a16z Crypto released an analysis suggesting that concerns about quantum computing threatening cryptocurrencies are often exaggerated. According to PANews, the likelihood of a quantum computer capable of causing real-world disruptions emerging before 2030 is very low. The article highlights that conventional digital signature schemes and zero-knowledge systems like zkSNARKs are not easily susceptible to quantum attacks that follow a 'collect now, decrypt later' model. Prematurely transitioning blockchain systems to quantum-resistant solutions could introduce performance issues, immaturity in engineering, and potential security flaws.
a16z emphasizes even more that, compared to the quantum risks that have not yet materialized, large public blockchains like Bitcoin and Ethereum currently face more immediate challenges. This includes the complexity of protocol updates, governance issues, and vulnerabilities in the implementation layer code. The company advises developers to plan quantum-resistant paths based on a reasonable assessment of timelines, rather than rushing migrations. It also notes that, in the foreseeable future, traditional security issues, such as code defects, side-channel attacks, and fault injections, should take priority over concerns about quantum computing. Resources should be focused on improving audits, fuzz testing, and formal verification.#criptomoeda
