The application of blockchain technology in supply chain management has expanded in the last five years, providing better transparency and traceability of data. Using a decentralised ledger, blockchain ensures that all transactions and product movements are accurately recorded and verified, providing better security and efficiency.
Blockchain records transactions across multiple computers to ensure security, transparency, and immutability. Each transaction is grouped into a “block,” which is linked in a “chain” using cryptography. This structure makes it nearly impossible for any party to alter previous transactions without altering all subsequent blocks, providing a secure and tamper-resistant system. Blockchain, therefore, is a way to securely store and share supply chain data verified by a network of participants rather than a centralised authority.
Traditional supply chains often lack visibility across the entire network of suppliers, manufacturers, and distributors. Blockchain can verify the origin and authenticity of goods by recording every transaction. Each participant has access to the same data, allowing for better tracking of products from their source to their destination. Because blockchain ledgers are permanent and unchanging, any issues within the chain can be easily traced back to a single point.
Centralised databases used in traditional supply chains can be vulnerable to cyberattacks, fraud, and manipulation. Blockchain’s decentralised nature makes it harder for offenders to alter or tamper with the data. Once a block of data is recorded and verified, it cannot be changed without consensus from the network, which enhances security and prevents unauthorised access. Transparency enhances trust by creating a shared, immutable ledger for all participants.
Supply chains often rely on paper-based documentation, manual checks, and intermediaries, leading to inefficiencies, delays, and high costs. Blockchain can automate and streamline many processes in the supply chain, such as payment verification, contract execution (via smart contracts), and goods authentication, eliminating human intervention. This leads to quicker transactions and reduced costs.
The different parties (suppliers, manufacturers, logistics providers) often operate in silos, leading to miscommunication and coordination issues. Blockchain enables all stakeholders to work on the same distributed ledger, ensuring all parties can access consistent and up-to-date information. This enhances collaboration and ensures data accuracy across the supply chain.
Many consumers and businesses demand greater transparency regarding their products’ ethical and environmental impact. Verification of sources can be difficult. Supply chain struggles with fraud, including lies about the origin of goods, manipulation of financial and inventory records, and counterfeit products. Blockchain technology can track and verify the origin of raw materials and finished goods, allowing consumers and businesses to confirm that products meet specific ethical or sustainability standards (e.g., fair trade, organic, free of child labour, carbon-neutral).
Large organisations in the fast-moving consumer goods sector (FMCG: food-and-beverage, pharmaceutical) are using blockchain to trace the origins of their raw materials. Walmart and IBM use blockchain to track each supply chain step in real-time, enabling faster identification of problems like recalls. Maersk and IBM’s TradeLens platform uses blockchain to provide secure documentation of shipping processes, reducing paperwork fraud in global logistics. Provenance, a blockchain-based platform, allows brands to share verified data about their products with consumers and suppliers, fostering better collaboration and trust throughout the supply chain. The Responsible Sourcing Blockchain Network (RSBN) is used to track the ethical sourcing of minerals like cobalt, ensuring they are not mined using child labour or unsustainable practices. The fashion industry and rare earth minerals supply chains are examples of sectors adopting blockchain for sustainability.
Blockchain is combined with artificial intelligence (AI) to predict supply chain disruptions, optimise routes, and automate reordering. This AI-blockchain integration helps businesses manage risks and improve operational efficiency. The combination of blockchain with Internet of Things (IoT) technology has improved the tracking and monitoring of products in real time. Sensors embedded in goods or transport vehicles can feed data directly into blockchain networks, enabling automated location, temperature, and condition updates. This innovation is especially crucial in industries requiring rigorous traceability, like food safety, pharmaceuticals, and luxury goods.
Organisations such as GS1 are working on creating global standards for blockchain use in supply chains, particularly in tracking goods and verifying data integrity. The goal is to ensure interoperability between blockchain platforms, enabling smoother data flow across global supply chains. Governments worldwide have recognised blockchain’s potential to enhance supply chain security and transparency. For example, China’s Blockchain Service Network (BSN) is designed to integrate blockchain into various sectors, including supply chains, promoting nationwide use cases and setting global standards.
Blockchain is increasingly used to automate processes through smart contracts, which execute transactions automatically when predefined conditions are met. This reduces the need for intermediaries in supply chains, speeding up processes like payments, order fulfilment, and customs clearance. Blockchain also allows businesses to tokenise physical assets like raw materials or finished goods, which helps with fractional ownership, ownership transfer, or inventory financing. This feature is especially useful in industries like manufacturing and commodities trading.
Software-as-a-service (SaaS) cloud solutions such as Amazon Web Services (AWS) and Microsoft Azure have introduced Blockchain-as-a-Service (BaaS) solutions, making blockchain more accessible to small and medium-sized businesses (SMBs). These platforms offer scalable, cost-effective ways for companies to integrate blockchain into their supply chains without needing in-house expertise.
As businesses increasingly prioritise sustainability, ethical sourcing, and customer trust, blockchain is expected to play an even larger role as the single source of truth in ensuring transparent and responsible supply chains. Its integration with IoT and AI and increasing adoption across industries will create further confidence in its ability to secure critical data.
