I thought Lightning has already been released.
Hum, but its not profitable like other hard fork , Nor a big change in crypto market cap.
The lightning network is not a fork. It's a protocol that allows people to create payment channels that can be settled on chain when they are closed after usage. Only 2 on chain tx's are needed: one to open a ln channel, one to close a ln channel. All other tx's in the channel are off chain, this makes them instant and results in less tx's in the blocks
