I have recently upgraded my
bitcoind node to
v0.13.0 and encrypted a new HD wallet:
$ bitcoin-cli getwalletinfo
I am getting some
hdmasterkeyid hexadecimal number displayed on the screen. I have not yet done my homework on HD wallets and reading the relevant sections of 'Mastering Bitcoin' does not alleviate my fear: should I be worried about
hdmasterkeyid being displayed on my screen? how sensitive is this number? I am guessing this is safe (as no password authentication is required to get this number) but I would like to make sure this is the case.
