Lightning Network has been going on for years, I at least recall reading about it in 2017 when I started looking into bitcoin

The idea of the Lightning Network is to allow transactions to exist on a separate layer where in theory transaction fees don't have to exist. & transactions don't have to wait for the next block. This allows for microtransactions etc. There are some blockchain transaction fees involved in creating channels & resolving disputes
