Quantum Computing Got 20x Closer. It Threatens A Third of All Bitcoin

Bearish:

• $BTC - Bitcoin faces existential threat from quantum computing potentially by 2029, with $450 billion in vulnerable addresses and no clear consensus on migration path.

  • “So that means on that date, when someone has and it could be Dolev, like, has a a quantum computer of that scale. They could recover a private key from a public key on Bitcoin, Ethereum, or other networks. That would imply, in some sense that they own all of the Bitcoin or could.”

  • “I believe it is quite plausible, although not guaranteed, that we will be able to achieve such a computer by the end of this decade.”

  • “Bitcoin devs need to get their shit together as soon as possible.”

  • “the Bitcoin balance of the top 100,000 vulnerable addresses. And that tallies to 6,700,000, which is about $450,000,000,000 today”

• $ETH - Ethereum faces even more complex quantum vulnerabilities across smart contracts, L2s, and DeFi ecosystem with larger attack surface than Bitcoin.

  • “Con, Ethereum is more complex than Bitcoin. So there's more to fix.”

    Alex·57:32

  • “the attack surface of Ethereum overall is much, much bigger. And because of all the smart contracts, you have, like, a lot more stakeholders that you kinda have to coordinate. So broadly speaking, I think it's a huge challenge.”

    Alex·58:31

  • “There there's just like just the universe of things that could go wrong is so much bigger.”
