chapter390, [SORA] Let’s put a new mechanism that can freely load/store data on the blockchain.

Currently, we are using the blockchain for drive maintenance features in software called FromHDDtoSSD.So we found a way ...

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?
