I am going to make multiple comments here as I have many things to discuss.
There are many people who regularly brings up the fact that the record making blockchain that can be scaled to do 100,000 Tx/s
This brings a simple question to my mind .... is there a means to performance test the blockchain while its in the testnet or so ?
I don't know for sure. Waves platform did something to test their network. IOTA had a mess. So I think you should be able to do some testing by spamming the blockchain with Tx.
