Introduction
Definition of Blockchain
Blockchain is a decentralized, distributed ledger technology that records transactions across many computers in such a way that the registered transactions cannot be altered retroactively. This technology ensures transparency, security, and immutability, making it ideal for applications requiring trust and verification.
Overview of Supply Chain Management
Supply chain management (SCM) involves overseeing the flow of goods and services from raw material sourcing to end-user delivery. It encompasses the planning, execution, control, and monitoring of supply chain activities with the aim of creating net value, building a competitive infrastructure, leveraging worldwide logistics, synchronizing supply with demand, and measuring performance globally.
Relevance of Blockchain in Supply Chain
Blockchain’s inherent properties of transparency, security, and decentralization make it particularly suited for supply chain management. It addresses many SCM challenges such as traceability, fraud prevention, and efficient coordination among diverse stakeholders. By providing a single source of truth, blockchain can significantly enhance the reliability and efficiency of supply chains.
Objectives of Using Blockchain in Supply Chain Management
- Enhance Transparency: Provide visibility into every step of the supply chain.
- Improve Traceability: Track the journey of products from origin to destination.
- Increase Efficiency: Automate processes and reduce paperwork.
- Enhance Security: Protect data integrity and reduce fraud.
- Facilitate Compliance: Simplify regulatory reporting and audits.
Technical Specifications Blockchain for Supply Chain Management
Blockchain Architecture
Blockchain architecture consists of a network of nodes, a consensus algorithm, cryptographic hash functions, and a ledger that records all transactions. Each block contains a list of transactions, a timestamp, and a reference to the previous block, forming a chain.
Types of Blockchain
- Public Blockchain: Open to everyone and highly decentralized.
- Private Blockchain: Restricted access, typically used within organizations.
- Consortium Blockchain: Controlled by a group of organizations, offering partial decentralization.
Smart Contracts
Smart contracts are self-executing contracts with the terms of the agreement directly written into code. They automatically execute and enforce the terms of a contract when predefined conditions are met, reducing the need for intermediaries and enhancing trust.
Consensus Mechanisms
- Proof of Work (PoW): Requires participants to solve complex mathematical problems to validate transactions.
- Proof of Stake (PoS): Validators are chosen based on the number of coins they hold and are willing to “stake” as collateral.
- Others: Variants like Delegated Proof of Stake (DPoS), Proof of Authority (PoA), and Byzantine Fault Tolerance (BFT) offer different approaches to achieving consensus.
