This looks like it's supposed to be a Bitcoin-like system that sends newly-printed crypto-tokens to users who exercise. How does the blockchain know who exercised? The user's FatBat device tells a server that the user exercised. The server tells the blockchain who the newly printed tokens go to. There are some big trust problems: - Trust the user not to attach their FatBat to a drill to trick its sensors into thinking the user's exercising. - Trust the user not to hack the FatBat device (physically controlled by the user) so the device lies about how much the user exercises. - Trust the communication channel between the server and the FatBat can't be proxied or intercepted. - Trust the server doesn't lie to the money-printing part of the blockchain about who exercised, or how much they exercised.
