abstract = {Supply chain management enhanced by the Internet of Things (IoT)
solutions integrate special tags (e.g., RFID, NFC, and QR-codes) with
products to create Smart Tags, in addition to storing supplemental
information about a product, which is also used to track products during
their lifecycle. However, a product consumer has to implicitly trust the
Smart Tag creator and other stakeholders within the supply chain that
they are providing authentic data within a product's tag. The DL-Tags
solution steps into this environment to offer a decentralized,
privacy-preserving, and verifiable management of Smart Tags during a
product's lifecycle. The solution is based on distributed ledger
technology (DLT) and uses the Ethereum blockchain to mediate
interactions between the stakeholders during a product's exchange
process. By reaching a consensus on the product's description and state
logged on the blockchain, all involved stakeholders and product
consumers can verify the product's authenticity without revealing their
identity. The paper describes the DL-Tags solution and includes a cost
analysis of all implemented transactions on the Ethereum blockchain. The
proposed solution provides evidence of the product's origin and its
journey across the supply chain while preventing tag duplication and
manipulation. It is among the first documented practical solutions using
DLT and IoT for supply chain management, which is designed to be
distributed ledger agnostic.},
