Abstract

Selon des modes de réalisation, la présente invention concerne un procédé et un appareil de génération de bloc de chaîne d'alliance, un dispositif électronique et un support. Dans les modes de réalisation de la présente invention, si un nœud de chaîne d'alliance ne reçoit aucune donnée de transaction dans une période de génération de bloc actuelle, un bloc vide est généré lorsque la période de génération de bloc actuelle s'achève, et le bloc vide est diffusé dans un réseau de chaîne d'alliance, de telle sorte que le bloc vide soit ajouté sur une chaîne d'alliance à condition que le réseau de chaîne d'alliance vérifie que le bloc vide généré est valide. Après que le bloc vide a été ajouté sur la chaîne d'alliance, le nombre de blocs vides présents en continu derrière le dernier bloc non vide sur la chaîne d'alliance est compté. S'il existe un grand nombre de blocs vides présents en continu derrière le dernier bloc non vide sur la chaîne d'alliance, dans le cas où aucune donnée de transaction n'est reçue dans une période de génération de bloc suivante, la génération d'un nouveau bloc vide est interdite lorsque la période de génération de bloc suivante s'achève. Par conséquent, le gaspillage de puissance de calcul pour générer un grand nombre de blocs vides est réduit, l'espace de stockage est économisé, et le nombre de blocs vides sur la chaîne d'alliance est régulé de manière efficace et sûre.
