 Quick question in your view. There's a lot of talk out there regarding Bitcoin and blockchain. What is the difference in your view between Bitcoin and blockchain? How are they similar? How are they different? Blockchain is one of the foundational technologies that was invented at the same time, by the same person or persons for Bitcoin. In a desperate attempt to co-opt, embrace, and extend this technology, many of the companies and governments out there, who are really looking at opportunities to create centralized versions of this, and are missing the fundamental point, which is decentralization, are grasping on this blockchain technology and trying to circle the square, trying to change this. So there's a bit of bargaining going on. When I say bargaining, I'm referring to the five stages of grief. The response to Bitcoin has been denial, anger, and now we're in bargaining. The bargaining stage is, yes, Bitcoin, but not Bitcoin. How about blockchain without the currency? That represents a fundamental failure to understand what is the real value proposition here. The real value proposition is a decentralized system. The decentralized system itself only works if control over it is decentralized, and that only works if there is a mechanism by which the network can be secured. That mechanism is a competition based on game theory that involves miners, as they're known. Don't worry about what that means. What they're doing is competing by staking a currency, Bitcoin in this case, or any of the other digital currencies, and using that to guarantee that they're going to follow the security rules. If they follow the security rules, they get rewarded in the intrinsic currency of the network. If they don't follow the security rules, they lose the investment they've made in electricity or in the currency they've staked. That mechanism is at the heart of making the system secure. Without a currency, you can't do the security. Without a currency, you have to have a central authority that decides if a transaction should be included or not. At that moment, it is no longer borderless. It is no longer censorship-resistant. It is no longer neutral. It is no longer open. Every participant must be vetted. If someone has control in our legal systems, they immediately have a duty. A responsibility, which means that you can't give anyone control. Because if they have control, all of the other features go away with centralization. A better way to explain the difference between Bitcoin and blockchain is this. The new automobile has come on the scene. Horse breeders, stable managers, and horse carriage builders are freaking out. What do they do? They say, the technology behind the automobile is the pneumatic tire. We would love to adopt this technology. We will introduce pneumatic tires to all our horse carriages. This will preserve our investment in horses. Guess what? Pneumatic tires are great. What is really interesting about the automobile is the no-horses part. It is the actual internal combustion engine. If you say, yes, we like that, but can we put a horse in front, you have missed the point. Blockchain is that. Blockchain is saying, pneumatic tires are the future, but this whole internal combustion engine is a fad... that will either die away on its own, or we will lobby government to ban it. That is where we are with blockchain.
