The open-source, proof of work blockchain, Litecoin, was designed to mirror Bitcoin’s protocol but with the intention of reducing the transaction time offered by BTC. LTC is the native currency of Litecoin and one of the first cryptocurrencies ever created. Since its introduction in October 2011, Litecoin has always been referred to as the silver to Bitcoin's gold. In terms of supply, Litecoin has a limited mining model set to stop at 84 million. The circulating supply by April 2022 is closing in on 70 million units.
