A blockchain-based application to protect minor artworks

A new emerging trend concerns the implementation of services and distributed applications through the blockchain technology. A blockchain is an append-only database, which guarantees security, transparency and immutability of records. Blockchains can be used in the field of Cultural Heritage to protect minor artworks, i.e. artistic relevant works not as famous as masterpieces. Minor artworks are subjected to counterfeiting, thefts and natural disasters because they are not well protected as famous artworks. This paper describes a blockchain-based application, called MApp (Minor Artworks application), which lets authenticated users (private people or organizations), store the information about their artworks in a secure way. The use of blockchain produces three main advantages. Firstly, artworks cannot be deleted from the register thus preventing thieves to remove records associated stolen objects. Secondly, artworks can be added and updated only by authorized users, thus preventing counterfeiting in objects descriptions. Finally, records can be used to keep artworks memory in case of destruction caused by a natural disaster.
