Abstract
a invenção diz respeito a tecnologias de blockchain tais como o blockchain de bitcoin, e a tokenização de ativos ou entidades. isso é particularmente adequado para implementar uma folha de pagamento em uma plataforma de blockchain e compreende um método (100) e sistema (1) de transferência de criptomoeda a partir de um primeiro nó (3) para um segundo nó (7). ambos os nós (3, 7) são associados com uma folha de pagamento e têm um par de criptografia assimétrica respectivo, cada par incluindo uma chave mestre privada e uma chave mestre pública. chaves privadas e públicas respectivamente adicionais podem ser determinadas com base na chave mestre privada, na chave mestre pública e em um valor gerador em cada nó. as chaves privadas e públicas adicionais podem formar uma estrutura hierárquica. um segredo comum pode ser determinado em cada um dos nós (3, 7) com base nas chaves privadas e públicas adicionais. o segredo comum pode ser usado para transmitir informação confidencial com segurança através de uma rede de comunicações (5).
