Problems solved by technology

[0003] At present, the HTTP protocol (Hypertext Transfer Protocol) is the most widely used network protocol in the Internet. It can ensure that the computer can transmit hypertext documents correctly and quickly, but because the protocol is centralized, it means that all data are stored On the centralized server, once the server is down, users will not be able to obtain resources

Embodiment Construction

[0038] Attached below Figure 1-5 To further explain this issue:

[0039] The present invention provides a method for reaching a standard consensus between enterprises based on blockchain and IPFS. The blockchain architecture design is as follows: figure 2 shown. System flow chart such as image 3 As shown, first collect the standard file to the local computer, then upload the file to the front page of the Dapp and initiate a vote. After receiving the notification, other companies complete the vote within the specified time, and judge whether the vote is passed through the smart contract. If the vote is passed, then Upload the result to the blockchain, and save the blockchain transaction address, and automatically upload the standard file to IPFS, calculate the hash value of the file, upload it to the blockchain node, synchronize to other nodes, and save the blockchain transaction address. Dapp query flow chart such as Figure 4 , first select the query information, and ...

Abstract

The invention discloses an inter-enterprise standard consensus method based on a block chain and an IPFS (InterPlanetary File System), capable of well combining the block chain and the IPFS, improvingthe consensus efficiency of enterprises and ensuring the security of standard files on the premise of trust. An alliance chain in the block chain can bind all enterprises to form an alliance, and a Dapp decentralization application is built on the alliance chain, and all nodes of the block chain can vote in the Dapp, and interaction between a foreground page and the block chain can be safely andreliably achieved through an intelligent contract, and text data storage, query and other operations are conducted; on this basis, in combination with an IPFS, the standard file can be safely and credibly stored in the blockchain after each enterprise reaches a consensus; and finally, each enterprise can safely and effectively reach a certain standard consensus on line.

Description

technical field [0001] The invention belongs to the technical field of blockchain, the field of data security, and the field of file security. Background technique [0002] Digital currency - "Bitcoin" is a digital encrypted currency for point-to-point transmission. Use blockchain technology to deal with transaction issues. With the continuous development of "Bitcoin", the blockchain technology has also been continuously improved. On this basis, the underlying technology of the blockchain has been extracted, resulting in an open source blockchain platform - Ethereum. Ethereum uses blockchain technology to solve various problems through smart contracts. The emergence of Ethereum has set off a new round of blockchain technology climax. Users can develop decentralized applications on Ethereum, referred to as Dapp applications. Dapp applications use blockchain technology as the bottom layer and realize front-end data through smart contracts. Interaction with blockchain. [0...
