Body chain: using blockchain to reach augmented body health state consensus

Humans have used prosthetics for a long time, especially to recover lost abilities such as eyesight with glasses. We foresee a near future where more and more human organs and parts will be augmented by implants with computing, storing, and communicating capabilities. Unfortunately, those distributed augmented parts may be attacked, for example, by viruses, and they might have difficulties reaching consensus on the real state of the body's health and which actions to take to try to recover. We propose to use Distributed Ledger Technologies (DLT) such as a private blockchain based on practical Byzantine Fault Tolerance (BFT) algorithm to reach body health consensus between those major, augmented body parts. In doing so, given the BFT algorithm formal guaranties, the augmented body can still rely on a correct body health state if less than one-third of the body parts fail.
