TuDoLink is a secure, transparent and decentralised platform where users can share, rent, lease and auction idle computing resources and their data. Researchers and developers save money when using computing power and running experiments; Providers make money when sharing idle computing power or data. Trading on TuDoLink, all parties will, directly or indirectly, contribute to the R&D. This is because our initial buyers will be predominantly scientists, researchers, students, medical doctors and so on. One obvious example will be, if R&Ders need to process big data for a cancer research, instead of paying expensive cloud services or supercomputers, they can simply log onto ToDuLink to buy abundantly cheap or free computing power. Providers are helping to advance cancer treatment research. They may get a free cancer check or health tips from researchers.
