They are lower-powered "siblings" of the ownership key, which has the sole power to transfer the assigned Urbit identity. Using Bridge, you can change the Ethereum addresses used for your proxies.

                                                                                                                      There are three types of proxy.

The voting proxy is unique to galaxies, since only power galaxies have seats in the Senate.
