# Architecture Course - Problem 4 # #4 Identity-Management We find ourselves in the same small town of the last exercise. The peer-to-peer payment system is a success! Everyone is really happy with it. Now, other towns and regions want to clone our system, which would give rise to a multiplicity of DHTs and membranes. We want to be able to manage identities in such a way that merchants from one town can go to another town. For this exercise, we want to focus specifically in the identity-management side of things. Here are the challenges we want to focus on: - How do we manage identities, profile and personal information, in a context of multiple membranes and DNAs? - We want to foster local regional economy. How can we build a system that can enable trust in that a person that we don't know is a local from the region? (Verifiable claims) - How do we fix private-key management issues? What do we do when keys are lost, or stolen? ## Important infrastructure Holochain will provide a set of "infrastructure DNAs" to help you build happs with identity-management in mind. **[Read this article](https://hackmd.io/Y4QSGqn6T_amCvHv6T9f6A)** to find out about them, and try to think how you would use them in your solution.
