The Lightning network has developed to another phase, it's in beta now, and it's good news also that Twitter is counting on the Lightning Network's advantages. It doesn't mean that we'll pay with bitcoin at the groceries store next week, but it's a good sign that the technology has the possibilities. If the development continues, the time of the daily payments for bitcoin is not far away anymore...
It is indeed a great development. LN can solve scaling issue of bitcoin network once and for all. As per the last development, it was being tested in the testnet, but since 15th March it has moved to the beta phase. And as correctly mentioned, once it is fully implemented, bitcoin will look more appealing to the store owners worldwide because it will eliminate the waiting time as well as cut down the transaction fees to the lowest possible level.
