TTMC is a medical blockchain created through the collaboration between Tsinghua Big Data Institute of Tsinghua University in China, which studies data historical tracking technology, and the University of Tokyo, which holds micro-needle technology. It utilizes blockchain technology to accumulate product and transaction histories, information about the distribution dates of products and services, and provides a big data platform that users can leverage for data. Data providers or data users who provide data can use TTMC Coins as a means of transaction to either supply information to the TTMC platform or receive information from it.
