Understanding the Basics of Blockchain
Introduction to Blockchain
This technology has the potential to transform not only the financial sector but also supply chain management by introducing unprecedented levels of transparency, efficiency, and trust.
How Blockchain Works
Blockchain operates on the principles of decentralization, transparency, and immutability. Each transaction is recorded in a “block” and added to a “chain” of previous transactions.
These blocks are linked using cryptographic hashes, making it nearly impossible to alter or tamper with the data once it has been recorded.
The decentralized nature of blockchain means that no single entity controls the entire network, ensuring that all participants have access to the same, accurate information.
This transparency is crucial in supply chain management, where tracking and verifying the origin and journey of products is essential.
