(** Only delegates with at least one roll take part in the amendment
procedure. It works as follows:
- Proposal period: delegates can submit protocol amendment
proposals using the proposal operation. At the end of a proposal
period, the proposal with most supporters is selected and we move
to an exploration period. If there are no proposals, or a tie
between proposals, a new proposal period starts.
- Exploration period: delegates can cast votes to test or not the
winning proposal using the ballot operation. At the end of an
exploration period if participation reaches the quorum and the
proposal has a supermajority in favor, we proceed to a cooldown
period. Otherwise we go back to a proposal period. In any case, if
there is enough participation the quorum is updated.
- Cooldown period: Nothing happens, this period is only a time gap
between exploration and promotion periods. At the end of a cooldown
period we move to a promotion period.
- Promotion period: delegates can cast votes to promote or not the
proposal using the ballot operation. At the end of a promotion
period if participation reaches the quorum and the proposal has a
supermajority in favor, we move to an adoption period. Otherwise we
go back to a proposal period. In any case, if there is enough
participation the quorum is updated.
- Adoption period: At the end of an adoption period, the proposal
is activated as the new protocol. *)
