How Does the Shift to Proof-of-Stake Affect MEV and Front-Running Dynamics?
The shift from Proof-of-Work (PoW) to Proof-of-Stake (PoS) changed the role of the block producer from a miner to a validator. While the fundamental ability to reorder transactions for MEV remains, PoS introduces new concepts like proposer-builder separation (PBS).
PBS aims to decentralize block production, making it harder for a single entity to control the entire MEV supply chain, thereby potentially mitigating centralized front-running opportunities. However, it also introduces new centralization risks among block builders.
