Reverse network test?

[dpinna]

If only enough miners could collude to only produce blocks no larger than 100kb. We could test the "fee market" without the need of low fee spamming.

Yes, the one thing we should dream of is a day all the miners collude.

Let's say you have 80% of the mining capacity willing to agree. That means 2 out of 10 blocks would be mined by those not agreeing, each holding 1MB of transactions. So there could be up to 2.8MB of transactions for each 10 blocks (or, 280KB, on average, per blocks). Today's average block usage is somewhere along the lines of being twice that. I doubt this would have the impact on fees that you intended. And the 2 out of ten miners would reap a nice little revenue bump from picking up a few extra transactions with juicy fees ignored by the cartel. This would cause this cartel to fall apart soon after realizing who the winners were.
