How to represent the recursive structure of `Message` and `Block` in implementation?

In the paper

  • Each Message has its justification and
  • Each Block has its parent block

but in the view of data amount efficiency and computational efficiency, sending all recursived data is unrealistic.
Some form of serialization or hashing is needed?

About block, CBC is not so different from other protocols. We can simply include the parent hash in the block. If the message itself is not "pending", then the fork choice won't select unknown block.

About messages, this issue is duplicate of #1 ?

Yep! Storing parent hash in each block (without genesis) is concise.
