  Transparency, private keys, and decentralization are the major concerns of blockchain privacy. Moreover, blockchain security necessarily satisfies the privacy requirements of users in large corporations.
  Use cases that necessitate privacy-ensured blockchain are as follows.
   •  Transactions of financial
