Persistence of important data on the Tangle

How can the transactions in the Tangle be ordered temporally?
Due to the dag structure of the Tangle a complete ordering of transactions is impossible. Therefore, the protocol don't relies on transaction time ordering to determine which of two conflicting ...

How to start a new offline subtangle?
If you want to start a subtangle, you always have to reference existing transactions that don't conflict with the "main" tangle. Otherwise your transactions will never get confirmed. More on that here:...

This is my speculation on how it is done. Due to the fact that the algorithm is randomized and I am not involved in the process, it may as well be a different algorithm.
I don't know who is doing the ...

What happens to a Subtangle if it attaches to an invalid transaction?
When you have a large offline subtangle (which somebody already did the POW for); it is already attached to some (very old) transaction, which has hopefully confirmed until now (when starting an ...

How can the transactions in the Tangle be ordered temporally?
All that we know is that Tf and Tg come after Ta,Tb, Tc
...and the transactions (directly or indirectly) referenced by Ta, Tb, Tc.
That is all the Tangle "knows" about the temporal order of these ...

With IRI version 1.5.2, how does the prevention of lazy tip selection change the tangle's partition tolerance?
IMO, a distinction should be made between different partitioning scenario.
Accidental/occasional partitioning
It's the situation where a portion of the network is temporary disconnected for a ...

What happens to a Subtangle if it attaches to an invalid transaction?
Entire subtangle will be treated as invalid and won't be confirmed. That means you have to reattach all of the transactions.
