Blockchain 101: A Quick Refresher
Before delving into the convergence of blockchain and supply chains, let’s take a step back to understand this game-changing technology. At its core, a blockchain is a decentralized digital ledger of transactions that is duplicated and distributed across the entire network of computer systems on the blockchain. Every block in the chain contains several transactions, and every time a new transaction occurs on the blockchain, a record of that transaction is added to every participant’s ledger.
Key Features of Blockchain:
- Decentralization: Unlike centralized databases, every network participant sees the entire transaction history, with no single entity in control.
- Transparency: While all transactions are visible, identities remain encrypted, blending openness with privacy.
- Immutability: Once added, transactions can’t be altered or deleted, safeguarding against fraud.
The Advent of Blockchain in Supply Chain
The fusion of blockchain technology with supply chains seemed inevitable. The perennial issues of transparency, authenticity, and traceability in supply chains found a promising solution in blockchain’s core features. Blockchain integration in supply chain operations initially stemmed from the need to enhance transparency. Companies began exploring the tech to track goods, ensure authenticity, and prevent counterfeit products from entering the chain. The decentralized nature of blockchain means that every transaction can be verified, ensuring that each step in the supply chain can be accounted for and validated.
