3.1 Supply Chain Management

Blockchain can enhance traceability in supply chains. Each transaction is recorded on a public ledger, allowing all parties to verify the authenticity of products.

            // Example of a simple smart contract for supply chain tracking
            pragma solidity ^0.8.0;

            contract SupplyChain {
                struct Product {
                    uint id;
                    string name;
                    string status;
                }

                mapping(uint => Product) public products;

                function addProduct(uint _id, string memory _name) public {
                    products[_id] = Product(_id, _name, "Created");
                }

                function updateStatus(uint _id, string memory _status) public {
                    products[_id].status = _status;
                }
            }
            

3.2 Healthcare

In healthcare, blockchain can securely store patient records, giving patients control over their data and improving the interoperability of health information systems.

3.3 Financial Services

Blockchain enables faster and cheaper cross-border payments, reduces fraud, and ensures transparency in transactions.
