Abstract

Sont prévus dans les modes de réalisation de la présente description un procédé de traitement de transactions de chaîne de blocs, un nœud de chaîne de blocs et un dispositif électronique. Le procédé consiste à : collecter un premier lot de transactions qui sont impliquées dans un nième cycle de proposition de consensus d'une chaîne de blocs ; exécuter une opération de consensus sur le premier lot de transactions, et s'il existe un deuxième lot de transactions, exécuter, en parallèle, une opération de collecte sur le deuxième lot de transactions selon une séquence de lot, le deuxième lot de transactions étant un lot de transactions qui n'ont pas été collectées dans le nième cycle de proposition de consensus ; effectuer une opération d'exécution de transaction sur le premier lot de transactions, et s'il existe un troisième lot de transactions, exécuter, en parallèle, une opération de consensus sur le troisième lot de transactions selon la séquence de lot, le troisième lot de transactions étant un lot de transactions qui ont été collectées dans le nième cycle de proposition de consensus et n'ont pas été soumises à un consensus ; envoyer dans la chaîne de blocs un résultat d'exécution de transaction du premier lot de transactions de façon à effectuer une confirmation de transaction sur le premier lot de transactions ; et après que les confirmations de transaction de tous les lots de transactions dans le nième cycle de proposition de consensus sont obtenues, exécuter une opération d'écriture de bloc sur tous les lots de transactions dans le nième cycle de proposition de consensus.
