Introduction
In today's globalized world, supply chain management is a critical aspect of any manufacturing company's operations. Ensuring the security, transparency, and traceability of the supply chain has become increasingly important as companies strive to meet customer demands for product authenticity and safety. One technology that has gained significant attention in this context is blockchain. Blockchain technology, which underlies cryptocurrencies like Bitcoin, offers unique features that can greatly enhance supply chain security. This paper aims to provide an overview of blockchain technology, explain its fundamental concepts and workings, and discuss the key features that make it suitable for enhancing supply chain security. Blockchain Technology Overview Blockchain technology is a decentralized, distributed ledger system that records transactions across a network of computers in a secure and immutable manner. It was initially developed as the underlying technology for Bitcoin, but its applications have since expanded to various industries beyond cryptocurrencies. Fundamental Concepts of Block chain Decentralization: Unlike traditional centralized systems where a single entity (such as a bank or government) controls the ledger, block chain operates in a decentralized manner. This means that no single entity has complete control over the network, making it resistant to censorship and tampering. Distributed Ledger: A blockchain consists of a chain of blocks, with each block containing a set of transactions. These blocks are stored across a network of nodes (computers) that participate in the network. Every node maintains a copy of the entire blockchain ledger, ensuring redundancy and data integrity. Cryptographic Security: Blockchain uses advanced cryptographic techniques to secure transactions and prevent unauthorized access. Each transaction is cryptographically linked to the previous one, forming a chain that is challenging to alter without consensus from the network. How Blockchain Works Transaction Creation: When a participant initiates a transaction on the blockchain, it is broadcast to the network. This transaction typically includes details such as the sender, receiver, and the amount of value being transferred. Verification and Consensus: Nodes on the network validate the transaction by verifying its authenticity and ensuring that the sender has the required funds. This verification process is carried out through a consensus mechanism, such as Proof of Work (PoW) or Proof of Stake (PoS), depending on the blockchain's design. Adding to the Blockchain: Once a transaction is verified and approved by the network, it is added to a new block. This block is then linked to the previous block, forming a chain of blocks. Once added, the information in the block becomes immutable, meaning it cannot be altered without consensus from the majority of the network. Key Features of Blockchain for Supply Chain Security Blockchain technology offers several key features that make it particularly suitable for
enhancing supply chain security:
