Alephium’s sUTxO already does this in production: UTXO for assets + dynamic state for contracts + composability. Best of both worlds, live today.
Bitcoiners deserve a lot of credit for pioneering many of these ideas (see Utreexo).
But yes, this is what the current proposed Ethereum scaling strategy looks like in action.
We want Ethereum to have the best of UTXO-style state, dynamic state, and everything in between, allowing the great majority of Ethereum's activity to be hyperscaled without sacrifice to decentralization, ease of node running and censorship resistance.

If you’re a testnet person, this is for you.
PoWFi just went live in a public testing environment - and it’s meant to be stressed, attacked, and broken.
This isn’t about polish. It’s about battle-testing.
Let’s see what breaks.

I spent this weekend with @_polto_ at Neuchatel, at our very own private @SeedSigner<>@alephium hackathon. We're cooking something fun 🫕 Updates to follow up soon!

1/N Bitcoin Takeover S16E61 w/ @aszpieniec
This episode makes a strong case that Bitcoin’s transparency is no longer neutral.
It’s becoming a protocol-level risk.
