Bitcoin core 0.11.2 (bitcoind --help) prints the following:
-blocknotify=<cmd>
Execute command when the best block changes (%s in cmd is replaced by
block hash)
I was wondering what this "best block" would be, but funny: I did not find anything about it in the internet.
So does anyone know what this 'best block' is?
Why should one use the notification for it? I enabled it to notify me via email, but it spams, so I disabled it.
