The Diamond module contains various functions that require ownership of Beanstalk to execute in Beanstalk. This includes Pausing and Unpausing Beanstalk and upgrading Beanstalk via Diamond Cuts.

See [EIP-2535 Diamond](/developers/overview/eip-2535-diamond.md) to read more about Beanstalk's upgradable proxy implementation.

The Diamond consists of 4 facets:

* [Ownership Facet](/developers/protocol/diamond/ownership-facet.md)
