today we will have the next HF on the Steem blockchain. HF21 is only a few hours away. I hope we get a smooth run into the new one, not like last time, when the blockchain was mostly unusable for almost a week.
Well, on HF20, the resource credits have been introduced, which was a total different story. The only thing where I see problems is the separate mana downvoting pool. Not with it, as it might be a healthy addition, but on the implementation.
