1. A system to securely conduct a transaction from a first user to a second user when the first user possesses only an alias of the second user, comprising:
one or more memory-coupled processors of a first entity-member of a consortium coupled to memory, wherein the one or more memory-coupled processors execute application code instructions to cause the system to:
store data representing a first alias for a first user and an associated account as a first block in a distributed private blockchain ledger, wherein the first alias does not comprise any personally identifiable data associated with the first user;
communicate instructions to a user computing device of the first user to display a second alias of a second user, wherein the second alias does not comprise any data that can identify any private information of a customer of the second user;
identify an account of the second user corresponding to the alias of the second user stored as a second block in the distributed private blockchain ledger;
initiate, as a third block in the distributed private blockchain ledger, an interaction between the account of the first user and the account of the second user responsive to an interaction request received from the user computing device of the first user; and
track the interaction as the third block in the distributed private blockchain ledger by storing a hash of the second block that maintains an order of the second block and the third block.
