The results from our 2025 Ethereum Institutional Staking Survey are in. Our latest report compiles them to reveal where ETH staking is headed next. TL;DR Institutions want to stake securely with next-gen infra and the next chapter in staking will ensure Ethereum wins. [1/5]

99.5% energy reduction in an instant? My guess is much closer to 99.95% less energy consumption than with PoW. The AI industry is thankful for all the spare GPUs to train models (cheers to 3 years of tech breakouts in AI). #Ethereum
Three years ago, we activated the merge. It was one of the wildest and most exciting times in Ethereum's history. Watching the network seamlessly transition to proof of stake while staying live felt like witnessing magic. 99.5% energy reduction in an instant. Thousands of GPU fans went silent. Years of work crystallized in a moment. I'm so grateful to have the privilege of calling myself an Ethereum Core Developer and getting to work with some of the best folks in the world.

gm frens! Long time, no see 😉 You’ve been eagerly waiting and guessing, and the moment is finally here: We’re thrilled to finally announce EthCC[9]! This past edition was filled with excitement, a lot of heat and plenty of sweat. We had a chat with the sun and mutually decided that it would be best to shift our dates to a slightly cooler (but still gorgeous) time of the year ☀️ So, drumroll please, EthCC[9] will take place in Cannes from… 📅 March 30 to April 2, 2026! Mark your calendars, get ready and stay tuned for more info! 💙❤️🩵
