Incentive designs that pay for a proxy
A reward for a measurable stand-in, not for the service a customer wanted.
What to keep
Helium's coverage proof can be satisfied by radios that hear each other. Hearing is not the same as useful paid traffic.
Any DePIN or mining design that pays for a proxy will be farmed at the proxy.
Read the reward function before you read the map of devices.
What this is not
Not a complaint, not a price chart, and not a complete history. Primary sources outrank this summary.
