The problem lies in how to prove the physical activity and ensure that it is not tampered with, in the end either you will trust certain sensor devices (and thus the currency will be central) or you will trust any sensitive device (each sensor has an error standard and may increase or be manipulated) and so the activity The physicist would be useless.
The best you can have is an interactive game in which data is recorded in central servers, validated and then individuals are rewarded with dollars or cryptocurrencies.
The verification will be done through visual and audio recordings and converted to nft, ai will verify activities. I need a qualified coder who is able to code such a algorhitm.
+ What is the role of NFT tokens here?
