+#welcome
+welcome.title=Bienvenido a Sparrow
+welcome.step1.introduction=Introducción
+welcome.step1.label1=Sparrow es una billetera de Bitcoin con un enfoque en la seguridad y la facilidad de uso.
+welcome.step1.label2=Sparrow puede operar tanto en modo en línea como fuera de línea. En el modo en línea, se conecta a un servidor para mostrar el historial de transacciones. En el modo fuera de línea, es útil como editor de transacciones y como coordinador multisig desconectado.
+welcome.step1.label3=La barra de estado en la parte inferior muestra el estado de la conexión, como se muestra a continuación:
+welcome.step2.introduction=Conexión a un servidor público
+welcome.step2.label1=Si estás comenzando tu camino en la auto custodia o solo almacenando una pequeña cantidad, la forma más fácil de conectar Sparrow a la blockchain de Bitcoin es a través de uno de los servidores públicos de Electrum preconfigurados.
+welcome.step2.label2=Sin embargo, aunque Sparrow solo se conecta a servidores que tienen un historial de respetar la privacidad, aún no es lo ideal ya que estás compartiendo tu historial de transacciones y tu saldo con ellos.
+welcome.step2.label3=Un interruptor amarillo significa que estás conectado a un servidor público.
+welcome.step3.introduction=Conexión a un nodo de Bitcoin Core
+welcome.step3.label1=Si estás ejecutando tu propio nodo de Bitcoin Core, puedes configurar Sparrow para que se conecte directamente a él.
+welcome.step3.label2=Esto significa que no estás compartiendo tus datos de transacciones, pero ten en cuenta que Bitcoin Core almacena tu saldo, transacciones y claves públicas sin cifrar en ese nodo, lo cual no es ideal para un almacenamiento en frío verdadero.
+welcome.step3.label3=Un interruptor verde significa que estás conectado a un nodo de Bitcoin Core.
+welcome.step4.introduction=Conexión a un servidor privado de Electrum
+welcome.step4.label1=La forma más privada de conectarse es a tu propio servidor de Electrum, que a su vez se conecta a tu nodo de Bitcoin Core.
+welcome.step4.label2=Dado que estos servidores indexan todas las transacciones de Bitcoin por igual, las transacciones de tu billetera nunca se almacenan en el servidor de manera identificable, y tu servidor olvida tus solicitudes inmediatamente después de servirlas.
+welcome.step4.label3=Un interruptor azul significa que estás conectado a un servidor privado de Electrum. ¡Ahora estás listo para configurar un servidor y empezar a usar Sparrow!
+welcome.offline=Desconectado
+welcome.offline.tooltip=Sólo demostración - ¡no estás conectado!
