Title
(EN) BLOCKCHAIN CONSENSUS METHOD BASED ON DYNAMIC BLIND VOTING FOR INTERNET OF THINGS (IoT) ENVIRONMENT
(KO) 사물 인터넷 환경을 위한 동적 블라인드 투표기반의 블록체인 합의방법
Abstract
(EN)
According to the present invention, a blockchain consensus method based on dynamic blind voting based for an Internet of things (IoT) environment comprises: a first step of selecting a voting node by each of devices constituting a blockchain network of the IoT environment using a transaction list and transmitting voting information to the voting node, the device; a second step of generating a block by the device receiving the voting information and propagating the block to the devices constituting the blockchain network; and a third step of verifying the block by each of the devices receiving the propagated block, connecting and storing the block to blockchain storage if the block is valid, and ignoring the block if the block is not valid.

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.
