Hello
I am creating a dapp on a social network, and I have the following doubts
1. Normally in a normal app (centralized social network) the user data (name, surname, phone, email) is stored in a SQL database, in a dapp the data should be stored in the blockchain?
2. Should I make this type of data to be stored in a traditional SQL database and that the nodes that contain my smart contract insert the data in it?
what is the most recommended?

about 1 no, terrible choice, take a look at GDPR

ok, I understand what you mean because it is dangerous to store the data in the blockchain

every kind of confidential data shouldn't reside on blockchain cause it would make it impossible to exercise the right to be forgotten

perfect, it's clear to me

How do you recommend me to save this data?

traditional db/cloud

ok
Can this information be saved from smart contracts to a sql database?
that is, from the smart contract send data to save in a sql database?

Confidential information should never touch blockchain

Yes, I understand that, but I asked you something else
I can't send the information from the front-end to the smart contract and from the smart contract forward the information to a sql database?

No, if the information passes through a smart contract then you are leaving traces on the blockchain
On the sql database you'd be just storing a replica of what is in blockchain

OK thank you so much

ok then I save the personal information from a centralized server in a traditional sql database and the only thing that is saved in the blockchain, would be the transactions associated with each address of each user, right?
