Does it cost gas to access data stored on the IPFS with a smart contract?
IPFS is not a miracle worker. It is simply an external provider which is 'convenient' to use with Ethereum smart contracts. … The only difference is the IPFS usage costs, but that has nothing to do with Ethereum per se.
The gas cost for using IPFS is the cost of storing the hash and whatever else your contract needs. …

Would it make sense to use a SQL database to store the data of a Dapp?
One option is to encrypt the data and send it to the smart contract. The data would be decrypted/encrypted only outside the blockchain. Disadvantages are:
The smart contract can't read the data as i …

Key-value immutable storage: on-chain vs IPFS
IPFS hashes are immutable so those should be on-chain.
As you have noticed, you will face problems with accepting 8 strings as a parameter. … I'm assuming your address[] pictures refers to the IPFS hashes? They are not of address type, but of type string - or even better - bytes32. …

Does it align to the base concept of blockchain, if one stores the hash value generated from...
Contrary to popular belief IPFS doesn't make anything decentralized, per se. … The protocol enables decentralization but in reality if you upload files to IPFS it's all centralized: the data resides only in the IPFS nodes to which you upload it to. …

How fast and scalable is a Dapp build on ethereum?
The idea also somewhat works except when there are sudden spikes in network usage.
2) Ethereum does not use IPFS as such. … IPFS is one option for storing data and is quite popular among Ethereum Dapp developers because Ethereum itself is quite bad for storing data inside its blockchain (it's very expensive).
3) Running your …
