If you make things too implicit, you invite all kinds of DOS attacks where you get tricked into wasting resources. -John -- Mailing list: https://launchpad.net/~mimblewimble Post to : mimblewimble@lists.launchpad.net Unsubscribe : https://launchpad.net/~mimblewimble More help : https://help.launchpad.net/ListHelp
