La nueva prueba de confianza de las criptomonedas: qué cadenas están verdaderamente preparadas para la tecnología cuántica y cuáles solo están hablando
Burns Brief
El problema cuántico de las criptomonedas ya no es un experimento mental lejano. Los participantes del mercado están sopesando cuidadosamente las implicaciones, y el resultado probablemente dependerá de condiciones macroeconómicas y de volumen más amplios. Esté atento a la reacción de $BTC $ETH: un movimiento decisivo por encima o por debajo de niveles clave confirmará la próxima tendencia.
Crypto’s quantum problem is no longer a distant thought experiment. With NIST finalizing standards, Coinbase warning of exposed addresses, and Google shrinking the resources needed to break today’s signatures, projects are being forced to show whether “quantum-ready” is a concrete plan or just a slogan. NIST finalized its first three post-quantum cryptography standards in August 2024 and told organizations to begin migrating immediately, with a 2035 deadline to deprecate quantum-vulnerable public-key algorithms from its guidelines. Coinbase's advisory board reached the same conclusion in a recent report, arguing that blockchains, wallet providers, exchanges, and custodians should prepare before urgency arrives, and that unresolved public decisions around migration are already deterring some investment. In March, Google set an internal PQC migration timeline for 2029 and updated its threat model to prioritize authentication services.

That convergence turns post-quantum planning from a debate in cryptography into a test of governance and credibility. Crypto wallet threat illustration Why this matters If your assets sit on a chain, in a wallet, or with a custodian that has no credible post-quantum plan, you are effectively trusting that today’s signatures stay unbroken for decades. As standards harden and vendors like Trezor and AWS productize quantum readiness, institutions and sophisticated users are already using these plans (or the lack of them) to decide where to keep capital.
