What do you use for username

What do you add for username?
“rpcuser=username” >>~/.zcash/zcash.conf

Also does this:
head -c 32 /dev/urandom | base64"

Generate a random password for you?

mkdir -p ~/.zcash
echo “addnode=mainnet.z.cash” >~/.zcash/zcash.conf
echo “rpcuser=username” >>~/.zcash/zcash.conf
echo “rpcpassword=head -c 32 /dev/urandom | base64” >>~/.zcash/zcash.conf


It really doesn’t matter (only matters if you are using RPC interface and wish to connect to it) and yes you just need a random rpcpassword and that code will generate you one (but can be anything that is strong). See this https://github.com/zcash/zcash/blob/master/doc/security-warnings.md#rpc-interface

So where do the blocks go per say, like how do I see them without a wallet for zcash yet?

And thanks!
