10 years ago, Ethereum lived on whiteboards and in chat rooms. 10 years in the future, it fades into the background - powering wallets, IDs, games, supply chains, and AI systems.

I wake up each day to defend Ethereum’s values and will do so as long as I’m privileged to build at @ethereumfndn. As we move into our next 10 years, Ethereum is the sum of its values. Guard them, plant them them, build with them, or watch them erode. Your choice, our future.

Censorship Resistance.Open Source.Privacy.Security. CROPS are our values. Most users never think about CROPS, until they’re rugged by a custodian or de-platformed. By then it’s too late. Values are like air; invisible until someone cuts off the supply.

Ethereum has no CEO, just millions of devs, stakers, users that are scattered everywhere. They choose to show up block after block, year after year. And they are the ones who keep it resilient, block after block. It wasn’t the lines of code that created Ethereum’s core values,.

Here’s what I think will be announced tomorrow (posting my predictions for fun but honestly I have no idea): . 1. A big new app for builders where they can create new wallets, browse base dapps /farcaster frames, share things in a social feed, and claim onchain summer quests.

A system is only fully trustless if . 1) all logic and enforcement are cryptographically guaranteed and settled on a shared L1 without requiring external validators or honest minority assumptions. 2) There are no liveness dependencies on 3rd parties (i.e. solvers).

EF crosschain interop is loading 🌀.
I am becoming increasingly convinced that the only entity that can solve Ethereum crosschain interop is the EF. There's just no incentive for big players to collaborate. Everyone is building their own fiefdoms as their technological trees are diverging. The EF must hurry to act.

Coinbase will have to compete on market share in the US with Robinhood. This can only be a net positive for the ecosystem.
