An electronic device is disclosed. The electronic device comprises: a communication interface; a memory for storing at least one instruction and storing a plurality of pieces of transaction information and a plurality of index values corresponding to the plurality of pieces of transaction information; and a processor for controlling the electronic device by being connected to the memory, wherein the processor executes the at least one instruction to, when a delete request including an index value corresponding to transaction information is received, compare the index value included in the delete request with the plurality of index values stored in the memory, delete transaction information corresponding to the index value included in the delete request from the memory, on the basis of a result of the comparison, generate verification data corresponding to the deletion of the transaction information, and control the communication interface to transmit the generated verification data to an external server included in a blockchain network. L'invention concerne un dispositif électronique. Le dispositif électronique comprend : une interface de communication ; une mémoire pour stocker au moins une instruction et pour stocker une pluralité d'éléments d'informations de transaction et une pluralité de valeurs d'indice correspondant à la pluralité d'éléments d'informations de transaction ; et un processeur pour commander le dispositif électronique en étant connecté à la mémoire, le processeur exécutant la ou les instructions pour comparer, lorsqu'une demande de suppression comprenant une valeur d'indice correspondant à des informations de transaction est reçue, la valeur d'indice incluse dans la demande de suppression avec la pluralité de valeurs d'indice stockées dans la mémoire, pour supprimer des informations de transaction correspondant à la valeur d'indice incluse dans la demande de suppression à partir de la mémoire, sur la base du résultat de la comparaison, pour générer des données de vérification correspondant à la suppression des informations de transaction et pour commander l'interface de communication pour transmettre les données de vérification générées à un serveur externe inclus dans un réseau à chaîne de blocs. 전자 장치가 개시된다. 본 전자 장치는 통신 인터페이스, 적어도 하나의 인스트럭션(instruction)을 저장하고, 복수의 거래 정보 및 복수의 거래 정보에 대응되는 복수의 인덱스 값을 저장하는 메모리 및 메모리와 연결되어 전자 장치를 제어하는 프로세서를 포함하고, 프로세서는 적어도 하나의 인스트럭션을 실행함으로써, 거래 정보에 대응되는 인덱스 값을 포함하는 삭제 요청이 수신되면, 삭제 요청에 포함된 인덱스 값과 메모리에 저장된 복수의 인덱스 값을 비교하고, 비교 결과에 기초하여 삭제 요청에 포함된 인덱스 값에 대응되는 거래 정보를 메모리에서 삭제하고, 거래 정보의 삭제에 대응되는 증명 데이터를 생성하고, 생성된 증명 데이터를 블록 체인 네트워크에 포함된 외부 서버로 전송하도록 통신 인터페이스를 제어한다.
