Bitcoin's Quantum Threat: How PACTs Could Save Satoshi's Fortune from Shor's Algorithm

About this episode

The episode discusses the potential impact of quantum computing on Bitcoin and introduces the concept of PACTs as a solution to protect Bitcoin's value.

This is your Quantum Research Now podcast. Imagine this: a single qubit, humming in the cryogenic chill of a dilution fridge at 10 millikelvin, its superposition flickering like a candle in a quantum storm. That's where revolutions begin. Hello, I'm Leo, your Learning Enhanced Operator, diving into Quantum Research Now. Just days ago, on May 1, Paradigm's Dan Robinson dropped a bombshell proposal called PACTs—Provable Address-Control Timestamps. It's making headlines across crypto circles, a preemptive strike against the quantum shadow looming over Bitcoin's $75 billion in dormant wallets, including Satoshi's legendary stash. No quantum company per se, but this ties directly to labs like Google and Quantinuum pushing cryptographically relevant quantum computers closer to reality. Let me break it down with the drama it deserves. Picture Bitcoin's elliptic curve cryptography as a towering castle wall, impregnable to classical battering rams. Shor's algorithm? That's the quantum siege engine, factoring the wall's mortar with eerie efficiency. Classical computers grind exponentially on problems like solving ECDLP for 256-bit keys—think searching every grain of sand on every beach on…
