 ## Design Overview
 
 ### Concepts
 
-All authors are initially not admitted to write to the relay.  There are two ways to gain access write to the relay. The first is by attempting to post the the relay, upon receiving an event from an author that is not admitted, the relay will send a direct message including the terms of service of the relay and a lighting invoice for the admission cost.  Once this invoice is payed the author can write to the relay. For this method to work the author must be reading from the relay. An author can also pay and accept the terms of service via a webpage `https://<relay-url>/join`.

 If "pay to relay" is enabled, all incoming events are evaluated to determine whether the author is on the relay's whitelist or if they have paid the admission fee and accepted the terms. If "pay per note" is enabled, there is an additional check to ensure that the author has enough balance, which is then reduced by the cost per note. If the author is on the whitelist, this balance check is not necessary.

 *Threat*: An attacker gains write access by paying the admission fee, and then floods the relay with a large number of spam events.
 
 *Mitigation*: The attacker's admission can be revoked and their admission fee will not be refunded. Enabling "cost per event" and increasing the admission cost can also discourage this type of behavior.
