"Honest-but-rational or ideologically motivated validators could use this attack to increase their profits or stall the protocol, threatening incentive alignment and security of PoS Ethereum. The attack can also lead to destabilization of consensus from congestion in vote processing."

Part 2!

Today we're reading through a recent paper that pokes some serious holes in the security of Proof of stake Ethereum. As we get closer to the merge, it's more important than ever to understand the different attack vectors on Ethereum, what the consequences are and how likely these attacks are to come to fruition.

This readthrough is dense and build on previous episodes we've done, so if you haven't been a long time listener, go back and listen to these first, otherwise it will be hard to understand:

1. Why Proof of Stake

2. The Beacon Chain Ethereum 2.0

3. What is Byzantine Fault Tolerace

4. Flashboys 2.0
