The Substrate Node Template says in the "Run" section of the README, that the single-node development chain will start with "non-persistent state" if run with the following command:
cargo run --release --dev --tmp
The Substrate Node's --help
file says --dev
specifies the development chain and sets, among other things, the --tmp
flag.
But, what is --tmp
is supposed to do? The node seems to run fine with only --dev
. I can't find --tmp
in --help
either.
Also, if --help
is accurate, then the --tmp
doesn't need to be specified alongside --dev
, and that may just be a mistake in the README?
