Lets assume I power-up a new core and join (as validator) to a network of pre-existing other nodes. In addition, to speed things up, I chose to do a partial catchup from one history archive. Now, having synced up, is it possible that my new core has a state that's been tampered with?
In other words, when I perform partial catchup, what are the risks in terms of security?
UPDATE: I'm slightly changing the question to make it more interesting: Suppose the network I join has conspired against me and they've all tampered with the state (the bucketlist) stored on their history to reflect a state that's different than the one I would arrive to by replaying the txs from the genesis block. Is this possible? If it is, then a full catchup does have benefits over a partial one.
