A quick wikipedia search shows: RPC: Remote procedure call (RPC) is an Inter-process communication technology that allows a computer program to cause a subroutine or procedure to execute in another address space (commonly on another computer on a shared network) without the programmer XML-RPC (short for Extensible Markup Language remote procedure call) is a protocol specification for executing RPC calls (remote calls in computer networks) using the stateless network protocol HTTP and the markup language XML, which gives it part of its name. Learn how to install IceRPC and write your first IceRPC application. Note: When you get free ZEN from the Horizen Faucet, you are actually receiving TZEN, as it is required for the Gobi Testnet network.
