Oh, the drama! A new a16z crypto research paper says, “Hold your horses, folks! 🚀 Quantum computers aren’t about to turn Bitcoin into a pumpkin at midnight!” 🌙 According to them, the real headache for blockchains is the long, messy migration process, not some sudden “Q-Day” apocalypse. But hey, investors on X are like, “Uh, no, the quantum boogeyman is closer than you think, buddy!” 👻
Bitcoin’s Quantum Angst: a16z Says Chill, Others Say Pill! 💊
In the hilariously titled article, “Quantum computing and blockchains: Matching urgency to actual threats,” a16z’s Justin Thaler (yeah, the Georgetown brain 🧠) says, “Everyone’s freaking out like it’s Y2K all over again! 🗓️ But timelines for a quantum computer that can crack Bitcoin are more overstated than Mel Brooks’s accent!” He argues this hype is like a bad sitcom plot, distracting teams from real issues like, you know, implementation bugs. 🐞
Thaler defines a “cryptographically relevant quantum computer” (CRQC) as a machine that can run Shor’s algorithm faster than a barista makes your latte. ☕ But don’t worry, he says a CRQC in the 2020s is “highly unlikely”-unless it’s in a sci-fi movie. 🎬 Public milestones? More like quantum marketing fluff. 🥱
He’s like, “Trapped-ion, superconducting, neutral-atom platforms? None of them are close to cracking Bitcoin’s nuts. 🥜 They need millions of qubits and error rates lower than my patience for bad puns.” 😏
But here’s the kicker: Thaler says encryption and signatures are like apples and oranges. 🍎🍊 Harvest-now-decrypt-later (HNDL) attacks? Yeah, they’re a thing for encryption, but signatures? Not so much. Bitcoin’s ledger is already public, so the real threat is someone forging signatures to steal your coins, not decrypting your grandma’s secret cookie recipe. 🍪
Bitcoin’s Special Headaches: Because Why Not? 😩
Thaler still gives Bitcoin a side-eye, saying it’s got “special headaches” like slow governance, limited throughput, and abandoned coins just sitting there like forgotten leftovers. 🍕 But he’s like, “Chill, you’ve got at least a decade before quantum computers start knocking on your door.” 🚪
“Bitcoin changes slower than a sloth on a Sunday,” he writes. “And if the community can’t agree on something, it’s hard fork city, baby!” 🍴 Plus, migrating to post-quantum signatures? Owners gotta do it themselves. No autopilot here! 🚗
And let’s not forget Bitcoin’s low transaction throughput. “Migrating all those vulnerable funds? That’ll take months at this rate. Might as well grab some popcorn!” 🍿
Thaler’s also skeptical about rushing into post-quantum signature schemes. Hash-based signatures? Huge! Lattice-based schemes? Complex and buggy! He’s like, “Blockchains, don’t jump on the bandwagon just because the media’s screaming. You’ll weaken your security faster than a banana goes brown.” 🍌
Industry Split: Quantum Chicken or Quantum Egg? 🥚
Nic Carter and Alex Pruden are like, “Hold up, a16z! You’re underestimating the quantum threat harder than I underestimate my ability to finish this pizza.” 🍕 Pruden’s like, “Respect, but no. The threat is closer, the progress faster, and the fix harder than a Monday morning.” ☕
He points to neutral-atom systems with 6,000+ qubits, saying, “We’re not in Kansas anymore, Dorothy!” 🌪️ And error correction? “Surface code error correction went from research to engineering last year. It’s happening, people!” 🚀
Pruden highlights Google’s estimates, saying a quantum computer could break RSA-2048 with just a million qubits running for a week. “That’s a twenty-fold reduction! The trajectory’s steeper than my caffeine intake.” ☕
He reframes blockchains as quantum magnets, saying, “Public keys tied to visible value? That’s like leaving a $150B vault open with a ‘Please rob me’ sign.” 🚨 And migrating? “Blockchains are slower than a snail in molasses. A bank can upgrade its stack, but blockchains need global consensus and millions of users to move their keys. Good luck!” 🐌
Pruden agrees panic is bad but says, “Waiting too long is worse. The industry’s gonna wait, then a QC milestone will trigger a panic. Mark my words!” 🔮
At press time, Bitcoin was chilling at $91,616. 🤑
