Abstract
Counterfeit items are a major threat to consumer safety, brand reputation, and economic stability. This study presents a new blockchain-based approach for dealing with counterfeiting by creating a safe and transparent product authentication platform. Each product is assigned a unique digital identifier that links to detailed information safely recorded on an immutable blockchain ledger. Smart contracts simplify authentication processes, allowing users to verify in real time using mobile apps or web interfaces. This enables consumers to make more informed purchasing decisions and builds trust in the supply chain. Furthermore, the system includes the Practical Byzantine Fault Tolerance (PBFT) consensus mechanism, which ensures secure and efficient network agreement. This improves system dependability and fault tolerance, giving stakeholders greater confidence in the inviolability of blockchain-recorded data.
