Gene-chain is a marketplace where supply and demand of genetic information come together. The goal is to facilitate the search for, or sharing of, saving, buying and selling of genetic information. If someone has once taken a DNA test, they can offer up their genetic information on the platform. Researchers can filter the platform for certain conditions the genetic material they seek must have, and can buy it with DNA tokens, the own cryptocurrency of developer Encrypgen. Researchers mostly need genetic information for research into new medicine. Gene-chain brings supply and demand together through a blockchain- secured environment in which everyone can participate. This creates an easier way to collect data for research, which can lead to more efficient and expense-saving new treatments. The seller controls what is or is not sold.
