Hello. I am from F2Pool. We are currently mining the biggest blocks on

Thanks for giving your opinion!

 
Bad miners could attack us and the network with artificial
big blocks.

How?

I ran some simulations, and I could not find a network topology where a big miner producing big blocks could cause a loss of profit to another miner (big or small) producing smaller blocks:


(the 0.3% advantage I DID find was for the situation where EVERYBODY was producing big blocks).
 
We think
the max block size should be increased, but must be increased
smoothly, 2 MB first, and then after one or two years 4 MB, then 8 MB,
and so on. Thanks.

Why 2 MB ?   You said that server bandwidth is much more expensive in China; what would be the difference in your bandwidth costs between 2MB blocks and 20MB blocks?

Perhaps we should arrange to run some more 'simulations' with miners from China and elsewhere?

Let me know there's interest to do.
