  With the increase of web users and applications with real time requests, the
ability to identify, track and trace elements of a product as it moves in the
supply chain is deemed necessary, and for many industries is even mandated by
national or international regulations. Traceability presupposes the integrity
and transparency of data that is saved and shared. This is a problem for
current technologies, as there are many examples with tampered data and
database vulnerabilities that resulted in serious implications and data loss. A
solution to this problem can be the decentralization of the system, which will
remove the central point of failure. To that effect, blockchain or DLT
technologies, an emergent technology that enables the decentralization of a
network can be used, by implementing a trustless model to achieve it.
Blockchains are tamperproof and transparent, which means that by exploiting
blockchain characteristics, traceability can be improved. A model that
describes the decentralization process of the supply chain traceability part
has been developed for this paper and is later evaluated and compared with the
traditional system.
