I have been reading a lot about this Lightning Network and what it does. But what I still don't know is if this Lightning Network is already being used for Bitcoin or when Bitcoin will start to use it ?
Roasbeef just announced the first Lightning transaction on Bitcoin mainnet today: https://twitter.com/lightning/status/938453165967515648
It was using a multihop payment via all three major implementations (lnd, eclaire, c-lightning).
The three teams are now working on a beta release each. I'd expect this to be released in the next months.
