I have a question, could a cardano hard fork be created where no one can see the tokens that someone owns in a wallet? To do this, it would have to copy all the code from the blockchain and modify it to make this possible, but by modifying it it would no longer be part of cardano, is there any way to connect this new hardfork with the cardano blockchain? is that the main cardano blockchain continues to validate the hardfork transactions, or would it simply be an independent and divided blockchain but similar to cardano?
