# 67 Scaling Ethereum after the Shanghai Upgrade

2022 was a big moment for Ethereum, the long awaited MERGE event ended up finally taking place on September 15th, shifting Ethereum from Proof-of-Work to Proof-of-Stake consensus and significantly reducing its energy consumption along the way, a massive step towards Ethereum 2.0.  But there’s still somewhat of a long road of Ethereum updates ahead, including the Surge, the Verge, the Purge and the Splurge, sounds like a 90s rap song but it isn’t, this what it’s going to take for Ethereum to scale and be mass adoption ready. On this new episode of On The Ledger, your host Mo El-Sayed discusses how to scale Ethereum without compromising on decentralization or security, with the Founder of the Aave-Chan initiative Marc Zeller and our Chief Technology Office Charles Guillemet. With a couple of bold statements on Arbitrum and Optimism, sharding and more. Hosted on Acast. See acast.com/privacy for more information.
