I was talking about halving the difficulty after 20 minutes without finding a block, so from (say) 500M to 250M instead of the current 1.
I'm sure you'd have people rushing to submit 20 mins + 1 second blocks they had already solved. *shrugs*
I think removing the 20 minute structure period would prevent all of this.
It's a rush to race against that timer, make the timer go away and the network should flow(?)
I think LoyceV's proposal does not depend on the block timestamp but rather the node's clock, which obviously is going to be even easier to abuse since tempering with clock time is fairly easy and takes no work.
No matter how you look at it, you really can't solve testnet, even my proposal which is the most extreme of them all might not work, some jerks are willing to lose money just to upset someone else.
