As an analogy, RPC works as a function call. Like a function call, when an RPC is made, the calling arguments are passed to the remote machine and the caller waits for a response to be returned from the remote machine.The client machine makes a procedure call that sends a request which included program number, version number, procedure number & etc to the server and waits. The thread is blocked from processing until either a reply is received, or it times out. When the request arrives, the remote machine calls a dispatch routine that performs the requested service, and sends the reply back to the client procedure. After the RPC call is completed, the client program continues.
Good to know. Thanks a lot mate for this useful explanation about RPC calls. With this, I would be able to make my own Bitcoin apps that would use Bitcoin's functions like creating multi-sig addresses, viewing peer stats, and more. It would be more of like an RPG game where it pays you satoshi after a minimum amount has been reached. You could also choose to buy upgrades for your character, and many more using Bitcoin.
Basically, I find Python a lot easier for this but I would also look into making an online wallet for an altcoin, as most alts have the same RPC commands as Bitcoin.
