The Danger to Bitcoin Isn’t Visible — Until It’s Too Late
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.
Alex is Editor-in-Chief of Coindoo and co-founder of Millennial Media Group, with nearly a decade of experience covering financial markets - crypto first, then everything else. It started in 2016 with Bitcoin. Like most people at the time, he didn't fully understand it - so he kept digging. Blockchain, tokenomics, the projects, the cycles. That curiosity never stopped, and eventually pulled him into traditional markets too: equities, commodities, macro. Not because he left crypto behind, but because you can't properly understand one without the other. What drives him is straightforward: he wants to know why something is happening, not just that it's happening. Most market coverage stops at the headline - price up, price down, here's a chart. Alex finds that kind of reporting actively unhelpful. If you walk away from an article without understanding the mechanism behind the move, what did you actually learn? He holds a degree in Tourism from New Bulgarian University - not the most obvious path into financial markets, but markets have a way of pulling in people who are simply too curious to stay out. He has authored over 200 in-depth analyses and more than 10,000 articles across crypto and traditional finance. He still thinks every day in markets teaches him something new. That's probably why he hasn't stopped.
