COIN BASED: The Quantum Threat to Bitcoin (w/ Drew Armstrong & ArbedOut)


Listen Later

The Coin Based boys (Drew Armstrong & ArbedOut) take the stage in their LIVE AT PUBKEY show at PubKey NYC to discuss the quantum threat to Bitcoin:


  • Why the quantum threat is a real Bitcoin engineering problem
  • The simplest usable mental model of classical bits vs. qubits (and how private keys could be theoretically derived from exposed public keys)
  • Which Bitcoin address/script types are most exposed, why old P2PK outputs are “low-hanging fruit,” and how newer types reduce (but don’t eliminate) exposure
  • The messy debate over what to do about vulnerable old coins... burn them? Throttle them? Or do nothing and accept the risk?
  • The risk of picking the wrong “quantum-safe” scheme too early and why post-quantum migration is difficult in practice
  • Whether this entire quantum debate is perhaps even just a FUD psyop
  • ...and more!
