    In the wake of revelations about ConsenSys, I did a deep dive and discovered that Ethereum has been collecting Ethereum addresses for every. single. transaction. It gets worse - the addresses are just SITTING on a PUBLIC ledger, and will NEVER be deleted. What is going on??

    A builder-searcher paid 16.8024 ETH to build block 17195495 so they could arbitrage 36 different Uniswap v3 pools. All this happened in just 12 seconds. Still think LPs are not getting rekt?

    The @Rook relay is undergoing load testing now. We will never vertically integrate with a builder. The relay is neutral infrastructure, and allows the user full choice to broadcast to any combination of builders.

    It's a failure of the Ethereum ecosystem that one month after the merge, there is still no neutral relay. All the relays that exist are vertically integrated builder relays.

    We will push so much economics talent onto Ethereum that it becomes the golden career path for every top performer in the field. Would you rather work on stocking warehouses for Amazon, selling ads for Google, or designing a programmable global economy at SMG?

    Smart people from academia are moving into brypto research. On the one hand, this gets me worried - the field is becoming more competitive. On the other hand, we are well prepared. We have Uniswะฐp puzzles, we have brain teasers (do you tie shoe laces on or off the travelator?),

    Real CEOs are falling asleep under their desk covered in arXiv printouts on constant volatility CFMMs. I don't even know what Ibiza is. Sounds like a zkRollup.

    I need devs to stop building. I can't take this anymore. Every day I am checking and it is different tech. Every day, check CT, new tech. I can't take this anymore, I have over scheduled, by a lot. It is what it is. But I need building to stop already. Can devs DO NOTHING??

    Don't want to believe this. @0xttk was one of my first mentors in the industry. He encouraged change at @Rook and encouraged me personally, when I was coming up as CEO. We hadn't spoken recently. There was always tomorrow. I feel devastated for him and his family.

    1/ Important to note that these screenshots don't really tell a complete story. But, it's hard to watch people who are open and welcoming and available, not even being afforded the respect of being told that the questions are to benefit a rival software client.

    You find the file mev.vim on a laptop abandoned at the local sauna. What are the contents of the file?
