent to a fragmented public chain network; the supervision agent and the public chain node conform to the transaction sequence and correctness by using a consistency protocol based on PBFT and a right proving mechanism based on hardware, and store the transaction content in the supervision alliance chain and the public chain; the hardware module executes final transaction confirmation by using a counter of the random number generator to realize transaction transfer; and malicious public chain nodes with no interest relationship are supervised by using transaction retrieval. According to the invention, node supervision under the distributed block chain system is realized, and safe and reliable right proof under the fragmented block chain is realized.

Description

technical field [0001] The invention belongs to the field of information technology, and specifically relates to a method and system for proving rights and interests that are safe and supervised under the fragmented blockchain, which can be used in combination with the Byzantine Protocol (BFT) and the consensus mechanism under the fragmented blockchain to safely realize the public domain The block chain network exchanges information sequence and correctness. Background technique [0002] As a decentralized technology, the blockchain system is promoted and maintained by all network nodes using the blockchain protocol without any third-party participation. Blockchain protocols have been extensively studied to invent consensus mechanisms to improve the security of blockchain consensus and the scalability of blockchain systems. Although some consensus mechanisms have been proposed (such as Proof of Elapsed Time, Proof of Trust, Ouroboros, Proof of Stake (PoS), Algorand, etc.), ...
