'Can I use Ethereum offline for data sharing?

I'm going to share file based on blockchain, but because I decided to build a private network I need to design a offline blockchain.

I looking more and more in the internet, but I can not find a solution to use offline blockchain.

Most of offline dApps are a complicated matter because most blockchain networks rely on internet connectivity to operate. The network exchanges data to verify user funds and issue transactions quickly.

Should I design a offline network for this purpose or there is a offline Ethereum? And if is exist, do it work without any problem?
