A próxima grande ameaça às criptomoedas? Computadores quânticos podem decifrar o Bitcoin até 2029

Novos avanços na computação quântica estão pressionando as empresas de cripto a se prepararem para um potencial desafio de segurança que pode remodelar o setor.

O setor de criptomoedas está intensificando os esforços para defender blockchains e carteiras digitais de futuros ataques de computação quântica. Uma nova pesquisa do Google sugere que máquinas quânticas poderosas poderiam quebrar os métodos de criptografia atuais antes do esperado, levantando preocupações em todo o mercado de cripto de US$ 2 trilhões.

Executivos do setor dizem que a ameaça ainda está a anos de distância, mas os preparativos já estão em andamento.

Principais Detalhes

O Google estima que computadores quânticos capazes de quebrar a criptografia atual podem surgir até 2029, antes das previsões anteriores de pelo menos uma década.

A maioria das blockchains, incluindo Bitcoin e Ethereum, depende de criptografia de décadas para proteger as transações. Especialistas alertam que um computador quântico suficientemente avançado poderia derivar chaves privadas de chaves públicas, permitindo que hackers roubem fundos e aprovem transações fraudulentas.

O Bitcoin é visto como especialmente exposto devido ao seu longo histórico de transações e ao grande número de chaves públicas visíveis. Pesquisas sugerem que cerca de 35% do suprimento circulante de Bitcoin pode estar vulnerável, enquanto alguns estudos colocam esse número mais próximo de 50%.

As principais redes de blockchain ainda não implementaram criptografia resistente a recursos quânticos. A Fundação Ethereum tem como meta a proteção total até 2029, enquanto a Fundação Algorand planeja introduzir contas pós-quânticas ainda este ano.

Reação do Mercado

O risco crescente já influenciou o sentimento dos investidores. A Jefferies removeu uma alocação de 10% de Bitcoin de seu portfólio modelo no início deste ano, citando a ameaça de longo prazo representada pela computação quântica.

Por Que Isso Importa

Um ataque quântico bem-sucedido a uma grande criptomoeda poderia desencadear vendas em massa, prejudicar a confiança e causar abalos nos mercados de ativos digitais.

A indústria de cripto ainda tem tempo para se preparar, mas a corrida para atualizar a segurança da blockchain já começou. Os traders estarão atentos para ver se os desenvolvedores conseguem agir rápido o suficiente antes que a computação quântica atinja um ponto de inflexão.
