Transparency: Blockchain technology is a shared ledger. All participants, who have access, share the same ledger as opposed to individual copies. Change is only brought about through consensus. If consensus is made, then the record of the transaction can be altered with all subsequent records in the network altered in the same way.
Security: All transactions must have a consensus before being encrypted and linked to the previous transaction. As the transactions are recorded on all computers in the network, it would be very difficult to attempt to alter this information on any one ledger, it is all recorded in real-time across all computers on the network.
Improved traceability: As all transactions are recorded in the blockchain, one would find all steps/stops in the ledger.
Increased efficiency and speed: By using blockchain, all members of the network have the same ledger showing all the transactions in real-time, there would be no need to have an intermediary to confirm/trust that the data is accurate between what would possibly be different kinds of ledger formats and data entry which can have possible human errors.
Reduced cost: You would have no need for intermediaries to confirm data accuracy. You would have validation in the blockchain itself with everyone having the same ledger. The cost of implementing different databases would be mute as well all members would be using the same network, the same database.
