Abstract
(EN) This application discloses a method and an apparatus for processing an account in a blockchain, a storage medium, and a computer device. The method includes: receiving a freezing instruction sent by a user, the freezing instruction being used for instructing to freeze a target account; generating a freezing lock according to the received freezing instruction, the freezing lock including a freezing lock public key; generating a freezing request according to the freezing instruction and the freezing lock public key, the freezing request being used for requesting to freeze the target account by using the freezing lock public key; and transmitting the freezing request to a device in a blockchain, so that the device in the blockchain records a freezing event according to the freezing request, the freezing event being used for instructing the device in the blockchain to reject to perform resource transfer on the target account. In this application, a technical problem of account insecurity caused by leakage of an account private key can be resolved.
(FR) La présente invention se réfère à un procédé et un appareil de traitement de compte dans une chaîne de blocs, à un support de stockage et à un dispositif informatique. Le procédé consiste à : recevoir une instruction de gel envoyée par un utilisateur, l'instruction de gel servant à commander le gel d'un compte cible ; générer un blocage par gel selon l'instruction de gel reçue, le blocage par gel comprenant une clé publique de blocage par gel ; générer une demande de gel selon l'instruction de gel et la clé publique de blocage par gel, la demande de gel étant utilisée pour demander de geler le compte cible à l'aide de la clé publique de blocage par gel ; et envoyer la demande de gel à un dispositif dans une chaîne de blocs afin que ce dernier enregistre un événement de gel selon la demande de gel, l'événement de gel servant à commander au dispositif dans la chaîne de blocs de refuser de mettre en oeuvre un transfert de ressources sur le compte cible. La présente invention permet de résoudre le problème technique posé par l'insécurité d'un compte due à la fuite d'une clé privée du compte.
