Problems solved by technology

[0005] In the PoW consensus, an irreversible block takes about 60 minutes; in the DPoS consensus, it also takes about 10 minutes. Such a long block confirmation time makes the data storage delay too long, which greatly affects the user's use of the blockchain. System experience

Abstract

The embodiment of the invention provides a food data storage method and device based on a block chain. The method comprises the following steps that: a storage node receives a service data storage request from user equipment, wherein the service data storage request comprises food data to be stored; the storage node stores the to-be-stored food data and sends a storage certificate to the user equipment after the storage is completed; the storage node sends the storage proof to the block output node; and the block output node records the storage proof in a block chain, so that the user equipment confirms the authenticity of the stored food data to be stored through the block chain after a preset time. Therefore, the real-time storage of the service data is realized, the storage delay of thedata is reduced, and the user experience is improved.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a method and device for storing food data based on blockchain. Background technique [0002] Blockchain technology, also known as distributed ledger technology, is an Internet database technology, which is characterized by decentralization, openness and transparency, allowing everyone to participate in database records. [0003] If we assume that the database is a ledger, reading and writing the database can be regarded as an act of bookkeeping. The principle of blockchain technology is to find the fastest and best person for bookkeeping within a period of time, and this person will keep the bookkeeping. account, and then send this page of information to everyone else in the system. This is equivalent to changing all the records in the database and sending them to every other node in the whole network, so blockchain technology is also called distributed ledger. [0004] At pr...
