Abstract

Truffle is a framework for developing Ethereum decentralized applications. Currently, Truffle can not use server-side modules directly by adopting the webpack, a nodejs module bundling tool. To address this issue, in this paper, we propose a method to use the server-side modules based on the Ethereum event processing mechanism. In the proposed method, a separate node application with the nodejs module is added to execute the module in response to the request of the decentralized application. To this end, we introduce the notion of Function Gateway, a smart contract for connecting two applications with Ethereum's event-watch processing technique. In addition, we describe how to implement the emailing application associated with Ethereum based on the proposed technique.
