Why Blockchain?

Blockchain prevents fraud and illegal behavior by establishing a record that is encrypted end-to-end and cannot be changed. On the blockchain, privacy concerns may be handled by anonymizing personal data and using permissions to restrict access. Information is kept over a network of computers rather than on a single server, making data access harder for hackers.  

Transactions and data are recorded identically in many places because blockchain employs a distributed ledger. All network members with authorized access view the same information at the same time, ensuring complete openness. Every transaction is immutably documented and time- and date-stamped. This allows members to see the full history of a transaction, essentially eliminating the possibility of fraud.  
Blockchain generates an audit trail that records an asset’s origins at each stage of its transit. This helps offer evidence in sectors where customers are worried about environmental or human rights problems around a product, or in industries plagued by counterfeiting and fraud. It is feasible to communicate data regarding provenance directly with customers using blockchain. Traceability data may also reveal flaws in any supply chain, such as when items are sitting on a loading dock awaiting transportation.  
Speed and efficiency  
Traditional paper-intensive procedures are time-consuming, prone to human error, and often require third-party intervention. Transactions may be performed quicker and more effectively by simplifying these procedures using blockchain. Documentation and transaction information may be kept on the blockchain, removing the need to trade paper. Because there is no need to reconcile numerous ledgers, clearing and settlement may be completed considerably more quickly.  
Smart contracts can increase efficiency and speed up a process. When certain conditions are fulfilled, the next stage in the transaction is automatically initiated. Smart contracts eliminate the need for human involvement as well as dependence on third parties to ensure that contract conditions are fulfilled. In the insurance industry, for example, after a client has submitted the required paperwork to make a claim, the claim may be immediately settled and reimbursed.
