Introduction
Advantages of Blockchain in the Supply Chain
1. Transparency: Blockchain ensures transparency all along the supply chain because each transaction is recorded, and the data cannot be manipulated or altered without the network consensus.
2. Traceability: Blockchain enables the tracking of goods and services from their origin to the final delivery. The data recorded on the blockchain can show each step of the journey and help reduce risks, such as theft or damage.
3. Security: Blockchain is inherently secure because the data is distributed across a network of nodes, each holding a copy of the data. To make any changes to the data, consensus must be reached among the majority of nodes, making it virtually impossible to hack.
4. Efficiency: The use of blockchain in the supply chain can streamline and automate workflows, saving time and reducing costs.
Examples of Blockchain in the Supply Chain
1. IBM Food Trust: IBM Food Trust uses blockchain technology to track food products from the farm to the store. This helps to ensure that the food is safe, healthy, and of high quality.
2. Walmart: Walmart uses blockchain technology to track the origin of pork in China. By scanning a code on the packaging, customers can see the history of the product from farm to store.
3. Maersk: Maersk, the largest container shipping company globally, has partnered with IBM to create a blockchain-based platform to track the movement of goods. The platform, called TradeLens, has improved efficiency and transparency in the shipping industry.
