Quantum's Knocking: Bitcoin’s ‘We Should Probably Do Something (But Maybe Later?)’ Moment by 2029

The Bitcoin community is currently locked in a particularly dramatic game of quantum chicken—do we treat 2029 as a hard deadline to quantum-proof the network, or is this more of a “we’ll get to it after we finish arguing about ordinals” situation? The debate is heating up, and so are the degen takes.

Samson Mow, founder of JAN3 (a firm whispering sweet nothings into nation-states’ ears about BTC adoption), has stepped in as the chief buzzkill. His message: hold your horses on slapping untested post-quantum (PQ) crypto onto Bitcoin like it’s a DIY firmware update. “Solving the QC problem later rather than sooner is the best course of action,” Mow declared, sounding like the one guy who refuses to preheat the oven during a potluck. Unsurprisingly, this doesn’t sit well with Coinbase’s Brian Armstrong, who’s out here trying to herd cats toward a PQ upgrade yesterday.

Mow isn’t just being difficult for fun—though kudos if he is. He’s genuinely concerned that rushing PQ crypto could backfire spectacularly. For starters, untested PQ schemes might open Bitcoin to attacks from current classical computers—because nothing says “upgrade” like swapping one vulnerability for a bigger one. Also, PQ signatures are huge, like 10–125x bulkier than today’s svelte ECDSA. That means fewer transactions per block and throughput slower than a dial-up meme download. Cue the whispers: “Blocksize Wars 2.0: Electric Boogaloo.”

Solana, bless its high-speed soul, actually ran the numbers and found current PQ implementations could throttle the chain by 90%. That’s right—go from zero to hero in milliseconds, then back to dial-up speeds with one standards update. Truly the crypto version of “jumping out of the frying pan and into a quantum oven.”

Mow also casually tossed in a spicy garnish: what if the U.S. NSA is secretly promoting PQ standards with backdoors? Because in crypto, no conspiracy theory is too wild if it involves nation-states and cryptographic sabotage. Maybe it’s paranoid. Or maybe it’s just Tuesday in Web3.

The debate went supernova after Google Quantum AI dropped a report suggesting Bitcoin’s encryption might crack sooner than expected. Their math says you’d need roughly 500,000 physical qubits or 1,200–1,450 stable logical ones to break ECDSA—way below the old “millions of qubits” estimates. Google’s advice? Upgrade to PQ by 2029 or risk ~7 million BTC going full Schrödinger’s wallet (simultaneously secure and pwned).

But let’s be real: Bitcoin moves slower than a bear market Lambo delivery. Protocol upgrades are glacial, contentious, and require more consensus than getting degen apes to agree on a single meme coin. Charles Edwards of Capriole Investment even claims BTC won’t hit a new all-time high unless it migrates to PQ—so apparently, the next bull run is hinging on cryptographers finally settling their differences.

Meanwhile, crypto OGs like Adam Back remain unfazed, shrugging at quantum hype like it’s just another “sky is falling” narrative. Grayscale’s Zach Pandl echoed the vibe: “Investors should not fret. In our view, there is no security threat to public blockchains from quantum computers today.” But then he added, “It’s time to accelerate efforts to prepare for our post-quantum future,” which is like saying “don’t panic” while quietly building a bunker
