Everyone, don't get lost in those bull run charts just yet. There is a knife sharper than any market fall being sharpened: the threat of Quantum Computing to Blockchain security.

This is not a case of a man worrying about nothing. The recent remarks from the founder of Cardano have exposed the most embarrassing truth in the entire industry—post-Quantum Computing cryptographic protection is not impossible, but the cost is so high that it is suffocating.

**How heart-wrenching is reality?**

To counter the quantum threat, existing cryptographic upgrade solutions would cut the Blockchain speed by nine-tenths and increase data volume by 10 times. In the words of industry insiders: "This is equivalent to forcibly wiping out a zero from your throughput number."

What are the consequences? The network is completely congested, Gas fees are skyrocketing, and ordinary validator node operators are withdrawing due to exploding costs. At that time, the "decentralization" we always speak of will be a mere formality. Can we afford this kind of security trade?

**The Life-and-Death Struggle of Two Paths**

If we have to insist on upgrading the protection, there are only two options in front of the industry:

One is the hash scheme explored by Ethereum - the idea is straightforward, tested over time, but its function is singular, only capable of providing signature protection.

The fake two types are the cryptographic routes promoted by Cardano - much more complex in structure, but with more comprehensive capabilities. Not only can it handle signatures, but it also covers data encryption. Another key point: it can run on ordinary graphics cards, without being restricted to those professional mining machines that might be monopolized by large capital. This could be one of the few choices we have to maintain the true decentralized ethos.

The road is still long, and the choice is imminent.
