Classical synchronous consensus algorithms are leaderless: processes exchange their proposals, retain the maximum value and decide when they see the same choice across a couple of rounds. Indulgent consensus algorithms are more robust in that they only require eventual synchrony, but are however typically leader-based. Intuitively, this is a weakness for a slow leader can delay any decision.
