Two of the largest cryptocurrency exchanges announced today that they are supporting Segregated Witness, an improvement to the Bitcoin protcol that will allow it to support state channels. Lightning Network is Bitcoin's state channel network; it amounts to a unicast implementation of the Bitcoin procotol, used as a "second layer" to facilitate fast, cheap, anonymous payments atop the old, broadcast version of Bitcoin. It promises to lower Bitcoin transaction fees and make the network's throughput and speed superior to Visa and Mastercard, without diminishing Bitcoin's reliability.

Bitcoin’s transaction fee crisis is over—for now

"Instead of simply increasing the maximum block size, they've focused on a technological upgrade called Segregated Witness that separates cryptographic signatures from the rest of the blockchain data. These signatures aren't counted against that one-megabyte block-size limit, so this is a de facto block-size increase."
