In the BitShares blockchain, every hour there is a maintenance interval where some complex calculations take place. Those calculations are too time consuming to be done by the Delegate (block producer) in the allotted time slot. So every hour there's a small period where some heavier computations take place, bringing the whole system up to date.
I'm wondering why this isn't in Steem? Is there nothing requiring complex computation on the Steem blockchain? What about EOS?
Any techies out there with the answer?
