Check list:
Confirm the size of the Witness?
For witness data size/networking bandwidth concern, a simple stat of 5% blocks in our testnet shows that normally the witness has ~500M with both storage & stack. like:
block_num=706121, tx_cnt=20, time_cost=0.072s, op_cnt=13241, resp_size=586.9Mb, trans_time=31.27s
block_num=706186, tx_cnt=43, time_cost=0.072s, op_cnt=13236, resp_size=70.88Mb, trans_time=6.166s
block_num=706258, tx_cnt=28, time_cost=0.072s, op_cnt=13241, resp_size=410.3Mb, trans_time=21.31s
but if we don't dump storage & stack, the size reduces largely. like
-rw-r--r-- 1 305M Jul 27 15:51 block_trace_211899.json
-rw-r--r-- 1 26M Jul 27 16:23 block_trace_211899_no_stack.json
-rw-r--r-- 1 264M Jul 27 15:49 block_trace_213673.json
-rw-r--r-- 1 27M Jul 27 16:23 block_trace_213673_no_stack.json
-rw-r--r-- 1 14M Jul 27 15:49 block_trace_214015.json
-rw-r--r-- 1 2.6M Jul 27 16:23 block_trace_214015_no_stack.json
-rw-r--r-- 1 17M Jul 27 15:49 block_trace_226239.json
-rw-r--r-- 1 3.4M Jul 27 16:24 block_trace_226239_no_stack.json
So if a prover has a way to re-construct stack & storage locally, the networking bandwidth will no longer be a problem. Should there be a way as geth does it pretty easy, but it takes some time to impl & integrate into prover bin.
