 Yes, so I'm Darren Kjell CEO of Geo Directory and Geo Directory is an Irish-based company that provides location-based information on all the buildings in Ireland where they're located, what their function is, if they have a business, what type of business that business is mainly concerned with and our data is used by loads and loads of different companies to grow the intelligence that they have about their own customers to look for areas that they can develop into and also to ensure that when you know, an old adage in IT is rubbish in, rubbish out, so if very basic piece of information is in address, if you can get that right at the start and you build your your data models around that, it can be very powerful. So one of the roles that we do is help organizations to ensure they capture the address correctly. So I'm today, I'm talking at Predict and I'm going to be talking about blockchain. I'm going to be looking at blockchain from a case of several case studies, three of which based in Europe, in Georgia, Malta and Netherlands and then Geo Directory's own experience we're trying to introduce blockchain, its own blockchain into the insurance financial utility and telco sector and the challenges that we met and are faced with and then how those challenges are the same and may be different from those in the countries that I mentioned in Europe. Essentially what we're seeing is very while blockchain can be seen to deliver significant advantages, it's more in the back room effect and it hasn't been in a sense so dramatic that companies are going to jump into it. It's still a slow burner and it's a hard fight to get people to move to this new, it's no longer a new technology, but still relatively new idea for organizations to take on board. Yeah, so while we have built, we have actually built our own blockchain and we've also developed a whole suite of tools to help organizations and to help organizations manage their data, mind their data and bring greater value to data. So we have a tool that enables you to clean your addresses, legacy addresses and then also append various pieces of information that will enhance the ability for you to use that data. We have APIs that enable you to capture the data first time right every time which again means you can trust in your data and build your analytics from that. And then we have whole series of new data sets come in through directory which will enable you to, for example, if you're selling solar panels, be able to decide which house is going to get delivered the best value without ever having to visit it. So from the top of the roof to the bottom of the floor, we'll be able to help organizations understand what's in the area, how they can work with it and how they can best deliver their services.
