| Summary: | 碩士 === 國立暨南國際大學 === 資訊工程學系 === 107 === With the advent of cryptocurrency, Bitcoin has become a hot topic. Blockchain, the core
technology behind Bitcoin, has gradually been valued. In recent years, we often see the
collapse of agricultural prices in the news. One of the main reasons is that the agricultural
information between farmers is not transparent. Large-scale planting of fruits and
vegetables in the current season results in an oversupply market environment. If we
provide a platform for information sharing of agriculture, we believe that we can reduce
the possibility of price collapse. Therefore, we propose a method of information sharing
of agriculture by the blockchain technology in this thesis, and we also propose a credit
value mechanism to judge whether the information provided by the user is trustworthy.
This thesis assumes that each person has a set of public and private keys. The credit value
is bound to the public key. We judge whether the agriculture information provided by the
user is credible through a mechanism to cross-validate the transaction records of sales and
purchases. Once blocks have been added to the blockchain, the contents of the block
cannot be modified. Thus, we can trace the past records easily.
