Vitalik Buterin: @Noahpinion 个别矿工可以拒绝包含他们想要的任何内容，但效果不大；交易刚刚进入下一个区块。 需要 51% 攻击（因此，恢复块，而不仅仅是排除 txs）以完全防止 txs 被包含在内。

原推：@Noahpinion Individual miners can refuse to include whatever they want, but it has little effect; the transaction just gets into the next block.

Need a 51% attack (so, reverting blocks and not just excluding txs) to fully prevent txs from being included.
