With SLOTS_PER_EPOCH == 4, TARGET_COMMITTEE_SIZE == 2 and SHARD_COUNT == 2, does this mean we need at least 16 validators?

Not sure if I understand, do we need to specify 16 validators somewhere?

Ah just that in #465 we use 8 validators. Not a problem. Ignore me. 😅

🙈Just realized that I defined GENESIS_SLOT in the chain constants and in the state machine. It seems wrong to treat them as a constant in the state machine and should be parameterizable from the chain. But maybe access this constant from the Serenity config for the time being and address the issue after #896 to resolved.

How about adding SerenityStateMachine? Would it pass the test?

What was wrong?
Part of #488
We need a state machine class and a chain class for the testnet. Unfortunately, for the state machine it requires a specific name. A choice with better taste than foo might be food, and the lowest hanging food outside of the coworking space is the Xiao Long Bao.
How was it fixed?
