#加密市场回调 **Vitalik Buterin warns causes industry shock: Countdown to quantum computing threat?**

Ethereum founder Vitalik Buterin recently issued a warning at the Devconnect developer conference that has left the entire crypto community on edge — quantum computers may be capable of breaking the current blockchain encryption systems before 2028.

**How real is the threat?**

Currently, the Elliptic Curve Digital Signature Algorithm (ECDSA) relied upon by mainstream cryptocurrencies like $BTC and $ETH is nearly unbreakable in traditional computing environments. However, quantum computers can use Shor's algorithm to factor large primes at an exponential speed, theoretically allowing for the private key to be reverse-engineered. In simpler terms: right now, your wallet is a safe, but with the arrival of quantum computers, it could become a cardboard box.

**Is a four-year window period enough?**

Vitalik emphasized that Ethereum needs to complete the migration to quantum-resistant encryption algorithms by 2028. This timeline sounds reasonable, but for a decentralized network that processes millions of transactions daily and involves hundreds of billions of dollars in assets, the complexity of the technical upgrade is no less than changing the engines of an airplane in flight.

**Market Reaction Polarization**

Some people have already begun researching anti-Quantum Computing concept projects, and some veteran players say they are not surprised. After all, the crypto world has been continuously facing various "doomsday prophecies" since its inception - from regulatory crackdowns to technological crises, the surviving projects have actually become stronger.

Quantum threats are not black swans that will erupt tomorrow, but they are indeed the sword of Damocles hanging over our heads. Paying attention to technological advancements and diversifying risk allocation may be more meaningful than anxiety.

How do you assess this risk? Will you adjust your position structure because of this?
