Ao contr\u00e1rio dos sistemas atuais que necessitam de recursos computacionais importantes, <strong>o GKR permite verificar c\u00e1lculos complexos com uma efici\u00eancia nitidamente superior.<\/strong> Esta tecnologia poderia reduzir drasticamente o tempo de processamento e os custos associados \u00e0s transa\u00e7\u00f5es que utilizam provas zero-knowledge.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" class=\"wp-block-heading\" id=\"o-gkr-muda-o-jogo-para-as-provas-zero-knowledge\">O GKR muda o jogo para as provas zero-knowledge<\/h2>\n\n\n\n<p>As provas <strong>zero-knowledge<\/strong> constituem hoje o fundamento t\u00e9cnico das solu\u00e7\u00f5es de escalabilidade mais promissoras do <a href=\"https:\/\/preprod.investx.fr\/pt\/investir-criptomoedas\/comprar\/ethereum\/\">Ethereum<\/a>. O protocolo GKR traz uma otimiza\u00e7\u00e3o maior a este n\u00edvel ao permitir verificar computa\u00e7\u00f5es aritm\u00e9ticas muito <strong>mais rapidamente<\/strong> do que os m\u00e9todos tradicionais como os <strong>SNARKs ou os STARKs.<\/strong><\/p>\n\n\n\n<p>A particularidade do GKR reside na <strong>sua abordagem interativa de verifica\u00e7\u00e3o<\/strong>, que decomp\u00f5e os c\u00e1lculos complexos em etapas verific\u00e1veis de forma sequencial. Este m\u00e9todo reduz consideravelmente a carga computacional necess\u00e1ria para validar uma prova. Para os programadores de rollups e solu\u00e7\u00f5es layer 2, isto significa prazos de finaliza\u00e7\u00e3o mais curtos e uma largura de banda acrescida.<\/p>\n\n\n\n<p>O impacto no throughput das transa\u00e7\u00f5es poderia ser substancial. Os projetos que utilizam <strong>ZK-rollups<\/strong> como o <strong>zkSync, StarkNet ou Polygon zkEVM<\/strong> acompanham de perto estes desenvolvimentos. Uma melhoria de <strong>30 a 50% na velocidade de verifica\u00e7\u00e3o das provas<\/strong> traduzi-se-ia diretamente num aumento equivalente do n\u00famero de transa\u00e7\u00f5es processadas por segundo.

Desde a transi\u00e7\u00e3o para o Proof of Stake com <strong>The Merge<\/strong>, o roteiro concentra-se na <strong>escalabilidade atrav\u00e9s dos rollups e do sharding.<\/strong> O GKR integra-se perfeitamente nesta estrat\u00e9gia ao otimizar a camada de verifica\u00e7\u00e3o, que representa atualmente um estrangulamento t\u00e9cnico.<\/p>\n\n\n\n<figure class=\"wp-block-embed is-type-rich is-provider-twitter wp-block-embed-twitter\"><div class=\"wp-block-embed__wrapper\">\n<blockquote class=\"twitter-tweet\" data-width=\"500\" data-dnt=\"true\"><p lang=\"en\" dir=\"ltr\">What is GKR?<br><br>GKR is a fast way to prove you did a calculationwithout making someone check all your work again.
