I wanted to follow up on my [post from last week](https://steemit.com/gridcoin/@scalextrix/gridcoin-difficulty-increased) about the number of GRC staking since the upgrade to 4.0.0.0.

I had not reached a conclusion then and so I feel its reasonable to repost on the subject, but Im not going to do this weekly, I promise.

Without further flim-flam, lets take a look at the results for the last 7,000 blocks:

# Number of addresses that are staking
Slightly down from the last two results at 2215, maybe we saw a slight bulge around the upgrade which is natural I suppose as people brought wallets online for the upgrade

# Number of GRC staking
148 Million GRC; A bit (5 million GRC is a bit apparently!) down from last week at 153 Million GRC, but still way higher than the first week at 104 Million GRC from before the upgrade

# Conclusion
Im ready to call it, you'll notice this time I described it as an upgrade, and I do really think it is.  Gridcoin just got significantly harder to attack over the last few weeks, because more GRC is online and staking more of the time.
