After years of conceptualization and development, the first Lightning implementations are now in beta. As a result, more nodes are appearing online every day, a growing number of users are opening channels with one another, and some merchants even started to accept Lightning payments.
But of course, these are still the very early days of theLightning Network. While the main implementations are usable and some wallets and other applications are available, Bitcoin’s overlay payment network is projected to improve over the next few years in areas ranging from network architecture to security and usability, and more.
These are some of the more important Lightning projects currently in development.
