Congratulations, you've nearly completed our module on the seven implicit design principles of Blockchain. Principles that enable a Blockchain economy and society. By design principles, we were referring to the foundations of a system of values. In our view, these values ought to inform our blueprint for the next era of the digital economy. The design of new services and business models and the redesign of markets, the enterprise, and governments. For each of these seven principles, we described a current problem to be solved in society. For principle one, on network integrity, we talked about the erosion of trust in institutions. Consensus mechanisms could help restore trust in systems even if we couldn't trust all the actors in those systems. We looked at such consensus mechanisms as proof of stake and proof of activity to name a few. For principle two, on distributed power, we talked about the centralization of power. Even in Western democracies and free economies. Blockchain as a peer-to-peer network could help us restore equality. For principle three, was value as an incentive. We looked at the need for alignment of economic values and how Blockchain align the incentives of everyone using it. Other principles addressed the security, privacy, and preservation of property rights. Finally, for the principle of inclusion, we looked at how Blockchain could help us plug the unbanked into the financial system. The global economy works best when it works for everybody. So, on behalf of my co-author, Alex Tapscott and our academic partner INSEAD, thanks for joining us. If you have questions, please post them on the discussion forum. As always, we'd love to hear from you.
