USECASE: Decentralised Sexual Health Cred.

1. Participants allow access to their health-record for the purpose of STD
checking, to specifically nominated actors.
2. Actors share information about their health-checks and sexual adventures
with other actors.
3. When an Actor has sex with another actor, they're able to log it in an
app, and identify particulars that relate to health.

Party A: has sex with 6 new actors each week, but usually practices safe
sex.

Party B: has had sex with 1 actor since last health check (PARTY A) but has
met a new actor they'd like to have sex with and are unsure whether they're
'safe'.

Party C: is the new person Party B met and wants to have sex, but has not
got a record because they're concerned about privacy.

Party D: is married, has had sex with Party C whom they are not married to
and does not want to disclose this paid event unless they have concerns
over the health of their partner and children.
