The Bitcoin Lightning Network is a cryptocurrency protocol that works with blockchain ledger technology. It was created by Joseph Poon and Thaddeus Dryjain in 2017 and is now used to help manage cryptocurrencies such as bitcoin.
Experts refer to the Lightning Network as a “second layer” protocol that works with blockchain to make transactions streamlined between different nodes. Because participants in a transaction do not have to publicize that transaction on the blockchain immediately, this can save some time by using peer-to-peer network design to get around some of the latency in conventional cryptocurrency transactions.
