Blockchain and sha256 [16], When they try from Exchange to withdraw, the hash is slightly off. it can’t send money because of that! so it can’t be helped! devil’s proof? ハッシュが僅かにずれるから出せない。これは仕方がない? 悪魔の証明?

Blockchain and sha256 [16], When they try from Exchange to withdraw, the hash is slightly off. it can’t send money because of that! so it can’t be helped! devil’s proof? ハッシュが僅かにずれるから出せない。これは仕方がない? 悪魔の証明?

Let’s return such devil’s proof by indirect proof.
そのような悪魔の証明には、背理法でお返ししましょう。

Suppose d and h were fixed in sha256(Round).
Then, the following hashes with the same or less variation was obtained.
dとhがsha256(Round)内で固定されていると仮定します。
すると、以下のような、同じ、または変動が少ないハッシュ値が得られました。

0xd413cdc676cf5dfa78dde7cc4a9feb54a21ca616360ad2283f07b45eb7c19b32 — (7)

By the way, sha256 has the property that even a slight change can greatly change the result.
ところで、sha256は、僅かな変化であっても、その結果は大きく変わる性質があります。
