How will Ethereum stop evil-miner attacks where a gas-guzzling tx is added to a just-solved block to slow down competition once gasLimit goes high ?

For relevant discussion see this reddit thread, however from my perspective No satisfactory answer was provided there


  • Thanks for pointing out the question here. Vitalik's answers in the quoted reddit thread may be the most satisfactory for a while...

There is no way to prevent such behaviors once the gasLimit is large enough to affect others. I guess the only solution is to guarantee the gasLimit to be reasonably small for most of the miners. However, there is a catch. How do you know how much is small?
