The cryptographic system ensures that all private data (including balance of account, transaction history, etc.) remains secure from potential attackers. The BCN blockchain is fully private so victim selection for targeted attack is a much more complicated process.
To perform requests for transaction history, balances, trading history or personal information, BCN requires a user to sign a request using their private key. Using this approach, only admins and users who were authorised by the account holder, are able to get access to sensitive data.
