Poll Types

Poll Types can be configured in the settings object of the poll, the setting dictates how multiple response tags are handled in the kind:30068 event.

PollType: singlechoice: The first response tag is to be considered the actual response.
PollType: multiplechoice: The first response tag pointing to each id is considered the actual response, without considering the order of the response tags.
PollType: rankedchoice: The first response tag pointing to each id is the considered the actual response, while also taking into account the order of the response tags.

Counting Results

Results can be queried by fetching kind:30068 events from the relays specified in the poll. The results displayed should only be 1 vote event per pubkey. In case of multiple events for a pubkey, the event with the largest timestamp should be considered.

Curation

The clients may configure fetching results by specific people. This can be achieved by creating kind:30000 follow sets, and fetching results only from the follow set. Clients can also employ other curation algorithms, like Proof Of Work and Web of Trust scores for result curations.
