Web3j

Web3j es una biblioteca de Java y Android diseñada para integrar aplicaciones con clientes de blockchain de Ethereum. Proporciona un cliente JSON-RPC para leer datos de la cadena y enviar transacciones, un generador de wrappers de contratos inteligentes que crea código Java nativo a partir de definiciones de contratos, y un gestor de billetera programático para manejar claves criptográficas y firmar transacciones.

El proyecto se distingue por un sistema de generación de wrappers basado en plantillas que permite una interacción segura con tipos con contratos on-chain. También incluye un conjunto de herramientas dedicado para traducir nombres de dominio legibles por humanos en direcciones criptográficas mediante resolución de servicios de nombres.

La biblioteca cubre una amplia gama de capacidades, incluyendo ejecución asíncrona para consultas de blockchain, gestión de claves criptográficas y depuración de ejecución de máquinas virtuales para analizar el comportamiento de los contratos. Además, proporciona un modelo de conexión basado en proveedores para abstraer el transporte de red y herramientas de línea de comandos para el arranque de proyectos.
