Explore what applying a predicate to the inputs as part of the derivation pipeline would look like. The predicate is defined using evm bytecode and can therefore be quite flexible based on the chain operator's needs. The payload is dropped if the predicate returns false. The chain operator can configure the predicate's bytecode on L1 using the system config contract.

For this to work with deposits, dropped blocks would need to be mapped to deposits only blocks per ethereum-optimism/design-docs#20 |

Description
Explore what applying a predicate to the inputs as part of the
derivation pipeline would look like. The predicate is defined
using evm bytecode and can therefore be quite flexible based
on the chain operator's needs. The payload is dropped if the
predicate returns false.
The chain operator can configure the predicate's bytecode
on L1 using the system config contract.
In practice, this allows for static analysis of the
ExecutionPayloadbefore execution. If some chain operator defined invariant
about the
ExecutionPayloadisn't held to be true, thenthe payload is dropped. This can be used to enforce constraints
on the way that block builders can build blocks.
