Remain anonymous and private:
Yoshi coin will offer buyers and sellers the ability to retain their anonymity and privacy, ensuring both their identity and their transaction history remain hidden from public view or even other platform users.
This is from the whitepaper. It is good that buyers and sellers can retain their anonymity and privacy. In this way buyers and sellers will feel more secure without compromising the fact that they are also protected by the smart contract.
Its good that they make the buyers confidential but if the sellers are also anonymity how can they earn reputation? How about the BIG branded names should they still need to hide their identity? well as buyer if I know that the seller is a well trusted brand I will be more confidently buy products from that seller. I think they should also authenticate the sellers so that its easy for the buyers to choose whom to buy.
I think what the word anonymity for this is quite with a different approach. We still know the name of the seller but the seller just uses a pseudonym name to hide his/her real identity. The pseudonym name will still have that reputation because we will give him/her the rating thru that name. Our trust now will be based on his/her ratings like in other existing online business right now, some use pseudonym name but still we buy for them when they are already tested and good testimonies are on their portfolio.
