Google has just sounded the highest alarm in the cryptocurrency world.

They have found a specific way to crack Bitcoin's underlying algorithm.
How long does it take to crack a private key?
9 minutes.

Bitcoin's average block time is 10 minutes.
Quantum computers can brute-force crack it in just 9 minutes.
This time difference is extremely deadly.
You just finished sending, and your transaction is still queued in the mempool.
Hackers can intercept it directly, derive your private key,
and then preemptively transfer your coins into their own wallet.

Previously, the industry generally believed that quantum cracking would take several months.
Google's latest model has cut the required computing power by 90%.
Now, only 1,200 logical qubits are needed to complete the calculation.
The top 1,000 richest Ethereum wallets could be completely looted in 9 days.

Additionally, 67 million dormant Bitcoins are fully exposed.
This includes the early block rewards mined by Satoshi Nakamoto in the Genesis Block.
Public keys have been on the chain for years, now all turned into live targets.

Google has made an extremely rare decision this time.
They refused to publish the specific attack code in the paper.
Instead, they only verified the results with zero-knowledge proofs to the academic community.
This is the first time in the history of quantum computing research.
They treated the entire blockchain as a high-risk vulnerability that cannot be disclosed externally.

The cryptographic defenses of modern digital assets have been torn apart.
All existing defense mechanisms are now rendered ineffective.
