Title
(EN) SYSTEMS AND METHODS FOR STORING OBJECT STATE ON HASH CHAINS
(FR) SYSTÈMES ET PROCÉDÉS DE STOCKAGE D'ÉTAT D'OBJET SUR DES CHAÎNES DE HACHAGE
Abstract
(EN)
A method for storing object state on hash chains. A read request that includes a received field name is received by an object with a plurality of fields. A field value that corresponds to the received field name is retrieved from a hash chain of the object by traversing the hash chain. A block is found that includes the field value from the plurality of field values that corresponds to the received field name. A response to the read request that includes the field value is generated and transmitted·
(FR)
L'invention concerne un procédé de stockage d'état d'objet sur des chaînes de hachage. Une demande de lecture comprenant un nom de champ reçu est reçue par un objet avec une pluralité de champs. Une valeur de champ correspondant au nom de champ reçu est extraite d'une chaîne de hachage de l'objet en traversant la chaîne de hachage. Un bloc comprenant la valeur de champ est détecté parmi la pluralité de valeurs de champ qui correspondent au nom de champ reçu. Une réponse à la demande de lecture comprenant la valeur de champ est générée et transmise.
