如何设计DAPP区块链EVM应用程序？

Question

I am developing the blockchain based application it is basically a ledger system to track who owns the item now. I want to ask where that item information comes from will it be keep in some centralized database and then I will do the tracking of that item/product in blockchain ? And Where do I keep the customer or CSR user in blockchain or it will also be keep in database what about their private and public key. where do I keep it in RDB? Is this the right approach . Kindly help thanks..

Answer 1

Storing data in blockchain is expensive. Secondly blockchain is a public ledger of Information, which means whatever you store in blockchain can be seen by anyone so storing personal data in blockchain is not a good idea.
