@mvines Thanks for review!

I'm testing this locally now with mainnet-beta snapshots...

@mvines Well, I'd like want a rounded number; but I think this should be 11_000_000. The reason is two-fold:

1. Relatively small upgrade time window: 32 hours (*)
2. This happens Friday night in PT

11_000_000 is around 5/13-5/14 around the world (*)

(*):

$ solana  --url http://api.mainnet-beta.solana.com epoch-info

Slot: 9705495
Epoch: 22
Epoch Slot Range: [9504000..9936000)
Epoch Completed Percent: 46.642%
Epoch Completed Slots: 201495/432000 (230505 remaining)
Epoch Completed Time: 22h 23m 18s/2days (1day 1h 36m 42s remaining)

$ pry
[1]  pry(main)> ((10_000_000 - 9705495) / 2.5) / 3600
=> 32.72277777777778
[6] pry(main)> Time.now + ((11_000_000 - 9705495) / 2.5)
=> 2020-05-14 03:37:39 +0900

Ok, I've finished all testing for mainnet-beta. It works as intended. And fortunately we're still in consensus without any bit-corrupt/malicious traces. :)

I've compared two different snapshots from our trusted validators and I saw only the increase of normal accounts and there is no strange owner.

$ grep -E 'owner' accounts1.yml | sort | uniq -c
