CFB is getting ready to release a coin from scratch to support his JINN hardware project for a decentralized IOTs.
Sounds great
if IoT wasn't a code word for giant surveillance grid of doom. Yes, this is the type of structure things like unmanned cars will be built around. People will be required to carry devices to travel on public infrastructre, maybe a cell phone type device that acts as a transponder. In addition to their sensors simulating sight, unmanned cars will detect the RF from the device and act as a collision avoidance plus navigation system. Your wallet and identity will then be connected to the same transponder. Everyone will be tracked like cattle.
Manual driving will then be banned, cash ban, then increased negative interest rates. At this point, they're just getting started because the world needs to be reduced to pre-industrial revolution population. Best case scenario, the west will resemble China, but probably far worse. Even if you agree that humans are some type of disease that needs to be contained, most people of European and Asian descent are basically at negative birth rate already. You can either create a world-wide prison grid system for everyone that utilizes socialism to supplement people who are simultaneously pushed out by technological unemployment and still over-reproducing at the same time, or you can just address the main offenders of high, out of control birth rates.
So yea, there is really no such thing as a "decentralized IoT". All it is, is a system to broadcast as much personal information as possible to be centrally administratively controlled.
