Hello developers!
Today one of the interviewer asked me about how to store client datas privately while using ethereum public Blockchain..
For example if client is running a hotel business but he wants to use smart contracts for his business but he don't want to expose customers details on the public network then how he can achieve this..
Any ideas??

bc is not bout privacy

Yeah ethereum public network is all about transparency and open network right so he can't store clients details privately if he wants to use public network..

He could encrypt it, not sure if it's a good idea tho

Sry, Bc means?

blockchain

Might be but if he don't wants to show sensitive information then using blockchain isn't worth it.. he might try to use other alternatives i think..

bc is hyped theme and minting nft as tickets will give them tonn of hype

So storing sensitive information on databases like sql, mangodb or firebase and linking transactions with smart contracts right??

ye, i think its optimal case
+ hash of documents or id to tie to base
+ hash of documents or id to tie to base

You should still encrypt it storing in a db tho, if it's sensitive

This looks like exactly what I was looking for, for plain text seeds. Thanks so much
Still need to find a way to get this from ledger though

Look into their developer documentation, on how request addresses. Lots of wallets can do that from ledger, so it's possible
