Abstract
(DE)
Die Erfindung betrifft ein Verfahren zum Erzeugen einer verketteten Blockchain-Struktur in einem elektronischen Speicher, welches eine die Blockchain initiierende Wurzel (100) und mindestens einen mittels eines ersten Datenelements (101.1, 102.1) unmittelbar mit der Wurzel (100) der Blockchain verketteten ersten Block (101, 102) umfasst. Dieses soll ein einfaches und aufwandsarmes Löschen von Datensätzen bzw. Blöcken aus der Blockchain ermöglichen. Dies wird erfindungsgemäß dadurch erreicht, dass in jeden ersten Block (101, 102) ein zusätzliches zweites Datenelement (101.2, 102.2) integriert wird, welches einen jeden ersten Block eindeutig identifizierenden Deskriptor enthält.
(EN)
The invention relates to a method for generating a linked blockchain structure in an electronic memory which comprises a root (100) initiating the blockchain and at least one first block (101, 102) linked directly to the root (100) of the blockchain by means of a first data element (101.1, 102.1). This is intended to enable simple and economical deletion of data records or blocks from the blockchain. This is achieved according to the invention in that an additional second data element (101.2, 102.2) is integrated in each first block (101, 102) and contains a descriptor uniquely identifying each first block.
(FR)
Procédé de production d'une structure de chaîne de blocs enchaînée dans une mémoire électronique, comprenant une racine (100) initiant la chaîne de blocs et au moins un premier bloc (101, 102) enchaîné directement avec la racine (100) de la chaîne de blocs au moyen d'un premier élément de données (101.1, 102.1). Ce procédé doit permettre d'effacer de manière simple et avec peu de moyens des ensembles de données ou des blocs dans la chaîne de blocs. A cet effet, un deuxième élément de données supplémentaire (101.1, 102.1) est intégré dans chaque premier bloc (101, 102), lequel élément contient un descripteur identifiant chaque premier bloc de façon univoque.
