+Proxied NIP-05 Authetication
+-----------------------------------
+
+`draft` `optional` `author:benthecarman`
+
+This NIP defines a way for clients to ask a relay to fetch the JSON document for a given NIP-05 address on their behalf.
+
+## Motivation
+
+A bad actor could be logging IP addresses and doing all of kinds of analytics on users that are making requests to a NIP-05 address in order
+to verify the user. This could be proxied through a trusted relay to help protect the user.
+
+The `NIP-05` parameter is used so the `PROXY` message can be later extended for other proxied requests in the future (ie image downloading).
+
+## Definitions
+
+This NIP defines a new message, `PROXY`, which clients can send to ask a relay to proxy a request through
+
+```
+["PROXY", "NIP-05", <NIP-05 address>]
+```
+
+And, when sent by relays, of the following form:
+
+```
+["PROXY", "NIP-05", <NIP-05 address>, <JSON returned from NIP-05 address>]
+```
+
+## Expected Behavior
+
+If clients are worried about a relay lying to them, they can send the same `PROXY` request to multiple relays, if any of them give a different result,
+they can assume that relay may be malicious.
+
+Relays would be expected to fetch the JSON on behalf of the user, in order to prevent potential DoS attacks the relays could cache these requests to
+save on bandwidth.
