區塊鏈將在接下來的幾十年中，繼網際網路、社群媒體、大數據、人工智慧之後，帶給人們重大的影響，它將會成為下一世代的網際網路，為社會、企業、個人帶來眾多好處。現今，人們仍仰賴具公信力的中間機構，如政府、銀行、大型公司等，來幫助建立信任關係。這些中間機構在各種交易與商業行為中扮演重要的角色。然而卻衍伸出許多問題。首先，中心化的架構容易被駭客攻擊；效率不佳，跨國轉帳將須好幾天的時間；之後還須支付不低的手續費給這些中間機構。區塊鏈將會是解決這些問題的最佳良藥。
在此篇論文中，為了解決現階段農業物聯網遇到的問題，我們設計並利用以太坊(Ethereum)實作了一個農業區塊鏈平台，其中包括建立以太坊網路，撰寫相關智能合約，建立一個分散式應用程式(Decentralized Application)。

In the next few decades, the blockchain will have a major impact on the Internet, social media, big data, and artificial intelligence. It will become the next generation of the Internet, for the society. , enterprises, individuals bring many benefits. Today, people still rely on credible intermediary institutions, such as governments, banks, and large companies, to help build trust. These intermediaries play an important role in various transactions and business practices. However, many problems have been extended. First, the centralized architecture is vulnerable to hacking; inefficient, cross-border transfers will take several days; then there will be a low fee for these intermediaries. Blockchain will be the best medicine to solve these problems.
In this paper, in order to solve the problems encountered in the current agricultural Internet of Things, we designed and used Ethereum to implement an agricultural blockchain platform, including the establishment of the Ethereum network, writing related smart contracts, and establishing a decentralized Application.
