Benefits of using a blockchain.
- Transparency: Distributed ledger for recording transactions/events in a blockchain do not allow modification of current/preceding records. Hence, data is legit
- Security: Due to consensus, involved internet security protocols to encrypt and share data and immutability - tampering of data is almost impossible.
- Improved traceability: Due to a single source of truth, record-tracing and auditing is much easier and reliable
- Increased efficiency and speed: Again, due to single distributed ledger and global network of miners supporting 247365 - record-keeping, tracking, audit and reconciliation activities are much faster and reliable
- Reduced cost: Instead of maintaining multiple ledgers and too much middlemen ship, single distributed ledgers and pretty low transaction fee(mining fee) involved, costs decrease
