This gives enough time for a user to notice a migration request published by an attacker and gives the user enough time to publish a competing migration request pointing to an earlier `kind:1776` whitelisting event.

Clients should keep track of when a `kind:1777` event should take into effect, counting at least 30 days from the time of seeing the event and not trusting the event timestamp. This is to prevent an attacker creating an evil `kind:1776`, its attestation, and a `kind:1777` event with its attestation and not publishing them until the 30 days of the attestation have elapsed.

Additionally, clients SHOULD broadcast the `kind:1777` events to the relays it normally writes to. This is to prevent an attacker from creating a short-lived NIP-65 relay list where only a subset of users will see an evil `kind:1777` event but not widespread enough for the real owner to notice it.

### Future Work
Key migration can be done in multiple ways. This is an initial implementation that can work. This mechanism should be extended with other, alternative mechanisms, that can leverage different flows/tradeoffs (e.g. social recovery).
