I hope there are no problems with this sharding, I don't know much about sharding and the benefits in it, looks like it will start on Epoch 77 this week, hope everything will be better after sharding is implemented
Its validation sharding and gives network scalability during validation. Means that there is no roof for IDENA right now. We can welcome everyone who is interested to mine. Unlike pre-sharding days when ~10-15k nodes was the limit and more nodes would crash network.
