The $740B Prize

Forty-two months ago I wrote The $65B Prize citing Divesh Aggarwal et al's 2019 paper Quantum attacks on Bitcoin, and how to protect against them. They noted that:

the elliptic curve signature scheme used by Bitcoin is much more at risk, and could be completely broken by a quantum computer as early as 2027, by the most optimistic estimates.

It is time to re-visit the "optimistic estimates", so follow me below the fold.

The $65B Prize

Senator Everett Dirksen is famously alleged to have remarked "a billion here, a billion there, pretty soon you're talking real money". There are a set of Bitcoin wallets containing about a million Bitcoins that are believed to have been mined by Satoshi Nakamoto at the very start of the blockchain in 2008. They haven't moved since and, if you believe the bogus Bitcoin "price", are currently "worth" $65B. Even if you're skeptical of the "price", that is "real money". Below the fold, I explain how to grab these million Bitcoin and more for yourself.
