David Carvalho, CEO of Naoris Protocol and former hacker, believes the crypto industry is dangerously unprepared for the rise of quantum computing.
He warns that most blockchain networks — including Bitcoin and Ethereum — rely on cryptography that could be rendered obsolete by future quantum breakthroughs.
While the industry dismisses the threat as distant, Carvalho argues that attackers are already harvesting encrypted data today in hopes of decrypting it later with quantum tools — a tactic known as “harvest now, decrypt later.”
The real danger, he says, will come from the intersection of AI and quantum computing, enabling precision attacks that won’t trigger alarms but quietly compromise wallets, validators, and governance systems.
“It won’t be loud,” Carvalho warns. “It’ll be silent and irreversible.”
Despite efforts like post-quantum key formats and upgrades such as BIP-360, adoption remains slow. Carvalho points out that real-world infrastructure — cloud nodes, APIs, centralized systems — remains vulnerable, regardless of how decentralized the blockchain protocols claim to be.
Projects like Naoris are working on defense systems modeled after national security protocols, but time may be running out.
