Hi, lets assume, that you run a 4 node cluster in two different data centers. Let’s also assume, that each node can mine new blocks and you are using a mining-turnover that is greater 0.
What will happen in a case of a network failure, where both data centers are separated from each other, but internally intact. The chain might create a fork and after both chains are reunited, the blocks added to the „shorter chain“ during the separation phase would be eliminated temporarily.
So here is the question: How will the system manage the off-chain data for blocks in the shorter chain? As I understood transactions in the shorter branch re-enter the memory pool of nodes, which leaves them in the regular situation of waiting for confirmation, but being visible to all nodes. Doesn’t this leave a theoretic possibility of losing data from the mem pool, while the old/new blocks are re-entering the system and the off-chain data is already written?
