• Title: Double Proxy Interface

Double Proxy is the easiest way for side/external Contracts to locate and query the DFO. As the main Core Contract of a DFO is the Proxy, it also can be updated by Proposals. So, directly link the Proxy to external Contracts can be really a problem. To avoid this, it is better to link external contracts with the DoubleProxy. DoubleProxy is the Proxy of the Proxy, and is a Delegate that keeps track of the most recent Proxy address and all the other previous Proxies. Because it has a very lightweight and simple structure and logic, it does not need of changes, so it can be used as a secure anchor.
