Quantum Computing: The Boogeyman of Bitcoin or Just a Really Bad Joke?

by

Ah, the delightful world of quantum computing! It’s like the mythical creature that everyone talks about but no one has ever seen—sort of like a unicorn, but with more math and fewer rainbows. Recently, the air has been thick with speculation about whether cryptocurrencies, particularly our dear friend XRP, are at risk of being turned into digital confetti by these quantum beasts. The burning question on everyone’s mind: if Bitcoin isn’t quantum-proof, why on Earth would the U.S. government consider it a strategic reserve asset? Perhaps they enjoy a good gamble? 🎲

Enter David Schwartz, Ripple’s CTO and the man with a plan—or at least a very interesting opinion. His take? Bitcoin is about as quantum-proof as a paper umbrella in a monsoon, but the panic surrounding it is often more exaggerated than a bard’s tale of heroism. He likened quantum computing to cold fusion—always just a few years away, like that one friend who promises to visit but never quite makes it. For over a decade, experts have been saying practical quantum computing is eight years away. And yet, here we are, still twiddling our thumbs and waiting for the magic to happen.

“Bitcoin isn’t quantum-proof. But quantum computing is like cold fusion. Cold fusion was 30 years away 30 years ago and still seems about 30 years away today. Quantum computing has been 8 years away for more than 10 years now.

If they live long enough, we will need to make…”

Now, Schwartz does concede that at some point, cryptocurrencies like Bitcoin, Ethereum, and the XRP Ledger (XRPL) will need to don their quantum-resistant armor. But that day is not today, my friends. The current quantum-safe cryptographic methods are about as useful as a chocolate teapot when it comes to blockchain applications—inefficient, difficult to implement, and frankly, not worth the hassle right now.

Strategy? Wait and See

Schwartz advises us to sit tight and wait for truly effective quantum-resistant algorithms to emerge. If someone were to attempt to make a single account or UTXO quantum-safe today, it would be akin to trying to teach a cat to fetch—possible, but oh-so-tedious. It would involve locking it to the hash of a public key without revealing the key itself. Not exactly practical for the average Joe or Jane, is it?

So, does this mean quantum computers are just a bunch of hot air? Not exactly. Schwartz acknowledges that quantum computing is as real as the existential dread that comes with checking your bank balance. But breaking encryption? Weakening cryptographic security? That’s not happening anytime soon. The commonly used standards—SHA-256, SHA-512, RIPEMD-160, SECp256k1, Ed25519—are safe, at least for now. So, breathe easy, folks! 😌

Tomorrow’s Problem?

The conversation has been reignited recently thanks to new quantum innovations, like Google’s Willow. This chip reportedly solved in mere minutes what would take the most powerful supercomputer an eternity to accomplish. Naturally, this got the rumor mill churning: if a quantum computer can do that, what’s stopping it from cracking crypto wallets like a nutcracker at a holiday party?

For now, the answer seems to be: a whole lot of nothing. The technology just isn’t there yet. But the industry will need to stay ahead of the curve, watching, waiting, and when the time is right, adapting—like a chameleon at a disco party. 🦎💃
