En este capítulo vamos a configurar todas las herramientas necesarias para el desarrollo de contratos inteligentes. Empezaremos instalando un cliente Ethereum, que es un software que se puede utilizar para interactuar con la blockchain de Ethereum. A continuación, instalaremos Node.js, que proporciona el entorno JavaScript para Truffle. Por último, instalaremos Truffle y Ganache de la Suite Truffle. Truffle proporciona un fantástico conjunto de utilidades utilizadas para probar e implementar nuestros contratos, mientras que Ganache nos proporciona un entorno local de blockchain para ejecutar nuestra aplicación localmente.
Una vez instaladas estas herramientas, estaremos listos para escribir nuestro primer contrato inteligente. Sin más preámbulos, empecemos.
