Hello,
There has been a lot of talk about the fork that happened, just to recap, the checkpoint server was attacked but we got it fixed right away. Resynching the wallet from scratch (after backing up your wallet.dat) will fix things, but to prevent this from happening again we have set up extra seednodes and beefed up the checkpoint server. We have also compiling more defenses against this in this new win wallet:
https://github.com/graphdev/releases/download/v1.1.0.1/windows-graph-qt-v1.1.0.1.zipPlease remember to type 'repairwallet' in the console once you have moved to the new wallet. There is still a risk that your coins may be lost forever, if you sent to an exchange on the wrong fork. Please make sure that you are on the same block as the explorer:
http://explorer.graphcoin.co before sending any coins.
We will have the enhanced functionality Mac wallet with the new updated seednodes compiled shorty. There will also be a sneak peek of what the arbitrage bot will look like once we feel enough people have downloaded this new wallet.
