HotelSys/CryptoStay es un MVP de gestión hotelera y pagos híbridos que integra un backend Web2 con base de datos MySQL y una capa Web3 para cobros con criptomonedas. En la parte Web2, el sistema permite administrar el hotel: crear y editar habitaciones (tipo, descripción, precio en COP), subir y asociar fotos, controlar estados operativos (disponible/ocupada/limpieza) y gestionar reservas (creación, consulta, cancelación y seguimiento del estado de pago). El acceso se maneja por roles (administrador, gerente, aseo y huésped), lo que define qué funcionalidades ve cada usuario. Para el huésped, la aplicación incluye un panel con “IA-lite” que aprende gustos de forma simple: el usuario puede indicar preferencias (tipo de viaje, presupuesto, tipo de habitación y amenidades) y el sistema también registra señales de comportamiento como las habitaciones que consulta. Con estos datos, se generan recomendaciones personalizadas con razones claras (por ejemplo, “Habitación destacada”, “Coincide con tu presupuesto” o “Has visto esta habitación varias veces”) para mejorar la conversión. En la capa Web3, el pago se realiza con MetaMask sobre una red local (Hardhat) usando ETH o un token de prueba tipo USDC. El flujo recomendado es: primero se crea una reserva “pendiente” en Web2 y luego se paga en Web3 indicando el ID de la reserva. Tras la transacción, el sistema captura el txHash, consulta el receipt en el RPC local y verifica que exista el evento de pago correspondiente a esa reserva en el contrato. Si la verificación es correcta, la reserva se marca como “pagada” en MySQL y el txHash queda guardado como evidencia auditable. Esta arquitectura demuestra cómo un sistema tradicional puede incorporar cobros en blockchain manteniendo control, trazabilidad y experiencia de usuario.
