Did you even read the images ? they used ERC20 as their base for their project, why ? because it is very easy to create one and it is cost-effective compared to build up a new kind of project with a different/new algorithm.

You said you came from STATESTREETE corporation, mind to tell me where it is ? link to your corporation profile please ? because i searched for it and i got none. Not sure whether you were misspelling it or it did not exist in the first place.
