Transparency: All contributors and nodes on the blockchain share the same info/transactions on the ledger and everyone can see the same things. The only way things can be changed in the network is if all participants agree and come to a consensus. To change a single transaction would be a collusion of the entire network.
Security: All transactions in the blockchain have to be verified by the participants in the network. Once a transaction is confirmed, all previous transactions are traced including future ones. Info is also stores across multiple networks of computers and makes it difficult for hackers.
Traceability: On the blockchain, every transaction is traced and encrypted, You can see every stop that an asset has made on its journey.
Efficiency and Speed: Since all computers on the blockchain network share the same record-keeping single digital ledger, you dont have to reconcile w multiple ledgers. Also reduces human error through automation.
Reduced costs: Dont need to ely on 3rd parties or middlemen to make guarantees bc you dont have to trust anybody in the system. Not as difficult bc everyone has access to a single immutable record.
