This is precisely the role of Satoshi is SHA-256.

Having launched a project of this nature, I state clearly that we will see it through - reliably and completely.
The reason is simple, "this project did not arise by chance".

I myself once misjudged the relationship between hash bit length and the size of the search space.
They are not the same. They are entirely different concepts, and confusing them leads directly to flawed security assumptions.

Until quantum computation entered the picture, this misunderstanding did not immediately surface as a critical issue.
It was tolerated, perhaps unconsciously - because classical limits masked the problem.
But quantum computation has now arrived.

With it, the urgent necessity emerged to address bit length and search space as separate dimensions of security.
This project was launched precisely because that distinction became clear.
And having reached that point, I can assure you, multiple viable paths forward already exist.

If we begin by listing conditions one after another, it quickly becomes unclear which assumptions truly matter.
Blockchains have become that complex.
So what should be done?

In such cases, the correct approach is to define the objective first.
Once the objective is clear, the solution often becomes surprisingly simple.

Conditions fluctuate with circumstances. What holds today may fail tomorrow.
Repeating that cycle does not lead to quantum resistance.
Therefore, we must first fix the objective.

So, what is the objective when countering Grover’s algorithm?

Quite simply:
to design a structure in which quantum search cannot effectively enter the hash function itself.

That is the core idea.

By doing so, we preserve the continued use of hash functions as a structural foundation.
This allows the critical components of existing blockchain systems, already built around hashing to remain largely intact, without massive redesign or prolonged validation.
From a time perspective, this is a decisive advantage.

By contrast, entirely different paradigms - such as those represented by multivariate polynomial systems - raise a separate question, can they truly operate correctly and reliably within a blockchain environment?
Answering that requires long and careful validation, which places them at a disadvantage when time matters.

Next, when implementing this objective, additional mechanisms must be considered - such as methods that avoid hard forks.
These have also been addressed.
Not merely in theory, but through practical testing on live blockchain systems.

In summary, the priority is clear:

1. A hash function capable of incorporating quantum - resistant mechanisms.

2. A secure method to introduce it without requiring a hard fork.

If these two conditions are met, they are sufficient above all others to carry us through the quantum challenge.
