Rough estimate would be the upcoming Sunday/Monday.
I remember you being a DRK holder back in the day so perhaps this question is relevant to you....
What happens if not everyone updates to the new SDC client before block 257,000?
I remember when DRK had big problems (forks, etc) when people did not upgrade as requested. I know this is a different situation (PoS vs PoW and no masternode payment issues etc) but I am still curious on how the SDC network will be impacted if not everyone updates in time.
I assume at least a few people will not either because of laziness, or not being online to see the update this week.
What is the worst that could happen if people to not update on time?
btw I am pleased with the code I see in GutHub. Going open source sooner rather than later for most of the newest update was the right decision. Thanks dev team!
