The general objective of the project is the design and prototyping of an integrated solution to support the traceability of the wood supply chain through the use of blockchain technology, supported by advanced anomaly detection techniques for quality assurance. The use of blockchain technology in the wood supply chain offers a potential competitive advantage to ensure maximum transparency in every phase of production, from the selection of the raw material to the processing and marketing of the product, making the entire supply chain visible. This allows consumers to have access to certain and certified information, eliminating doubts about the origin and quality of the product. Blockchain technology can be considered a winning solution to support the wood supply chain because it guarantees properties of immutability, traceability and availability of the data. As regards immutability, this technology guarantees that what is saved within its ledger cannot be modified later and unilaterally, or alternatively that all changes to the data are stored in detail and are easily identifiable. Saving information in blockchain also ensures the traceability of the information, that is, to clearly and incontrovertibly indicate who entered the data, thus making them ultimately responsible towards the other participants in the network. Finally, given the independence of the nodes in the network, the availability of the data is not tied to a single subject who holds ownership of it at will. Finally, in order to ensure the quality of the data saved along the supply chain, these will be analyzed using advanced machine learning techniques, in order to identify any anomalies and explain or prevent their possible causes promptly (explainable artificial intelligence).
