In Aleo, full nodes run a JSON-RPC server to enable API calls for fetching data and interacting with peers connected to the network.
-rpc-port 3030
The default RPC port is 3030. This can be specified with the -rpc-port
flag when starting a full node.
-rpc-username {USERNAME} -rpc-password {PASSWORD}
The RPC server exposes protected RPC endpoints for account specific operations, such as creating an account, creating a transaction, and fetching record commitments. RPC requests to protected RPC endpoints can be optionally guarded with an authentication header.
To enable this authentication layer, provide the authentication credentials to
the -rpc-username
and -rpc-password
flags when booting up a full node.
