mkr-authority

Custom authority for allowing MKR to govern MKR.

Intentionally simple. Once set as the MKR token's authority, if the MKR token's owner field is subsequently set to zero, the following properties obtain:

• any user may call MKR's burn function
• only authorized users (according to the MkrAuthority's wards) can call MKR's mint() function
• only the root user set in the authority can call other auth-protected functions of the MKR contract
• only the root user can modify the MkrAuthority's wards or change the root

Though this contract could be used in different ways, it was designed in the context of an overall design for control of the MKR token via MKR governance as illustrated below.

<~~~ : points to source's authority
<=== : points to source's root or owner

-------    -------    ------------    --------------    -----
|Chief|<~~~|Pause|<===|PauseProxy|<===|MkrAuthority|<~~~|MKR|===>0
-------    -------    ------------    --------------    -----

Such a structure allows governance proposals voted in on the Chief to make arbtirary changes to the MKR token and its permissions subject to a delay. (See DappHub contracts DSChief and DSPause for implementations of the voting contract and the delay contract, respectively.)

Note that the MkrAuthority allows for upgrading of the MKR token's authority or owner by the root.
