Reth alphanet testnet rollup built on reth's ExEx execution extension framework. The rollup node runs in same process as the L1 execution engine with fast communication channels (no JSON message passing between them).

Reth SDK making reth far more extensible. Can confirm adding a new tx type to geth is major pain.

This slide says the How but really it's a list of more ExEx Why's 😃

Had to get in the front row for the GIGAGAS talk.

Who needs alt vms when you can just compile solidity to native code?

And of course let's parallelize execution.  Lots of complexities to work through, like special case handling coinbase handling. RISE team to present on this later.

State commitment remains a PITA. But we can parallelize.

Hexary Tries are a PITA. Can we replace them? (Obs a protocol change...)

Zk proving Eth and OP stack block execution  with SP1! .2-.3 cents per tx.

RISE team tells us about why parallel EVM is hard.

2x speed up on average this far. No slowdown in worst case because of lazy evaluation. Speedup with mich larger blocks could be ~23x with independent txs.

Dapps can be designed to make txs more independent.

That's it for today. I may not be able to live-cast tomorrow, though the content looks just as good, only going even deeper.....
