The eternal dilemma of our age-the safety of cryptocurrencies from the ominous shadow of quantum computers. And yet, amid this swirling storm of digital uncertainty, a single voice rises above the rest-John Woods, the esteemed CTO of Nillion, offers the simplest of solutions for Bitcoinâs quantum “resistance.” Spoiler: itâs not what you think.
John Woods’ Surprisingly Simple Solution to Quantum-Proof Bitcoin
Woods, with the confidence of a man who has already solved all of humanityâs problems (except maybe world peace), tells us the only thing standing between Bitcoin and quantum doom: donât spend it. Yes, you heard that right-just donât spend your precious BTC. Thatâs the key to keeping it safe from the death grip of quantum computers. Simple, no? In his view, any Bitcoin that is transferred to a new account and left untouched is entirely safe from quantum mischief-at least for now.
Before you scoff, letâs provide some context. You see, the debate around quantum threats is hardly unanimous. Charles Edwards, the big brain at Capriole Investments, suggests that quantum computers need just about 700 usable qubits to crack Bitcoinâs cryptographic defenses. And we all know how “only 700” sounds like a reasonable number when we’re talking about the future of currency and technology, right?
Bitcoin is quantum resistant right now if you send your funds to a new account and donât spend from it.
Without spending, your public key is never revealed and thus there is no target for the quantum computer to attack.

According to Edwards, unless someone gets their act together quickly, quantum computers could crack Bitcoin wide open in the next couple of years. Yet, the exact timing of this apocalypse remains a mystery-because, of course, the future is always uncertain.
To counteract this potential disaster, Woods advises users to create a new account and deposit Bitcoin they have no intention of spending. Sounds like an easy enough solution, doesnât it? The logic is straightforward: as long as you donât spend, your public key remains as hidden as a squirrel on a winter’s day. No public key, no quantum computer attack. Seems foolproof, right?
But here’s where the plot thickens: once you start spending, things get dicey. A powerful quantum machine could, in theory, take that public key, work some mathematical wizardry, and derive your private key. And at that point, we all know what happens next-someone out there is going to make off with your hard-earned digital gold.
Woods is, naturally, quick to remind us of this peril: “Without spending, your public key is never revealed and thus there is no target for the quantum computer to attack.” Makes you want to put that Bitcoin into a nice, cozy, undisclosed account, doesnât it?
For now, Woods insists this is just a temporary band-aid, a holding action until someone invents a way to shield Bitcoin users from quantum computer tyranny. Stay tuned. Or, you know, just donât spend your BTC for the time being-whatever feels more secure.
Quantum Computers: The Real Culprit Behind Bitcoinâs Recent Price Drop?
Speaking of crises, another prominent figure, Michael Saylor from Strategy, has weighed in on the quantum debate. Unlike Woods, Saylor is less concerned about the immediate threat of quantum computers. He believes that even if quantum computers can crack Bitcoinâs cryptography, they wonât be able to fundamentally destroy the asset itself, which rests on the solid bedrock of mathematics. So, maybe there’s hope after all?
Interestingly enough, this talk of quantum doom seems to be affecting Bitcoinâs market performance. As of this very moment, Bitcoin is trading at $82,653.09, a drop of 9.92% in the last 24 hours. But donât fret! Investors are still buying, with trading volume spiking by a healthy 45.34% to $115.2 billion. So, perhaps the quantum apocalypse is not so terrifying after all-unless, of course, youâre holding onto BTC for dear life.
