What is a Node?
A node in the Bitcoin context is an internet connected computer that is running the Bitcoin software.
It communicates with other bitcoin nodes and forms a network.
All bitcoin transactions take place on this network, and all nodes have access to all transactions.
Should I run a node?
The short answer is yes, the long answer is that you will do it at a certain point in your bitcoin journey, if you decide to stick around.
There’s an argument that you aren’t really using bitcoin unless you are running one.
