Segwit was just activated on Bitcoin around two weeks ago. Among other things, segwit includes a fix for txn malleability needed to facilitate a lightning network implementation on bitcoin. The lightning network alpha release has been implemented on Litecoin, and has been on the Bitcoin testnet since the beginning of the year. My guess is it will go live before the end of the year, and adoption will ramp up next year.
