Title
(EN) COMPUTER IMPLEMENTED SYSTEM AND METHOD FOR STORING DATA ON A BLOCKCHAIN
(FR) SYSTÈME ET PROCÉDÉ MIS EN ŒUVRE PAR ORDINATEUR POUR STOCKER DES DONNÉES SUR UNE CHAÎNE DE BLOCS
Abstract
(EN)
A method of storing data on a blockchain, such as the Bitcoin blockchain, is disclosed. The method comprises generating a plurality of blockchain transactions, wherein a plurality of the blockchain transactions each store therein a respective part (< Content chunk 1>, ) of first data to be stored on the blockchain and second data ( ) indicating that the parts of the first data are related to each other.
(FR)
L'invention concerne un procédé de stockage de données sur une chaîne de blocs, comme une chaîne de blocs Bitcoin. Le procédé comporte la génération d'une pluralité de chaîne de blocs transactions, chaque transaction d'une pluralité des transactions de chaîne de blocs conservant sur celle-ci une partie respective (< Fragment de contenu 1>, <Fragment de contenu 2>) de premières données à stocker sur la chaîne de blocs et de secondes données (<Fanion Metanet >) indiquant que les parties des premières données sont liées entre elles.
