A layer two (aka "second layer") is a service where users can send their bitcoins and then transact on the service with reduced impact on bitcoin's blockchain, where users can withdraw their bitcoins ...
Interesting. If we think of LN, we have that: not only ability to withdraw, but also ability to maintain currently held funds, passively, can be violated even without 51% attack but merely through censorship by miners, or even pure unavailability or pricing out through fees > available balance. Hence someone put it in some pithy statement that I can't remember along the lines of "in Lightning censorship resistance is a security requirement" (meh I can't remember exactly but you get it). But then is that overlapping with a 51% attack, or not? I always thought of the latter as specifically referring to attempts to "undo" payments, so changing inclusion and/or ordering of txs. I think I'm trying to say that, with this definition, even LN doesn't count as an L2, does it?
