#Gate广场四月发帖挑战 Is the "quantum doomsday" in the crypto world accelerating? Google warns of an escape timeline: 2029!

Researchers warned on Tuesday that future quantum computers might be able to crack some of the encryption protecting Bitcoin and other digital assets with fewer resources than previously thought, making discussions about how the industry should prepare even more urgent.
The researchers did not specify that such machines currently exist, but they indicated that recent studies suggest the computational power needed for such attacks could be lower than many early estimates.
In a recent blog post published by Google Research, the researchers stated that future quantum computers could break elliptic curve cryptography — a widely adopted public key encryption technology in the market today.
Their latest estimates show that the quantum hardware scale required to crack the so-called ECDLP-256(, a mathematical problem used to secure cryptocurrency wallets and transactions, could be reduced by about 20 times.
This does not mean that Bitcoin or Ethereum will suddenly face security risks. However, in a white paper released on Monday, Google researchers pointed out that the most clear defense is to switch to post-quantum cryptography)PQC( — a new security mechanism designed to resist powerful machine attacks. They also urged the crypto industry to reduce avoidable risks during this period.
“We urge all crypto communities with security vulnerabilities to immediately migrate to PQC,” they said.
“Escape” timeline: 2029!

Current quantum computers (such as IBM or Google models) are still in the stage of hundreds of physical qubits. 2029 is a “radical warning,” aimed at pushing the industry to accelerate technological iteration rather than an absolute “doomsday.”
Beware of “quantum panic” scams
As the 2029 deadline approaches, many scam projects claiming to offer “quantum-resistant wallets” or “quantum-secure tokens” will appear in the market.
Identification: Genuine security upgrades will come from Bitcoin Core developers or the Ethereum Foundation, not from some suddenly emerged new tokens.

Summary and Recommendations
“Don’t panic, but evolve.” 2029 is more like a technological watershed. For ordinary people, the most important thing now is not to learn quantum physics but to stay attentive to industry technical proposals (such as Bitcoin’s PQC improvement proposals) and develop good on-chain habits (like not reusing addresses). The crypto industry is essentially an eternal arms race between “encryption” and “cracking,” and history has shown that defenders usually have enough time to resolve crises through hardware and software upgrades. )
