[Demexp-dev] Request for ideas on delegation

[David MENTRE]

Hello,

I've started to work on the delegation subsystem. I've finally chosen
a relatively simple scheme, following original idea of Jérémy: a
delegation graph per question, without taking into account tags. There
are two functions:
* delegate ~q_id ~delegate_to: to delegate to "delegate_to" on question "q_id";
* vote ~q_id ~vote: to vote on a question "q_id" and cancel any
previous delegation.

Internally, I use the participant identifier to identify to whom one
wants to delegate a question. Now the question is: what should be the
external API for this identifier?

Should all participants publish their participant id? Should we use a
random identifier associated to a participant id and generated only if
a participant wants to be a delegator? In that case, what should be
the lifetime of this identifier?

Another question: should it be possible to delegate to somebody that
has never voted on a question (right now, this is impossible)?

Right now, I don't have any clear ideas. Your input is welcome.

Yours,
d.
