If the museum does not already have the high-definition digital format of the artwork, it is acquired trough hi-tech cameras or 3D scanners obtaining the highest possible definition.
Then, MIDA creates two digital copies, both authenticated by the right holder of the artwork trough a digital signature. The resulting files are linked to a $MIDA smart contract becoming an NFT.
In the Museums case, one copy remains at the museum for virtual exposition while the other is commercialized via auction. For living artists and galleries the procedure is slightly different with the right owner's copy remaining attached to the physical piece functioning as authenticity certificate.
