Abstract
(EN) A random sampling BFT consensus method and system, and a computer program are disclosed. The random sampling BFT consensus method can comprise the steps of: electing some from among all of validators through random sampling using a verifiable random function (VRF) and multinomial distribution; and performing blockchain consensus through voting by the elected validators.
(FR) Un procédé et un système de consensus BFT d'échantillonnage aléatoire et un programme informatique sont divulgués. Le procédé de consensus BFT d'échantillonnage aléatoire peut comprendre les étapes consistant : à choisir certains validateurs parmi tous les validateurs en effectuant un échantillonnage aléatoire à l'aide d'une fonction aléatoire vérifiable (VRF) et la distribution multinomiale ; et la réalisation d'un consensus de chaîne de blocs par l'intermédiaire du vote des validateurs sélectionnés.
(KO) 랜덤 샘플링 BFT 합의 방법과 시스템 및 컴퓨터 프로그램이 개시된다. 랜덤 샘플링 BFT 합의 방법은, VRF(Verifiable Random Function)와 다항분포(multinomial distribution)를 이용한 랜덤 샘플링 방식을 통해 전체 검증자(validator) 중 일부를 선출하는 단계; 및 상기 선출된 검증자의 투표를 통해 블록체인 합의를 수행하는 단계를 포함할 수 있다.
