This article explores the diverse applications of blockchain in supply chain management and healthcare, illustrating how it addresses longstanding challenges in these sectors.

Understanding Blockchain Technology

What is Blockchain?

At its core, blockchain is a distributed ledger technology (DLT) that records transactions across multiple computers. This decentralized structure ensures that no single entity has control over the entire network, fostering trust among participants. Each block in the chain contains a list of transactions, and once added, the data cannot be altered without consensus from the network.

Key Features of Blockchain

1. Decentralization:

Unlike traditional databases managed by central authorities, blockchain operates on a peer-to-peer network. This decentralization increases transparency and reduces the risk of data manipulation.

2. Transparency:

All transactions are recorded on a public ledger, accessible to all participants. This visibility fosters accountability and trust among stakeholders.

3. Security:

Blockchain employs cryptographic techniques to secure data, making it resistant to unauthorized access and fraud.

4. Immutability:

Once information is added to the blockchain, it cannot be changed or deleted without consensus, ensuring data integrity and reliability.

Applications of Blockchain in Supply Chain Management

The supply chain encompasses multiple stages, from raw material sourcing to product delivery. Blockchain can enhance efficiency, traceability, and accountability within this complex ecosystem.

1. Enhanced Traceability
