I. situation

About 11h ago, there were first reports of Gridcoin users being on a fork :-(

Looking now at it, the block that "split" the other chain(s) seems: 1046801

output from IRC:

• !verify 1046800 e20a0e5c04c987942f7a557ec2b06a220a6c0dfb504f4db7de2719b8c436cf5e
•    fediverse: => CORRECT: the given hash (e20a0e5c04c987942f7a557ec2b06a220a6c0dfb504f4db7de2719b8c436cf5e) belongs to block 1046800

•   fediverse: => WRONG: block 1046801 has this hash: 2b3ce5374983ba1c47ef6dd078e28e1d29a590e23a3690d19c0a1c4e84d4e8a6

II. Please verify your block hashes below, so we stay together!

                   (e.g. type in your Gridcoin wallet's debug menu: getblockhash 1047690)
 

• When your hash doesn't match with below hashes:        
  • try a restart of the client (see here why).
  • If that did not help: come first to IRC and we'll guide you (e.g. let you do a reorganize (see: (A)), this will likely take less time than doing a blockchain rebuild)
  • You could also try from the Gridcoin menu:  Advanced » Rebuild Block Chain  (you can also apply the snapshot/bootstrap and make also a !backup of your important files first)

Typing "reorganize e20a0e5c04c987942f7a557ec2b06a220a6c0dfb504f4db7de2719b8c436cf5e" (without the "s) in your debug console should bring you to block 1046800, and hopefully you get back to our chain. Compare hashes above, please.
