What does HackerNews think of Lightning-Network?
List of Lightning Network technical issues, bugs, flaws, and exploits.
The main problem in my mind with the Lightning network is that in order increase transaction speed, it is reducing the decentralization by requiring participants to trust the other network operators that they create channels with. For the lightning network to really scale to a global payment system, we would need large central hubs for the payments to route through and you would end up with a poor imitation of the centralized banking system that bitcoin is attempting to avoid.

A transaction is definitionally something that has been written to the blockchain, so no it isn't.
In the case of layered solutions, you're no longer using blockchain. If we want to count uncomitted transactions on a second layer as "reversible", that comes with a host of its own issues, and points out another intrinsic flaw of blockchain: incapable of fulfilling its philosophical purpose, and requires secondary solutions that violate the very core philosophy of the data structure in hopes of overcoming just one of its many issues.
