Satoshi-era bitcoin faces a bigger quantum threat after Google’s new Willow breakthrough

Özet: Kripto piyasasında önemli gelişmeler yaşanıyor.

Google says its Willow quantum chip has cut errors about 40-fold when preparing special states used in quantum calculations, tackling a costly step toward building machines powerful enough to crack bitcoin wallets.

The result, published in Science this week, deals with something that rarely comes up in the bitcoin quantum debate — which usually focuses on how big a machine an attacker would need while underplaying how much of that machine would be occupied getting ready to calculate.

A bitcoin wallet uses a secret key to approve payments and a matching public key that lets the network check those approvals.

Spending typically reveals the public key, while some payment types expose it from the start.

Working backward from it to the secret is supposed to take an impractical amount of computing, which makes it practically impossible to reverse-engineer crypto wallets.

However, a large enough quantum computer running Shor’s algorithm could, in theory, do that math.

Whoever recovered the secret key could sign transactions as the owner, and the network would accept them as genuine.

Mathematician Peter Shor first published the method in 1994, but nobody has yet managed to demonstrate it.

A recovery phrase locked in a physical drawer offers no protection against that, as the attacker would be working from information already sitting on the blockchain.

Some later payment formats hide the public key behind a hash, a digital fingerprint, until the owner spends.
