Digital Twin by .ART is a digital letter of authenticity that is simple to register and impossible to lose. In just a few clicks and without the need for complicated legal procedures, one can create a letter of authenticity for a piece of art that can be printed anywhere, anytime – thus making it easier to sell, create records of related transactions and track provenance. Leveraging the easy-to-understand technology of domain names, using an international standard for describing cultural objects developed the J. Paul Getty Trust, and offering the option of a Blockchain connection, Digital Twin by .ART creates a sophisticated but easy-to-use art object identification tool. Having all the qualities of a paper certificate of authenticity, Digital Twin by .ART lets one store unlimited video, graphic, text and other types of data. This puts the given piece of art in the context of creation and increases its value since the most marketable part of it is information and emotions, not the physical component. Digital Twin by .ART was developed using the digital infrastructure of Alibaba Cloud, the largest cloud computing company in China.
