XIOS is still alive and undergoing a rebirth.
Please join the Discord channel for further info.
I'll do my best to cross-post recent developments.


The last fork (yesterday) will require a resync from a recent blockchain which you can find here:

Delete all the files (in %appdata%/XIOS/ for windows, /home/user/.XIOS for linux) except XIOS.conf, masternode.conf, banlist.dat and wallet.dat
Then, copy/paste the files from the archive and restart the wallet.
If your coin balance is wrong, type "repairwallet" in the debug console and restart the wallet.

The current working and actively maintained block explorer is:
