Let’s breakdown what we know…
With 75 second block times we have 1152 blocks per day. Zcash has a blocksize limit of 2MB.
Shielded Orchard transactions are 9.1KB (2in, 2out). That gives us a theoretical max of ~219 shielded Orchard tx per block and theoretical max of ~252,000 shielded orchard tx per day.
How many of these non-spam transactions (i.e. historic average input/output) would cause issues for the network in a similar fashion to the ongoing spam attack? Can the network handle the theoretical max number of shielded Orchard transactions per 2MB block?
Again, what type of performance testing results and scaling plans can be shared by the ECC, @nathan-at-least ?
