### Hola, ya vamos por la tercer publicación para ir explicando de manera sencilla algunos términos y funcionamientos de Blockchain, en este caso estamos hablado y toando como ejemplo la de Bitcoin. <center>https://bitsapphire.com/wp-content/uploads/2017/09/What-Makes-a-Blockchain-Protocols-and-the-Future.gif</center> [Link](https://bitsapphire.com/wp-content/uploads/2017/09/What-Makes-a-Blockchain-Protocols-and-the-Future.gif) #### El "Hash" es una funcion matemática que encripta los datos de entrada sin importar su tamaño y devuelve como resultado datos de una cantidad fija. ## Veamos un ejemplo de uso comun de la función hash. En el caso de su utilización para almacenar contraseñas de un inicio de sesión, se escribe la contraseña y esta pasa por una función hash obteniendo una cadena de detos única e irrepetible. Entonces al momento hacer nuevamente un login, la contraseña ingresada pasa por el hash y el resultado obtenido se compara con el dato almacenado. De esta menera se hace difícil obtener la contraseña haciendo el procedimiento a la inversa, teniendo el Hash para obtener la contraseña. *********************************************** https://cdn.steemitimages.com/DQmPKrfRhAjZiEc3ZLV1APYeJCWnhrJDHYMpcyJTuwMECvH/image.png En la imagen de arriba podemos ver el hash en acción, también lo podes probar por ti mismo y así entender un poco mas. [Link para generar tu propio hash SHA256](https://passwordsgenerator.net/sha256-hash-generator/) ***************************** En el caso de la cadena de bloques de Bitcoin, esta función permite enlazar los bloques generados. ## Al proceso matemático para obtener un hash determinado que contenga una cantidad fija de ceros delante, se le llama "Proceso de minería". Conforme al poder de cómputo y cantidad de transacciones se determina cada cierta cantidad de bloque minados la dificultad, para que este proceso de generación de bloques se realice cada 10 minutos y su recompensa hoy es de 12.5 Btc. <center>http://i.imgur.com/UTfZ8QG.gif</center> [Link](http://i.imgur.com/UTfZ8QG.gif) ********************************** ### Muchas Gracias por leer, votar y compartir.

Gracias por la muy buena información creo que utilizado el Hash en todas nuestras cuentas se volvería mucho mas segura nuestra contraseña.Esperamos las siguientes lecciones
