Embodiment 1

[0044] See figure 1 , figure 1 It is a schematic flow diagram of a warehouse construction method based on PBFT blockchain technology in an embodiment of the present invention.

[0045] Such as figure 1 As shown, a warehouse construction method based on PBFT blockchain technology, the method includes:

[0046] S11: Formulate a smart contract in the blockchain network, and elect each node in the blockchain network according to the smart contract, and obtain candidate nodes through the election;

[0047] In the specific implementation process of the present invention, the formulating a smart contract in the blockchain network includes formulating a smart contract in the blockchain, and pre-setting the system pass rate in the smart contract. It should be noted that the preset system pass rate is set to be greater than two-thirds.

[0048] Specifically, a smart contract is formulated in the blockchain network, and candidate nodes are elected according to the smart contract. After the smart...

Embodiment 2

[0061] See figure 2 , figure 2 It is a schematic flow diagram of a warehouse construction method based on PBFT blockchain technology in an embodiment of the present invention.

[0062] Such as figure 2 As shown, a warehouse construction system based on PBFT blockchain technology, the system is used in any one of the above-mentioned warehouse construction methods based on PBFT blockchain technology, the system includes: a network communication layer, a network entity Layer, network entity service layer, smart contract layer, public support components, security protection components, RPC API, Java SDK, blockchain application management layer, where the blockchain application management layer is the uppermost layer of the blockchain system, The blockchain application management layer is used to implement blockchain application and management.

[0063] Specifically, the public support component includes a log service component, a container management component, an exception handling...

Embodiment 3

[0072] The PBFT blockchain technology-based storage construction method and system provided by the embodiments of the present invention are suitable for the asset management of power grid companies. Among them, power grid companies are asset-intensive companies, and decentralized procurement leads to material reserves in various branch companies. The relatively closed material reserve information, geographic isolation and system barriers made it impossible to efficiently allocate materials among subsidiaries in emergency situations, resulting in high material inventories and slow turnover.

[0073] The embodiment of the present invention provides a storage construction method and system based on PBFT block chain technology to construct a material alliance network, build a platform, solidify smart contracts, continuously optimize and promote applications through block chain technology based on PBFT algorithm; The unified purchase and distribution of materials and Fed Reserves withi...

Abstract

The invention discloses a warehouse construction method and system based on a PBFT block chain technology, and the method comprises the steps that an intelligent contract is formulated in a block chain network, and a node is elected; other nodes vote the candidate nodes; a user signs a part needing consensus, sends the signed part to a network, broadcasts a consensus request, judges after receiving the consensus request by a certain node, rebroadcasts a transaction if the consensus request is met, and puts the transaction into a consensus cache sequence; after the system initializes consensus,the nodes enter a consensus process, a main node of the PBFT encapsulates and signs consensus information, the main node broadcasts the information in the whole network, and an auxiliary node judgesthe information; if the information is valid, a 'preparation' stage is entered, the information is packaged and signed, and the information is broadcasted to the whole network; and after the main nodedoes not respond within the specified time or has reached the consensus, view switching is performed to enter the next round of consensus to generate a new block. In the embodiment of the invention,the problems of opaque information, low safety performance and low throughput in the supply chain are effectively solved.

Description

Technical field [0001] The invention relates to the technical field of the power industry supply chain, in particular to a storage construction method and system based on PBFT blockchain technology. Background technique [0002] As an asset-intensive enterprise, one of the most important tasks of grid companies is to ensure the safe and stable operation of equipment assets. To ensure this important task, in addition to high-level operation and maintenance, a stable supply of spare parts and materials is also an important guarantee. In order to ensure production safety, all grassroots units have adopted a relatively conservative reserve strategy, and they have sufficient spare parts. The relatively conservative reserve strategy has brought about an ever-increasing reserve scale, which will lead to problems of opaque information, low security performance, and low throughput in the supply chain. Summary of the invention [0003] The purpose of the present invention is to overcome t...
