The Lightning Network is said to be able to take the transactions per second figure of Bitcoin and other cryptocurrencies to unprecedented heights of at least 1 million transactions per second.

Compare that with Visa that does around 1,700 transactions per second.

'El Salvador' and Jack Dorsey will be pushing this technology and also we will soon have the book Mastering the Lightning Network by Andreas Antonopoulos, Olaoluwa Osuntokun, and René Pickhardt available on the bookstores' shelves. 

All that is working synergetically to make LN solve all the bitcoin scalability issues.
