On September 15th, 2022, Ethereum became a proof-of-stake network. On today's episode Andrew and Alex break down what happened, how it changes the investment case for Ethereum and what it means for the future of Web3. The significance is hard to overstate: by some estimates this will reduce Ethereum's carbon footprint by 99%. It will clear the deck for future upgrades to make Ethereum more scalable and useful. It will radically alter the supply and demand dynamics and may make Ethereum a high-yielding deflationary asset, attracting new kinds of financial investors. It will provide clarity to enterprises who want to build on public Web3 infrastructure. It could even improve the image of blockchain technology, easing pressure from policymakers. They also discuss the impact on cryptoassets as a whole, how it could impact Bitcoin and what it means for alt-L1s.
