The Ethereum Mainnet merged with the Beacon Chain proof-of-stake network on September 15, 2022. This marks the end of proof-of-work for Ethereum and a full transition to proof-of-stake. This historic upgrade is projected to reduce the Ethereum network's energy consumption by over 99% and sets the stage for future upgrades to further scale the Ethereum network. Holders of this POAP were there to witness the Ethereum Mainnet Merge with the rest of the community and signaled their support to the core developers of this enormous undertaking by sending roughly $10 of ETH to the Protocol DAO, directly funding protocol contributors. Special thanks to all of the client teams, researchers and core developers of the Ethereum Protocol, and to community leaders The Daily Gwei, Bankless, Ethereum Cat Herders, The Ethereum Foundation and EthStaker for their support in preparing the world for this moment. -https://thedailygwei.substack.com/ -https://newsletter.banklesshq.com/ -https://www.ethereumcatherders.com/ -https://ethereum.org/en/ -https://ethstaker.cc/
