For now, we have to deal with this issue with the checkpointing server. The other day when the block explorer halted, that's when we noticed an attack on the main node which put server resources (memory, swap, and cpu) at 100% so we had to restart it. This caused a fork, but we fixed it within 30 minutes. Some of you may be on the same fork as the attack, which is easy to fix.
Check http://explorer.graphcoin.co/ and make sure your wallet is on the same block as this, if not, you will need to back up your wallet.dat in the %appdata% directory and then delete everything except your wallet.dat and resync.
The main checkpointing server is built into the wallet, but if you want to be extra careful, you can put:
addnode=explorer.graphcoin.co
addnode=62.116.254.204
To your .conf file
Right now we are going to send Bittrex a support ticket to get this resolved.
It also seems that though i have cleared out all the files in my %appdata% folder and re-synced i am still missing around 2k coins if i compare my balance to the block explorer.
Also why is the bittrex wallet for GPH showing as inactive???
Whats going on ?
Any thoughts ?
have you tried "repairwallet" ?
