Ethereum isn’t here to win the average case. It’s here to survive the worst case. Ethereum is forever. That’s why we wrote the trustless manifesto in the first place - to remind people what Ethereum truly stands for 🚀
“Ethereum was not created to make finance efficient or apps convenient. It was created to set people free” This was an important - and controversial - line from the Trustless Manifesto ( https://trustlessness.eth.limo ), and it is worth revisiting it and better understanding what it means. “efficient” and “convenient

im lowkey insane at making sh*t happen when it needs to. i think that is my greatest superpower. There are a few types of people: 1. Dreamers / visionaries 2. Creators 3. Deciders 4.

The concept of propaganda is terrifying. With AI, facts aren’t even relevant to the story. It’s just whatever some model spits out. No one cares about the truth anymore. And that’s the saddest thing 😢

Yep, distribution looks better. But the open question is still the same: does BuilderNet meaningfully reduce the incentive for private OFA channels? If builders can run parallel pipelines (one inside BN, one outside), then the auction inside the TEE is still downstream of whatever deals were struck off-network.
Still more work to do, but since BuilderNet launched the builder landscape is looking a lot more healthy (last 7d via relayscan)
