I have a question about step 1 in permission-less algorithm described in paper ''Algorand Agreement - Super Fast and Partition Resilient Byzantine Agreement".
Let us consider that node i runs into the condition 2, step 1 (see above red rectangle) of period p=2 , and i only received 2t+1 next-votes for value v for period p-1. Nothing else for period p-1 was received. And the block of value v wasn’t received yet.
Now, could i send proposal for v anyway, in absence of the block of value v?
Or i just could send proposal after the corresponding block received.
The latter maybe more safety. But enough is the previous safety?
