#ETH走势分析 Ethereum is facing an invisible technological race. The shadow of Quantum Computing looms over the entire encryption world, and the time window may be more urgent than everyone expects.

Ethereum co-founder Vitalik recently issued a rare warning: the possibility that Quantum Computing poses a substantial threat to the network before 2030 has reached 20%. Even more dangerously, this timeline could be moved up to 2028 — a year that seems far away, but in fact is only three years away.

The core of the problem lies in the ECDSA signing mechanism. This system supports the security of all external accounts, but it is as fragile as paper in the face of Quantum Computing. Once the public key is exposed on the chain, future quantum devices could theoretically perform a reverse crack, directly emptying wallets. There is no need to break the entire chain; it is enough to tear open this line of defense.

Vitalik's emergency plan sounds like a sci-fi script: a hard fork to roll back to a safe block, mass freezing of traditional wallets, and mandatory migration to quantum-resistant accounts backed by zero-knowledge proofs. But this is just a fallback solution; the real way out is to lay the groundwork in advance - developing smart contract wallets, deploying post-quantum signature algorithms certified by the National Institute of Standards and Technology, and establishing a cryptographic infrastructure that can be quickly switched.

There is a divergence in the industry regarding the timeline of threats. Conservatives believe there is a buffer period of 10 to 20 years, while radical predictions lock the emergence of high-performance Quantum Computing in the late 2030s. However, Vitalik's logic is clear: migrating a global blockchain network requires several years of preparation, and delays are the biggest risk variable.

This is not about creating panic, but rather a wake-up call for the entire ecosystem. The future of $ETH does not lie in reacting after the emergence of Quantum Computing, but in building a defense system now. The starting gun for the technological race has already fired, and the preparation time left for the encryption world may be shorter than everyone imagines.
