That test seems like a reasonable suggestion; 840GB i= s not prohibitive given today's computing costs. What other than the su= ccessful result of that test would you want to see before agreeing to incre= ase the block size to 8MB?

It's not a reasonable path forward right now given the lack of t= esting done with 8MB+ blocks, among many other problems. A way to help make= that appear more reasonable would be to setup a 8MB testnet as I suggested= , with two years or so of 8MB blocks in history as well as a large UTXO set= to test performance characteristics.

Of course, that'll be a 840GB download - if that's unreasonable you= might want to ask why 8MB blocks are reasonable...
