Module tree

Reading note commitment trees.

In the functions in this module:

The block write task commits blocks to the finalized state before updating chain with a cached copy of the best non-finalized chain from NonFinalizedState.chain_set. Then the block commit task can commit additional blocks to the finalized state after we’ve cloned the chain.

This means that some blocks can be in both:

• the cached Chain, and
• the shared finalized ZebraDb reference.
