Bitcoin Quantum-Proofing: A Dangerous Gamble or Smart Move? Mow Thinks Twice

Ah, the age-old conundrum: speed versus caution. When it comes to Bitcoin’s quantum-proofing, the debate has taken a rather sharp turn, and Samson Mow is here to remind us all that haste makes waste. Or in this case, it could make Bitcoin more vulnerable. How delightful.

Mow Calls Out The Rush

Samson Mow, the self-appointed oracle of Bitcoin, issued a rather pointed warning this past weekend: rush into quantum security, and you might just find yourself with an even worse problem than the one you’re trying to avoid. He might as well have added, “But hey, don’t let that stop you from panicking.”

This, of course, came after the ever-determined Brian Armstrong of Coinbase, alongside his chief security officer, Philip Martin, urged the industry to act now against the looming specter of quantum computing threats. Mow, however, wasn’t exactly thrilled with this call to arms.

“Simply put: make Bitcoin safe against quantum computers just to get pwned by normal computers,” Mow tweeted, the wisdom of a man who clearly prefers to think before leaping into the void.

It’s been almost 10 years since the Blocksize Wars ended and Brian hasn’t changed at all.

He still carries the exact same complete lack of humility and understanding. Brian forms the opinion first, along with a prescribed course of action and timeframe, instead of starting by…

A Ghost From Bitcoin’s Past

At the heart of Mow’s concerns is something that sounds like it should belong to the annals of a bygone era-block size. Yes, block size. The very same issue that split the Bitcoin community wide open during the infamous “Blocksize Wars” of 2015-2017. Back then, it wasn’t just the future of Bitcoin at stake-it was the very soul of the network. And now, it appears we might be headed for round two. Fantastic.

The issue? Larger post-quantum signatures could mean more data per transaction, which translates into fewer transactions per block. Fewer transactions per block means a slower, more congested network. Ah, the joys of progress.

The original Blocksize Wars tore the ecosystem asunder, and Mow warns that the specter of “Blocksize Wars 2.0” might soon rear its ugly head. If we thought the first time was a mess, just wait until this new “battle” starts.

Where Mow Draws The Line

Mow isn’t saying that quantum threats are a figment of our imagination-oh no, far from it. His concern is with timing, not ignoring the problem entirely. Research into potential solutions is already underway, but Mow is steadfast: quantum computers that can crack Bitcoin’s encryption are still a decade or two away. So, rushing into an ill-timed fix for something that’s not even here yet could lead to all sorts of chaos in the present.

The debate is heating up, with new research from Google and Caltech stirring fears about how quickly quantum computing may advance. Armstrong and Martin think the timeline should be sped up. Mow? He argues that the cure might very well be worse than the disease-at least, for now.
