database_api.get_potential_signatures

Purpose

Cette méthode retourne l'ensemble de toutes les clés publiques (public key) pouvant potentiellement signer une transaction (transaction) donnée. Cet appel peut être utilisé par les portefeuilles (wallet) pour filtrer leur ensemble de clés publiques afin de ne garder que le sous-ensemble pertinent, avant d'appeler get_required_signatures pour obtenir le sous-ensemble minimal.
