To calculate the deltas correctly, the `process_inactivity_updates` function must be called before the rewards and penalties processing code in order to update the `inactivity_scores` field in the state. This would have required duplicating more logic from the spec in the ncli modules, so I've decided to pay the price of introducing a run-time copy of the state at each epoch which eliminates the need to duplicate logic (both for this fix and the previous one). Other changes: * Fixes for the read-only mode of the `BeaconChainDb` * Fix an uint64 underflow in the debug output procedure for printing balance deltas * Allow Bellatrix states in the reward computation helpers
Introduction
ncli is a set of low level / debugging tools to interact with the nimbus beacon chain specification implementation, simliar to zcli. With it, you explore SSZ, make state transitions and compute hash tree roots.
Tools
- transition: Perform state transition given a pre-state and a block to apply (both in SSZ format)
- hash_tree_root: Print tree root of an SSZ object
- pretty: Pretty-print SSZ object as JSON
