To cover the entire SlotId (uint256) address space, each validator must validate a portion of the SlotId space. When a slot is filled, the SlotId will be put in to a bucket, based on the value of the SlotId and the number of buckets (validators) configured. Similar to `myRequests` and `mySlots`, a function called `validationSlots` can be used to retrieve the `SlotIds` being validated for a particular bucket (validator index). This facilitates loading actively filled slots in need of validation when a validator starts.
In Codex's integration tests we now create real ZK proofs,
which take a bit longer to generate. We therefore need a
period that remains the same while the proof is generated.
Rationale: it was already a very thin wrapper
around Marketplace, and now that its remaining
functionality has been moved to Proofs and
Marketplace, we no longer need it.
1. Replace all instances of `now()` with `await currentTime()` to get a more accurate representation of time from the block timestamp. Update examples.js to be async.
2. Move `RequestState` to `marketplace.js`
3. Delete `TestStorage` as `slashAmount` function no longer needed.
