Neste capítulo, exploraremos o fascinante mundo da criptografia de conhecimento zero e veremos como ela se aplica perfeitamente ao roteiro da Ethereum, possibilitando realmente escalar e acomodar a demanda de adoção em massa por espaço de blocos. A tecnologia de conhecimento zero é um tópico muito complexo e depende de muitas regras matemáticas que não conseguiremos explicar em detalhes. O objetivo deste capítulo é garantir que você possa entender por que a criptografia de conhecimento zero oferece uma oportunidade única para a Ethereum e se encaixa bem no roteiro de escalonamento.
