I've pointed #3336 towards this branch :)

Before we merge this one into master, we should ensure that we can can still use Verkle, and possibly also use Verkle together with 6110 + 7002.

Ugh.

Now having read this EIP for the first time I’m realizing what a complex beast this is, always considered this more as some „side EIP“. 🤯

@scorbajio Congrats on that, this looks already pretty great! 🤩 Really blown away by the amount of code already touched here!

Not sure if this is going to be before or after ExecutionWitnessBytes in Prague.

[holgerd77]

ExecutionWitness is for Verkle which is not scheduled for Prague, so Deposits can always be placed before ExecutionWitness.

[holgerd77]

The minimumHardfork is not the inclusion HF, but the first HF from which this EIP can be run in isolation (so: all pre-requisits for the EIP are met). So we can (should) switch to Cancun here, just as some additional context.

Implementation of EIP-6110 is being continued at #3390.
