    Ethereum core devs have a call coming up this Thursday to discuss getting EIP-4844 to be considered for inclusion (CFI). This is a huge moment for the many teams that have been working on getting this EIP to production this year! Here is why I think it's time for CFI 👇

    Optimism just enabled 4844 a few min ago. From $0.32 to $0.0004 for a transaction! Will rise over time as blob congestion picks up; but looks incredible to see how cheap we can make Ethereum!

    Yesterday, it was decided that EIP-4844 will be included into Ethereum! It will be in fast follow hard fork after Shanghai. This is a huge win for ethereum and makes me so excited for the future of blockchain scalability! Here’s what’s next👇

    EIP-4844 is more than a tech upgrade. It’s a substantial shift in how Ethereum core dev works at all, improving the relationship between research and client teams, and welcoming L2 core devs! It might be the most important moment in the transition to the rollup centric roadmap!
