It&amp;#x27;s true of Bitcoin but selfish mining is an artifact of Bitcoin&amp;#x27;s sloppy way of estimating how much work is being done, not an artifact of PoW. An enhancement like Bobtail [1] eliminates the incentive to selfishly mine by improving the network&amp;#x27;s ability to estimate the network hash strength.

However, this part is wrong: &amp;gt; Because of finite propagation delays and network packet loss, there are normally multiple valid chains at any given moment in time. How often forks occur is a property of a specific system, not of &amp;quot;blockchain&amp;quot; in general. Bitcoin, for instance, usually does not have multiple chains. They do sometimes happen but generally the orphan rate is quite low. Ethereum has a much higher block rate so propagation delays are more important and forks happen there much more often.
