Les applications distribuées utilisent des protocoles de consensus afin de maintenir un état consistent sur plusieurs machines dans un réseau. L'avènement récent de bitcoin et des algorithmes basés sur la blockchain a suscité un regain d'intérêt pour ces protocoles, notamment en ce qui concerne leur capacité à passer à l'échelle et à tolérer les participants malicieux. Cependant, cette attention a été source de confusion, submergeant un sujet déjà vaste et complexe avec des assertions imprécises et une terminologie variable. Dans cette thèse, nous proposons une unification des fondamentaux de la blockchain, grâce à un formalisme capturant un large éventail de modèles communs pour les protocoles de consensus. Nous utilisons ce formalisme pou...
