Does the blockchain uses a timestamp to keep track the deadline? Or some kind of logical ordering like the virtual voting in hashgraphs?
Let’s say node A is storing a file on node B. Assume the file file has been sealed properly and proven on B. Then comes the PoSt part where B has to post PoSt for the file for some interval on the chain. Let’s say B sends the proof to the chain within the threshold. In this process (of sending this proof to the chain) it comes across to node C (on the network), and there are some connection problems for C with the rest of the network, such that by the time the proof (from B) has arrived at C it has passed the threshold. How can C be sure that B has send the proof within the threshold?
