 One of the reasons I started IOHK was because I believe that experimentation is the mother of discovery. So I wanted to see more experimentation with blockchains and its related technologies. So one of the things that we can do at IOHK is we can bring on the people who know about these technologies and we can bring on the people who can implement and experiment with these technologies. Charles has an amazing ability to find collaboration and partnership. His mind just naturally thinks, what can we do, what can they do, how can we both benefit. I'm always amazed at the opportunities he finds between people. My mind doesn't always think that way, I don't always see all the possibilities of collaboration or partnership. And in that respect I love working with Charles because he brings people together. We were asked to do a new blockchain and it being 2015, we got to look at all the other blockchains and we got to look and see what's working, what's not working and what would be exciting to do in the future. So Bitcoin is a value chain, what we call a value chain, it has a token, it's scarce, it's immutable, you can't double spend, people can transfer and you can make payments with that. Ethereum, on the other hand, has a smart contracting layer, so you can do programmable money. This is very exciting, you can do a lot of interesting things with smart contracting, however they also have the value token inside of that blockchain. So we decided maybe it would not be so wise to couple the computational layer with the value layer. So we're working on a system now that's going to have multiple layers, the first one is the value chain with the value token and the second chain would be the computational layer.
