Des nœuds du réseau P2P sont déployés sous la forme de nœuds de chaîne publique ou de nœuds de diverses chaîne d'accès spécial, respectivement ; les nœuds sont déployés sous la forme d'au moins une couche logique dans une couche de blocs de données, d'une couche de commutation de réseau, d'une couche d'infrastructure de plateforme, d'une couche d'application décentralisée et d'une couche inter-domaine selon les rôles ou les fonctions des nœuds d'un réseau de chaîne de blocs ; les couches réalisent des opérations de données dans leurs propres couches indépendamment les unes des autres et la production, la vérification et la mémorisation de données de blocs pendant la transaction peuvent être effectués au moyen d'une interaction de données parmi les couches. De plus, en déployant la couche inter-domaines, en gérant des transactions inter-chaînes, en effectuant une vérification de transaction et en fournissant un contrat intelligent inter-chaînes, le problème d'absence de prise en charge des transactions inter-chaînes par un système classique de chaîne de blocs est résolu.
