Enterprise blockchain technology in combination with sensors and Internet of Things (IoT) devices is a cost-efficient foundation for supply chain transparency. This shared, near-real-time record can now be recorded and accessed by members of an ecosystem and shared with customers. This allows verify the authenticity of products.
Centralized systems use barcodes, unique electronic product codes (EPC), and RFID technology to track items through the supply chain. These systems, however, rely on centralized certificate authorities and centralized databases and so are fundamentally insecure since they have single points of failure that make them susceptible to cyberattacks and insider fraud.
Decentralized and immutable blockchain systems allow product tracking to its origin (traceability) and through every step of the supply chain (authenticity). The dApp enables a user to scan a QR code on the product which provides a full trace and validation of the productās authenticity.
Such an approach tracks the product or a productās components through every step in the chain, for example via an embedded RFID or NFC chip. At each step in the chain, the RFID chip is scanned, a smart contract is executed, and then multiple trusted nodes verify the information is correct before it is written to the blockchain ledger. Each entry in the blockchain ledger is cryptographically signed and encrypted which deters fraud and reduces the chance of hacking. Since the entire supply chain process becomes transparent, it becomes possible to quickly and inexpensively validate product authenticity. Any product that doesnāt enable dApp-based authenticity then becomes suspect which disincentivizes fraud.
Provenance takes authenticity one step further by also providing information about the entire history of a product through the supply chain. So, for example, the location history, the custody history, and the environmental conditions during the journey can be tracked and stored immutably on the blockchain. This type of information ā GPS coordinates, custody IDs, temperature data, accelerometer information (for damage assessment) ā is typically provided by Internet of things (IoT) devices. These devices send out data streams that in combination with decentralized consensus are then written to the blockchain. Since blockchain technology reduces verification costs it will likely gain widespread adoption and so make checking product authenticity and provenance commonplace.
By streamlining and automating these processes with blockchain, transactions can be completed faster and more efficiently. Since record-keeping is performed using a single digital ledger that is shared among participants, you donāt have to reconcile multiple ledgers. And when everyone has access to the same information, it becomes easier to trust each other without the need for numerous intermediaries. Thus, clearing and settlement can occur much quicker.
I am interested to hear your thoughts on how implementing blockchain would benefit this company.
