• verify your block hashes

If you want quick help: 

• come to IRC channel gridcoin-social (via browser, more info here):

and use e.g. fedi's command: !diff

I. situation:

• 22:15 (Sep 10, UTC+2): a minimum of 36.5 million GRC (=9.2% of all coins) are securing the Gridcoin network currently: block 1018285, net weight: 12.7 mio, difficulty: 3.823 -> further info here

• 10:50 we fell again below 5 million :-(
• 10:38: We're now back above 5 million net weight (minimum: 4.76 million)! Let's see when we reach 11-13 million again :-(
• 2017 Sep 10, 10:17 UTC+2: 38% net weight drop in 95 mins
• 36% drop in 60 mins

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

                   (e.g. type in your wallet's debug menu: getblockhash 1023948)

• When your hash doesn't match:  
  • 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, 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)
