Zusammenfassung:A method and device employing a blockchain to process the validity of a digital asset The method comprises: when a digital asset is issued, acquiring the validity of the asset, an issue date timestamp and an expiration date timestamp (201); determining transaction information having validity attributes according to the validity of the asset, the issue date timestamp and the expiration date timestamp (202); and storing the transaction information having the validity attributes in a blockchain (203). In the invention, the validity of a digital asset, an issue date timestamp and an expiration date timestamp are included in transaction information, and validity management of the digital asset is recorded in a blockchain, such that a complete life cycle of the digital asset can be found in the blockchain to ensure credibility. L'invention concerne un procédé et un dispositif qui utilisent une chaîne de blocs pour traiter la validité d'un actif numérique. Le procédé consiste : à acquérir, lorsqu'un actif numérique
