Imagine a world where people earn income by taking weekly blood tests and send daily selfies to a database. The government, as well as private software companies, pharmaceutical companies, and research universities, buy this data to develop drugs and anti-aging products. The more valuable this data is to these companies—like pictures of the skin, face, or "hidden areas" of the body—the more income a user earns.
This is the future being pitched by pharmaceutical company Insilico Medicine, Inc. and blockchain mining and management company The Bitfury Group, who want to pay people in a cryptocurrency called "LifePound" in exchange for voluntarily turning over medical data. The data will live on a blockchain, a digital log that uses every computer running the software to store unaltered information, theoretically forever.
