This sets the Bitcoin node’s administrative (RPC) credentials used to control the server itself.<br /><br />
|
||
Keep these private — they grant full access to your node.<br /><br />
|
||
These credentials are <b>not</b> used by miners to connect; miners only need your Bitcoin address and can use any password.
