### The JSON-RPC interface
|

* the JSON-RPC API is an interface that allows us to write programs that use an Ethereum client as a gateway to an Ethereum network and blockchain.
|
|
* the RPC interface is offered as an HTTP service on port 8545. For security reasons it is restricted, by default, to only accept connections from localhost.
