High load on the network

Now I wondered if a stress test of the load on the network was carried out?
I mean a large number of transactions per unit of time.

How much will the transaction fee change and possibly the waiting time?

That is, if GRIN becomes digital cash in the future, will a large volume of transactions be a problem for the network

Grin can do maybe up to 30 layer 1 transactions per second. So it is not going to replace Visa.

Grin support basic Lightning channels. Although we will not need lightning channels for a very long time, the devs made sure to bake in relative time-lock that is needed for lightning channels in the 5th planned hard fork. So Grin is future proof :slightly_smiling_face:
