Abstract
(EN)
A dynamic blind voting-based blockchain consensus method for an Internet of Things environment, according to the present invention, comprises: a first step wherein each of devices constituting a blockchain network of an Internet of Things environment selects a voting node by using a transaction list and transmits voting information to a device which is the voting node; a second step wherein the device which has received the voting information generates a block and propagates the block to the devices constituting the blockchain network; and a third step wherein each of the devices which has received the propagated block verifies the block, connects and stores the block to and in a blockchain storage when the block is valid, and ignores the block when the block is not valid.

Selon l'invention, un procédé de consensus de chaîne de blocs basé sur un vote aveugle dynamique pour un environnement Internet des objets comprend : une première étape dans laquelle chacun des dispositifs constituant un réseau de chaîne de blocs d'un environnement Internet des objets sélectionne un nœud de vote au moyen d'une liste de transactions et transmet des informations de vote à un dispositif qui est le nœud de vote; une deuxième étape dans laquelle le dispositif aynt reçu les informations de vote génère un bloc et propage le bloc aux dispositifs constituant le réseau de chaîne de blocs; et une troisième étape dans laquelle chacun des dispositifs ayant reçu le bloc propagé vérifie le bloc, se connecte et stocke le bloc dans un stockage de chaîne de blocs lorsque le bloc est valide, et ignore le bloc lorsque le bloc n'est pas valide.

본 발명에 따르는 사물 인터넷 환경을 위한 동적 블라인드 투표기반의 블록체인 합의방법은, 사물 인터넷 환경의 블록체인 네트워크를 구성하는 디바이스들 각각이 트랜잭션 리스트를 이용하여 투표노드를 선출하고, 상기 투표노드인 디바이스로 투표정보를 전송하는 제1단계; 상기 투표정보를 수신받은 디바이스는 블록을 생성하여 상기 블록체인 네트워크를 구성하는 디바이스들로 전파하는 제2단계; 및 상기 전파되는 블록을 수신받은 디바이스들 각각은 상기 블록을 검증하고, 상기 블록이 유효하면 블록체인 저장소에 블록을 연결하여 저장하고, 상기 블록이 유효하지 않으면 상기 블록을 무시하는 제3단계;를 구비함을 특징으로 한다.
