Un nodo de Bitcoin es simplemente una computadora que ejecuta el programa de Bitcoin .

Lo más importante es que está conectado a otras computadoras (que ejecutan el mismo programa) para crear una red entre computadoras.

Un nodo tiene tres funciones:

Sigue las reglas
Comparte información
Conserva una copia de las transacciones confirmadas

Seguir las reglas

Cada nodo ha sido programado para seguir un conjunto de reglas. Al seguir estas reglas, un nodo puede verificar las transacciones que recibe y solo retransmitirlas si todo está correcto. Si hay algún problema, la transacción no se reenvía.

Compartir información

Es su trabajo principal, y la información que comparte a otros nodos son las transacciones .

Hay dos tipos de transacciones que comparten los nodos:

Transacciones nuevas : transacciones que ingresaron recientemente a la red.
Transacciones confirmadas : transacciones que se han "confirmado" y se han guardado en un archivo. Se comparten en bloques de transacciones (en lugar de individualmente).

Conservar una copia de las transacciones

Las transacciones nuevas van a la mempool hasta que quedan grabadas en la cadena de bloques, que es el almacenamiento permanente de las transacciones.

Cada nodo tiene una copia de la cadena de bloques para su custodia y la comparte con otros nodos si su copia no está actualizada.
