I can't seem to find a straight answer to this question. I know that Uncles are rewarded, but are they used to help secure the network? Or does Ethereum use the longest chain rule like Bitcoin?

  • Hey Lauri, thanks for the comment, the answers were kind of conflicting on that post, but i found a clear answer when I took a look at the EIPs on GitHub. – Beez Apr 7 '20 at 5:16

Update: After EIP 100, uncles are included in calculating the target difficulty, meaning they are a factor in determining the overall PoW on a chain.
