Abstract
(EN)
Provided are a blockchain-based data compression method and apparatus, and an electronic device. The method comprises: a service party compressing, according to a preset compression template, target data to be stored (110); assembling the compressed target data and a unique identifier of the compression template into a certificate storage transaction (120); and sending the certificate storage transaction to a node device of a blockchain, so that the node device queries, in response to the certificate storage transaction, a smart contract, published in the blockchain, corresponding to the unique identifier, and calls a compression template declared in the smart contract to verify a data format of the target data, and if the verification is passed, storing a certificate of the target data (130).

La présente invention concerne un procédé et un appareil de compression de données basés sur une chaîne de blocs, et un dispositif électronique. Le procédé comprend les étapes consistant à : compresser, par une partie service, selon un modèle de compression prédéfini, des données cibles à stocker (110) ; assembler les données cibles compressées et un identifiant unique du modèle de compression dans une transaction de stockage de certificat (120) ; et envoyer la transaction de stockage de certificat à un dispositif nœud d'une chaîne de blocs, de telle sorte que le dispositif nœud demande, en réponse à la transaction de stockage de certificat, un contrat intelligent, publié dans la chaîne de blocs, correspondant à l'identifiant unique, et appelle un modèle de compression déclaré dans le contrat intelligent pour vérifier un format de données des données cibles, et si la vérification est positive, stocker un certificat des données cibles (130).
