Blockchain-Secured AI AgriChat Platform

Increasing fear of data privacy, security, and cen- tralization in traditional messaging applications calls for an alternative provided by decentralized applications. This paper presents the design and implementation of a decentralized chat application built on the Ethereum blockchain. Using Smart Contract in developing in Solidity, Hardhat as development framework, and MetaMask wallet in authentication methods, the application ensures safe communication that is immutable. The front-end is implemented into React.js, and interoperability with the Ethereum network for the back-end services has been facilitated using Node.js. Every communication that is sent out and received by the users is securely stored on the blockchain to prevent data interference by outsiders and ensure integrity. The result is a privacy-focused messaging platform that highlights the potential of blockchain technology to the redesign of digital com- munication. Future development aims to integrate Agricultural Assistance Chatbot for farmers, providing recommendations on sustainable techniques for farming and optimizing resource use for minimum environmental damage. This will improve the platform allowing mass users to make informed choices that will lead to productivity and sustainability in agriculture.
