## Contracts

### DAO

We introduce a DAO contract which estabishs the public interface of the DAO core, and provides a context within which the core contracts may securely call each other.

Each of the core contracts must first be deployed. Then the DAO contract is deployed, and for each core contract, makes the first and only call to `registerDAO` to set the address of the DAO contract. All calls are then mediated by the DAO contract's public interface. This enables us to enforce the security of the core contracts.
