I’m clueless about these things - a few questions:

1. Secure offchain transactions (payment networks) - are they impossible if SegWit does not get inplemented?
2. Is there any difference between BTC and XCP? I.e. any scenario where payment networks work for one but not the other?
3. The solution developed by Storj - does it require SegWit?
4. If not, how is the progress, and ETA for mainnet?

I wonder too. What happen when segwit on bitcoin?  
Lightning network and Ethereum contract on XCP?
