• Security: providing privacy based on the notion of anonymous transactions without any obligations to cooperate with third parties. This will enhance the demand of a cryptocurrency.
  • Confidentiality: the issue of confidentiality can be solved by going back to the essence of cryptocurrencies. These currencies are based on the cryptographic information. The anonymity of the users is provided by pseudonyms and encryption of the ledger. However, public keys can be used to give a general idea of the transactions made by a user. A solution is to find a way to assign the public keys in a different way to make transactions untraceable. This will dictate true confidentiality of transactions conducted on a blockchain network.
