5 years ago - Verifiability of messages
- Do not simulate attacks by invalid messages
- Assume validators can verify messages (See https://github.com/LayerXcom/cbc-beacon-chain/issues/1#issuecomment-478194477)
- The total order of messages from the same sender
- Do not reorder messages from the same sender
- Assume this is solved by P2P layer (e.g. "pending" rule)
- DoS attack vector (See https://github.com/LayerXcom/cbc-beacon-chain/issues/8)
- Similarly, in "vote-by-block" consensus, we can assume the total order of all messages
