To PQ or Not to PQ: Bitcoin's Quantum Dilemma Gets Messier

The Bitcoin community is currently engaged in what can only be described as a high-stakes game of quantum chicken, debating whether racing to implement post-quantum cryptography by 2029 is brilliant preparation or an elaborate way to shoot yourself in the foot before the enemy even shows up.

Enter Samson Mow, the eternal contrarian and founder of JAN3, who seems to have made a career out of telling the crypto world to slow down. He's pushing back aggressively against Coinbase CEO Brian Armstrong's call for faster post-quantum upgrades, basically telling everyone to hold their horses and let future problems stay future problems. "Solving the QC problem later rather than sooner is the best course of action," Mow insisted, proving once again that he's the guy at the party saying "well, actually" to everything.

Mow's concerns read like a anxiety spiral in bullet point form. First up: implementing untested PQ solutions could accidentally open doors for today's boring classical computers to waltz right through. Second: these cryptographic heavyweights would bloat transaction sizes so dramatically—PQ signatures run a juicy 10-125x larger than current ones—that throughput would crater harder than a DeFi protocol's token price. This delightful scenario has already been dubbed Blocksize Wars 2.0, because apparently the Bitcoin community learned nothing from the last decade of fighting. Third, and most tinfoil-hat-friendly: Mow whispered the forbidden words about NSA backdoors lurking in current PQ solutions being pushed as official standards. The plot thickens.

For those wondering what actual deployment looks like in the real world, Solana has been kind enough to run the numbers and discovered that implementing current PQ solutions would slow everything down by a whopping 90%. Yes, you read that correctly—ninety percent. At that point, your blockchain isn't quantum-resistant, it's just resistant to anyone actually using it.

The timing of this whole circus is particularly spicy. Google's Quantum AI team recently dropped a report that reads like a horror movie synopsis: breaking Bitcoin's encryption might require far fewer qubits than anyone anticipated—around 500,000 physical qubits or 1,200-1,450 stable logical qubits, down from the millions everyone was casually throwing around before. Google is now urging everyone to upgrade to PQ by 2029 to protect what could be nearly 7 million BTC sitting in vulnerable wallets. That's a lot of sats waiting nervously for the quantum boogeyman.

But here's where we remember Bitcoin's history: the network moves slower than a Bitcoin fee confirmation during a bull market. Protocol changes take years, generate endless tribal warfare, and occasionally spawn entire competing coins. Expecting a smooth, timely migration to post-quantum standards might be the most optimistic take since someone bought Bitcoin at $69,000 because "this time it's different."

Charles Edwards of Capriole Investment, never one to mince words or catch a falling knife, put it bluntly: BTC won't see a new all-time high until it migrates to PQ. That's either profound wisdom or the world's most expensive motivation technique.
