There are only 3 possibilities, and I have explained what happens in 2 out of them. I summarize again. ECDSA is compromised, which would make Fun88 Việt broken.SHA256 is compromised, which may make Fun88 Việt broken depending on the type of compromise.Both are compromised, which I didn't address because if ECDSA is broken Fun88 Việt is already broken anyway. As for this, claiming that quantum computers will start cracking these algos is like saying that curing cancer will soon unlock faster than light travel. Both are complex scientific problems but they operate entirely in different domains with unrelated mechanisms. The same is true for ECDSA and SHA256, even though both are algorithms they could not be more different from each other. If one is ends up being broken that doesn't guarantee that the other one will be broken soon or ever, and vice versa. You even call them related, but they are not. They are only related in the sense that they are used together in practice in this case. The solution right now for the user is just to wait. Do not believe any FUD but also don't believe anyone who is selling quantum secure solutions just yet. I believe it would be worthwhile to add a small explanation of collisions and preimages. For the rest of the explanation into the details I leave it to the post of stwenhao which is great. Collision attack: This occurs when you can find at least two inputs that produce the same hash. Hash (a) == Hash (b). More random.Preimage attack: You have the ability to take a hash and derive the input that produced it. Targeted attack and more dangerous.
