Análisis y desarrollo de una aplicación de registro de permisos y ausentismos sobre una Blockchain mediante un Smart Contract desplegado en una testnet de Ethereum

Abstract

The project carried on consists of developing a decentralized application (DApp), which allows the registration of presences and absences, for its implementation tools such as Ethereum Blockchain and Smart Contracts were used, technologies oriented to Web 3.0 that offer numerous benefits, as security, decentralization of information and transactionality between different without the need for intermediaries, allowing the information stored in the Blockchain to be transparent to the user and in turn become in immutable.
