But yet, Googling the function names as well as the
Stellar del Futoro (the name of the Ethereum token) yells no website at all whereas an ᴀʙɪ file is required to use such kind of smart‑contract and since it’s not on Etherscan, it needs to be on a website (obviously the one from the organization managing the project).
So the best way to get more information would be to ask some users at random. The Ethereum system allows to send data to anyone in hex, which means using numbers and the letters from A to F (even using spaces is impossible).
Now that I explained the purpose, the part which isn’t related to technology (and can be used in other contexts like in the street) : how do you tell to someone at random you want to ask him/her a question using numbers and the letters from A to F in a way he/she recognize this isn’t just like that but this is text and that you want a reply ?
The purpose might be on topic but the question is: What if for a different reason it would had to be done using a paper?
