Abstract
Using the Ethereum Merge upgrade — a transition from Proof-of-Work (PoW) to Proof-of-Stake (PoS) — as a natural experiment, this study identifies a cooperation channel driven by informed PoS validators, in contrast to the energy-intensive competition among PoW miners. We document that PoS achieves more efficient consensus through shorter block times and higher transaction throughput, and find increased informed trading post-Merge. Our findings suggest that PoS achieves enhanced economic efficiency through informed validator cooperation and stake value maximization.
