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 a testing_vote period. If there are no proposals, or a tie between proposals, a new proposal period starts.
• Testing_vote period: delegates can cast votes to test or not the winning proposal using the ballot operation. At the end of a testing_vote period if participation reaches the quorum and the proposal has a supermajority in favor, we proceed to a testing period. Otherwise we go back to a proposal period. In any case, if there is enough participation the quorum is updated.
• Testing period: a test chain is forked for the length of the period. At the end of a testing period we move to a promotion_vote period.
• Promotion_vote period: delegates can cast votes to promote or not the tested proposal using the ballot operation. At the end of a promotion_vote period if participation reaches the quorum and the tested 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.
