Configuración del nodo


El archivo bitcoin.conf permite la personalización de su nodo. Cree un nuevo archivo en un editor de texto y guárdelo como bitcoin.conf en su directorio /bitcoin.

La ubicación de su directorio /bitcoin depende de su sistema operativo.

Windows XP C:\Documentos y configuración\<nombre de usuario>\Datos de aplicación\Bitcoin Windows Vista, 7, 10 C:\Usuarios\<nombre de usuario>\AppData\Roaming\Bitcoin Linux /home/<nombre de usuario>/.bitcoin Mac OSX /Usuarios/<nombre de usuario>/Biblioteca/Soporte de aplicaciones/Bitcoin
