Blockchain in Supply Chain Management in Africa

Introduction

Blockchain technology, originally developed as the underlying architecture for cryptocurrencies like Bitcoin, has evolved into a transformative tool for various industries. One of the most promising applications of blockchain is in supply chain management. In Africa, where supply chains are often complex and fragmented, blockchain has the potential to enhance transparency, efficiency, and trust. This article explores the role of blockchain in supply chain management in Africa, highlighting its benefits, challenges, and potential applications across different sectors.

The Concept of Blockchain

Definition and Principles

Blockchain is a decentralized, distributed ledger technology that records transactions across multiple computers in such a way that the registered transactions cannot be altered retroactively. This ensures transparency and security. Each block in the blockchain contains a list of transactions, and these blocks are linked together in a chronological chain (Nakamoto, 2008).

Key Features

Decentralization: Unlike traditional databases, blockchain does not rely on a central authority. Instead, it operates on a peer-to-peer network, which enhances security and reduces the risk of central points of failure.
Immutability: Once a transaction is recorded on the blockchain, it cannot be altered or deleted. This immutability ensures the integrity of the data.
Transparency: All participants in the blockchain network have access to the same data, which enhances transparency and trust.
Security: Blockchain uses cryptographic techniques to secure transactions, making it highly resistant to fraud and cyberattacks (Swan, 2015).
