Even though lots of people think that blockchain has a great processing technology, bitcoin blockchain can only process a very small amount of transactions compared to other payment methods. For example while visa can process 4000 transactions per second bitcoin can only process seven. Anyone who sent bitcoin in the last 2 years knows how annoying, high transaction fees and long processing time can be, which sparks the question why use bitcoin in the first place, while we have lots of cryptocurrencies that can process transactions very quickly and without any fee. Lightning network is the answer to this question, it aims to solve the bitcoins scalability problem once and for all.
