Basic Implementation

This is the authentikeos smart contract's logic. All it's doing is requesting the permission level. For other DSP services other advanced logic can also play into satisfying a request such as:

1. Owning an NFT

2. Holding or Staking another token

3. Having the playload signature match a static checksum
